Project cost management personnel must be from a new Angle to manage and control the cost of the project. The face of the engineering cost management involves wider and uncertainty is a very strong work, in the process of project implementation will be many unforeseen events, and prevention of these matters only by investment (cost) control is very difficult to do, so the need for the whole process of engineering cost management system of the planning and control. Keywords: Process control; Real estate project; Project cost;1 IntroductionThe more advanced the economy, the pace of urban infrastructure construction and development of more robust, at the same time, building engineering construction enterprise also ushered in the broad space for development. Under such background, the construction engineering construction enterprise how to refine management work to achieve maximum economic efficiency of enterprises gradually came to the attention of many entrepreneurs, and become the key problem affecting the enterprise survival and development. With the continuous development of research and application of the project construction management, dynamic management in the application of modern engineering cost management becomes the main development direction of engineering cost management. Dynamic engineering cost management makes the construction project cost management work can carry on the corresponding adjustment according to the actual circumstance of engineering progress, in order to realize the scientific and precise engineering cost management.2 The analysis of present research situationThe United States, Britain, Japan and other developed countries the research emphasis in the whole lifecycle engineering cost management of construction projects, and more theoretical research in this respect. Whole lifecycle engineering cost management, that is, from the whole life cycle of the project (including construction prophase, construction phase, life and renovation and demolition) set out to consider cost and cost issues, using multidisciplinary knowledge, comprehensive integrated method, attaches great importance to the investment cost, benefit analysis and evaluation, by utilizing the method of engineering economics, mathematical model, the emphasis on prior to the construction of the project, construction period, using the minimum total cost of the maintenance period of stage management theory and methods." Whole lifecycle engineering cost management" is a term by British atoll gowned at don in June 1974 at the royal institution of chartered surveyors of the journal of architecture and quantity surveying quarterly magazine published in the economics of the concept of "3 l" was first proposed. Then, many scholars and practitioners in the whole lifecycle engineering cost management to do a lot of research and progress. O rshan's whole life cycle cost: to compare the construction scheme of tool "is from the perspective of architectural design scheme comparison, explored the construction plan should be fully considered in the design of the project construction cost and operation maintenance cost concepts and ideas, put forward the engineering project cost division method, project cost mathematical model and the uncertainty of the project risk estimation method.3 Analysis of the current status of the construction engineering cost managementProject cost management is the key to guarantee during the construction of the project construction cost control, is an important management means investors the total cost of the project investment. In modern construction project bidding, project cost has become a measure of the bidding enterprise technology, management and cost control, the important factors of construction enterprise's overall strength assessment is of great significance. In recent years as the change of the construction market under the market economy environment, the construction work of constructionenterprise project cost management level has become the influence construction enterprise market competitiveness and economic benefit of the key. Through this period of time the application and popularization of it can be seen that the dynamic engineering cost management can make the enterprise to better deal with the relationship between the time limit for a project, quality and cost, is beneficial to enterprises in a dynamic engineering cost management under the guidance of the theory can improve the effect of cost control. However, because of this theory in the construction enterprises lack of management experience in practical application, eventually led to the enterprises in the implementation of dynamic engineering cost management has many shortcomings.Engineering construction project is under a certain amount of time, cost and quality requirements, to form a certain production capacity (or function) of fixed assets, and according to specific procedure completed one-time task. Real estate project is a type of construction engineering project, compared with the general project, has the characteristics of more complex. The four basic characteristics of real estate project is not only a project (one-time, clarity, integrity, uncertainty), and with a certain procedural, systemic, organizational characteristics such as particularity, diversity policy norms. Real estate project construction cost refers to the construction of a project anticipated or actual spending the entire cost of the investment in fixed assets. Including, equipment and instruments purchase cost, construction installation cost, other cost of engineering construction, the construction period of reserve funds, loan interest, and fixed assets investment adjustment tax.4 Dynamic management and control of the construction project cost4.1 Recognize the importance of dynamic engineering cost managementPush the dynamic management of construction project cost implementation is influenced by the traditional extensive construction management, at present, quite a number of building engineering construction enterprises lack enough understanding of the project cost management work, to dynamic engineering cost management is a lack of understanding, make dynamic engineering cost management in the application and promotion by the block. Against such a situation, the modern building engineeringconstruction enterprises should improve their understanding of, through the improvement of understanding of dynamic engineering cost management, and promote the application of theory of dynamic engineering cost management, promote enterprise project cost management work.4.2 Establish perfect dynamic engineering cost management systemTo promote the implementation of dynamic engineering cost management in order to be able to carry out dynamic engineering cost management theory, improve economic efficiency and market competitiveness of enterprises, the modern building engineering construction enterprises should be based on the dynamic engineering cost management theory to construct perfect project cost management system.To complete the project cost management system specification construction engineering construction process of the project cost management, standardize the construction process in all departments and personnel work, to achieve the goal of construction project cost management.4.3 Construction project cost dynamic management and the analysis of the control pointsUnder the condition of modern market economy, the change of the price will cause the emergence of the artificial expenses. As an important part of the project cost, artificial difference will directly affect the total engineering cost. Therefore, building engineering construction enterprises should according to the market price situation and industry pay corresponding management measures, using basic salaries and wages allowances and benefits way different situations such as transitional adjustment, will be the difference between the artificial cost, the price situation changes on the influence of the artificial cost make scientific adjustment, etc. The implementation of the project cost, the dynamic management of another important content is civil engineering. In compiling process which should increase engineering cost calculation and the actual quantity difference. In the implementation of the project cost management and at the same time, according to the practical situation of the corresponding dynamic adjustment. Through the implementation of dynamic engineering cost management, make the project cost can carry on the adjustmentaccording to the practical situation, to realize the project cost of construction cost.5 ConclusionsTo sum up, the dynamic engineering cost management for modern market economy condition may cause cost change in all kinds of factors in scientific countermeasure. Dynamic implementation of the project cost management for construction engineering construction process of cost control and management in the cost of the establishment and adjustment are given under the guidance of the scientific, for the realization of the project cost control target, project cost management have laid a solid foundation. Modern enterprises should realize the construction of the project cost dynamic management and control the positive influence to the enterprise economic benefit and market competitiveness, with scientific attitude dynamic engineering cost management theory is introduced, and the efficient use of in the process of engineering construction. Through the implementation of dynamic engineering cost management theory, application and management to achieve the ultimate goal of establishment, implementation of engineering cost, improve comprehensive economic efficiency of enterprises.译文房地产项目工程造价管理研究作者: Kim S Y.摘要随着经济的快速发展和基本建设投资规模的不断扩大,房地产市场对建筑工程项目进行全过程工程造价控制的要求越来越迫切。

the stage of the project cost managementAbstract:Project cost management is the basic contents to determine reasonable and effective control of the project cost. Described the current stage of the project cost management situation on the strengthening of the various stages of construction cost management of the importance of and raised a number of key initiatives.Keywords:project cost;the current stage of the project;project cost management;Even under the WTO and China's accession to the world community,China's construction industry how to effectively control construction cost of the construction and management of an important component part. However,the current budget for the construction projects - estimate,budget,Super budget accounts for the "super three" is still widespread and that eventually led to a serious loss of control of project investment. Project cost management is the basic contents to determine reasonable and effective control of the project cost.As the project cost to the project runs through the entire process,stage by stage can be divided into Investment Decision stage,the design and implementation phases. The so-called Project Cost effective control is the optimization of the construction plans and design programs on the basis of in the building process at all stages,use of certain methods and measures to reduce the cost of the projects have a reasonable control on the scope and cost of the approved limits.Engineering and cost management work of the current status of project cost management system was formed in the 1950s,1980s perfect together. Performance of the country and directly involved in the management of economic activities. Provisions in the design stage to different estimates or budget preparation as well as government; Nothing relevant departments to formulate a budget,content,methods and approval,the budget will provide the fixed cost of equipment and materials and fixed price of the budget preparation,approval,management authority,and so on.With the historical process,after recovery,reform and development,formed a relatively complete budget estimate of quota management system. However,as the socialist market economic development,the system's many problems have also exposed. Generally speaking,the budget estimate is based on direct participation in the management of national economic activity as a precondition. Enterprise is not the actual economic entities. Due to the characteristics of the planned economy,and,at the time under the conditions of productivity,will inevitably become a shortage in the economy.In severe shortage of commodities under the conditions,as long as a certain level of investment,will be certain outputs. In this environment,the project planning and technical argumentation there can be no economic analysis. State control of the project cost constitute key factors equipment and materials prices,wages and taxes of artificial distribution. In this relatively stable economic environment,the budget estimate for the system approved project cost,help the government to carry out investment plans to play a major role.As the socialist market economic system established,requires us to predict project investment and control. In recent years,international investment project developed to the requirements of prior pre-control and in the middle of control. China,the traditional practice in an objective light onthe cause decision-making,implementation heavy,light the economy and technology,First,the consequences of victimization,Due to the technical personnel of the project technical and economic concepts and a weak awareness of cost control,cost management makes the quality difficult to raise. Project Cost control is difficult to achieve long-term goals.Second,the various stages of the project management view of the above circumstances,My first academia in the 1980s made the whole process of cost management and control concept,building departments will study the feasibility of projects and the budgets and final accounts to two extended at the request of the corresponding regulations put our cost management concepts and methods referred to a new height.Our task now is to be modern and cost management in line with China's national conditions of the market economy system goal,learn from the advanced experience of the developed countries,and establish sound market economic laws of project cost management system,efforts to increase the project cost levels. An investment decision-making phase of the project cost management construction project investment decision-making stage is proposed project proposals; conduct a feasibility study to determine investment estimation and the final preparation of design task. At this stage,the project's technical and economic decision-making,of the construction project cost of the project after the completion of the economic benefits have a decisive influence,The construction cost is an important stage control.China's current stage of the project cost for the project management for the purpose of clearing price,and focusing only on the construction process of cost control,neglected before the start of the project investment decision-making stage of cost control. Investment decision-making phase of investment projects is estimated an important basis for decision-making. Ithas a direct impact on national economic and financial analysis of the results of the reliability and accuracy. Because of this phase is the preliminary work of projects,the information cannot be fully,comparable works more or less that information accumulated relatively small,estimated inadequate and unscientific. Makes project cost management and cost workers is difficult at this stage do something.The various stages of the project cost control in the decision-making phase project cost control. Right project planning phase of the cost,many owners have the wrong understanding that the lower the cost the better. Cost control is not a unilateral issue,and should be a number of factors,a combination of practical,comprehensive consideration. The construction project investment decision-making stage,the project's technical and economic decision-making,Cost of the project after the completion of the project and the economic benefits,with a decisive role in project cost control is an important stage,rationally define and control the direction of the project cost of accurate positioning and building Optimization guiding role.In the decision-making phase of the most important is to do a good job feasibility study,the work is done well,returns on investment and can form a good proportion. Otherwise,invest more,less effective,resulting in loss of control and waste of investment.At present,some of the projects planned the owners of departure from the subjective desires of a feasibility study on the lack of scientific proof. Feasibility Study untrue,false or engineering functions obtaining the approval of their superiors,actually put into the feasibility study will be awarded in the study for the project after the smooth functioning buried a lot of hidden problems,lead to insufficient follow-up funds for the project andhad to extend the time limit so that the project could not have planned the use of cost-effective,even become hopeless completion of the beard works.Therefore,in order to phase in the investment decision-making effectively control construction costs,we must do the following aspects: Implementationof the construction project and corporate accountability,Construction of the project from planning to implementation of the entire process and the use of the funds to repay responsibilities to the people. in addition to establishing a legal system and the project supervision matching mechanism by the departments in charge of the industry and supervision departments for setting up a monitoring group to oversee the use of funds.A realistic approach to market analysis,to avoid the blindness of the project decision-making,reduces and reduces investment risk. Fully consider building projects in the future market competitiveness,design task more scientific and reliability.Capital financing must have a formal commitment document,the parties must do investment funds in place,and funds must have documents to ensure that the project can be approved after the scheduled implementation. To the various loan conditions should be carefully analyzed to minimize the burden of interest and repayment pressure.To strengthen the engineering geology,hydrology,geology and land,water,electricity,transport,environmental projects such as external conditions for the work of depth to make the investment estimate there are sufficient grounds.Taking extensive investigation and research,comparison of similar projects,seriously functional analysis,multi-program comparison and choice. After full technical appraisal and economic evaluation,and the final technologically advanced,functional and reliable. Reasonable economic projects,thus calculate a more accurate and realistic estimation of theamount of investment,so that the project cost from the start positioning in a more reasonable level.The design phase of the project cost control for a long time,China's building control very effective,- investment projects is not uncommon,this will affect owners of investment returns,it adds to the owners and within budget,as well as difficulties in fund owners,the impact on the future management or the owners make payments in arrears,and so on. Hence,the control of the project cost is of great significance,however the project cost is the primary means of control design,Currently most of the property owners in the design stage seldom works on cost control,and they found that the cost of the design will not have a great impact,it is wrong,on the contrary,Design phase of the project cost control is the most important step. Because it determines engineering design,construction methods,materials and equipment types,models of the project cost is of critical significance,design optimization phase of the program or minor changes,project cost will have a significant impact,Design phase of the project cost control of the total project cost of 70%. Following is how to control the project from design to create the Law: As the owners must design,the design selected on the quality level is a direct impact on the quality of product design level,and the design quality products in the level of direct influence on the pricing of the works. Different design units on the same project design are different. the same item of different design institute works between certain aspects of the project cost on the existence of differences between,We assume that with a design from two different design institute to design,Construction plans after the completion of a requested advisory unit cost to do the budget,certainly different design institute the total cost of the project is absolutely not the same,and most of the difference between the two over 10% even more than30%,and not necessarily high cost than the design of low cost,and good design is often low cost,We all know that different people have different design styles and different levels,the design works naturally,therefore chosen to design units is the control on the first step. Through tender to select the design of the units is a good method,the tender documents to elaborate on this particular aspect of the requirements,cost control targets,and so on.Otherwise,in the subsequent design process design units will put an increase in the cost of the design requirements; through tendering the project design into the market,compared to select the best design units.Promoting the design bidding and design optimization campaign mode design units assessed by experts using scientific group France,in accordance with applicable,economic,aesthetic principles and advanced technology,reasonable structure to meet building energy efficiency and environmental requirements,comprehensive assessment of the merits of the program design,selection of the best determination of the successful program.Successful investment program estimated to be close to the general construction project scope of investment. This means two design contracts will help design the program of choice and competition to ensure that the selected design advanced technology,unique novelty,adaptability,as well as to control the cost of the project. Design units should strive to improve their quality of the project design clever idea,contemporary reducing the project cost on to rack their brains to improve design quality,strive to put the design phase of the project cost control approval of the investment ceiling.Strengthening the design stage of the design phase to strengthen supervision of the Commissioner to determine a reasonable design,maturetechnology,reduction in the construction phase major design changes and changes in the program,in the effective control of the project cost will play a role. 1 to the design of the project if the project supervision to get involved,excluding unfavorable factors may generally is excluded from the 80% errors. In the entire process of building cost control,construction began at best to save and invest 20%,the key lies in the construction phase of the identification and control costs. Supervision of the design phase include : Design Institute under the design drawings and notes help owners deal with different design options for the economy,capital expenditure to develop the preliminary estimates,to ensure that the investment can be most effectively utilized. With the owners of the Commissioner include:According to the Design Institute to provide design drawings and notes to help owners deal with different design options for the economy,capital expenditures to develop the preliminary plan to ensure that investment can be most effectively used; with the owners of different design options,the need to calculate their own materials and equipment to conduct a cost analysis and study,to the design staff costs,to assist them in the investment limit within limits designed to save and invest. To seek a one-time small investment and economic good design program made the most rational economic indicators.Design actively promote the so-called cap limit design,even with the approval of the design task and investment estimates,guarantee the functional requirements of the premise. The preliminary design and control budget,according to the preliminary approval of the total budget for the design and construction design control. Limits,and every one professional,each of whom have a design threshold of a target. In the design process,designers should progress to more programs,design optimization,ensuring that the design is technically advanced and reasonable,innovative,stylish,and do not break the limit investment objectives,thus eliminating theengineering design raise the factor of safety and design standards,or only consider the technical feasibility of the program,rather than economic rationality phenomenon,the project cost to ensure effective control.Also known as the value of value engineering analysis,is a modern scientific management technique,is a new techno-economic analysis,is the product of functional analysis to conserve resources and reduce the cost of the purpose of an effective method. It made up for the traditional cost management simply focus on cost reduction and quality management only emphasizes improving the quality deficiencies,construction is conducive to resolving the long-standing long period,a lot of wastage,poor quality,high-cost problems. Value Engineering laws generally divided into three steps: assessment of the design of object technology and economic Score; Calculation of the target group of technical and economic indicators; calculate the geometric design of the object,on average; From comparison choose the best design.Construction phase of the project implementation unit construction cost management to control the cost of the project is reasonable in the project to meet quality standards premise,in the investment decision-making stage,the design phase and construction phase of the project put the project approval occurred in the control limits,strive in various construction projects rational use of human,material and financial resources to achieve good investment returns and social benefits.The project cost control and management is a dynamic process. The dynamic market economy,to make the investment in the identification and control become more complex,this will require the construction units to the management of project cost to the project runs through the entire process,it is necessary to have a comprehensive focus. The implementation phase of the projects. The implementation phase of the project cost management is theimplementation of the entire process of project management. Project implementation phase of the project cost management can be divided into three parts: the tender management,construction management and settlement management.Bidding for the construction phase of the construction units Bidding system control engineering cost effective means,bid organization can improve the cost-effectiveness of construction projects and ensure the quality of construction projects,shortening the construction cycle return on the investment,construction units can take full advantage of bidding for the effective means of cost control.Construction No. 10 on the 7th ministerial decree issued a "contract with the Construction Contract Pricing Management." clearly pointed out in bidding for projects using inventories. This requires the building of units conducting the tender exercise,in the tender document to include not only the usual content,like tender notes before schedule,tender notes,the conditions of the contract,the contract terms of the agreement,contract format,technical specifications,drawings,tender documents and other reference format,it is also necessary to provide the engineering inventory,Bidding as a reference document of the important components.Construction units in the tender document for the project inventory,in accordance with state or local rules promulgated by the calculation that the reunification of the divided projects,unified measurement units and the reunification of the engineering calculation rules,according to design drawings to be calculated and statistical arranged,obtain the list. Quantities to be followed in the preparation of an objective,impartial,scientific,and rational principle. Compilers must have strong manly budget,and should have certain knowledge of the engineering design and construction experience,and the material and mechanical construction technology forcomprehensive scientific knowledge,in order to calculate the volume of the works without heavy missed. The basis of which must be in accordance with state regulations engineering calculation rules,and the sub-projects division engineering units,and in accordance with design drawings,design essential Love tender documentation requirements are calculated.Quantities of the project should have a testing general,the entries must be simple,while not appear Lousing wrong items Pricing should guarantee the correctness of the project. Should the requirements of the different grades separate engineering division,the situation was different; We may have different prices for the items separately. This requires the preparation of the list compilers,seriously study design drawings,Analysis of the tender documents include the elements of the work and the different technical requirements,all familiar with the process,and to the scene of serious investigation,is forecast to make possible the construction of the case,right will have an impact on the Price of projects to be broken down. In addition,because the project inventories to calculate the amount of the project is not complete engineering and consider the interests of the construction units,clearly paying the price for the same overall price,the quantity list by the number of actual construction is a practical terms.In the evaluation and review of the tender offer should do the units total individual Price quotations and the comprehensive assessment. Price does not meet the requirements of individual shows Price meets the requirements,and the lowest total Price could not explain the single lowest bidder. Bidders often know the total cost to maintain the same circumstances; the project is likely to change smaller projects to lower the price.Changes may be larger projects price increases to achieve the completion of clearing works will be added for the purpose. We would also do price and the corresponding quantity of comprehensive engineeringassessment of the large volume of projects to focus on the price analysis. Price will do with the contents of the work,construction program,a comprehensive technical evaluation process,thereby preferred choice of a construction unit. Construction of the construction phase of the contract cost control basis. Signed tight construction contract,while strengthening the construction contract management can guarantee that the contract price is reasonable,legitimacy and reduce the performance of the contract A,B in disputes and safeguard the interests of both the contract,effective control of the works investment costs.After the signing of the contract,to do the management contract documentation,contract and the supplementary contract agreement until the regular meeting site in minutes. Work contacts such as a single content of a contract extension and explained that the integrity must be preserved,in addition to establishing a technical files,Implementation of the contract for dynamic analysis,results of the analysis to take proactive measures.Construction phase in the construction phase construction plan is based on the budget or Ken works contract price of the target,Ken control the cost of the project. At this stage of conservation has room for a small,but the possibility of waste is great. Thereby to control the cost of the project to give sufficient attention.Construction program to strengthen the comparative technical and economic construction program is construction design of a re - to the contents of the work,a reasonable construction plan,shorten the construction period and ensure the quality of the project,improving economic efficiency,Construction of the program right from the technical and economic evaluation were compared,through qualitative and quantitative analysis,the quality,time,Cost three technical and economic indicators,be rational,and effective use of manpower,material and financial resources,achieve better economic efficiency,good construction management relations,a comprehensive cost management is an important way.Strictly related changes to the project budget control in the proposed budget. Construction of the changes caused by many reasons,including works poorly designed,so that the engineering contract with the drawings provided inconsistent; The current market supply of materials does not meet the standard specifications of the design requirements. These issues have to leave breadwinner project cost factors. Therefore,in the construction process,we must tighten customs change,through no design changes to expand the scale and improve the design standards; increase the construction and contents,the best implementation of the "grade control,visa quota" system. Right to change the design,particularly as it relates to the cost of the design changes must be approved by the design units,construction units scene representatives,supervision engineers common signature,and should be ahead of this type of change,reduce losses,because it has been completed or partially completed project will entail the demolition of the contents,it is bound to cause major changes to the loss. Therefore,the construction units should be assigned to the project cost management professionals Permanent construction site,to grasp at any time. Control project cost of the changes.Works on the scene visa formalities through strict control of the construction project supervision system,the establishment of specialized departments,Professional use of the professional management of projects and to avoid project management personnel just visas,not economic account of the phenomenon. Investment out of control caused serious consequences. To serious change visa procedures to be taken to the building,Supervisor,the construction site together representatives signed the way toensure that change,visa authenticity,legitimacy,economic and avoid fraud and the resulting phenomena arising from the dispute.In the course of construction,the construction units to enhance on-site construction management,supervision and construction side according to the drawings,and strictly control the change of the negotiations,materials substitution,the scene visas,and various additional extra budgetary labor costs for the necessary changes should be done first afterwards,after money,Change event on the timely change in the calculation of the workload and the cost of change occurred to grasp at any time cost of the project level,things to avoid a backlog of work that the true cost of the project.Construction unit representatives to the scene to supervise doing a good job record,particularly concealed records and visas,reduce clearing the passing phenomenon. Many works visa scene is not as serious,works to bring a very large settlement of the trouble,lead to considerable economic losses,the scene strict visa management of the construction phase of the project cost control key.Of project list rigorous review of the project on the review of inventories,Engineers’ monitor list of measures to control the project. BOQ to provide the list of measures is to complete construction projects,occurred in the pre-construction engineering and construction process technology,life and safety aspects of non-engineering projects entities. At this stage because many projects are in construction plans and the construction site of the imperfections on the tender wait until the construction tender of the project design and actual scene have better access. Management Engineer addresses the gathering first-hand information on the original,itemized checking identification,inconsistent make revisions.Control material consumption,rationally define material prices. Cost of the project control materials price control is the main,the cost of materials in engineering often holds substantial proportion,usually accounts for the estimated costs of 70%,representing the direct costs of 80%. It is necessary in the construction phase in strict accordance with the contract amount of material control; material set reasonable prices,so as to effectively control the cost of the project. Market economy material supply a variety of channels,variety and price range materials,construction unit budget management and field personnel should pay close attention to market rates,with the progress of the scene,the market,hand in the construction of the information and materials for the completion of the accounts provide a strong basis.Technology and economic integration,strengthening investment control. Effective control of the investment,from organizational,technical,economic,contracts,and other measures. Therefore,the construction units must strengthen management,engineering and technical personnel of the "economy" concept,the quality of education,Training pragmatic working style,the construction side to help improve construction design,reasonable security,financial,and material resources. Accelerate the pace of work to improve the quality of the projects. Construction should encounter problems in a timely manner with the designer linked to choose both economic and scientific potential solutions,overcome the waste caused by command,to give due attention to the importance of investment in conservation,is responsible for the engineering technician with the combination of economic officers from the tender,contract negotiations,costing the budget,signed paid to the progress of the completion of the accounts,a cost analysis,the whole process management and strictly control the cost of the project.。

外文文献:Project Cost Control: The Way it WorksBy R. Max WidemanIn a recent consulting assignment we realized that there was some lack of understanding of the whole system of project cost control, how it is setup and applied. So we decided to write up a description of how it works. Project cost control is not that difficult to follow in theory.First you establish a set of reference baselines. Then, as work progresses, you monitor the work, analyze the findings, forecast the end results and compare those with the reference baselines. If the end results are not satisfactory then you make adjustments as necessary to the work in progress, and repeat the cycle at suitable intervals. If the end results get really out of line with the baseline plan, you may have to change the plan. More likely, there will be (or have been) scope changes that change the reference baselines which means that every time that happens you have to change the baseline plan anyway.But project cost control is a lot more difficult to do in practice, as is evidenced by the number of projects that fail to contain costs. It also involves a significant amount of work, as we shall see, and we might as well start at the beginning. So let us follow the thread of project cost control through the entire project life span.And, while we are at it, we will take the opportunity to point out the proper places for several significant documents. These include theBusiness Case, the Request for (a capital) Appropriation (for execution), Work Packages and the Work Breakdown Structure, the Project Charter (or Brief), the Project Budget or Cost Plan, Earned Value and the Cost Baseline. All of these contribute to the organization's ability to effectively control project costs.FootnoteI am indebted to my friend Quentin Fleming, the guru of Earned Value, for checking and correcting my work on this topic.The Business Case and Application for (execution) FundingIt is important to note that project cost control is most effective when the executive management responsible has a good understanding of how projects should unfold through the project life span. This means that they exercise their responsibilities at the key decision points between the major phases. They must also recognize the importance of project risk management for identifying and planning to head off at least the most obvious potential risk events.In the project's Concept Phase• EvEry projEct starts with somEonE idEntifying an opportunity or need. That is usually someone of importance or influence, if the project is to proceed, and that person often becomes the project's sponsor.• to dEtErminE thE suitability of thE potEntial projEct, most organizations call for the preparation of a "Business Case" and its"Order of Magnitude" cost to justify the value of the project so that it can be compared with all the other competing projects. This effort is conducted in the Concept Phase of the project and is done as a part of the organization's management of the entire project portfolio.• thE cost of thE work of preparing the Business Case is usually covered by corporate management overhead, but it may be carried forward as an accounting cost to the eventual project. No doubt because this will provide a tax benefit to the organization. The problem is, how do you then account for all the projects that are not so carried forward?• if thE businEss casE has sufficiEnt mErit, approval will bE givEn to proceed to a Development and Definition phase.In the project's Development or Definition Phase• thE objEctivE of t he Development Phase is to establish a good understanding of the work involved to produce the required product, estimate the cost and seek capital funding for the actual execution of the project.• in a formalizEd sEtting, EspEcially whErE big projEcts arE involved, this application for funding is often referred to as a Request for (a capital) Appropriation (RFA) or Capital Appropriation Request (CAR).• this rEquirEs thE collEction of morE dEtailEd rEquirEmEnts and data to establish what work needsto be done to produce the required product or "deliverable". From this information, a plan is prepared in sufficient detail to give adequate confidence in a dollar figure to be included in the request.• in a lEss formalizEd sEtting, EvEryonE just triEs to muddlE through.Work Packages and the WBSThe Project Management Plan, Project Brief or Project Charter• if thE dElivErablE consists of a numbEr of diffErEnt ElEmEnts, thEsE are identified and assembled into Work Packages (WPs) and presented in the form of a Work Breakdown Structure (WBS).• Each wp involvEs a sEt of activitiEs, thE "work" that is plannEd and scheduled as a part of the Project Management Plan. Note, however, that the planning will still be at a relatively high level,and more detailed planning will be necessary during execution if the project is given the go ahead.• this projEct managEmEnt plan, by thE way, should bEcomE thE "bible" for the execution phase of the project and is sometimes referred to as the "Project Brief" or the "Project Charter".• thE cost of doing thE various activitiEs is thEn EstimatEd and thEsE estimated costs are aggregated to determine the estimated cost of the WP. This approach is known as "detailed estimating" or "bottom up estimating". There are other approaches to estimating that we'll come to in a minute. Either way, the result is an estimated cost of the totalwork of the project.Note: that project risk management planning is an important part of this exercise. This should examine the project's assumptions and environmental conditions to identify any weaknesses in the plan thus far, and identify those potential risk events that warrant attention for mitigation. This might take the form of specific contingency planning, and/or the setting aside of prudent funding reserves.Request for capitalConverting the estimate• howEvEr, an EstimatE of thE work alonE is not sufficiEnt for a capital request. To arrive at a capital request some conversion is necessary, for example, by adding prudent allowances such as overheads, a contingency allowance to cover normal project risks and management reserves to cover unknowns and possible scope changes.• in addition, it may bE nEcEssary to convErt thE Estimating data into a financial accounting formatthat satisfies the corporate or sponsor's format for purposes of comparison with other projects and consequent funding approval.• in practicE all thE data for thE typE of "bottom up" approach just described may not be available.In this case alternative estimating approaches are adopted that provide various degrees of reliability in a "top down" fashion. Forexample:Order of Magnitude estimate – a "ball park" estimate, usually reserved for the concept phase onlyAnalogous estimate – an estimate based on previous similar projects Parametric estimate –an estimate based on statistical relationships in historical data• whichEvEr approach is adoptEd, hopEfully thE sum thus arrivEd at will be approved in full and proves to be satisfactory! This is the trigger to start the Execution Phase of the projectNote: Some managements will approve some lesser sum in the mistaken belief that this will help everyone to "sharpen their pencils" and "work smarter" for the benefit of the organization. This is a mistaken belief because management has failed to understand the nature of uncertainty and risk in project work. Consequently, the effect is more likely to result in "corner cutting" with an adverse effect on product quality, or reduced product scope or functionality. This often leads to a "game" in which estimates are inflated so that management can adjust them downwards. But to be fair, management is also well aware that if money is over allocated, it will get spent anyway. The smart thing for managements to do is to set aside contingent reserve funds, varying with the riskiness of the project, and keep that money under careful control.Ownership of approved capital• if sEnior managEmEnt approvEs thE rfa as prEsEntEd, thE sum in question becomes the responsibility of the designated project sponsor. However, if the approved capital request includes allowances such as a "Management Reserve", this may or may not be passed on to the project's sponsor, depending on the policies of the organization.• for thE approvEd rfa, thE projEct sponsor will, in turn, further delegate expenditure authority to the project's project manager and will likely not include any of the allowances. An exception might be the contingency allowances to cover the normal variations in work performance.• thE nEt sum thus arrivEd at constitutes the project manager's Approved Project Budget.Note: If management does not approve the RFA, you should not consider this a project failure. Either the goals, objectives, justification and planning need rethinking to increase the value of the project's deliverables, or senior management simply has higher priorities elsewhere for the available resources and funding.The Project's Execution PhaseThe project manager's Project Budget responsibility• oncE this approvEd projEct budgEt is rElEas ed to the project manager, a reverse process must take place to convert it into a working control document. That is, the money available must be divided amongstthe various WBS WPs that, by the way, have probably by now been upgraded! This results in a project execution Control Budget or Project Baseline Budget, or simply, the Project Budget. In some areas of project management application it is referred to as a Project Cost Plan.• on a largE projEct whErE diffErEnt corporatE production divisions are involved, there may be a further intermediate step of creating "Control Accounts" for the separate divisions, so that each division subdivides their allocated money into their own WBS WPs.• obsErvE that, sincE thE total projEct budgEt rEcEivEd formal approval from Executive Management, you, as project manager, must likewise seek and obtain from Executive Management, via the project's sponsor, formal approval for any changes to the total project budget. Often this is only justified and accepted on the basis of a requested Product Scope Change.• in such a casE thE projEct's sponsor will EithEr draw down on thE management reserve in his or her possession, or submit a supplementary RFA to upper management.• now that wE havE thE projEct budgEt monEy allocatEd to Work Packages we can further distribute it amongst the various activities of each WP so that we know how much money we have as a "Baseline" cost for each activity.• this providEs us with thE basE of rEfErEncE for thE cost controlfunction. Of course, depending on the circumstances the same thing may be done at the WP level but the ability to control is then at a higher and coarser level.Use of the Earned Value technique• if wE havE thE nEcEssary dEtails anothEr control tool that wE can adopt for monitoring ongoing work is the "Earned Value" (EV) technique. This is a considerable art and science that you must learn about from texts dedicated to the subject.• but EssEntially, you takE thE costs of thE schEdulE activitiEs and plot them as a cumulative total on the appropriate time base. Again you can do this at the activity level, WP level or the whole project level. The lower the level the more control information you have available but the more work you get involved in.The Cost Baseline• this plannEd reference S-curve is sometimes referred to as the "Cost Baseline", typically in EVparlance. That is, it is the "Budgeted Cost of Work Scheduled" (BCWS), or more simply the "Planned Value" (PV).• Observe that you need to modify this Cost Baseline every time there is an approved scope change that has cost and/or schedule implications and consequently changes the project's Approved Project Budget.• now, as thE work progrEssEs, you can plot thE "actual cost of workPerformed" (ACWP or simply "Actual Cost" - AC).• you can plot othEr things as wEll, sEE diagram rEfErrEd to abovE, and if you don't like what you see then you need to take "Corrective Action".CommentaryThis whole process is a cyclic, situational operation and is probably the source of the term "cycle" in the popularly misnamed "project life cycle".As an aside, the Earned Value pundits offer various other techniques within the EV process designed to aid in forecasting the final result, that is, the "Estimate At Completion" (EAC). EAC is what you should really be interested in because it is the only constant in a moving project. Therefore, these extended EV techniques must be considered in the same realm of accuracy as top-down estimating. They are useful, but only if you recognize the limitations and know what you are doing!But, as we said at the beginning, it is a lot more difficult to do in practice –and involves a significant amount of work. But, let's face it, that's what project managers are hired for, right?中文译文:项目成本控制:它的工作方式R.马克斯怀德曼我们在最近的咨询任务中意识到,对于整个项目成本控制体系是如何设置和应用的这个问题,我们仍有一些缺乏了解。

工程造价论文中英文资料对照外文翻译Risk Analysis of the International Construction ProjectABSTRACTThis analysis used a case study methodology to analyse the issues surrounding the partial collapse of the roof of a building housing the headquarters of the Standards Association of Zimbabwe (SAZ). In particular, it examined the prior roles played by the team of construction professionals. The analysis revealed that the SAZ’s traditional construction project was generally characterized by high risk. There was a clear indication of the failure of a contractor and architects in preventing and/or mitigating potential construction problems as alleged by the plaintiff. It was reasonable to conclude that between them the defects should have been detected earlier and rectified in good time before the partial roof failure. It appeared justified for the plaintiff to have brought a negligence claim against both the contractor and the architects. The risk analysis facilitated, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. It further served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. Clients do not want surprise, and are more likely to engage in litigation when things go wrong.KEY WORDS:Arbitration, claims, construction, contracts, litigation, project and risk The structural design of the reinforced concrete elements was done by consulting engineers Knight Piesold (KP). Quantity surveying services were provided by Hawkins, Leshnick & Bath (HLB). The contract was awarded to Central African Building Corporation (CABCO) who was also responsible for the provision of a specialist roof structure using patented “gang nail” roof trusses. The building construction proceeded to completion and was handed over to the owners on Sept. 12, 1991. The SAZ took effective occupation of the headquarters building without a certificate of occupation. Also, the defects liability period was only three months .The roof structure was in place 10 years before partial failure in December 1999. The building insurance coverage did not cover enough, the City of Harare, a government municipality, issued the certificate of occupation 10 years after occupation, and after partial collapse of the roof .At first the SAZ decided to go to arbitration, but this failed to yield an immediate solution. The SAZ then decided to proceed to litigate in court and to bring a negligence claim against CABCO. The preparation for arbitration was reused for litigation. The SAZ’s quantified losses stood at approximately $ 6 million in Zimbabwe dollars (US $1.2m) .After all parties had examined the facts and evidence before them, it became clear that there was a great probability that the courts might rule that both the architects and the contractor were liable. It was at this stage that the defendants’ lawyers requested that the matter be settled out of court. The plaintiff agreed to this suggestion, with the terms of the settlement kept confidential .The aim of this critical analysis was to analyse the issues surrounding the partial collapse of the roof of the building housing the HQ of Standard Association of Zimbabwe. It examined the prior roles played by the project management function and construction professionals in preventing/mitigating potential construction problems. It further assessed the extent to which the employer/client and parties to a construction contract are able to recover damages under that contract. The main objective of this critical analysis was to identify an effective risk management strategy for future construction projects. The importance of this study is its multidimensional examination approach.Experience suggests that participants in a project are well able to identify risks based on their own experience. The adoption of a risk management approach, based solely in past experience and dependant on judgement, may work reasonably well in a stable low risk environment. It is unlikely to be effective where there is a change. This is because change requires the extrapolation of past experience, which could be misleading. All construction projects are prototypes to some extent and imply change. Change in the construction industry itself suggests that past experience is unlikely tobe sufficient on its own. A structured approach is required. Such a structure can not and must not replace the experience and expertise of the participant. Rather, it brings additional benefits that assist to clarify objectives, identify the nature of the uncertainties, introduces effective communication systems, improves decision-making, introduces effective risk control measures, protects the project objectives and provides knowledge of the risk history .Construction professionals need to know how to balance the contingencies of risk with their specific contractual, financial, operational and organizational requirements. Many construction professionals look at risks in dividually with a myopic lens and do not realize the potential impact that other associated risks may have on their business operations. Using a holistic risk management approach will enable a firm to identify all of the organization’s business risks. This wi ll increase the probability of risk mitigation, with the ultimate goal of total risk elimination .Recommended key construction and risk management strategies for future construction projects have been considered and their explanation follows. J.W. Hinchey stated that there is and can be no ‘best practice’ standard for risk allocation on a high-profile project or for that matter, any project. He said, instead, successful risk management is a mind-set and a process. According to Hinchey, the ideal mind-set is for the parties and their representatives to, first, be intentional about identifying project risks and then to proceed to develop a systematic and comprehensive process for avoiding, mitigating, managing and finally allocating, by contract, those risks in optimum ways for the particular project. This process is said to necessarily begin as a science and ends as an art .According to D. Atkinson, whether contractor, consultant or promoter, the right team needs to be assembled with the relevant multi-disciplinary experience of that particular type of project and its location. This is said to be necessary not only to allow alternative responses to be explored. But also to ensure that the right questions are asked and the major risks identified. Heads of sources of risk are said to be a convenient way of providing a structure for identifying risks to completion of a participant’s part of the project. Effective risk management is said to require amulti-disciplinary approach. Inevitably risk management requires examination of engineering, legal and insurance related solutions .It is stated that the use of analytical techniques based on a statistical approach could be of enormous use in decision making . Many of these techniques are said to be relevant to estimation of the consequences of risk events, and not how allocation of risk is to be achieved. In addition, at the present stage of the development of risk management, Atkinson states that it must be recognized that major decisions will be made that can not be based solely on mathematical analysis. The complexity of construction projects means that the project definition in terms of both physical form and organizational structure will be based on consideration of only a relatively small number of risks . This is said to then allow a general structured approach that can be applied to any construction project to increase the awareness of participants .The new, simplified Construction Design and Management Regulations (CDM Regulations) which came in to force in the UK in April 2007, revised and brought together the existing CDM 1994 and the Construction Health Safety and Welfare (CHSW) Regulations 1996, into a single regulatory package.The new CDM regulations offer an opportunity for a step change in health and safety performance and are used to reemphasize the health, safety and broader business benefits of a well-managed and co-ordinated approach to the management of health and safety in construction. I believe that the development of these skills is imperative to provide the client with the most effective services available, delivering the best value project possible.Construction Management at Risk (CM at Risk), similar to established private sector methods of construction contracting, is gaining popularity in the public sector. It is a process that allows a client to select a construction manager (CM) based on qualifications; make the CM a member of a collaborative project team; centralize responsibility for construction under a single contract; obtain a bonded guaranteed maximum price; produce a more manageable, predictable project; save time and money; and reduce risk for the client, the architect and the CM.CM at Risk, a more professional approach to construction, is taking its place along with design-build, bridging and the more traditional process of design-bid-build as an established method of project delivery.The AE can review the CM’s approach to the work, making helpful recommendations. The CM is allowed to take bids or proposals from subcontractors during completion of contract documents, prior to the guaranteed maximum price (GMP), which reduces the CM’s risk and provides useful input to design. The procedure is more methodical, manageable, predictable and less risky for all.The procurement of construction is also more business-like. Each trade contractor has a fair shot at being the low bidder without fear of bid shopping. Each must deliver the best to get the projec. Competition in the community is more equitable: all subcontractors have a fair shot at the work .A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes. As long as the subcontractors are within the GMP they are reimbursed to the CM, so the CM represents the client in negotiating inevitable changes with subcontractors.There can be similar problems where each party in a project is separately insured. For this reason a move towards project insurance is recommended. The traditional approach reinforces adversarial attitudes, and even provides incentives for people to overlook or conceal risks in an attempt to avoid or transfer responsibility.A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes.

It did appearjustified for the plaintiff to have brought a negligence claim against both the contractor and the architects.In many projects clients do not understand the importance of their role in facilitating cooperation and coordination; the design is prepared without discussion between designers, manufacturers, suppliers and contractors. This means that the designer can not take advantage of suppliers’ or contractors’ knowledge of build ability or maintenance requirements and the impact these have on sustainability, the total cost of ownership or health and safety .This risk analysis was able to facilitate, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. This work also served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense.

中英文对照外文翻译(文档含英文原文和中文翻译)The significance of control construction costs manages on entireprocessFirst, The necessary of control construction costs manages on entire process Talk about the management and the control on construction costs, that the field we are just accustomed to is thought of is a project advance in final account. Indeed , right away at present system and reality,what the job of that the management and the control on construction costs is advance in final account. Be that in advance, the people who work on final account according that already be ascertaied of the working drawing to calculate project amounts,apply a quota mechanically, the meter mechanically fetching cost, or designing that according to the drawing sheet and construction organization after construction is over as well as the scene construction visa takes notes weaves the final account being completed. This is necessary , useful no doubt. But we must see that when pre-final accounts personnel weave working drawing budget or the final account being completed, the construction plan and thedesign paper already determined. But construction being to take according to picture as principle, so then in advance, job done by final account personnel is only the change secretly scheming against cost produced by design alteration and prevents upvaluation from calculating boldly. But suppose the project is unreasonable on economy, there is a fault in decision-making; suppose designing a scheme feasible or be not optimum on the technology; the final account personnel can do nothing for sb then in advance. Job of final account personnel does accounts in advance only under just saying system currently in effect, after the event , can only reflect already complete project amounts inactively , can only reflect design and be under construction passively. This evidently is single-faceted , insufficient , we must carry out the entire proceeding supervisory control on the construction costs of building a project.Concrete conditions of union our country, cost of construction manages have problems as follows:1、Be not enough to take investment decision into the stage of construction costs seriously charge indeed.Investment decision is to produce the construction costs headstream, This one stage blow the expense at take up the total investment forehead about 0.5%~3%,but that can have an effect to raise the project benefit of investment. That the project carries out rational choice on construction is that resource carries out direct , the most important optimization deploy means on economy , project benefit of investment affects efficiency and beneficial result to entire national economy. The developed country charges attach importance to control on investment decision stage construction costs,and costs not stinting big capital of money making the studies on the stage of carrying out investment decision energetically, make relatively comparatively accurate construction costs , go along the controlFor a long time, there is the grave phenomenon investing in swelling in engineering construction of our country,bring the limit for a project feeling longer and longer, construction costs is higher and higher. The cause of that is short of the effective basis of the building of earlier stage ascertaining construction costs, only basis the already completed according to the expert , decision-makers draw lessons to estimate the project construction costs. Because a lot of factor effects, the“three surpass " phenomenon very common, there are main cause as follows:(1) personal factor brings about rough estimate lessening(2) equipment composes in reply material price's not working out according to market quotations.(3) construction units bring forward the too high for exceeding a design criterion 2、The design stage of construction costs is not under the control of strictThe design stage is the faucet in that project construction costs controls. After the investment decision is be made rationally , that is the process of plan the technology and organic together economly . Effective control the cost of construction requires strictly and all-round in the enginee designing . Engineering design of current our country also puts move bidding system , fair competition into practice , cost of construction looks on control engineering effective to design stage as one of thestandard choosing main part being hit by the bid unit , cost of construction carries out the administration controlling on the entire proceeding .Our country major part design that the unit carries out thorough analysis lack on construction project technology and economy , big multiple technologies make light of economy in design but at present , design that the personnel is responsible seemingly only to design project mass , are concerned with the construction costs height not very. Optimize a design plan to such an extent as having no way to pass, the first step designs , the rough estimate gets to the effect controlling general cost of construction's establishment. Mass and depth that engineering design pursues etc. is also insufficient , amounts project mistakes in amounts project detailed lists calculates , misses and not calculating, can't arouse increasing by estimating a project momentary, the mass making a tender work is difficult to ensure that , have no way to have an effect to control construction costs asa result also.3、Has not adopt the amounts project detailed list quoted price way being applied or used universally on the international all roundAdopt the amounts project detailed list quoted price way being put into use commonly on the international , is that our country construction costs system reforms and cause the inevitable trend reforming to bid system in invitation to bid tender.One of important act carrying out project public bidding system being to build socialist market economy and to perfect construction market operating mechanism in construction field. After the construction project tender is carried out all round in our country, the effect is obvious in the respect of shortening the mass building a time limit for a project , ensuring a project , reducing construction costs , boycotting an unhealthy tendency. Have ensured the invitation to bid people and bidder's lawful rights and interests also effectively. With the socialist market economy uninterrupted growth,the original tender stage puts the budget quota valuation pattern into practice already doing not adapting , adopt the amounts project detailed list quoted price way being put into use commonly on the international to carry out a tender is an inevitable trend. Ministry of Construction has issued amounts project detailed list valuation method , amounts project detailed list valuation has been in construction project tender job , person has provided project quantity from invitation to bid according to national unification project amounts calculation regulation , quoted price, and classics have judged the reason bidder autonomously trying the at a low price middle bid construction costs valuation pattern.That carrying out amounts project detailed list valuation method is one important measure of item of construction costs deepen the reform, is standard tender behavior effective measure. This method is beneficial to changing over taking that "amounts" ", "price" are "quota-consuming" as dominant static state managing a pattern , make project amounts in detailed list not enter competition, competition being confined to price only; Beneficial to rightness appraises enterprise strength; Project mass beneficial to ensuring that, reduces construction costs; May cut down the physical labour complicated and overloaded repeating the amounts calculating a project; Facilitate the tender quoted price job; Argue with the dispute back and forth in cutting down project settlement; Receive a track step by step with the convention "controllingamounts , guiding price , competing for a fee's on" the international, deepen the reformation that project valuation manages mainly according to the marketplace changes development, taking one's place on the international market for our country contracts business creates condition.4、The stage being under construction controls lack to construction costsWant to have strict control design alteration too in the stage being under construction. Guard the pass though that working drawing appears in joint trial or are able to have all sorts of problems, but call for to design a branch in the process of construction hard to avoid is strict out of the construction works complexity, the situation changing after avoiding doing first, is also that the weight avoiding break a rough estimate , effective control engineering of construction costs cost of construction plays with a link. At the same time, the sharpening contract manages , ensures equality and mutual benefit issuing contract of method and contracting method.5、The construction costs being completed settling a stage's controls a project inefficientlyThat the final account being completed is that entire construction costs is under the control of the most important one is encircled by construction works. How the final account being completed can reflect actual entire project cost of construction honestly , have also reflected the ability issuing contract of method and contracting method to construction costs administration , have finished handling a project in time the final account being completed must collect , arrange settling a data , pursuing , designing the certificate material changing notice , various warning including that the project is completed and so on being completed. These data collecting must pay attention to whose validity with obtaining evidence, specimen seal impression having designing personnel's signature and being related to if the design alteration advice note must be made known to lower levels by plain design organ. Scene inspection and control visa must label seal and the ratification going on a punitive expedition to such that designing a personnel etc. having construction site person in charge of first party. Great majority our country construction projects are completed in the project being under construction when the final account, during the period of the final account being completed contracting method , are are under construction contracting method calculating commonly much in the book being completed winding up an account , are issue contract of haggie just inexhaustible in devices and schemes , are dispute over trifles phenomenon is grave , project settlement drags repeatedly , some confirmation having drug once and , greatly, affecting engineering construction project sigmatism and building construction costs.A construction project includes the following procedure from brewing , planning , designing that to establishing completion and commissioning: Be that the project letter of advice stage , feasibility appraise the stage , design stage , the stage being under construction , acceptance check stage and the queen being completed estimate that.Correspondingly, the construction costs ascertaining that and the project construction phase job look at and appraise the stage adapting to , several being allotted in general for the following: The investment studying stage establishment inthe project letter of advice and feasibility is estimated, design stage establishment designs a rough estimate in the first step, budget designing that the stage weaves working drawing in working drawing, budget builds ampere of construction costs face to face with working drawing for basis tender project engineering contract, price is also that the form ascertains that with the business contract; Project amounts putting stage into practice being going to be completed according to contracting reality in project, takes contract price as basis , considers cost of construction rise aroused by inflation of prices at the same time , considers the project and cost being difficult to estimate that to designing middle but happening in putting stage reality into practice , the example is ascertained estimating price; All-in cost costing in the reality being completed checking and accepting a stage , assembling into engineering construction process middle all round, weaves the final account being completed , embodies the actual cost of construction that a construction project according to the facts."Four guess that two-valence "is interrelated , the former restricts the latter , the latter supplements the former.What is called, build the construction costs administration and control, it is the occurrence contracting the stage and construction in the investment decision stage , design stage , construction project putting stage into practice with construction construction costs to control within the cost of construction quota O. K. , correcting the deviation happening at any time, to ensure that the project manages the target realization , get fairly good benefit of investment and social benefits in an attempt being able to use manpower and material resources, financial resources rationally in building a project one by one.Second, the importance of the investment decision-making stage of project cost controlConstruction projects in the investment decision-making stage, the project of the techno-economic decision-making, as well as the cost of construction projects completed and put into production after the project cost-effective, have a decisive impact on the construction project cost control is an important stage. Project cost management as a decision-making stage in the feasibility study report shall be prepared, and economic evaluation of the proposed project, select the technically feasible and economically the construction of example programs and to optimize the construction program on the basis of the preparation of high-quality items investment is estimated that the project construction so that the real control of the project has played the role of total investment.The impact of the decision-making phase of the project cost are the main factors: a, the determine level of construction standards; b, the choice of built-up areas; c, building location (site) selection; d, project the economic scale; e, technology selection f, equipment selection .Such as the choice of built-up areas, there is a basic principle, that is close to raw materials, fuel and consumer principles. This project completed and put into production, you can avoid the raw materials, fuels, and finished the long-haul transport, reduce costs, lower costs; transportation distance may be shortened to reduce the flow of time, speed up cash flow and is conducive to business. If theproject's economic size, economies of scale, product standard is a reasonable means of production volume, a number of products under certain conditions, was "increasing returns" of economic phenomena, that is, with the expansion of production volume, unit cost reduction, revenue increase.Therefore, in order to phase in the investment decision-making control over project cost effective, we must do a good job in the following areas:(1) the implementation of construction project legal person responsibility system, the construction project from planning to implementation of the whole process of the use of funds and repayment responsibilities to people and projects at the same time establish a system of matching corporate oversight mechanisms, by the competent authorities and supervision of the industry sector establishment of a monitoring group to oversee the use of project funds.(2) to conduct market analysis and seeking truth from facts, to avoid the blindness of the project decision-making, reduce risk and lower investment, give full consideration to construction projects in the future competitiveness of the market so that more scientific book design and reliability(3) Capital financial capital must be committed to a formal document, investment funds must be put in place the parties, there must be a funding document to ensure that projects are implemented on schedule after approval. Conditions of the loans should be carefully analyzed and compared to minimize the interest burden and repayment pressure.(4) Strengthening of engineering geology, hydrogeology, as well as land, water, electricity, transport, environmental protection projects such as the work of the depth of the external conditions, so that there is sufficient basis to estimate the investment. At the same time, extensive research should be to compare similar projects, a serious functional analysis, comparison and choice of multi-program, a full-scale technical feasibility studies and economic evaluation, the finalization of technologically advanced, reliable, economical and rational project construction program in order to estimate more accurate and realistic estimate of the amount of investment in order to make the project cost from the start position in a more reasonable level.Third, the design phase of the importance of project cost controlMake investment decisions in the project, the project cost control is the key to the design. Design is in the technical and economic implementation of the proposed project to conduct a comprehensive arrangement, is also planning the construction process. Technologically advanced, economical and rational design can reduce the project construction period, savings investment, to improve efficiency. According to expert analysis, design fee generally equal to the construction of the project life-cycle cost of less than 1%, which costs less than 1% of project cost accounts for the impact of degrees above 75%. Because of the general construction projects, selection of materials and equipment accounted for more than 50% of the cost of the project, and in the design phase of architectural forms, structural type, the selection of equipment and materials have been identified in the construction of post-implementation phase, the impact of the project cost a small (10 % or less). This shows that the design quality is crucial to the entire projectThe same construction project, the same single unit of work can have different programs, which have different costs, it is therefore necessary to meet the function under the premise of doing a number of options, through technical comparison, economic analysis and efficiency evaluation, selection of technology selection into the application of economic and rational design, that is, the process of design optimization. Often used to optimize the design of the program, also known as the value of value engineering analysis, that is, as far as possible in meeting the functionality or improve the function of the premise, as far as possible to reduce costs.Occurred in the cost of all parts of the application of value engineering, construction investment will require a lot of people, financial, and material, and thus the value of engineering construction works great. For a rather mature and effective management methods, value engineering in a number of works have been widely used in construction.In the engineering design phase correctly handle the technical and economic relationship between the unity of opposites, we can control the key to investment, design and cost management must work closely with staff to make a lot of the technical and economic comparison, in the reduction and control of project efforts, engineering Cost management in the design process should be timely investment analysis on the comparison, the cost of information feedback and dynamic impact on the design, in order to ensure effective control over investment.At the design stage to project cost control should focus on the following aspects.(1) to promote the design and the design of the bidding campaign optimization design approachThe assessment team of experts using scientific methods, in accordance with applicable, economic, aesthetic principles, as well as technologically advanced, well-structured to meet the building energy saving and environmental requirements, a comprehensive assessment of the merits of design, selection of the best in determining the successful program. Estimates of selected investment program in general to be close to the scope of construction projects. The design of these two methods both contract design choice and competition, to ensure selection of the design of technologically advanced, innovative and unique, adaptable, and help control project cost. Design units should strive to improve their own quality, clever engineering design ideas, great care, in order to reduce the project cost more than their brains in order to improve design quality, and strive to put at the design stage in the approval of project cost control within the investment limits.(2) actively pursuing the design limitThe so-called cap design, is in accordance with the approved design of the book and investment is estimated that in the guarantee under the premise of the functional requirements. Preliminary design and budget control, in accordance with the approved budget for the preliminary design and total control of the construction design. Through the ceiling design, every professional, every designer has a target investment limit. During the design process, designers should be more into the program to compare and optimize the design, Not only to ensure that technically advanced and reasonable design, innovative aesthetics, but also the investment limit is not exceededthe target in order to put an end to the design of the project to raise the factor of safety and design standards, or only consider the feasibility of technical solutions, rather than the phenomenon of economic rationality to ensure effective cost control.(3) the implementation of the design of reward and punishment systemIn order to limit the design of the implementation into practice, the limit should be set up and sound system designed to reward and punishment. To limit the design is done well, cost savings and control of investment there is the effectiveness of the project legal person should be given appropriate incentives and design units. Design to limit the development of the internal design of assessment and incentive methods to limit attention to the design, made to save investment and effective cost control offices and the significant achievements of individuals, should be rewarding. Do not attach importance to limit the design, do not take measures to save the investment, resulting in more than a design limit investment offices and individuals should be given to economic penalties. Do reward and encourage designers to design deep potential economic importance to design the control of a reasonable project cost will be a major breakthrough.Fourth、the cost control of the implementation phase of construction project1, the bidding process stageThe implementation of construction project bidding is effective means of construction projects to control the implementation phase of the project cost. If we want To do a good job for bidding, the first we should make sure that qualification is clearance, and resolutely put an end to bribery, such as all the Phenomenon about destruction of all bidding discipline; Secondly, we should strengthen the bid management, to ensure the accuracy and confidentiality of bid preparation; Third, make sure the method of Evaluation and Calibration are Scientific .when select the successful projects as a standard we should concern about the reasonable, short period, reputable companies, construction considerations such as experience. when we evaluation, the first is technical standard assessment, the follow is business assessment,this can ensure open, fair and just.2, the construction phaseIn the construction phase construction ,the goles based on project budget or contract price of Civil works and installation works and project cost control of Civil works and installation works. At this stage the scope for savings has been small, but it is likely to lead to waste,this make us give them adequate attention for the control of project cost.(1) strengthen the technical and economic comparison of construction programConstruction is an important work of the design of constructing orgnization. Reasonable constructing program can shorten the period of constructing, ensure the quality of the project and enhance economic efficiency. Comparing and analysing the constructing program from technical and economic view and comparing the three techno-economic index of the quality, duration and cost through qualitative analysis and quantitative analysis can take good use of manpower, material and financial resources, achieving better economic benefits. Consequently, good construction management is an important way of all-round cost management.(2) a sound system design change Examination and approval systemIf design subject need to be change, we should take action as far as possible in advance, because the sooner the change, the smaller loss; Second, before each design ofchanges we must analysis the quality of project and cost, and this should receive the consent of the original design. If it breakthrough the total project cost estimates after the change, this must be approved by the review of the relevant departments, we should prevent these things happened such as increasing design elements ,improving the design standards, increasing the project cost.(3) check strictly with visa procedures of the project site we should Construct project management system , establish the specialized departments,and through the use of specialized management of professionals for the project, to avoid the phenomenon that project management staff just care visa only, take no concern about the economic accounts, resulting the serious consequences such as investment is out of control.For Seriously changes of visa procedures we should make the building side, supervision side, the construction site together representatives signed a manner to ensure that the authenticity of the visa, the rationality of the economy of changes and to avoid the disputes caused by the phenomenon of fraud.(4) do a good job in the completion of the audit settlement priceClearing refers to the completion of construction enterprises in accordance with the terms of the contract completed by the contractor within the engineering, land quality experience, and in accordance with the contract, the construction units to carry out the final project settlement price. Completion of the project audited settlement is approved in accordance with the construction of the project cost. Therefore, the completion of settlement of the audit is a very important work, should focus on the following:① check the accuracy of the project quantity.the check of project Quantity is the most important and most complicated, the most detailed work in process of the settle of completed project, this must be based on completion of the project plan, changed design and construction of the scene .it strictly in accordance with the provisions of the rules one by one in terms of project review to prevent the units of construction to increase the volume of inflated project cost in the settlement on completion of the project.② examine whether the additional apply is right . check the sub-projects listed in the price in line with the fixed unit price, check whether the name, specification, measurement units and the content consistent with the units of the valuation table; for the unit price of conversion, the first step is to check if the conversion price was fixed allowed, followed check if the conversion price is correct.③ check if the standards for the admission fee In line with the cost of the fixed and the cost of policies and regulations of the project during the construction.Fifth, the thinking and outlook of project cost management system From a long time, we generally ignore the the project cost control of preparatory work for the construction phase, and control projects often focus on the cost of the construction phase - the budget review working drawings and reasonable settlement。

The Cost of Building Structure1. IntroductionThe art of architectural design was characterized as one of dealing comprehensively with a complex set of physical and nonphysical design determinants. Structural considerations were cast as important physical determinants that should be dealt with in a hierarchical fashion if they are to have a significant impact on spatial organization and environmental control design thinking.The economical aspect of building represents a nonphysical structural consideration that, in final analysis, must also be considered important. Cost considerations are in certain ways a constraint to creative design. But this need not be so. If something is known of the relationship between structural and constructive design options and their cost of implementation, it is reasonable to believe that creativity can be enhanced. This has been confirmed by the authors’observation that most enhanced. This has been confirmed by the authors’observation that most creative design innovations succeed under competitive bidding and not because of unusual owner affluence as the few publicized cases of extravagance might lead one to believe. One could even say that a designer who is truly creative will produce architectural excellence within the constraints of economy. Especially today, we find that there is a need to recognize that elegance and economy can become synonymous concepts.Therefore, in this chapter we will set forth a brief explanation of the parameters of cost analysis and the means by which designers may evaluate the overall economic implications of their structural and architectural design thinking.The cost of structure alone can be measured relative to the total cost of building construction. Or, since the total construction cost is but a part of a total project cost, one could include additional consideration for land10~20percent,finance and interest100~200 percent,taxes and maintenance costs on the order of20 percent.But a discussion of theseso-called architectural costs is beyond the scope of this book, and we will focus on the cost of construction only.On the average, purely structural costs account for about 25 percent of total construction costs, This is so because it has been traditional to discriminate between purely structural and other so-called architectural costs of construction. Thus, in tradition we find that architectural costs have been taken to be those that are not necessary for the structural strength and physical integrity of a building design.“Essential services” forms a third construction cost category and refers to the provision of mechanical and electrical equipment and other service systems. On the average, these service costs account for some 15 to 30 percent of the total construction cost, depending on the type of building. Mechanical and electrical refers to the cost of providing for air-conditioning equipment and he means on air distribution as well as other services, such as plumbing, communications, and electrical light and power.The salient point is that this breakdown of costs suggests that, up to now, an average of about 45 to 60 percent of the total cost of constructing a typical design solution could be considered as architectural. But this picture is rapidly changing. With high interest costs and a scarcity of capital, client groups are demanding leaner designs. Therefore, one may conclude that there are two approaches the designer may take towards influencing the construction cost of building.The first approach to cost efficiency is to consider that wherever architectural and structural solutions can be achieved simultaneously, a potential for economy is evident. Since current trends indicate a reluctance to allocate large portions of a construction budget to purely architectural costs, this approach seems a logical necessity. But, even where money is available, any use of structure to play a basic architectural role will allow the nonstructural budget to be applied to fulfill other architectural needs that might normally have to be applied to fulfill other architectural needs that might normally have to be cutback. The second approach achieves economy through an integration of service and structural subsystems to round out one’s effort to produce a total architectural solution to a building design problem.The final pricing of a project by the constructor or contractor usually takes a different form. The costs are broken down into 1 cost of materials brought to the site, 2cost of labor involved in every phase of the construction process, 3cost of equipment purchased or rented for the project, 4cost of management and overhead, and5 profit. The architect or engineer seldom follows such an accurate path but should perhaps keep in mind how the actual cost of a structure is finally priced and made up.Thus, the percent averages stated above are obviously crude, but they can suffice to introduce the nature of the cost picture. The following sections will discuss the range of these averages and then proceed to a discussion of square footage costs and volume-based estimates for use in rough approximation of the cost of building a structural system.2. Percentage EstimatesThe type of building project may indicate the range of percentages that can be allocated to structural and other costs. As might be expected, highly decorative or symbolic buildings would normally demand the lowest percentage of structural costs as compared to total construction cost. In this case the structural costs might drop to 10~15percent of the total building cost because more money is allocated to the so-called architectural costs. Once again this implies that the symbolic components are conceived independent of basic structural requirements. However, where structure and symbolism are more-or-less synthesized, as with a church or Cathedral, the structural system cost can be expected to be somewhat higher, say, 15and20 percent or more.At the other end of the cost scale are the very simple and nonsymbolic industrial buildings, such as warehouses and garages. In these cases, the nonstructural systems, such as interior partition walls and ceilings, as will as mechanical systems, are normally minimal, as is decoration,and therefore the structural costs can account for60 to 70 percent, even 80 percent of the total cost of construction.Buildings such as medium-rise office and apartment buildings5~10 storiesoccupy the median position on a cost scale at about 25 percent for structure. Low and short-span buildings for commerce and housing, say, of three or four stories and with spans of some 20 or 30 ft and simple erection requirements, will yield structural costs of 15~20 percent of total building cost.Special-performance buildings, such as laboratories and hospitals, represent another category. They can require long spans and a more than average portion of the total costs will be allocated to services i.e., 30~50 percent, with about 20 percent going for the purely structural costs. Tall office building 15 stories or more and/or long-span buildings say, 50 to 60 ft can require a higher percentage for structural costs about 30to 35percent of the total construction costs,with about 30 to 40 percent allocated to services.In my case, these percentages are typical and can be considered as a measure of average efficiency in design of buildings. For example, if a low, short-span and nonmonumental building were to be bid at 30 percent for the structure alone, one could assume that the structural design may be comparatively uneconomical. On the other hand, the architect should be aware of the confusing fact that economical bids depend on the practical ability of both the designer and the contractor to interpret the design and construction requirements so that a low bid will ensue. Progress in structural design is often limited more by the designer’s or contractor’slack of experience, imagination, and absence of communication than by the idea of the design. If a contractor is uncertain, he will add costs to hedge the risk he will be taking. It is for this reason that both the architect and the engineer should be well-versed in the area of construction potentials if innovative designs ate to be competitively bid. At the least the architect must be capable of working closely with imaginative structural engineers, contractors and even fabricators wherever possible even if the architecture is very ordinary.Efficiency always requires knowledge and above all imagination, and these are essential when designs are unfamiliar.The foregoing percentages can be helpful in approximating total construction costs if the assumption is made that structural design is at least of average of typical efficiency. For example, if a total office building construction cost budget is ﹩5,000,000,and 25 percent is the “standard” to be used for structure, a projected structural system should cost no more than ﹩1,250,000.If a very efficient design were realized, say, at 80 percent of what would be given by the “average”efficient design estimate stated above the savings,20 percent,would then be﹩250,000 or 5 percent of total construction costs ﹩5,000,000.If the ﹩5,000,000 figure is committed, then the savings of ﹩250,000 could be applied to expand the budget for “other” costs.All this suggests that creative integration of structural and mechanical and electrical design with the total architectural design concept can result in either a reduction in purely construction design concept can result in either a reduction in purely construction costs or more architecture for the same cost. Thus, the degree of success possible depends on knowledge, cleverness, and insightful collaboration of the designers and contractors.The above discussion is only meant to give the reader an overall perspective on total construction costs. The following sections will now furnish the means for estimating the cost of structure alone. Two alternative means will be provided for making an approximate structural cost estimate: one on a square foot of building basis, and another on volumes of structural materials used. Such costs can then be used to get a rough idea of total cost by referring to the “standards”for efficient design given above. At best, this will be a crude measure, but it is hoped that the reader will find that it makes him somewhat familiar with the type of real economic problems that responsible designers must deal with. At the least, this capability will be useful in comparing alternative systems for the purpose of determining their relative cost efficiency.3. Square-foot EstimatingAs before, it is possible to empirically determine a “standard”per-square-foot cost factor based on the average of costs for similar construction at a given place and time. more-or-less efficient designs are possible, depending on the ability of the designer and contractor to use materials and labor efficiently, and vary from the average.The range of square-foot costs for “normal” structural systems is ﹩10 to ﹩16 psf. For example, typical office buildings average between ﹩12 and ﹩16 psf, and apartment-type structures range from ﹩10 to ﹩14.In each case, the lower part of the range refers to short spans and low buildings, whereas the upper portion refers to longer spans and moderately tall buildings.Ordinary industrial structures are simple and normally produce square-foot costs ranging from ﹩10 to ﹩14,as with the more typical apartment building. Although the spans for industrial structures are generally longer than those for apartment buildings, and the loads heavier, they commonly have fewer complexities as well as fewer interior walls, partitions, ceiling requirements, and they are not tall. In other words, simplicity of design and erection can offset the additional cost for longer span lengths and heavier loads in industrial buildings.Of course there are exceptions to these averages. The limits of variation depend on a system’s complexity, span length over “normal”and special loading or foundation conditions. For example, the Crown Zellerbach high-rise bank and office building in San Francisco is an exception, since its structural costs were unusually high. However, in this case, the use of 60 ft steel spans and free-standing columns at the bottom, which carry the considerable earthquake loading, as well as the special foundation associated with the poor San Francisco soil conditions, contributed to the exceptionally high costs. The design was also unusual for its time and a decision had been made to allow higher than normal costs for all aspects of the building to achieve open spaces and for both function and symbolic reasons. Hence the proportion ofstructural to total cost probably remained similar to ordinary buildings.The effect of spans longer than normal can be further illustrated. The “usual”floor span range is as follows: for apartment buildings,16 to 25 ft; for office buildings,20 to 30 ft; for industrial buildings,25 to 30 ft loaded heavily at 200 to 300 psf; and garage-type structures span,50 to 60 ft, carrying relatively light50~75 psf loadsi.e., similar to those for apartment and office structures.where these spans are doubled, the structural costs can be expected to rise about 20 to 30 percent.To increased loading in the case of industrial buildings offers another insight into the dependency of cost estimates on “usual”standards. If the loading in an industrial building were to be increased to 500psfi.e., two or three times, the additional structural cost would be on the order of another 20 to 30 percent.The reference in the above cases is for floor systems. For roofs using efficient orthotropic flat systems, contemporary limits for economical design appear to be on the order of 150 ft, whether of steel or prestressed concrete. Although space- frames are often used for steel or prestressed concrete. Although space-frames are often used for steel spans over 150 ft the fabrication costs begin to raise considerably.At any rate, it should be recognized that very long-span subsystems are special cases and can in themselves have a great or small effect on is added, structural costs for special buildings can vary greatly from design to design. The more special the form, themore that design knowledge and creativity, as well as construction skill, will determine the potential for achieving cost efficiency.4. Volume-Based EstimatesWhen more accuracy is desired, estimates of costs can be based on the volume of materials used to do a job. At first glance it might seem that the architect would be ill equipped to estimate the volume of material required in construction with any accuracy, and much less speed. But itis possible, with a moderate learning effort, to achieve some capability for making such estimates.Volume-based estimates are given by assigning in-place value to the pounds or tons of steel, or the cubic yards of reinforced or prestressed concrete required to build a structural system. For such a preliminary estimate, one does not need to itemize detailed costs. For example, in-place concrete costs include the cost of forming, falsework, reinforcing steel, labor, and overhead. Steel includes fabrication and erection of components.Costs of structural steel as measured by weight range from ﹩0.50 to ﹩0.70 per pound in place for building construction. For low-rise buildings, one can use stock wide-flange structural members that require minimum fabrication, and the cost could be as bow as ﹩0.50 per pound. More complicated systems requiring much cutting and weldingsuch as a complicated steel truss or space-frame design can go to ﹩0.70 per pound and beyond. For standard tall building designs say, exceeding 20 stories,there would typically be about 20 to 30 pounds of steel/psf, which one should wish not to exceed. A design calling for under 20 psf would require a great deal of ingenuity and the careful integration of structural and architectural components and would be a real accomplishment.Concrete costs are volumetric and should range from an in-place low of ﹩150 per cu yd for very simple reinforced concrete work to ﹩300 per cu yd for expensive small quantity precast and prestressed work. This large range is due to the fact that the contributing variables are more complicated, depending upon the shape of the precise components, the erection problems, and the total quantity produced.Form work is generally the controlling factor for any cast-in-place concrete work. Therefore, to achieve a cost of ﹩150 per cu yd, only the simplest of systems can be used, such as flat slabs that require little cutting and much reuse of forms. Where any beams are introduced that require special forms and difficulty in placement of concrete and steelbars, the range begins at ﹩180 per cu yd and goes up to ﹩300.Since, in a developed country, high labor costs account for high forming costs, this results in pressure to use the simplest and most repetitive of systems to keep costs down. It become rewarding to consider the possibility of mass-produced precast and prestressed components, which may bring a saving in costs and\or construction completion time. The latter results in savings due to lower construction financing costs for the contractor plus quicker earnings for the owner.To summarize, the range of cost per cubic yard of standard types of poured-in-place concrete work will average from $150 to $250, the minimum being for simple reinforced work and the maximum for moderately complicated post tensioned work. This range is large and any estimate that ignores the effect of variables above will be commensurately inaccurate.5.SummaryThe estimate and economical design of structure building are important and essential work, which should be valued by all architects and engineers and others. Better you do it, more profit you will receive from it建筑结构的成本1.前言众所周知,建筑物的结构设计是一个相当复杂的过程,其中既包含处理很多物质因素,又考虑诸多非物质方面的因素.如果建筑物的结构形式对空间组织和美化环境的设计起这句举足轻重的影响,那么它就是一个相当重要的物理因素,就应当采用分阶段的设计方法.对建筑物的经济考虑是一个主要的非物质因素,在最终的设计中应予以重视.对一个具有创造性的设计而言,经济考虑从某方面来说往往是一种制约,但这也并非是绝对的.如果事先清楚结构设计及施工组织方案与实现他们的造价之间的关系,那么创造性是同样可以实现的.调查表明,大多具有创造性的设计是在有竞争性的投标中获得成功的,而不是因为业主非常富有.尽管后者被大肆炒作,却很少使人信服.因此也可以说,真正具有创造性的设计因该具有很强的经济性.特别是今天,人们应该逐渐认识到,高雅和经济其实是一个可以统一的概念.因此,本文列举一些造价分析参数的简单解释,以及设计人员在他们的结构设计中考虑经济因素是经常采用的一些设计中考虑经济因素是经常采用的一些设计手法.结构造价本身是通过其在建筑物总造价中所占的百分比来衡量的.或者说,由于工程只是一个项目总造价的一部分,因此还要考虑附加费用如地价10%~20%、筹资利息100%~200%、税金及维修费20%左右.不过上面这些因素都不在本文的讨论范围之内,文章将重点介绍工程造价.平均来说,单纯的结构造价大约占建筑物总造价25%.按照惯例,建筑无的结构造价和所谓的建筑造价是分开的.一般说来,所谓的建筑造价,往往是指那些与建筑的结构强度和物理完整性无关的因素.“基本服务设施费”组成了第三类工程费用,主要是指机械供给、电器设备以及其他一些服务体系等费用.一般说来,这部分费用大概占建筑物总费用的15%~30%,这主要取决于建筑无的类型.机械和电气费用,主要是指空调系统费用以及其他诸如管道系统、通讯、照明及动力设备等其他服务设施.在这一造价分类中非常显着的一点是,一个典型的建筑物设计方案的总体费用,应该有45%~60%分配给建筑因素.但现在这种状况正在迅速改变,因为高利率以及资金的缺乏,现在大多业主更倾向于节约型设计.因此,设计者应该考虑两条途径,他们可以直接影响建筑无的工程造价.第一个节约开支的途径可以这样来考虑,即凡是那些建筑问题和结构问题能够同时解决的地方往往有着很强的经济潜力.由于目前大多设计都不愿将建筑物费用一大部分用于纯粹建筑设计,这种方法就显得尤为重要,也会节省一部分非结构预算,这一经费可用于一些本会被削减掉的建筑需求.第二种节约开支的途径,则是设计人员在设计过程中综合考虑服务设施和结构体系,尽力提出一个能够解决房屋设计和施工难题的总建筑方案.承包商通常回用不同的方式做出工程项目的最终报价.他们往往将其分为场地材料费、每一个施工过程中的劳动力资源费、工程所需购买、租借的装备费、经营管理费以及利润.建筑师以及工程师很少考虑的像上面所述的那么精确,但是头脑中应该有一个清楚的概念,那就是一项结构工程的实际造价最终使用什么方法定价以及承包商又是怎样标价的.显然,上面讲到的百分比平均数有些粗略,但是它足以说明总体造价的组成情况了.下面的几部分将讨论这些平均数的范围,并进一步阐述在对建筑无的造价进行粗略、近似估计时用到的平方英尺以及单位体积造价.2.百分比估价建筑物的类型将决定结构费用以及其他费用所占的白分比范围.正如所希望的,装饰性或者标志性较强的建筑物的结构造价在总体造价中所占的比重相对较低.一般而言,结构造价所占的百分比可低至工程总造价的10%~15%,这是因为更多的钱被用到那些非结构费用上了.这又一次说明“装饰”部分是与基本的结构要求无关的.然而对于一些诸如教堂类的综合性标志建筑物,对其结构体系的造价相对较高,其百分比可达到15%~20%或者更高.与之相对的是一些诸如仓库或者车库之类简易的和非象征性的工业建筑物,对于这种建筑,由于内部隔墙、天花板、管道设备系统以及装修部分要求较低,其结构造价在工程总体造价中所占的比例往往能达到60%~70%,有时甚至可达80%.对于一些中等高度5~10层得多层办公楼或住宅楼,其结构造价在总体造价中所占的比例,大约维持在25%这一中间值;而对于一些低矮且跨据短的商业用房和住宅,大约3~4层高且跨度为20~30英尺以及简单的竖向要求,其结构造价将占总造价15%~20%.而一些特殊用途的建筑,如实验室和医院,则另当别论.他们需要较大的跨度以及不一般要求高的机械装备.这就导致总体造价得以大部分将被用于服务费用大约30%~50%,而单纯的结构造价约占20%.对于15层或者以上的高层办公楼以及大跨度约50~60英尺建筑物,其结构造价在总体造价中将占较高的百分比约30%~35%,而服务费用约占30%~40%.在任何情况下这些百分比数据都是具有典型性的,并可作为衡量建筑物设计平均效益的尺度.例如,如果一个较低的小跨度且不具备纪念价值的建筑物,仅仅结构造价投标就为30%的话,那么可以肯定这个结构设计是相当不经济的.另一方面,建筑师应该注意到的一个容易混淆的事实就是,经济投标往往取决于设计者和承包人的理解设计及施工要求的实际能力,能力强就能提供一个较低的投标.创造性设计受限往往是因为设计者或承包商在经验、想象力际交流方面的匮乏.如果承包者没有把握,那么它就会加大投资,以防可能遇到的意外风险.因此要使有创造性的设计在投标时具有竞争力,作为一名建筑师它应能够洞察工程潜力所在.至少建筑是应该尽可能地与想象力丰富的结构工程师、承包商甚至制造商惊醒密切配合.相反,即使对于最为普通的建筑设计,如果仅仅靠设计手册,是很难取得经济效益的.效率离不开专业知识,而最为重要的是想象力,这一点在面对一个不太熟悉的项目是尤为重要.如果建筑物结构设计至少具有中等或标准的效益时,前面所提到的百分比就对建筑物总造价估算有着很大的帮助.例如,如果一座办公楼总体造价500万美元,其中有25%时结构造价的标准,那么这一工程结构体系造价就不能超过125万美元.若设计很合理,比如时按上述的中等效益设计估算造价的80%时,那么就有25万美元,也就是5%的总体建筑费用被省下来.如果这500万资金已经到位,那么节省下的25万美元就可用于其他的经济开支.上面所有阐述表明,结构设计和建筑整体设计机械和电器的创造性结合的概念,将有助于减少单纯的结构造价,或在相同造价下提供更多的建筑费用.这样,设计成功的程度将取决于设计者的专业知识、灵活性以及设计者和承包人之间有洞察力的合作,上面讨论仅仅是提供一种建筑总体造价的全面视图,下面的部分将提供对建筑的结构造价进行估价的方法.有两种可供选择的方法将用来进行结构造价的近似估价:其一是根据单位平方英尺建筑面积,另一种则是根据所用的结构材料体积进行估价.参考上面所提到的有效设计的结构造价标准,最后的结构估价有助于对建筑的总体造价惊醒大概的了解.当然,这样得到的只是一个粗略的估价,但却会使设计负责人员对实际设计中经常要面对的经济问题有所了解.至少,这些将有助于对可供选择的结构体系的相对成本效益进行对比.3.平方英尺估算如前所述,在一个特定的时期和地区,是可以根据相似工程的平均造价,来经验地确定准平方英尺造价系数.设计者和承包人有效的利用材料和劳动力的能力不同,会导致不同平均水平的经济效率设计的.对于“标准”的结构体系而言,每平方英尺的造价为10~16美元,例如,典型的办公楼平均水平在12~16美元之间,而住宅型建筑的范围则是10~14美元.对以上两种情况,下限适用于短跨低矮的建筑,而上限则是用于较大跨度及中等高度的建筑.如同典型的住宅性建筑,普通工业建筑结构简单,通常每平方英尺的造价为10~14美元.尽管工业建筑的跨度很大,且荷载较重,但他们的布局简单,在内墙、隔墙以及天花板方面的要求较少,且一般不高.换句话说,设计和安装的简单化,可以弥补工业建筑因大跨度和重载所造成的额外造价.当然也存在着不同于平均水平的情况.变化的限度取决于体系的复杂程度、跨度超长的程度、特殊的荷载级地震条件等.例如,由于结构造价相当高,位于旧金山的Crown Zellerbach 银行和办公楼旧称得上是个例外.60英尺跨度的钢架以及底部用来承受地震荷载的自由支撑的柱子,连同旧金山糟糕的土壤状况,都造成了较高的造价.在那个时期,这样的设计是非同寻常的,正是因为其特殊的用途及标志性,它才被允许以建筑物个方面都高出同类建筑物的平均水平的造价进行建造.因此,其结构造价在总体造价中的比重接近也普通建筑物.现在将进一步叙述超长跨度的影响.正常跨度的范围规定为:住宅楼16~25英尺;办公楼20~30英尺;工业建筑为25~30英尺,且每平方英尺承重200~300磅;车库建筑为50~60英尺,且相对较轻.如果跨度增加一倍,结构造价将会提高大约20~30%.工业建筑中较大的荷载也无形中提高了建筑物的结构造价.如果一个工业建筑的荷载增加到每平方米500磅大约2~3倍的话,其结构造价也将提高20~30%.上面所述都是针对楼层系统而言的,对采用有效正交各向异性体系的公寓屋顶,不管是钢还是预应力混凝土的,其现代经济设计者的限值都是150英尺.尽管钢结构空间框架常大于150英尺,其制造费用也将大大增加.无论如何,长跨度体系都有其特殊性,它可能较多,也可能较少的影响总体建筑造价时,对于特殊的建筑物,其结构造价将随着设计的不同而明显地改变 .结构形式越特殊,由设计知识、设计的创造性以及施工技术所决定的造价节俭潜力就越大.4.体积度量估算初看起来,一个建筑师不善于精确地估计建筑过程中所用到的材料体积,并如果要得到更高的精度,可以通过工程中所用到的材料体积来估计造价.且进展会非常缓慢,但通过努力学习后,是可以实现这一估计的.体积量度估价,是通过制定结构系统中需要的以磅或吨记得钢材、立方体的钢筋或预应力混凝土的现场价格来实现的.对于这样一个初步估计,没有必要去详究它的详细造价.例如,混凝土的现浇造价将包括模板、脚手架、钢筋、劳动力等费用和间接费用.钢结构则包括构件制作及安装的费用.以重量计的建筑钢材的现场价格,从每磅0.50美元到0.70美元不等.对于低层建筑,可采用现成的宽翼缘型钢构件,只需要极少的加工,因而成本可降低至每磅0.50美元.而复杂的结构体系需要较多的切割和焊接如复杂的钢桁架或空间框架设计,因而其钢材现场价格可达0.7美元甚至更高.对于标准的高层建筑设计,每平方米大概将由20~30磅钢材,这是设计人员不希望超过的量值.而每平方米低于20磅的设计,则需要很强的创造力以及建筑物设计和结构设计上完美的结合,其可称得上是一个真正的成就.混凝土的价格是以体积计量的,其范围从简易的每立方码150美元的现浇钢筋混凝土工程,到非常昂贵的每立方码300美元的小批量所谓预制和预应力工程不等.出现如此大的价格范围.是因为影响因素较复杂,包括预制构件的形状、安装的难易其生产总量.模板通常是现场浇制混凝土构件的决定性因素,因此,为得到每立方码150美元的价格,需要采用最简单的体系方可,例如需要很少的模板加工量并可多次使用平板.一旦梁存在,就需要专门的模板,由于混凝土和钢筋的放置上的困难,价格范围每立方码180美元上升到每立方码300美元.在发达国家,由于较高的劳动力费用,导致较高的模板造价,这就迫使人们采用最简单的和大批量可重复使用的结构构件来实现造价的削减.但现场浇制价格开始接近每立方码240美元时,就应该考虑大批量生产的预制和预应力构件的使用,这样将会减少造价和缩短工期.后者将会因为时公开支费用的降低,是承包商快速赢利.总的来说,每平方码现场浇筑混凝土的标准价格将从150美元~250美元不等,其下限适用于简单混凝土工程,而上限则适用于中等复杂程度的后张预应力工程.这样一个价格范围相对较大,任何忽略了上述影响因素的估价,都将是不准确的.5.结论建筑物的成本估计及节约设计,是一项重要而又必须的工作,每一个建筑师和结构师及相关的建筑业者.都应给予充分的重视.这一工作做得越好,你得到的回报越多。

工程造价论文中英文资料对照外文翻译Risk Analysis of the International Construction ProjectABSTRACTThis analysis used a case study methodology to analyse the issues surrounding the partial collapse of the roof of a building housing the headquarters of the Standards Association of Zimbabwe (SAZ). In particular, it examined the prior roles played by the team of construction professionals. The analysis revealed that the SAZ’s traditional construction project was generally characterized by high risk. There was a clear indication of the failure of a contractor and architects in preventing and/or mitigating potential construction problems as alleged by the plaintiff. It was reasonable to conclude that between them the defects should have been detected earlier and rectified in good time before the partial roof failure. It appeared justified for the plaintiff to have brought a negligence claim against both the contractor and the architects. The risk analysis facilitated, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects. It further served to emphasize the point that clients are becoming more demanding, more discerning, and less willing to accept risk without recompense. Clients do not want surprise, and are more likely to engage in litigation when things go wrong.KEY WORDS:Arbitration, claims, construction, contracts, litigation, project and risk The structural design of the reinforced concrete elements was done by consulting engineers Knight Piesold (KP). Quantity surveying services were provided by Hawkins, Leshnick & Bath (HLB). The contract was awarded to Central African Building Corporation (CABCO) who was also responsible for the provision of a specialist roof structure using patented “gang nail” roof trusses. The building construction proceeded to completion and was handed over to the owners on Sept. 12, 1991. The SAZ took effective occupation of the headquarters building without a certificate of occupation. Also, the defects liability period was only three months .The roof structure was in place 10 years before partial failure in December 1999. The building insurance coverage did not cover enough, the City of Harare, a government municipality, issued the certificate of occupation 10 years after occupation, and after partial collapse of the roof .At first the SAZ decided to go to arbitration, but this failed to yield an immediate solution. The SAZ then decided to proceed to litigate in court and to bring a negligence claim against CABCO. The preparation for arbitration was reused for litigation. The SAZ’s quantified losses stood at approximately $ 6 million in Zimbabwe dollars (US $1.2m) .After all parties had examined the facts and evidence before them, it became clear that there was a great probability that the courts might rule that both the architects and the contractor were liable. It was at this stage that the defendants’ lawyers requested that the matter be settled out of court. The plaintiff agreed to this suggestion, with the terms of the settlement kept confidential .The aim of this critical analysis was to analyse the issues surrounding the partial collapse of the roof of the building housing the HQ of Standard Association of Zimbabwe. It examined the prior roles played by the project management function and construction professionals in preventing/mitigating potential construction problems. It further assessed the extent to which the employer/client and parties to a construction contract are able to recover damages under that contract. The main objective of this critical analysis was to identify an effective risk management strategy for future construction projects. The importance of this study is its multidimensional examination approach.Experience suggests that participants in a project are well able to identify risks based on their own experience. The adoption of a risk management approach, based solely in past experience and dependant on judgement, may work reasonably well in a stable low risk environment. It is unlikely to be effective where there is a change. This is because change requires the extrapolation of past experience, which could be misleading. All construction projects are prototypes to some extent and imply change. Change in the construction industry itself suggests that past experience is unlikely tobe sufficient on its own. A structured approach is required. Such a structure can not and must not replace the experience and expertise of the participant. Rather, it brings additional benefits that assist to clarify objectives, identify the nature of the uncertainties, introduces effective communication systems, improves decision-making, introduces effective risk control measures, protects the project objectives and provides knowledge of the risk history .Construction professionals need to know how to balance the contingencies of risk with their specific contractual, financial, operational and organizational requirements. Many construction professionals look at risks in dividually with a myopic lens and do not realize the potential impact that other associated risks may have on their business operations. Using a holistic risk management approach will enable a firm to identify all of the organization’s business risks. This wi ll increase the probability of risk mitigation, with the ultimate goal of total risk elimination .Recommended key construction and risk management strategies for future construction projects have been considered and their explanation follows. J.W. Hinchey stated that there is and can be no ‘best practice’ standard for risk allocation on a high-profile project or for that matter, any project. He said, instead, successful risk management is a mind-set and a process. According to Hinchey, the ideal mind-set is for the parties and their representatives to, first, be intentional about identifying project risks and then to proceed to develop a systematic and comprehensive process for avoiding, mitigating, managing and finally allocating, by contract, those risks in optimum ways for the particular project. This process is said to necessarily begin as a science and ends as an art .According to D. Atkinson, whether contractor, consultant or promoter, the right team needs to be assembled with the relevant multi-disciplinary experience of that particular type of project and its location. This is said to be necessary not only to allow alternative responses to be explored. But also to ensure that the right questions are asked and the major risks identified. Heads of sources of risk are said to be a convenient way of providing a structure for identifying risks to completion of a participant’s part of the project. Effective risk management is said to require amulti-disciplinary approach. Inevitably risk management requires examination of engineering, legal and insurance related solutions .It is stated that the use of analytical techniques based on a statistical approach could be of enormous use in decision making . Many of these techniques are said to be relevant to estimation of the consequences of risk events, and not how allocation of risk is to be achieved. In addition, at the present stage of the development of risk management, Atkinson states that it must be recognized that major decisions will be made that can not be based solely on mathematical analysis. The complexity of construction projects means that the project definition in terms of both physical form and organizational structure will be based on consideration of only a relatively small number of risks . This is said to then allow a general structured approach that can be applied to any construction project to increase the awareness of participants .The new, simplified Construction Design and Management Regulations (CDM Regulations) which came in to force in the UK in April 2007, revised and brought together the existing CDM 1994 and the Construction Health Safety and Welfare (CHSW) Regulations 1996, into a single regulatory package.The new CDM regulations offer an opportunity for a step change in health and safety performance and are used to reemphasize the health, safety and broader business benefits of a well-managed and co-ordinated approach to the management of health and safety in construction. I believe that the development of these skills is imperative to provide the client with the most effective services available, delivering the best value project possible.Construction Management at Risk (CM at Risk), similar to established private sector methods of construction contracting, is gaining popularity in the public sector. It is a process that allows a client to select a construction manager (CM) based on qualifications; make the CM a member of a collaborative project team; centralize responsibility for construction under a single contract; obtain a bonded guaranteed maximum price; produce a more manageable, predictable project; save time and money; and reduce risk for the client, the architect and the CM.CM at Risk, a more professional approach to construction, is taking its place along with design-build, bridging and the more traditional process of design-bid-build as an established method of project delivery.The AE can review the CM’s approach to the work, making helpful recommendations. The CM is allowed to take bids or proposals from subcontractors during completion of contract documents, prior to the guaranteed maximum price (GMP), which reduces the CM’s risk and provides useful input to design. The procedure is more methodical, manageable, predictable and less risky for all.The procurement of construction is also more business-like. Each trade contractor has a fair shot at being the low bidder without fear of bid shopping. Each must deliver the best to get the projec. Competition in the community is more equitable: all subcontractors have a fair shot at the work .A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes. As long as the subcontractors are within the GMP they are reimbursed to the CM, so the CM represents the client in negotiating inevitable changes with subcontractors.There can be similar problems where each party in a project is separately insured. For this reason a move towards project insurance is recommended. The traditional approach reinforces adversarial attitudes, and even provides incentives for people to overlook or conceal risks in an attempt to avoid or transfer responsibility.A contingency within the GMP covers unexpected but justifiable costs, and a contingency above the GMP allows for client changes.

It did appearjustified for the plaintiff to have brought a negligence claim against both the contractor and the architects.In many projects clients do not understand the importance of their role in facilitating cooperation and coordination; the design is prepared without discussion between designers, manufacturers, suppliers and contractors. This means that the designer can not take advantage of suppliers’ or contractors’ knowledge of build ability or maintenance requirements and the impact these have on sustainability, the total cost of ownership or health and safety .This risk analysis was able to facilitate, through its multi-dimensional approach to a critical examination of a construction problem, the identification of an effective risk management strategy for future construction projects.

外文文献:Project Cost Control: The Way it WorksBy R. Max WidemanIn a recent consulting assignment we realized that there was some lack of understanding of the whole system of project cost control, how it is setup and applied. So we decided to write up a description of how it works。

Project cost control is not that difficult to follow in theory.First you establish a set of reference baselines. Then, as work progresses, you monitor the work, analyze the findings, forecast the end results and compare those with the reference baselines. If the end results are not satisfactory then you make adjustments as necessary to the work in progress, and repeat the cycle at suitable intervals。

If the end results get really out of line with the baseline plan, you may have to change the plan。

More likely, there will be (or have been) scope changes that change the reference baselines which means that every time that happens you have to change the baseline plan anyway。

The Cost of Building Structure1. IntroductionThe art of architectural design was characterized as one of dealing comprehensively with a complex set of physical and nonphysical design determinants. Structural considerations were cast as important physical determinants that should be dealt with in a hierarchical fashion if they are to have a significant impact on spatial organization and environmental control design thinking.The economical aspect of building represents a nonphysical structural consideration that, in final analysis, must also be considered important. Cost considerations are in certain ways a constraint to creative design. But this need not be so. If something is known of the relationship between structural and constructive design options and their cost of implementation, it is reasonable to believe that creativity can be enhanced. This has been confirmed by the authors’ observation that most enhanced. This has been confirmed by the authors’observation that most creative design innovations succeed under competitive bidding and not because of unusual owner affluence as the few publicized cases of extravagance might lead one to believe. One could even say that a designer who is truly creative will produce architectural excellence within the constraints of economy. Especially today, we find that there is a need to recognize that elegance and economy can become synonymous concepts.Therefore, in this chapter we will set forth a brief explanation of the parameters of cost analysis and the means by which designers may evaluate the overall economic implications of their structural and architectural design thinking.The cost of structure alone can be measured relative to the total cost of building construction. Or, since the total construction cost is but a part of a total project cost, one could include additional consideration for land(10~20percent),finance and interest(100~200 percent),taxes and maintenance costs (on the order of20 percent).But a discussion of these so-called architectural costs is beyond the scope of this book, and we will focus on the cost of construction only.On the average, purely structural costs account for about 25 percent of total construction costs, This is so because it has been traditional to discriminate between purely structural and other so-called architectural costs of construction. Thus, in tradition we find that architectural costs have been taken to be those that are notnecessary for the structural strength and physical integrity of a building design.“Essential services”forms a third construction cost category and refers to the provision of mechanical and electrical equipment and other service systems. On the average, these service costs account for some 15 to 30 percent of the total construction cost, depending on the type of building. Mechanical and electrical refers to the cost of providing for air-conditioning equipment and he means on air distribution as well as other services, such as plumbing, communications, and electrical light and power.The salient point is that this breakdown of costs suggests that, up to now, an average of about 45 to 60 percent of the total cost of constructing a typical design solution could be considered as architectural. But this picture is rapidly changing. With high interest costs and a scarcity of capital, client groups are demanding leaner designs. Therefore, one may conclude that there are two approaches the designer may take towards influencing the construction cost of building.The first approach to cost efficiency is to consider that wherever architectural and structural solutions can be achieved simultaneously, a potential for economy is evident. Since current trends indicate a reluctance to allocate large portions of a construction budget to purely architectural costs, this approach seems a logical necessity. But, even where money is available, any use of structure to play a basic architectural role will allow the nonstructural budget to be applied to fulfill other architectural needs that might normally have to be applied to fulfill other architectural needs that might normally have to be cut back. The second approach achieves economy through an integration of service and structural subsystems to round out one’s effort to produce a total architectural solution to a building design problem.The final pricing of a project by the constructor or contractor usually takes a different form. The costs are broken down into (1) cost of materials brought to the site, (2)cost of labor involved in every phase of the construction process, (3)cost of equipment purchased or rented for the project, (4)cost of management and overhead, and(5) profit. The architect or engineer seldom follows such an accurate path but should perhaps keep in mind how the actual cost of a structure is finally priced and made up.Thus, the percent averages stated above are obviously crude, but they can suffice to introduce the nature of the cost picture. The following sections will discuss the range of these averages and then proceed to a discussion of square footage costs andvolume-based estimates for use in rough approximation of the cost of building a structural system.2. Percentage EstimatesThe type of building project may indicate the range of percentages that can be allocated to structural and other costs. As might be expected, highly decorative or symbolic buildings would normally demand the lowest percentage of structural costs as compared to total construction cost. In this case the structural costs might drop to 10~15percent of the total building cost because more money is allocated to the so-called architectural costs. Once again this implies that the symbolic components are conceived independent of basic structural requirements. However, where structure and symbolism are more-or-less synthesized, as with a church or Cathedral, the structural system cost can be expected to be somewhat higher, say, 15and20 percent (or more).At the other end of the cost scale are the very simple and nonsymbolic industrial buildings, such as warehouses and garages. In these cases, the nonstructural systems, such as interior partition walls and ceilings, as will as mechanical systems, are normally minimal, as is decoration, and therefore the structural costs can account for60 to 70 percent, even 80 percent of the total cost of construction.Buildings such as medium-rise office and apartment buildings(5~10 stories)occupy the median position on a cost scale at about 25 percent for structure. Low and short-span buildings for commerce and housing, say, of three or four stories and with spans of some 20 or 30 ft and simple erection requirements, will yield structural costs of 15~20 percent of total building cost.Special-performance buildings, such as laboratories and hospitals, represent another category. They can require long spans and a more than average portion of the total costs will be allocated to services (i.e., 30~50 percent), with about 20 percent going for the purely structural costs. Tall office building (15 stories or more) and/or long-span buildings (say, 50 to 60 ft) can require a higher percentage for structural costs (about 30to 35percent of the total construction costs),with about 30 to 40 percent allocated to services.In my case, these percentages are typical and can be considered as a measure of average efficiency in design of buildings. For example, if a low, short-span and nonmonumental building were to be bid at 30 percent for the structure alone, one could assume that the structural design may be comparatively uneconomical. On theother hand, the architect should be aware of the confusing fact that economical bids depend on the practical ability of both the designer and the contractor to interpret the design and construction requirements so that a low bid will ensue. Progress in structural design is often limited more by the designer’s or contractor’slack of experience, imagination, and absence of communication than by the idea of the design. If a contractor is uncertain, he will add costs to hedge the risk he will be taking. It is for this reason that both the architect and the engineer should be well-versed in the area of construction potentials if innovative designs ate to be competitively bid. At the least the architect must be capable of working closely with imaginative structural engineers, contractors and even fabricators wherever possible even if the architecture is very ordinary. Efficiency always requires knowledge and above all imagination, and these are essential when designs are unfamiliar.The foregoing percentages can be helpful in approximating total construction costs if the assumption is made that structural design is at least of average (of typical) efficiency. For example, if a total office building construction cost budget is ﹩5,000,000,and 25 percent is the “standard”to be used for structure, a projected structural system should cost no more than ﹩1,250,000.If a very efficient design were realized, say, at 80 percent of what would be given by the “average” efficient design estimate stated above the savings,(20 percent),would then be﹩250,000 or 5 percent of total construction costs ﹩5,000,000.If the ﹩5,000,000 figure is committed, then the savings of ﹩250,000 could be applied to expand the budget for “other” costs.All this suggests that creative integration of structural (and mechanical and electrical) design with the total architectural design concept can result in either a reduction in purely construction design concept can result in either a reduction in purely construction costs or more architecture for the same cost. Thus, the degree of success possible depends on knowledge, cleverness, and insightful collaboration of the designers and contractors.The above discussion is only meant to give the reader an overall perspective on total construction costs. The following sections will now furnish the means for estimating the cost of structure alone. Two alternative means will be provided for making an approximate structural cost estimate: one on a square foot of building basis, and another on volumes of structural materials used. Such costs can then be used to get a rough idea of total cost by referring to the “standards” for efficient design givenabove. At best, this will be a crude measure, but it is hoped that the reader will find that it makes him somewhat familiar with the type of real economic problems that responsible designers must deal with. At the least, this capability will be useful in comparing alternative systems for the purpose of determining their relative cost efficiency.3. Square-foot EstimatingAs before, it is possible to empirically determine a “standard” per-square-foot cost factor based on the average of costs for similar construction at a given place and time. more-or-less efficient designs are possible, depending on the ability of the designer and contractor to use materials and labor efficiently, and vary from the average.The range of square-foot costs for “normal” structural systems is ﹩10 to ﹩16 psf. For example, typical office buildings average between ﹩12 and ﹩16 psf, and apartment-type structures range from ﹩10 to ﹩14.In each case, the lower part of the range refers to short spans and low buildings, whereas the upper portion refers to longer spans and moderately tall buildings.Ordinary industrial structures are simple and normally produce square-foot costs ranging from ﹩10 to ﹩14,as with the more typical apartment building. Although the spans for industrial structures are generally longer than those for apartment buildings, and the loads heavier, they commonly have fewer complexities as well as fewer interior walls, partitions, ceiling requirements, and they are not tall. In other words, simplicity of design and erection can offset the additional cost for longer span lengths and heavier loads in industrial buildings.Of course there are exceptions to these averages. The limits of variation depend on a system’s complexity, span length over “normal” and special loading or foundation conditions. For example, the Crown Zellerbach high-rise bank and office building in San Francisco is an exception, since its structural costs were unusually high. However, in this case, the use of 60 ft steel spans and free-standing columns at the bottom, which carry the considerable earthquake loading, as well as the special foundation associated with the poor San Francisco soil conditions, contributed to the exceptionally high costs. The design was also unusual for its time and a decision had been made to allow higher than normal costs for all aspects of the building to achieve open spaces and for both function and symbolic reasons. Hence the proportion of structural to total cost probably remained similar to ordinary buildings.The effect of spans longer than normal can be further illustrated. The “usual” floorspan range is as follows: for apartment buildings,16 to 25 ft; for office buildings,20 to 30 ft; for industrial buildings,25 to 30 ft loaded heavily at 200 to 300 psf; and garage-type structures span,50 to 60 ft, carrying relatively light(50~75 psf) loads(i.e., similar to those for apartment and office structures).where these spans are doubled, the structural costs can be expected to rise about 20 to 30 percent.To increased loading in the case of industrial buildings offers another insight into the dependency of cost estimates on “usual” standards. If the loading in an industrial building were to be increased to 500psf(i.e., two or three times), the additional structural cost would be on the order of another 20 to 30 percent.The reference in the above cases is for floor systems. For roofs using efficient orthotropic (flat) systems, contemporary limits for economical design appear to be on the order of 150 ft, whether of steel or prestressed concrete. Although space- frames are often used for steel or prestressed concrete. Although space-frames are often used for steel spans over 150 ft the fabrication costs begin to raise considerably.At any rate, it should be recognized that very long-span subsystems are special cases and can in themselves have a great or small effect on is added, structural costs for special buildings can vary greatly from design to design. The more special the form, themore that design knowledge and creativity, as well as construction skill, will determine the potential for achieving cost efficiency.4. Volume-Based EstimatesWhen more accuracy is desired, estimates of costs can be based on the volume of materials used to do a job. At first glance it might seem that the architect would be ill equipped to estimate the volume of material required in construction with any accuracy,and much less speed.But it is possible,with a moderate learning effort,to achieve some capability for making such estimates.V olume-based estimates are given by assigning in-place value to the pounds or tons of steel, or the cubic yards of reinforced or prestressed concrete required to build a structural system. For such a preliminary estimate, one does not need to itemize detailed costs. For example, in-place concrete costs include the cost of forming, falsework, reinforcing steel, labor, and overhead. Steel includes fabrication and erection of components.Costs of structural steel as measured by weight range from ﹩0.50 to ﹩0.70 per pound in place for building construction. For low-rise buildings, one can use stock wide-flange structural members that require minimum fabrication, and the cost couldbe as bow as ﹩0.50 per pound. More complicated systems requiring much cutting and welding(such as a complicated steel truss or space-frame design) can go to ﹩0.70 per pound and beyond. For standard tall building designs (say, exceeding 20 stories),there would typically be about 20 to 30 pounds of steel/psf, which one should wish not to exceed. A design calling for under 20 psf would require a great deal of ingenuity and the careful integration of structural and architectural components and would be a real accomplishment.Concrete costs are volumetric and should range from an in-place low of ﹩150 per cu yd for very simple reinforced concrete work to ﹩300 per cu yd for expensive small quantity precast and prestressed work. This large range is due to the fact that the contributing variables are more complicated, depending upon the shape of the precise components, the erection problems, and the total quantity produced.Form work is generally the controlling factor for any cast-in-place concrete work. Therefore, to achieve a cost of ﹩150 per cu yd, only the simplest of systems can be used, such as flat slabs that require little cutting and much reuse of forms. Where any beams are introduced that require special forms and difficulty in placement of concrete and steel bars, the range begins at ﹩180 per cu yd and goes up to ﹩300.Since, in a developed country, high labor costs account for high forming costs, this results in pressure to use the simplest and most repetitive of systems to keep costs down. It become rewarding to consider the possibility of mass-produced precast and prestressed components, which may bring a saving in costs and\or construction completion time. The latter results in savings due to lower construction financing costs for the contractor plus quicker earnings for the owner.To summarize, the range of cost per cubic yard of standard types of poured-in-place concrete work will average from $150 to $250, the minimum being for simple reinforced work and the maximum for moderately complicated post tensioned work. This range is large and any estimate that ignores the effect of variables above will be commensurately inaccurate.5.SummaryThe estimate and economical design of structure building are important and essential work, which should be valued by all architects and engineers and others. Better you do it, more profit you will receive from it!建筑结构的成本1.前言众所周知,建筑物的结构设计是一个相当复杂的过程,其中既包含处理很多物质因素,又考虑诸多非物质方面的因素。

Described the current stage of the project cost management situation on the strengthening of the various stages of construction cost management of the importance of and raised a number of key initiatives.Keywords:cost of the construction project cost management status investment decision phase of the design phase of the implementation phase of the cost management in a market economy,Even under the WTO and China's accession to the world community, China's construction industry how to effectively control construction cost of the construction and management of an important component part. However, the current budget for the construction projects - estimate, budget, Super budget accounts for the "super three" is still widespread and that eventually led to a serious loss of control of project investment. Project cost management is the basic contents to determine reasonable and effective control of the project cost.As the project cost to the project runs through the entire process, stage by stage can be divided into Investment Decision stage, the design and implementation phases. The so-called Project Cost effective control is the optimization of the construction plans and design programs on the basis of in the building process at all stages, use ofcertain methods and measures to reduce the cost of the projects have a reasonable control on the scope and cost of the approved limits.Engineering and cost management work of the current status of project cost management system was formed in the 1950s, 1980s perfect together.

However, as the socialist market economic development, the system's many problems have also exposed. Generally speaking, the budget estimate is based on direct participation in the management of national economic activity as a precondition. enterprise is not the actual economic entities. Due to the characteristics of the planned economy, and, at the time under the conditions of productivity, will inevitably become a shortage in the economy.In severe shortage of commodities under the conditions, as long as a certain level of investment, will be certain outputs. In this environment, the project planning and technical argumentation there can be no economic analysis. State control of the project cost constitute key factors equipment and materials prices, wages and taxes of artificial distribution. In this relatively stable economic environment, the budget estimate for the system approved project cost, help the government to carry out investment plans to play a major role.As the socialist market economic system established, requires us to predict project investment and control. In recent years, international investment project developed to the requirements of prior pre-control and in the middle of control. China,the traditional practice in an objective light on the cause decision-making, implementation heavy, light the economy and technology,First, the consequences of victimization,Due to the technical personnel of the project technical and economic concepts and a weak awareness of cost control, cost management makes the quality difficult to raise. Project Cost control is difficult to achieve long-term goals.Second, the various stages of the project management view of the above circumstances, My first academia in the 1980s made the whole process of cost management and control concept, building departments will study the feasibility of projects and the budgets and final accounts to two extended at the request of the corresponding regulations put our cost management concepts and methods referred to a new height.Our task now is to be modern and cost management in line with China's national conditions of the market economy system goal, learn from the advanced experience of the developed countries, and establish sound market economic laws of project cost management system, efforts to increase the project cost levels. An investment decision-making phase of the project cost management construction project investment decision-making stage is proposed project proposals; conduct a feasibility study to determine investment estimation and the final preparation of design task. At this stage, the project's technical and economic decision-making, of the construction project cost of the project after the completion of the economic benefits have a decisive influence, The construction cost is an important stage control.China's current stage of the project cost for the project management for the purpose of clearing price, and focusing only on the construction process of cost control, neglected before the start of the project investment decision-making stage of cost control. Investment decision-making phase of investment projects is estimated an important basis for decision-making. It has a direct impact on national economic andfinancial analysis of the results of the reliability and accuracy. Because of this phase is the preliminary work of projects, the information can not be fully, comparable works more or less that information accumulated relatively small, estimated inadequate and unscientific. Makes project cost management and cost workers is difficult at this stage do something.The various stages of the project cost control in the decision-making phase project cost control. Right project planning phase of the cost, many owners have the wrong understanding that the lower the cost the better. Cost control is not a unilateral issue, and should be a number of factors, a combination of practical, comprehensive consideration. The construction project investment decision-making stage, the project's technical and economic decision-making, Cost of the project after the completion of the project and the economic benefits, with a decisive role in project cost control is an important stage, rationally define and control the direction of the project cost of accurate positioning and building Optimization guiding role.In the decision-making phase of the most important is to do a good job feasibility study, the work is done well, returns on investment and can form a good proportion. Otherwise, invest more, less effective, resulting in loss of control and waste of investment.At present, some of the projects planned the owners of departure from the subjective desires of a feasibility study on the lack of scientific proof. Feasibility Study untrue, false or engineering functions obtaining the approval of their superiors, actually put into the feasibility study will be awarded in the study for the project after the smooth functioning buried a lot of hidden problems, lead to insufficient follow-up funds for the project and had to extend the time limit so that the project could not have planned the use of cost-effective, even become hopeless completion of the beard works.Therefore, in order to phase in the investment decision-making effectively control construction costs, we must do the following aspects:ⅰImplementation of the construction project and corporate accountability, Construction of the project from planning to implementation of the entire process and the use of the funds to repay responsibilities to the people. in addition to establishing a legal system and the project supervision matching mechanism by the departments in charge of the industry and supervision departments for setting up a monitoring group to oversee the use of funds.ⅱA realistic approach to market analysis, to avoid the blindness of the project decision-making, reduces and reduces investment risk. Fully consider building projects in the future market competitiveness, design task more scientific and reliability.ⅲCapital financing must have a formal commitment document, the parties must do investment funds in place, and funds must have documents to ensure that the project can be approved after the scheduled implementation. To the various loan conditions should be carefully analyzed to minimize the burden of interest and repayment pressure.ⅳTo strengthen the engineering geology, hydrology, geology and land, water, electricity, transport, environmental projects such as external conditions for the work of depth to make the investment estimate there are sufficient grounds.Taking extensive investigation and research, comparison of similar projects, seriously functional analysis, multi-program comparison and choice. After full technical appraisal and economic evaluation, and the final technologically advanced, functional and reliable. Reasonable economic projects, thus calculate a more accurate and realistic estimation of the amount of investment, so that the project cost from the start positioning in a more reasonable level.The design phase of the project cost control for a long time, China's building control very effective, - investment projects is not uncommon, this will affect owners of investment returns, it adds to the owners and within budget, as well as difficulties in fund owners, the impact on the future management or the owners make payments in arrears, and so on. Hence, the control of the project cost is of great significance, however the project cost is the primary means of control design,Currently most of the property owners in the design stage seldom works on cost control, and they found that the cost of the design will not have a great impact, it is wrong, on the contrary, Design phase of the project cost control is the most important step. Because it determines engineering design, construction methods, materials and equipment types, models of the project cost is of critical significance, design optimization phase of the program or minor changes, project cost will have a significant impact, Design phase of the project cost control of the total project cost of 70%. Following is how to control the project from design to create the Law: ⅰAs the owners must design, the design selected on the quality level is a direct impact on the quality of product design level, and the design quality products in the level of direct influence on the pricing of the works. Different design units on the same project design are different. the same item of different design institute works between certain aspects of the project cost on the existence of differences between, We assume that with a design from two different design institute to design, Construction plans after the completion of a requested advisory unit cost to do the budget, certainly different design institute the total cost of the project is absolutely not the same, and most of the difference between the two over 10% even more than 30%, and not necessarily high cost than the design of low cost, and good design is often low cost, We all know that different people have different design styles and different levels, the design works naturally, therefore chosen to design units is the control on the first step. Through tender to select the design of the units is a goodmethod, the tender documents to elaborate on this particular aspect of the requirements, cost control targets, and so on.Otherwise, in the subsequent design process design units will put an increase in the cost of the design requirements; through tendering the project design into the market, compared to select the best design units.ⅱPromoting the design bidding and design optimization campaign mode design units assessed by experts using scientific group France, in accordance with applicable, economic, aesthetic principles and advanced technology, reasonable structure to meet building energy efficiency and environmental requirements, comprehensive assessment of the merits of the program design, selection of the best determination of the successful program.Successful investment program estimated to be close to the general construction project scope of investment. This means two design contracts will help design the program of choice and competition to ensure that the selected design advanced technology, unique novelty, adaptability, as well as to control the cost of the project. Design units should strive to improve their quality of the project design clever idea, contemporary reducing the project cost on to rack their brains to improve design quality, strive to put the design phase of the project cost control approval of the investment ceiling.ⅲStrengthening the design stage of the design phase to strengthen supervision of the Commissioner to determine a reasonable design, mature technology, reduction in the construction phase major design changes and changes in the program, in the effective control of the project cost will play a role. 1 to the design of the project if the project supervision to get involved, excluding unfavorable factors may generally is excluded from the 80% errors. In the entire process of building cost control, construction began at best to save and invest 20%, the key lies in the construction phase of the identification and control costs. Supervision of the design phase include :Design Institute under the design drawings and notes help owners deal with different design options for the economy, capital expenditure to develop the preliminary estimates, to ensure that the investment can be most effectively utilized. With the owners of the Commissioner include:According to the Design Institute to provide design drawings and notes to help owners deal with different design options for the economy, capital expenditures to develop the preliminary plan to ensure that investment can be most effectively used; with the owners of different design options, the need to calculate their own materials and equipment to conduct a cost analysis and study, to the design staff costs, to assist them in the investment limit within limits designed to save and invest. To seek a one-time small investment and economic good design program made the most rational economic indicators.ⅳDesign actively promote the so-called cap limit design, even with the approval of the design task and investment estimates, guarantee the functional requirements of the premise. The preliminary design and control budget, according to the preliminary approval of the total budget for the design and construction design control. Limits, and every one professional, each of whom have a design threshold of a target. In the design process, designers should progress to more programs, design optimization, ensuring that the design is technically advanced and reasonable, innovative, stylish, and do not break the limit investment objectives, thus eliminating the engineering design raise the factor of safety and design standards, or only consider the technical feasibility of the program, rather than economic rationality phenomenon, the project cost to ensure effective control.Also known as the value of value engineering analysis, is a modern scientific management technique, is a new techno-economic analysis, is the product of functional analysis to conserve resources and reduce the cost of the purpose of an effective method. It made up for the traditional cost management simply focus oncost reduction and quality management only emphasizes improving the quality deficiencies, construction is conducive to resolving the long-standing long period, a lot of wastage, poor quality, high-cost problems. Value Engineering laws generally divided into three steps: assessment of the design of object technology and economic Score; Calculation of the target group of technical and economic indicators; calculate the geometric design of the object, on average; from comparison choose the best design.Construction phase of the project implementation unit construction cost management to control the cost of the project is reasonable in the project to meet quality standards premise, in the investment decision-making stage, the design phase and construction phase of the project put the project approval occurred in the control limits, strive in various construction projects rational use of human, material and financial resources to achieve good investment returns and social benefits.The project cost control and management is a dynamic process. The dynamic market economy, to make the investment in the identification and control become more complex, this will require the construction units to the management of project cost to the project runs through the entire process, it is necessary to have a comprehensive focus. The implementation phase of the projects. The implementation phase of the project cost management is the implementation of the entire process of project management. Project implementation phase of the project cost management can be divided into three parts: the tender management, construction management and settlement management.Bidding for the construction phase of the construction units Bidding system control engineering cost effective means, bid organization can improve thecost-effectiveness of construction projects and ensure the quality of construction projects, shortening the construction cycle return on the investment, construction units can take full advantage of bidding for the effective means of cost control.Construction No. 10 on the 7th ministerial decree issued a "contract with the Construction Contract Pricing Management." clearly pointed out in bidding for projects using inventories. This requires the building of units conducting the tender exercise, in the tender document to include not only the usual content, like tender notes before schedule, tender notes, the conditions of the contract, the contract terms of the agreement, contract format, technical specifications, drawings, tender documents and other reference format, it is also necessary to provide the engineering inventory, Bidding as a reference document of the important components.Construction units in the tender document for the project inventory, in accordance with state or local rules promulgated by the calculation that the reunification of the divided projects, unified measurement units and the reunification of the engineering calculation rules, according to design drawings to be calculated and statistical arranged, obtain the list. Quantities to be followed in the preparation of an objective, impartial, scientific, and rational principle. Compilers must have strong manly budget, and should have certain knowledge of the engineering design and construction experience, and the material and mechanical construction technology for comprehensive scientific knowledge, in order to calculate the volume of the works without heavy missed. The basis of which must be in accordance with state regulations engineering calculation rules, and the sub-projects division engineering units, and in accordance with design drawings, design essential Love tender documentation requirements are calculated.Quantities of the project should have a testing general, the entries must be simple, while not appear Lousing wrong items Pricing should guarantee the correctness of the project. Should the requirements of the different grades separate engineering division, the situation was different; we may have different prices for the items separately. This requires the preparation of the list compilers, seriously study design drawings, Analysis of the tender documents include the elements of the workand the different technical requirements, all familiar with the process, and to the scene of serious investigation, is forecast to make possible the construction of the case, right will have an impact on the Price of projects to be broken down. In addition, because the project inventories to calculate the amount of the project is not complete engineering and consider the interests of the construction units, clearly paying the price for the same overall price, the quantity list by the number of actual construction is a practical terms.In the evaluation and review of the tender offer should do the units total individual Price quotations and the comprehensive assessment. Price does not meet the requirements of individual shows Price meets the requirements, and the lowest total Price could not explain the single lowest bidder. Bidders often know the total cost to maintain the same circumstances; the project is likely to change smaller projects to lower the price.Changes may be larger projects price increases to achieve the completion of clearing works will be added for the purpose. We would also do price and the corresponding quantity of comprehensive engineering assessment of the large volume of projects to focus on the price analysis. Price will do with the contents of the work, construction program, a comprehensive technical evaluation process, thereby preferred choice of a construction unit. Construction of the construction phase of the contract cost control basis. Signed tight construction contract, while strengthening the construction contract management can guarantee that the contract price is reasonable, legitimacy and reduce the performance of the contract A, B in disputes and safeguard the interests of both the contract, effective control of the works investment costs.After the signing of the contract, to do the management contract documentation, contract and the supplementary contract agreement until the regular meeting site in minutes. Work contacts such as a single content of a contract extension and explained that the integrity must be preserved, in addition to establishing a technical files,Implementation of the contract for dynamic analysis, results of the analysis to take proactive measures.Construction phase in the construction phase construction plan is based on the budget or Ken works contract price of the target, Ken control the cost of the project. At this stage of conservation has room for a small, but the possibility of waste is great. Thereby to control the cost of the project to give sufficient attention.ⅰConstruction program to strengthen the comparative technical and economic construction program is construction design of a re - to the contents of the work, a reasonable construction plan, shorten the construction period and ensure the qualityof the project, improving economic efficiency, Construction of the program right from the technical and economic evaluation were compared, through qualitative and quantitative analysis, the quality, time, Cost three technical and economic indicators, be rational, and effective use of manpower, material and financial resources, achieve better economic efficiency, good construction management relations, a comprehensive cost management is an important way.ⅱStrictly related changes to the project budget control in the proposed budget. Construction of the changes caused by many reasons, including works poorly designed, so that the engineering contract with the drawings provided inconsistent; the current market supply of materials do not meet the standard specifications of the design requirements. These issues have to leave breadwinner project cost factors. Therefore, in the construction process, we must tighten customs change, through no design changes to expand the scale and improve the design standards; increase the construction and contents, the best implementation of the "grade control, visa quota" system. Right to change the design, particularly as it relates to the cost of the design changes must be approved by the design units, construction units scene representatives, supervision engineers common signature, and should be ahead of this type of change, reduce losses, because it has been completed or partially completedproject will entail the demolition of the contents, it is bound to cause major changes to the loss. Therefore, the construction units should be assigned to the project cost management professionals Permanent construction site, to grasp at any time. Control project cost of the changes.ⅲWorks on the scene visa formalities through strict control of the construction project supervision system, the establishment of specialized departments, Professional use of the professional management of projects and to avoid project management personnel just visas, not economic account of the phenomenon. Investment out of control caused serious consequences. To serious change visa procedures to be taken to the building, Supervisor, the construction site together representatives signed the way to ensure that change, visa authenticity, legitimacy, economic and avoid fraud and the resulting phenomena arising from the dispute.In the course of construction, the construction units to enhance on-site construction management, supervision and construction side according to the drawings, and strictly control the change of the negotiations, materials substitution, the scene visas, and various additional extra budgetary labor costs for the necessary changes should be done first afterwards, after money, Change event on the timely change in the calculation of the workload and the cost of change occurred to grasp at any time cost of the project level, things to avoid a backlog of work that the true cost of the project.Construction unit representatives to the scene to supervise doing a good job record, particularly concealed records and visas, reduce clearing the passing phenomenon. Many works visa scene is not as serious, works to bring a very large settlement of the trouble, lead to considerable economic losses, the scene strict visa management of the construction phase of the project cost control key.ⅳOf project list rigorous review of the project on the review of inventories, Engineers’ monitor list of measures to control the project. BOQ to provide the list ofmeasures is to complete construction projects, occurred in the pre-construction engineering and construction process technology, life and safety aspects ofnon-engineering projects entities. At this stage because many projects are in construction plans and the construction site of the imperfections on the tender wait until the construction tender of the project design and actual scene have better access. Management Engineer addresses the gathering first-hand information on the original, itemized checking identification, inconsistent make revisions.ⅴControl material consumption, rationally define material prices. Cost of the project control materials price control is the main, the cost of materials in engineering often holds substantial proportion, usually accounts for the estimated costs of 70%, representing the direct costs of 80%. It is necessary in the construction phase in strict accordance with the contract amount of material control; material set reasonable prices, so as to effectively control the cost of the project. Market economy material supply a variety of channels, variety and price range materials, construction unit budget management and field personnel should pay close attention to market rates, with the progress of the scene, the market, hand in the construction of the information and materials for the completion of the accounts provide a strong basis.ⅵTechnology and economic integration, strengthening investment control. Effective control of the investment, from organizational, technical, economic, contracts, and other measures. Therefore, the construction units must strengthen management, engineering and technical personnel of the "economy" concept, the quality of education, Training pragmatic working style, the construction side to help improve construction design, reasonable security, financial, and material resources. Accelerate the pace of work to improve the quality of the projects. Construction should encounter problems in a timely manner with the designer linked to choose both economic and scientific potential solutions, overcome the waste caused by command, to give due attention to the importance of investment in conservation, is。

工程造价管理前沿摘要:工程造价管理的基本内容,确定合理和有效控制工程造价。

描述现阶段的工程造价管理的情况,加强了各阶段的工程造价管理工作的重要性,并提出了若干关键性举措。

关键词:建设成本;建设工程造价管理的地位;市场经济条件下管理投资的决策阶段;设计阶段;实施阶段;1前言即使在世贸组织和中国加入世界大家庭, 是中国建筑业如何有效地控制工程造价的建设和管理的一个重要组成部分。

然而,目前的年度预算为建设项目-概算,预算,超预算的"三超"现象仍然普遍存在,最终导致了严重失控项目投资。

工程造价管理的基本内容,就是合理确定和有效控制工程造价。

作为这项工程的费用,以项目贯穿整个过程中, 按阶段可分为:投资决策阶段,设计和实施阶段。

所谓工程造价的有效控制, 在优化建设方案,设计方案的基础上,在建设过程的所有阶段使用某些方法和措施,以降低工程成本有一个合理控制的范围和成本的核定限额。

2 工程造价管理工作的现状工程造价管理制度形成于50年代, 80年代成熟起来,表现为国家直接参与管理经济活动。

规定在设计阶段,以不同的概算或预算的编制以及政府,没有有关部门制订财政预算案、内容、方法和审批, 这份预算案将提供固定费用、设备和材料,采用固定价格的预算编制、审批、管理权限,等等。

随着历史进程经过恢复、改革和发展,形成了比较完备的概预算定额管理制度。

但是,随着社会主义市场经济的发展,制度的许多问题也暴露出来。

一般来说,预算是基于直接参与管理国家的经济活动作为先决条件,企业并不是实际的经济实体,由于特征的计划经济体制,并在当时的条件下,生产力必将成为短缺经济。

严重的商品短缺的情况下,只要有一定程度的投资将产品产出。

在这种环境下,项目的规划和技术论证就不可能有经济分析。

国家控制的项目成本构成要素的设备和材料价格。

在这种相对稳定的经济环境,财政预算的制度,核定工程造价, 帮助政府进行投资计划方面发挥了重大作用。

随着社会主义市场经济体制的确立,要求我们以预测项目的投资和控制。

近年来,国际投资项目的发展要求,事前预控,事中控制。

中国传统的做法,从客观的角度对事业的决策,执行重,轻经济。

首先,由于技术人员的工程技术和经济观念和意识淡薄成本控制,成本管理,使质量难以提高。

工程造价控制是很难达到的长远目标。

第二,各个阶段的项目管理鉴于上述情况,我国在八十年代提出了全过程的成本管理与控制的概念,建设部门将进行可行性研究和项目的预算和决算等,以扩大两国的请求的相应规定,我们把成本管理的观念和方法提到了一个新高度。

我们现在的任务是要与现代成本管理的,符合中国国情的市场经济的系统目标,借鉴先进发达国家的经验, 建立健全市场经济规律的工程造价管理体系,努力提高工程造价的水平。

投资决策阶段的工程造价管理建设项目投资决策阶段是提出项目建议书,进行了可行性研究,确定投资估算,最终编制设计任务。

在这个阶段,项目的技术和经济决策, 对建设项目工程造价的工程完成后的经济效益有着决定性的影响,建造成本是一个重要的阶段控制。

我国现阶段的工程造价进行的项目管理的目的是出清价,只注重施工过程的成本控制, 忽略开始的项目投资决策阶段的成本控制。

投资决策阶段的投资项目,估计是一个重要的决策依据。

它直接影响到国民经济及财务分析结果的可靠性和准确性。

因为这个阶段是工程的前期工作,信息不能完全, 同类作品或多或少地积累的资料比较少,估计不够全面,不科学。

使工程造价管理和成本工人现阶段很难有所作为。

各个阶段的工程造价控制在决策阶段的工程造价控制。

权项目规划阶段的成本,许多业主有错误的理解,降低成本,更好。

控制成本,而不是单方面问题,而应该是一个多因素的影响,结合实际,全面考虑。

建设项目的投资决策阶段,项目的技术和经济决策,工程造价后,工程的竣工和经济效益,有决定性作用,在项目成本控制是一个重要的阶段,合理确定和控制方向的工程造价准确定位和建立优化的指导作用。

在决策阶段最重要的是做好可行性研究。

这项工作做得好,投资回报率,能够形成一个良好的比例。

否则,投资多,收效不大,导致失控和浪费投资。

目前,一些项目的策划,从主观愿望的可行性研究缺乏科学论证。

可行性研究报告不真实,虚假或工程职能须经实际付诸可行性研究会在批出的研究项目后,顺利消除不少隐患, 结果导致没有足够的后续资金支持项目,并延长时限,使该项目没有计划的使用效益,甚至成为竣工无望的工程。

因此,以期在投资决策中有效地控制工程造价,必须做好以下几方面的工作:1)实施建设项目法人责任制三峡工程从规划到执行的整个过程和使用的资金偿还责任落实到人。

除了要确立的法律制度和工程监理配套机制,由主管部门的工商及监管部门成立监察小组,负责监督资金的使用。

2)实事求是的态度,市场分析,以避免盲目性,对项目决策,减少和降低投资风险。

充分考虑建设项目在未来的市场竞争力,设计任务的科学性和可靠性。

3)资金必须有正式的承诺文件,各方必须做投资资金到位, 基金必须有文件,以确保可以批准立项后,原定执行。

对各项贷款的条件应仔细分析,以减少利息负担和还款压力。

4)加强工程地质、水文地质、土地、水、电力、交通、环保工程等外部条件的工作深度,使投资估算有充分的理由。

同时广泛调查研究,比较同类项目,认真进行功能分析,多方案比较和选择。

经过充分的技术论证和经济评价,最后以技术先进,实用可靠。

经济合理的项目,从而计算出一个更准确,实事求是地估计投资额,使工程造价从一开始就定位在一个较为合理的水平。

3设计阶段的工程造价控制长期以来,我国建筑控制很有效,因此,控制工程造价具有重要意义, 但工程造价的主要方法是控制设计。

目前大部分的业主在设计阶段很少工程的成本控制,而他们认为成本的设计不会有太大的影响,这是不对的,相反的,设计阶段的工程造价控制是最重要的一步。

因为它决定了工程设计、施工方法、材料和设备的种类,优化设计阶段的程序或小的变化, 工程造价将会产生重大影响,设计阶段的工程造价控制项目总成本的70% 。

以下是如何控制工程从设计到管理。

3.1作为业主,必须重视设计设计选定的质量水平直接影响产品质量的设计水平, 而设计产品质量的水平,直接影响定价的工程量。

不同的设计单位对同一项目的设计是不同的。

同一项目的不同设计研究院工程之间某些方面的工程造价就存在分歧之间,我们假设设计由两个不同的设计院设计, 施工图完成后,所要求的咨询单位成本做预算。

当然不同设计院的项目的总成本是绝对不一样的, 大部分两者的差异超过10% ,甚至超过30% , 而不一定是成本高,比设计成本低,良好的设计往往是成本低,我们都知道,每个人有不同的设计风格,不同层次的设计作品自然因此选择设计单位,是管制的第一步。

通过招标选择设计单位,是一个很好的方法,在招标文件中详细说明这方面的要求,成本控制目标等等。

否则,在以后的设计过程中设计单位会提出增加成本的设计要求;通过招标项目的设计进入市场,为选择最好的设计单位。

3.2 提倡设计招投标和设计优化战役模式设计单位评估由专家组成, 按照适用,经济,美学原理和先进技术, 结构合理,以满足建筑节能和环保的要求,综合评价的优点,规划设计, 择优确定中选方案。

成功的投资计划估计将接近一般建设工程范围内的投资。

这意味着两个设计合约,将帮助设计方案的选择和竞争机会,以确保获选设计先进的技术,独特的新颖性,适应性,以及控制工程造价。

设计单位要努力提高自身素质,该项目设计巧妙构思, 当代降低工程成本上动脑筋,以提高设计质量, 力争把设计阶段的工程造价控制批准的投资上限。

3.3 加强设计阶段以加强监督专员,以确定一个合理的设计, 成熟的技术,减少在施工阶段主要设计变化和在节目中, 在有效控制了工程造价将扮演一个角色。

工程的设计,如果工程监理介入排除不利因素,一般可排除80%的错误。

在整个建设过程中的成本控制,在开始施工时尽量节约投资20%,关键施工阶段的识别和控制成本。

监督的设计阶段,包括: 设计院的设计图纸和说明,协助业主处理不同设计方案的经济, 资本开支与发展的初步估计,以确保投资能够得到最有效的利用。

与业主,监理,包括:根据设计院提供的设计图纸和说明,协助业主处理不同的设计方案经济,资本支出发展的初步规划,以确保投资能够得到最有效的利用;与业主不同的设计方案, 需要计算自己的材料和设备进行成本分析和研究, 对设计人员的费用,以协助他们在投资限额范围内设计,以节省投资。

寻求一次性投资少,经济好的设计方案,取得最合理的经济指标。

3.4积极推动所谓的上限限额设计即使批准的设计任务书和投资估算,在保证功能要求的前提下。

初步设计和概算控制, 据初步批准的预算总额为设计和施工图设计控制。

而每一个专业,每一个都有一个门槛设计的一个目标。

在设计过程中,设计师要进步多方案,优化设计, 确保设计在技术上是先进,合理,创新,时尚,而不是打破限制投资的目标, 从而杜绝了工程设计,提高安全系数和设计标准, 或只考虑技术可行性的计划,而非经济理性的现象, 这项工程的费用,以确保有效控制。

又称价值工程的价值分析,是一种现代科学管理技术, 是一个新的技术经济分析的是产品的功能分析,以节约资源,降低成本的目的,一个有效的方法。

它弥补了传统的成本管理单纯强调降低成本和质量管理只强调改善质量缺陷,建设,有利于解决长期存在的时间长,浪费大,质量差,成本高的问题。

价值工程法一般分为三个步骤:评估的面向对象技术和经济评分评分;计算对象的技术和经济指标; 计算几何设计的物体,平均从比较中选择最佳的设计。

4 建设项目实施阶段的单位工程造价管理控制工程成本,是合理的该项目达到质量标准的前提下,在投资决策阶段, 设计及建造阶段的项目,把项目审批出现在管制范围内,力争在各项建设工程合理使用人力, 物力和财力资源,以取得良好的投资效益和社会效益。

项目成本控制和管理是一个动态的过程。

动态的市场经济,使投资在确定与控制变得更为复杂,这将要求施工单位对工程造价管理的项目贯穿整个过程中,它必须有一个全面的焦点。

执行阶段的项目。

实施阶段的工程造价管理是实施全过程项目管理。

项目实施阶段的工程造价管理可分为三个部分:投标管理施工管理和结算管理。

4.1 招标施工阶段的施工单位招标制度控制工程造价的有效手段,申办组织,可以提高成本效益的工程,并确保工程质量, 缩短建设周期,投资回报, 施工单位可充分利用招标的手段,有效控制成本。

施工编号10月7部令发布了“合同与施工合同定价管理” 明确指出,在工程招标使用库存。

这就要求建设单位进行招标, 在招标文件中,不仅包括通常的内容如债券投标前附表,招标债券合同的条件、合同协议条款、合同格式、技术规格、图纸、招标文件及其他参考格式,还必须提供工程清单招标作为参考文件的重要组成部分。
