The plastic mix is placed and consolidated in the formwork, then cured to facilitate the acceleration of the chemical hydration reaction lf the cement/water mix, resulting in hardened concrete. The finished product has high compressive strength, and low resistance to tension, such that its tensile strength is approximately one tenth lf its compressive strength. Consequently, tensile and shear reinforcement in the tensile regions of sections has to be provided to compensate for the weak tension regions in the reinforced concrete element.It is this deviation in the composition of a reinforces concrete section from the homogeneity of standard wood or steel sections that requires a modified approach to the basic principles of structural design. The two components of the heterogeneous reinforced concrete section are to be so arranged and proportioned that optimal use is made of the materials involved. This is possible because concrete can easily be given any desired shape by placing and compacting the wet mixture of the constituent ingredients are properly proportioned, the finished product becomes strong, durable, and, in combination with the reinforcing bars, adaptable for use as main members of any structural system.The techniques necessary for placing concrete depend on the type of member to be cast: that is, whether it is a column, a bean, a wall, a slab, a foundation. a mass columns, or an extension of previously placed and hardened concrete. For beams, columns, and walls, the forms should be well oiled after cleaning them, and the reinforcement should be cleared of rust and other harmful materials. In foundations, the earth should be compacted and thoroughly moistened to about 6 in. in depth to avoid absorption of the moisture present in the wet concrete. Concrete should always be placed in horizontal layers which are compacted by means of high frequency power-driven vibrators of either the immersion or external type, as the case requires, unless it is placed by pumping. It must be kept in mind, however, that over vibration can be harmful since it could cause segregation of the aggregate and bleeding of the concrete.Hydration of the cement takes place in the presence of moisture at temperatures above 50°F. It is necessary to maintain such a condition in order that the chemicalhydration reaction can take place. If drying is too rapid, surface cracking takes place. This would result in reduction of concrete strength due to cracking as well as the failure to attain full chemical hydration.It is clear that a large number of parameters have to be dealt with in proportioning a reinforced concrete element, such as geometrical width, depth, area of reinforcement, steel strain, concrete strain, steel stress, and so on. Consequently, trial and adjustment is necessary in the choice of concrete sections, with assumptions based on conditions at site, availability of the constituent materials, particular demands of the owners, architectural and headroom requirements, the applicable codes, and environmental reinforced concrete is often a site-constructed composite, in contrast to the standard mill-fabricated beam and column sections in steel structures.A trial section has to be chosen for each critical location in a structural system. The trial section has to be analyzed to determine if its nominal resisting strength is adequate to carry the applied factored load. Since more than one trial is often necessary to arrive at the required section, the first design input step generates into a series of trial-and-adjustment analyses.The trial-and –adjustment procedures for the choice of a concrete section lead to the convergence of analysis and design. Hence every design is an analysis once a trial section is chosen. The availability of handbooks, charts, and personal computers and programs supports this approach as a more efficient, compact, and speedy instructional method compared with the traditional approach of treating the analysis of reinforced concrete separately from pure design.2. EarthworkBecause earthmoving methods and costs change more quickly than those in any other branch of civil engineering, this is a field where there are real opportunities for the enthusiast. In 1935 most of the methods now in use for carrying and excavating earth with rubber-tyred equipment did not exist. Most earth was moved by narrow rail track, now relatively rare, and the main methods of excavation, with face shovel, backacter, or dragline or grab, though they are still widely used are only a few of the many current methods. To keep his knowledge of earthmoving equipment up to date an engineer must therefore spend tine studying modern machines. Generally the only reliable up-to-date information on excavators, loaders and transport is obtainable from the makers.Earthworks or earthmoving means cutting into ground where its surface is too high ( cuts ), and dumping the earth in other places where the surface is too low ( fills). Toreduce earthwork costs, the volume of the fills should be equal to the volume of the cuts and wherever possible the cuts should be placednear to fills of equal volume so as to reduce transport and double handlingof the fill. This work of earthwork design falls on the engineer who lays out the road since it is the layout of the earthwork more than anything else which decides its cheapness. From the available maps ahd levels, the engineering must try to reach as many decisions as possible in the drawing office by drawing cross sections of the earthwork. On the site when further information becomes available he can make changes in jis sections and layout,but the drawing lffice work will not have been lost. It will have helped him to reach the best solution in the shortest time.The cheapest way of moving earth is to take it directly out of the cut and drop it as fill with the same machine. This is not always possible, but when it canbe done it is ideal, being both quick and cheap. Draglines, bulldozers and face shovels an do this. The largest radius is obtained with the dragline,and the largest tonnage of earth is moved by the bulldozer, though only over short distances.The disadvantages of the dragline are that it must dig below itself, it cannot dig with force into compacted material, it cannot dig on steep slopws, and its dumping and digging are not accurate.Face shovels are between bulldozers and draglines, having a larger radius of action than bulldozers but less than draglines. They are anle to dig into a vertical cliff face in a way which would be dangerous tor a bulldozer operator and impossible for a dragline. Each piece of equipment should be level of their tracks and for deep digs in compact material a backacter is most useful, but its dumping radius is considerably less than that of the same escavator fitted with a face shovel.Rubber-tyred bowl scrapers are indispensable for fairly level digging where the distance of transport is too much tor a dragline or face shovel. They can dig the material deeply ( but only below themselves ) to a fairly flat surface, carry it hundreds of meters if need be, then drop it and level it roughly during the dumping. For hard digging it is often found economical to keep a pusher tractor ( wheeled or tracked ) on the digging site, to push each scraper as it returns to dig. As soon as the scraper is full,the pusher tractor returns to the beginning of the dig to heop to help the nest scraper.Bowl scrapers are often extremely powerful machines;many makers build scrapers of 8 cubic meters struck capacity, which carry 10 m ³heaped. The largest self-propelledscrapers are of 19 m ³ struck capacity ( 25 m ³ heaped )and they are driven by a tractor engine of 430 horse-powers.Dumpers are probably the commonest rubber-tyred transport since they can also conveniently be used for carrying concrete or other building materials. Dumpers have the earth container over the front axle on large rubber-tyred wheels, and the container tips forwards on most types, though in articulated dumpers the direction of tip can be widely varied. The smallest dumpers have a capacity of about 0.5 m ³, and the largest standard types are of about 4.5 m ³. Special types include the self-loading dumper of up to 4 m ³ and the articulated type of about 0.5 m ³. The distinction between dumpers and dump trucks must be remembered .dumpers tip forwards and the driver sits behind the load. Dump trucks are heavy, strengthened tipping lorries, the driver travels in front lf the load and the load is dumped behind him, so they are sometimes called rear-dump trucks.3. Safety of StructuresThe principal scope of specifications is to provide general principles and computational methods in order to verify safety of structures. The “ safety factor ”, which according to modern trends is independent of the nature and combination of the materials used, can usually be defined as the ratio between the conditions. This ratio is also proportional to the inverse of the probability ( risk ) of failure of the structure.Failure has to be considered not only as overall collapse of the structure but also as unserviceability or, according to a more precise. Common definition. As the reaching of a “ limit state ” which causes the construction not to accomplish the task it was designed for. There are two categories of limit state :(1)Ultimate limit sate, which corresponds to the highest value of the load-bearing capacity. Examples include local buckling or global instability of the structure; failure of some sections and subsequent transformation of the structure into a mechanism; failure by fatigue; elastic or plastic deformation or creep that cause a substantial change of the geometry of the structure; and sensitivity of the structure to alternating loads, to fire and to explosions.(2)Service limit states, which are functions of the use and durability of the structure. Examples include excessive deformations and displacements without instability; early or excessive cracks; large vibrations; and corrosion.Computational methods used to verify structures with respect to the different safety conditions can be separated into:(1)Deterministic methods, in which the main parameters are considered as nonrandom parameters.(2)Probabilistic methods, in which the main parameters are considered as random parameters.Alternatively, with respect to the different use of factors of safety, computational methods can be separated into:(1)Allowable stress method, in which the stresses computed under maximum loads are compared with the strength of the material reduced by given safety factors.(2)Limit states method, in which the structure may be proportioned on the basis of its maximum strength. This strength, as determined by rational analysis, shall not be less than that required to support a factored load equal to the sum of the factored live load and dead load ( ultimate state ).The stresses corresponding to working ( service ) conditions with unfactored live and dead loads are compared with prescribed values ( service limit state ) . From the four possible combinations of the first two and second two methods, we can obtain some useful computational methods. Generally, two combinations prevail:(1)deterministic methods, which make use of allowable stresses.(2)Probabilistic methods, which make use of limit states.The main advantage of probabilistic approaches is that, at least in theory, it is possible to scientifically take into account all random factors of safety, which are then combined to define the safety factor. probabilistic approaches depend upon :(1) Random distribution of strength of materials with respect to the conditions of fabrication and erection ( scatter of the values of mechanical properties through out the structure );(2) Uncertainty of the geometry of the cross-section sand of the structure ( faults and imperfections due to fabrication and erection of the structure );(3) Uncertainty of the predicted live loads and dead loads acting on the structure;(4)Uncertainty related to the approximation of the computational method used ( deviation of the actual stresses from computed stresses ).Furthermore, probabilistic theories mean that the allowable risk can be based on several factors, such as :(1) Importance of the construction and gravity of the damage by its failure;(2)Number of human lives which can be threatened by this failure;(3)Possibility and/or likelihood of repairing the structure;(4) Predicted life of the structure.All these factors are related to economic and social considerations such as：(1) Initial cost of the construction;(2) Amortization funds for the duration of the construction;(3) Cost of physical and material damage due to the failure of the construction;(4) Adverse impact on society;(5) Moral and psychological views.The definition of all these parameters, for a given safety factor, allows construction at the optimum cost. However, the difficulty of carrying out a complete probabilistic analysis has to be taken into account. For such an analysis the laws of the distribution of the live load and its induced stresses, of the scatter of mechanical properties of materials, and of the geometry of the cross-sections and the structure have to be known. Furthermore, it is difficult to interpret the interaction between the law of distribution of strength and that of stresses because both depend upon the nature of the material, on the cross-sections and upon the load acting on the structure. These practical difficulties can be overcome in two ways. The first is to apply different safety factors to the material and to the loads, without necessarily adopting the probabilistic criterion. The second is an approximate probabilistic method which introduces some simplifying assumptions ( semi-probabilistic methods ) .2. 中文翻译摘要：为了研究连续型拓扑优化理论在实际工程中的应用，该文给出了一种多层钢框架支撑体系连续型拓扑优化设计方法。

Its convenience, speed, low cost and versatility are being exploited on a daily basis in ever-changing ways. Together with its capacity to transform existing businesses, promote new businesses and facilitate exchange of information and data, its other striking attribute has been the speed with which this new technology has spread throughout the global economy.Keywords:The internet;Real Estate;ApplicatedThe number of computer hosts grew by more than ten-fold between 1995 and early 1999. The number of Web sites increased almost 100-fold, to over two million, between 1995 and 1998.Ｂy the year 2000, there will be approximately 400-500 million Internet users in the world, and the total number of Web sites will exceed five million.This new technology has the potential for affecting the real estate industry directly and indirectly. Directly, it may become a tool that allows a real estate business to expand its information and sales network. Indirectly, it may change the location equation where and how firms do business which in turn will affect the role of firms involved in real estate development, investment and transactions.Measuring the Spread of the WebThere are few reliable published statistics on Internet or Web use, and statistics reported by different analysts are often inconsistent. Our discussion of the Web and real estate is based on limited information from surveys and on examination of Web sites rather than on more comprehensive data. We have built our overview of the role of the World Wide Web and real estate by examining a variety of sources(including trade publications, existing Web sites, and our own survey of selected real estate firms)From E-mail to E-commerceBefore the advent of the World Wide Web, the Internet existed mostly for the purposes of e-mail, data transfers, newsgroups and bulletin boards, and its reach was limited primarily to the academic and the defense community. The technology itself was not particularly user-friendly, the network speed was not very high, the medium was limited to text and data, and accessing information was cumbersome and time-consuming. The browser technology greatly simplified usage, enabled multimedia information, and created interactive possibilities. The technology brought together TV entertainment, library information, news bulletins, communication and data in one desktop machine.Although initially the greatest patrons of the Internet were the academic community, the commercial sector quickly caught on to the potential of the Web. The private sector saw in the Web an opportunity to widen its marketing reach, lower costs of information dissemination, improve customer relations, and ultimately to conduct sales. Existing private sector Web sites can be roughly categorized into three types, as summarized. The most basic level is for simple information dissemination. The firm registers a Web site and develops a page giving basic company information. The second stage is an expansion of information, marketing goods and services or providing other customer information. The third stage is the addition of transactions tothe activities possible on the Web site.Most business sites at present are in Stage 2. The use of the World Wide Web for detailed information dissemination, and marketing has had several advantages. For the firm, marketing, information dissemination and customer services on the Web can be monitored and analyzed with some details unavailable from conventional methods of marketing using other media. Internet tools can now provide a firm with data on who accessed the site, which pages were visited most, heavily, from where and for how long. This information contributes to improved measures of the results of promotional efforts. The promotional costs associated with the Internet have also been very low. For example, in direct mail marketing, to send a one-page color brochure to 5,000 random addresses will cost upwards of $2,500. The cost of setting up a Web site could be one-tenth of this amount or less (although tracking and analysis can quickly add to the cost)?Many different sectors, including real estate, have found the Internet to be both efficient and cost-effective as a marketing device.The next logical step - a full-fledged office/store on the Web with transaction capability and commerce on the Internet is now being attempted in varying degrees depending on the firm's area of business. Retail sites selling products between $10 and $100, the kind that are traditionally part of a direct mail sales catalog, seem to be the ones having the greatest success(although 4% of sites sell products over $10,000 and another 13% sell products ranging from $100 to$9,999)?A number of retail sites have also harnessed a secondary revenue stream from advertising. Advertising revenues on the Web have crossed the billion-dollar mark and total Internet generated revenue will approach$100 billion this year.Consumers' Use of the WebSurveys of consumers using the Web suggest that a Web site does notsubstitute for the more traditional forms of business, but can greatly facilitate the run-up to the final transaction. The most common use of the Web is for information searching, closely followed by work-related uses, education, and entertainment. A significant majority of those that use the Web for shopping do so to carry out detailed research on product information（90%）and to do price comparisons（85%）. This more often leads to purchases through normal channels（67%）. Most of the online purchases tend to be of items that are standardized-four of the five top items bought on the Web, according to survey, are software, books, hardware and music (the fifth is travel). More than half of consumers who make purchases on the Web spend less than $500 in a six-month period.The demographics of Web users vary widely in age and income. Surveys by Georgia Tech, Active Media and Web indicate that the average age of Web users is 35 years, with average household income $67,000. Most are college educated (65%). A high proportion of the respondents (42%) has accessed real estate sites.Limits to the Web - Some "Catches" to the New Technology New technology is frequently a mixed blessing, and the World Wide Web is no exception. Apart from the teething troubles that any new technology faces and the time, as well as resources needed to learn, adapt and master it, the Web poses some unique issues and problems of its own. Consumers today are facing information overload of taxing proportions. It is not always easy, or even possible, to locate the relevant information on the Web, despite sophisticated search engines. Once the site is located, fancy graphics, complex linkages, labyrinthine routings, and a lot of irrelevant information may overwhelm the consumer - in short, poor and confusing site design can reduce the site's effectiveness.From the point of view of the business, there are two commonly heardcomplaints. First, the business may find that its site does not figure prominently on search results, limiting the number of customers reached. Second, for many firms, Web initiated leads are as yet few and far between. Real Estate Web SitesReal Estate firms and related businesses were among the early private sector pioneers of Internet use and have had a fast growing presence on the Web. presence on the Web. One example of the real estate sector's presence on the Internet in its pre-World Wide Web incarnation was the real estate classified bulletin board of Prodigy, the online service, which had listings for homes and other real estate. A few real estate related Web sites started in 1994 (generally regarded as the inaugural year of the Web). The New York City Real Estate Guide Web site, created in the summer of 1994, was one of the first to offer free access to the latest New York real estate information. By the summer of 1995, the site was receiving more than 100,000 inquiries a month.The real estate industry registered its entry on the Web in a dramatic way in 1995. By the end of that year there were close to 4,000 real estate Web sites. The content matter of the sites, as well as the mix of real estate related firms on the Web have changed over time. Initially, quite a few of the sites were residential real estate brokerages and listing guides, but fairly rapidly the list expanded to include commercial and retail listings, mortgage brokers,appraisers, architects, real estate attorneys, developers, construction firms, and suppliers. As investment vehicles for real estate expanded, REITs, publicly held firms, and investment advisors also added Web sites.The early real estate broker Web sites quickly took advantage of the unique features of the Web. Prospective customers could find out what properties were for sale or rent, look up detailed descriptions of each listing, view photographs and floor plans, and contact the broker by e-mail. Viewerscould also look up statistical and data reports on conditions in various geographical areas and on emerging macroeconomic trends.Ever since then, the real estate industry has been among the most enthusiastic users of the Web, by some measures accounting for 4% to 6% of commercial Web sites. A survey conducted by Real Estate Broker's Insider in early 1998 confirmed that nearly 95% of the respondents/brokers had a Web site, and more than 90% of the housing stock on sale at a given time is now listed on the Web. Indeed, because of the dispersed, localized nature of the role of information in real estate, the prospective gains from information dissemination, comparability, and Web links were particularly significant in real estate.For much of the real estate sector, the Internet generates not so much the actual transactions themselves, but creates initial leads that are later followed by transactions, purchases and sales. Web sites frequently lead to contacts that are then nurtured through telephone and person-to-person meetings. For residential real estate, Web activity includes residential searches, housing details, and pricing information (both on houses and mortgages), with follow-up contact with brokers. Real estate-related transactions are seen in the hospitality industry (making reservations for hotels and vacation homes and in online mortgage applications). Mortgage and home loan finance companies report both inquiries from mortgage shoppers who obtained initial information from their Web sites, as well as closing of loans through the Web, lead to great savings in time and overhead costs.It is not just the real estate professionals who are enthusiastic about their Internet presence, judging it to be as effective as print and radio advertising. Mortgage shoppers, homebuyers and vacation rental seekers as well applaud, in particular, the convenience it brings to the entire process of searching, researching, comparing, communicating and transacting business.Beyond these sectors, many other types of real-estate related firms are using the Web to broaden their market areas, increase the depth of their marketing, and to provide a range of services to existing customers. Commercial brokers provide not only information on available sites but also on market conditions for different locations and sometimes more in-depth economic analysis of a region. REITs and other investment firms provide detailed information on their products as well as background market or economic information. Public companies provide up-to-date stock quotes and quarterly and annual reports on the Web.Web Penetration and Use: The Experience of Leading Real Estate Firms We conducted a limited survey of a sample of leading real-estate related firms in the US and California. Responses from approximately 60 of these firms showed that over four-fifths had Web Sites by March 1999. 2 Of those with Web sites, one-third had inaugurated their sites by the end of 1996. Among the earliest with a Web presence were brokers, investment firms, lenders, business and financial services firms, law firms, residential developers, and a trade organization. Another third of the group were newcomers, with sites inaugurated in 1998 or early 1999. Commercial developers were prominent among this group, with residential developers, consultants and advisors, lenders, REITs and investment firms also among this group. Those without sites were more likely to be privately held firms with a relatively narrow base of activity (for example, a commercial developer centered in the San Francisco Bay Area)?Most with Web sites used their site to provide information about the company and to market services. In addition, about one-third marketed property from their site, providing detailed information on the characteristics of buildings available, surrounding communities, and other related data. Other Web site uses include employee recruiting, providing information formembers or investors, and disseminating related information on topics such as regulations or real estate markets.What does the Web specifically do for Real Estate?According to Activemedia, an internet research company, some of the sectors experiencing the greatest growth in terms of their presence on the Web in 1998 were computer hardware and software, real estate, publishing and information, finance and Internet services. A significant initial motivation for this rush for the Web is provided by, what can be termed, the "tiptoe" effect. The first ones on the Web had an additional advantage over those who did not; information on their services, products, home listings now be accessed conveniently by those with computers. The low setup cost, however, and the potential disadvantage of not having a Web presence has propelled others in the profession to set up their own sites.Real estate shares in some of the basic advantages of the Web mentioned earlier, such as ease of marketing, communication and feedback from clients, lowered costs of operations and convenience of customer service and support. In addition, the Web provides positive features specific to the real estate industry.Key elements include the following.1.Increased geographic reach.The Web has dramatically increased the geographic reach of both buyers and sellers. Although the "local" aspect of real estate will perhaps never be whittled away completely, there is no doubt that inquiries about properties can now emanate from far away to a much greater degree than before. This, in turn, potentially increases the size and "depth" of the market and makes it more efficient.2.Capability of visualization.In some sense, increased geographic reach has become possible due tothe other emergent feature of the Web, the capability of visualization. In its most state-of-the-art form, Web sites now allow prospective buyers to take virtual tours of homes, resorts, hotels and convention centers.3.Reduced transaction costs.The Web may reduce transactions costs. This has been particularly apparent in the case of mortgages. According to Fannie Mae, 1.5% of all mortgages were handled online this past year. The Web-attributable features that make this kind of a transaction possible are instantaneous comparability, interactive capability, online calculation, online applications, and continuous updating of the sites.4.Improved information dissemination.The Web offers broad opportunities for increasing the scope and depth of information provided by many different types of firms. A well constructed home page gives an overview of a firm's range of services or activities. Links allow the customer or client to learn much more detail about the selected items of most interest, while ignoring less relevant pieces of information. A number of sites take advantage of the ability to link to resources beyond the company's Web pages, linking customers and clients to related Web resources.Unlike retail sectors, such as books and computer hardware, the Web as yet has not become a threat to the "middle man" role of many real estate firms. Instead, it is more likely to be used as a means of expanding services offered or locations served. However, in the long term, the Web and related Internet technology have the potential to change the structure of business activity, which in turn will affect the demand for real estate in type if not in quantity. For example, some retailers already have closed stores while expanding sales on the Web. Also, the Internet has been seen as one factor allowing the decentralization of office space. These trends to date have notled to a decline, but rather to a redistribution in the demand for office, retail and warehouse space.These are summarized .Speculation on Potential Impact of Internet on Real Estate Industry.1.Shortening of Transaction Cycle2.Precise Market Targeting3.Transformed Competition4.Cost savings:a)Marketing,b)Sales,c)Operation5.Possibility of Disintermediation;Lowering of Commissionsbination of Comparison Shopping and Direct Sales7.Access to MBS Secondary MarketHow to Find the Real Estate Sector on the WebThere are a few key sites that can be used to access the broad range of real-estate related Web sites.

工程项目管理制度英文
In the field of engineering, project management plays a crucial role in ensuring the successful completion of projects. A well-defined project management system is essential to streamline processes, minimize risks, and achieve project objectives within the allocated time and budget. This article aims to provide an overview of an effective project management system specifically tailored for engineering projects.1. IntroductionEngineering projects are complex and involve various stakeholders, including clients, designers, contractors, suppliers, and regulatory authorities. A comprehensive project management system is designed to coordinate these stakeholders, facilitate communication, and ensure that all project activities are executed in a timely and efficient manner.2. Project InitiationThe first step in the project management system is project initiation. This involves defining the project scope, objectives, and deliverables. The project manager should work closely with the client to understand their requirements and expectations. A feasibility study may be conducted to assess the technical, economic, and operational aspects of the project.3. Project PlanningOnce the project is initiated, the next step is to develop a detailed project plan. This includes defining the project schedule, identifying the resources required, and establishing the budget. The following components are typically included in the project plan:- Work breakdown structure (WBS): This breaks down the project into smaller, manageable tasks.- Gantt chart: This visual representation of the project schedule helps in tracking progress and identifying critical paths.- Resource allocation: This involves assigning resources, such as personnel, equipment, and materials, to each task.- Budget estimation: This includes estimating the costs associated with each task and the overall project.- Risk management plan: This identifies potential risks and outlines mitigation strategies.4. Project ExecutionDuring the project execution phase, the project manager coordinates the activities of the project team. This involves:- Monitoring progress: Regularly reviewing the project schedule, budget, and quality to ensure that the project is on track.- Communication: Maintaining open lines of communication with all stakeholders to ensure that everyone is informed about the project status.- Change management: Handling any changes to the project scope, schedule, or budget, and obtaining necessary approvals.- Quality control: Ensuring that the project deliverables meet the required standards and specifications.5. Project Monitoring and ControlProject monitoring and control are essential to ensure that the project remains on track. This involves:- Tracking progress: Comparing the actual progress with the planned schedule and identifying any deviations.- Identifying and mitigating risks: Continuously monitoring forpotential risks and implementing mitigation strategies to minimize their impact.- Controlling costs: Monitoring the project budget and taking corrective actions if necessary.- Ensuring quality: Conducting quality assurance activities to ensurethat the project deliverables meet the required standards.6. Project ClosureThe final phase of the project management system is project closure. This involves:- Delivering the project deliverables to the client.- Conducting a project review to evaluate the project's performance and identify lessons learned.- Obtaining client approval and releasing the project team.- Archiving project documentation for future reference.7. ConclusionAn effective project management system is crucial for the successful execution of engineering projects. By following a structured approach, project managers can ensure that projects are completed on time, within budget, and meet the required quality standards. Implementing a robust project management system can lead to increased client satisfaction, reduced risks, and enhanced project performance.。

It encompasses a wide range of activities, from project planning and coordination to resource allocation and risk management. This article provides a comprehensive overview of project management in construction, exploring its key principles, processes, and best practices.Principles of Project Management.The fundamental principles of project management guide the way construction projects are planned, executed, and controlled. These principles include:Project Planning: Establishing a clear and detailed plan that outlines project objectives, scope, deliverables, and timelines.Communication: Maintaining effective communication among project stakeholders, including owners, contractors, suppliers, and consultants.Risk Management: Identifying and mitigating potential risks that may impact project outcomes.Collaboration: Fostering teamwork and collaboration among project members to achieve common goals.Control: Regularly monitoring and evaluating project progress to ensure adherence to plans and objectives.Project Management Processes.Project management in construction involves several key processes that are typically executed sequentially:1.

Engineering supervision system in China's Engineering constructionin the positionWith the dominance of China's socialist market economy, the determination of the project supervision system in China's highway construction is gradually becoming more mature. Talking about the project in the country, people always focus on project quality side, it seems that the focus of the task of supervision is to protect the quality of projects, in fact, it is very comprehensive, according to FIDIC provisions in the project construction, project quality, of course, crucial, but only to protect the project supervision of the three objectives (quality, duration, cost), one of these three goals are interrelated and influence, from different angles to protect the owners of the project efficiency. Of which cost control is also very important to the management aspect of this work, good or bad, is directly related to whether the quality of the project can achieve the desired goals, and whether the progress can be completed on time.First, the design phase of the design phase of SupervisionThe introduction of engineering supervision, determine a reasonable design, mature technology, reduce the construction phase of major design changes and program changes to occur, the effective cost control will play a certain role. Experts say: If the project supervision involved in the design stage, then, and can be ruled out, to correct 80% of the errors, but to the construction stage to be involved in supervision of works, at best, can only save 20% of the investment. According to the information briefing, a German university laboratory building, the original design is three and a basement, the project management company to meet the commission's space requirements and functional conditions, proposed to increase the layer to shorten the two-axis then the abolition of the basement. But also reduces the flow of people to evacuate distance (to the required standards), so modified after the design is not only reduced costs, has also been improved functionality, access to credit and praise of the municipal government. At present, China for engineering supervision at the design stage to introduce the practice is still rare, we should learn from foreign countries mature and developed system, the development of relevant systems, and standardize the market. Advocates strengthening the design phase of the supervision, control and management from a cost sense, ex ante control, prevention, which is scientific and reasonable. Therefore, to enhance the design stage to control the cost ofsupervision is necessary.Second, the construction phase of the SupervisionAs we all know, domestic and international construction markets are the dominant owners of a buyer's market, the construction of competition among enterprises is very cruel. In order to bid, bidders tend to almost zero profits or even below cost bids, but the owners often use low-cost way of winning. While the bidders promised to abide by the provisions of contract documents, but once the contract, they refused to the end there is no profit or losing money, so, often with inferior materials, do not follow standard construction, bribery, or layers of subcontracting means to profit. This time, the absence of an effective supervision mechanism, the victims can only be the owners.From the process, process control the cost of supervision of supervision engineer should not only be concerned with whether the works to meet the required quality goals, he should be the focus all the objectives of the project design, in the actual operation, the contractor engaged in construction prior to permanent per days must be carried out by a variety of inspection, testing, content or face a new job, workload, construction methods, measures, materials testing and sub-contracting part of the work or works submitted to the approval of supervisory engineer. The contractor can only work within the approved, without approval or beyond the approved engineer's work can not be recognized. At the same time is also an engineer approved the contractor to obtain a basis for progress payments. Engineers, contractors, any non-approved inputs (manpower, materials, equipment) will not receive compensation, meaning that there is no engineer's approval, the contractor shall not proceed to the next one process or face, shall not be put into construction materials, use, shall not subcontract part of the project or work.Supervision and Control of project cost from the cost of the engineering supervision of the project cost management goal is to project to be completed within the contract price can not be there far exceed estimates. Supervision of the strict monitoring of the project, due to the contractor causes the possibility of super-budget is almost zero. This is because: Engineering Super-budget, no more than two kinds of reasons, the first rise in unit labor and materials, first, during the construction works increased volume, while the contractor's bid is a commitment to its binding, and the contractor not entitled to their own works to increase the amount of the project, even if there are engineers, required the contractor to increase the input of resources toprotect the project design goals, the contractor has no right to be compensated, therefore, because in the tender document, the contractor can protect a large number of frequently cited the successful completion of the project personnel and mechanical equipment. From equipment costs, materials costs and equipment costs control supervision, materials costs in the capital projects account for about 70% of the entire cost. It is the project a major component of direct costs. Materials, equipment, high and low prices will directly affect the size of the construction costs.Thus, in the supervision process, can not be ignored that part. To introduce competition, and create competitive conditions. Owners can delegate the direct supervision through public tender selecting the suppliers, so that contractors can avoid unauthorized lower prices, delays in provider payments and thus lead to shoddy supplier, delivery is not timely, thereby affecting the progress of projects happening. The contractor in the preparation of tender prices, mainly the prices of materials and equipment owners and suppliers signed price quotation, by the suppliers of materials and equipment will be mainly transported to the scene by the supervising engineers and contractors to co-sign, the by the owner will focus on the procurement of materials and equipment shall be paid directly to suppliers.From the above procedures is easy to see the contractor in addition to supervising engineers no choice but to obey. This is because the supervising engineer contractor performance has a strong economic constraints means, economic means of payment by the project system and the deposit system, composition, they are the heads of the two contractors, "inhibition".The project payment system: in fact, the project payment system is to project the economic risk of being transferred to the contractor. Contractor must obtain economic benefits (the bid price and the difference between the actual cost of the project) prior advance money or other resources, that is: He had to buy the materials, equipment, payment of wages and other expenses, under the supervision of the supervising engineer contract documents all requests to create a project. Can only be the work of the contractor to complete the written approval of the supervisory engineer and the quality of bond, after deducting there from the owner to obtain compensation (for projects). If the contractor's work should not be so satisfied with supervision, he not only no hope of profit, and even the cost of inputs can not be recovered.Project Margin System: As a rule, signed contract before the contractor must pay the contract price equal to 10% of the performance bond or letter of guarantee. Thecontractor prior to commencement of course, can be obtained from the owners of 10% of the total contract price of the advance payment, but he must also be matched to the owners to submit a bond or letter of guarantee. Even if the contractor has received final acceptance certificates from the project, he will be leaving 5% of total contract price of the retention money. Here the performance bond and retention payments totaling 15% of the project contract price, far greater than the contractor's profit margin. The contractor's default can cause bond be forfeited, and whether the breach of contract only to evaluate the supervisory engineer.Third, completion of the project closing of SupervisionThe first job done in several stages, based on the completion of settlement on a lot easier. Labor Exchange acceptance of the project handled immediately after completion of billing processing. Completion of the contract price settlement value is value of claims already liquidated damages.According to FIDIC terms or model of China's construction contract terms and the actual text of the provisions of the terms of the contract is signed: involving construction claims and breach of contract issues, supervision engineers must clearly define the responsibilities to minimize the claims, to reduce the claim should note the following: strengthening contract management, improve the terms of the contract; before projects should be fully prepared to work; enhance the design of the review, the timely detection of problems in the design to avoid the construction.Engineering design changes due to claims arising; to strengthen quality management, and strengthen the quality of tracking, to avoid or reduce the contract sample tests or works outside the review of claims arising; to improve the quality of supervision engineers found that claims in a timely manner.In short, the supervision engineer in Cost Control of the importance of the role and status is beyond question, supervision is entrusted by the owners on the implementation of the project to conduct supervision and management, reform and opening up of China's foreign towards WTO needs. Project Management is a need for a variety of professional and technical, economic, legal and other integrated management of multi-disciplinary knowledge and skills in intellectual-intensive service work, which requires supervisors controlling costs, management contracts and information, the ability to mediate economic disputes, continually improve their own quality, and enhance awareness of contract management, improve the legal system. To this end, the state unit of the Ministry of Construction Supervision of social hierarchyand the corresponding conditions and qualification standards, supervision of qualified engineers to make separate provision accordingly. Project Management in China has generally been carried out, as a mature project management experience in the management of cost control will certainly play a key role.。

建筑施工质量管理中英文对照外文翻译文献中英文资料翻译Building construction quality managementAbstract：adhere to the quality first, improve the management level, improve the quality of construction is the key, only to meet the required quality standards and user requirements under the premise of quality, time limit for a project, cost, to meet the requirements, to provide more high-quality, safe, economical and applicable building products. Based on this, the building construction quality management of.Key words: housing construction building construction quality management1 strengthen training, selection of construction personnel is laying the quality control personnel foundationEngineering quality were all participants in the project construction technology management, operating personnel coordination work results, so construction workers is to form the main factor of project quality. To control the engineering quality first is the training and selection of construction personnel, improving their comprehensive quality. We should improve their quality awareness, according to comprehensive quality regardless of idea construction personnel must establish five concepts: the concept of quality first, pre-control priority idea, talk with data concept and social benefit and enterprise benefit and comprehensive benefit idea. The second is the construction of the technical quality of personnel, management, construction personnel should have higher quality planning and management capacity, production personnel should have superb technical ability, be strict in one's demands of the style of work, strictimplementation of quality standards and procedures of the legal concept, service personnel should do good technology and service life, can be with excellent service indirectly to ensure engineering quality.2 give full play to QC quality control functionAccording to "the anti-seizure combination, prevention first " principle is carried out actively " tell, help, anti, card" scientific examination method, and the constructionpersonnel together, common to the owners of construction process, responsible, quality control personnel, users, the construction personnel to establish new relations of cooperation, quality inspection staff and the construction site operations personnel is consistent, it is to provide users with high quality, satisfaction of building products. But the construction production is busy, to snatch the project schedule is loosen quality management tendency occurs. This led to check the quality of the project is checked with contradictions between. To give full play to the initiative of the staff to check the quality of the project, it is necessary to establish the authority of the quality inspection personnel, it is very necessary and important.3 following a case analysis gradually quality management, engineering survey:The territory of Hechi a building for the underground layer, on the ground twenty-two, twenty-five buildings, covers an area of 2550.4 square meters, building a total height of 79.950 meters, construction area of 4008 square meters underground, on the ground 36855 square meters, balcony area is 1570.1 square meters; the main design reasonable service life is 50 years; building fire grade two, seismic fortification intensity is 7 degrees, frame aseismic grade two; the ground floor to the ground floorthree layer 2-A axis 2-6 axis and2-17 axis short limb shear wall seismic rating for a class, the rest of shear wall seismic grade two. The project uses the base form of prestressed high-strength concrete pipe pile, structure type for the cast-in-place reinforced concrete frame shear wall structure.4 construction managementOn the construction quality management, mainly involves three aspects, one is about the design, survey and document review management. On design, reconnaissance unit quality behavior and results of the activities of the supervision, the emphasis is placed on the design, survey and document review supervisory control. If the violation of the relevant laws, regulations and mandatory standards for the design and survey documents, can be through direct economic penalties and legal sanctions, enabling direct responsibility assumed by the error caused by negligence or intentional quality responsibility. Two of the activities of the bidding management, focuses on the construction bidding supervision, market supervision and quality supervision the effective integration, through the quality supervision to promote the market competition and standardization of the benign operation, effectively through market operation, to ensure the validity of quality supervision. Three isthe text of the contract supervision, is the focus of construction contract supervision, quality management standardization and legalization to fulfil the terms of the contract, the legal effect of contract binding the construction quality and results. By analyzing the three aspects of examination and supervision, to achieve the government's construction qualityof the implementation process control and supervision. Before the construction, in the final analysis is the emphasis of quality management for owners of quality behavior management, because the owner of all these activities of the organizers, decision makers, which is the standard construction owner quality behavior and results of the activities of the important measures.5 construction management5.1 Lraw materials quality controlMaterial quality engineering construction quality is the key, use of raw materials does not meet the requirements of engineering, engineering quality can not meet the requirements. Therefore, in the construction quality control of stop before construction on material quality control, to ensure the quality of materials, in order to improve construction quality. For the control of materials, first of all to the common material supply necessary audit, select qualified suppliers for the supply of materials. Secondly, to approach the necessary inspection of raw materials, including: quality inspection report of the inspection, the inspection of appearance, physical and chemical inspection inspection. Through a series of tests to ensure the quality of the raw materials entering.5.2 procedures and time limit controlTo implement the handover inspection system, on the procedures of unqualified shall enter into next working procedure construction. At the same time construction quality affected by seasons, the reasonable arrangement of construction schedule is to ensure the engineering quality are important measures, and blindly rush period will inevitably lead to serious consequences. Quality control step is to establish quality control,selected key and key technology to undertake the key is checked, the two is to strengthen the operation of the management, project quality is good or bad, depends to some extent on the construction of personnel operation level.5.3 increase on-site inspectionsQuality management in the construction site should strive to grasp first-hand information, and strive to achieve the timely control, for the occurrence of the problemmust accomplish early discovery, early correction of bad old practices die hard, avoid, avoid large loss. For example, in the masonry tie bar examination, if taken after the completion of a masonry opening examination, is not easy to check, and to identify the problems are also difficult to remedy, but in the on-site inspection in a timely manner to solve, can avoid bigger loss, but also easy to get the cooperation.The entity quality inspection methods should adopt scientific monitoring instruments and equipment, to provide accurate, reliable and convincing data, strengthen the government engineering quality supervision and inspection of scientific and authoritative. Through the supervision, to ensure the implementation of mandatory standards, ensure the construction of law, regulations and standard carry out, from macroscopical overall grasp the construction project quality and structure safety. In addition, in strengthening program management at the same time, we must strengthen the technical control. Technology control method using standard evaluation method is better. Evaluation of standard methods are mainly as follows: one is the on site quality assurance condition examination and evaluation, two is the completion of the project the detection results of the examination and evaluation, three ison site quality assurance data examination and evaluation, four of engineering entity size deviation of the measured, five is for the completion of engineering the macro visual inspection evaluation.5.4 after the completion of the managementAfter the completion of the quality management of construction projects is put into use check management. First of all to ensure that do not meet the quality standards of the project can not be put into use, avoid inferior project to the state and public users cause direct harm and influence. The second is the decoration, repair and maintenance of quality supervision in construction project whole life quality management category : one is to eliminate or reduce due to renovation, maintenance process caused by irregularities on the construction engineering foundation, body structure and environmental quality, damage, cause quality accident. Two is prevented due to repair, maintenance quality is not up to the requirements to the state and public users production and living environment caused by direct damage. At this stage of the supervision should be emphasized good two close: it is strictly for its completion and acceptance review, supervision, to ensure that the registration of the reliability, authority and effectiveness. Two is to enhance the decoration, maintenance of quality management in the process, so that construction project whole lifequality objectives are effective implementation, for users to create a safe, comfortable, healthy production, living environment, so that the construction quality and realizing the sustainable development. Advocating and implementing project quality insurance, the project quality management into economic management category, to solve engineering after the delivery ofquality problem tenants to find the responsible party for any menace from the "rear".This phase is the project by construction to use or production of mark; is on engineering quality inspection the necessary link; is the guarantee contract task is finished in the round, improve project quality level of final checks. The unit after the completion of the project, must undertake the final inspection and test. Unit engineering technical person in charge should be prepared for the demands of information collected materials, equipment, component quality certificate of materials, a variety of material test data, record of concealed work, construction records records. By the technical director of project organization project technology, quality, production and other relevant professional and technical personnel to the scene inspection and evaluation. To identify the construction quality defects should be corrected, and should be corrected once again after the verification to demonstrate conformity. T o ensure engineering quality accord with mandatory standard design documents and the requirements of the contract, the employer, the Ministry of supervision of the project completion report. Attended by the construction unit of the organization of the main parties involved in the completion of initial inspection, acceptance procedure.endingProject, quality, the quality of housing construction related to people's daily life and the safety of life and property. In recent years, the housing quality problems have already become the focus of public attention, annual 3.15 consumer rights day, China Consumers Association published by consumer complaints the largest of the ten major categories of commodities, the housing quality problems at the front. Therefore, constructionmanagement in many aspects, quality management is the key and core. Only do a good job in building engineering construction quality planning and housing construction quality control, to create more quality engineering.Reference.[1 ] Building Engineering ( Construction Management ) [ J].

工程管理毕业论文外文文献及翻译BIM Beyond Boundaries
工程管理毕业论文外文文献及翻译BIM BeyondBoundaries外文文献:BIM Beyond BoundariesSeptember 10, 2012 ? by Randy DeutschAbstract: Opting for depth over breadth of expertise is a false choice that will lead individuals, organizations, the profession, and industry in the wrong direction.Keywords: BIM, expertise, anti-learning, master builderSeveral forces are converging to create an unprecedented and timely opportunity for organizations that have embraced building information modeling (BIM). These forces —including the rise of the expert, the growing complexity and speedof projects, and BIM’sincreasing recognition as an enabler, catalyst, and facilitator of team collaboration — also presentsignificant challenges that can be overcome with the right approach and mindset.At one time, being an expert meant knowing more than one’s competitors in a particularfield. Firms that reinforced their expert culture hoarded information, which resulted in silos of expertise. Today, many firms are looking to hire people perceived as building and software technologyexperts, shortsightedly addressing today’s needs at the expense of tomorrow’s. While architects have always been trees with many branches, our current economic climate has discouraged them from being anythingbut palm trees: all trunk, no branches.And yet things change so quickly that those who went to bed experts are unlikely to wake up experts in the morning. Due to the speed and complexity of projects, we do not have time to acquire knowledge the old way — slowly, over time, through traditional means. Even when we supplement our book learning with conferences, webinars, and continuing education, it is impossible to keep up with the flow of new information in our industry.Expertise today is a much more social, fluid, and iterative process than it used to be. Being an expert is no longer about telling people what you know so much as understanding what questions to ask, who to ask, and applying knowledge flexibly and contextually to the specificsituation at hand. Expertise has often been associated with teaching and mentoring. Today it’smore concerned with learning than knowing: less to do withcontinuing education and more with practicing and engaging in continuous education.Social media presents the would-be expert with both opportunitiesand challenges. Working- 1 -with the understanding that somebody somewhere has already done what you are trying to do, design professionals, like agile technology experts, can find what they’re looking for by tapping into their networks and aggregating the responses. Conversely, due to the rise of social media, virtually all anyone has to do today to be considered a technology expert is to call themselves one. Because social networks allow people to proclaim themselves experts, it can be hard to know who to turn to, resulting in the rise of otherwise unnecessary certifications.An expert today is someone whose network, community, or team deems him or her so. Such acknowledgment from one’s community can be considered a form of social certification. To grow one’s professional reputation, expertise in BIM counter-intuitively requires unlearning, detachment, collaboration, and developing both deep skills and broad interests.BIM EXPERTISE REQUIRES UNLEARNINGAs we grow in our careers, we tend to focus more on people issues and less on technology. We also tend to cooperate conditionally, responding to the behavior of others. This has huge implications for design and construction professionals who might be naturally collaborative —through sharing knowledge, learning, mentoring, and teaching — but are otherwise conditionedand tempered by the culture of the firm where they work.Working in BIM provides an unprecedented opportunity to learn: how buildings go together, how projects are scheduled, cost implications of decisions, and impact on the environment. At the same time, there is a great deal we still need to unlearn with BIM. We can start by asking some questions: Which aspects of the traditional design process change with BIM and which stay the same? What knowledge, methods and strategies must be abandoned due to BIM and what is critical to keep? And perhaps most important: What, while learning to work in BIM, needs to be unlearned?While unlearning habits we picked up working in CAD would seem like a good place to start, there’s also a great deal we need to unlearn in order to return to our original sharing attitude and cooperative ways. These include bad habits we’ve acquired since we left the cocoon of school and embarked on the hard knocks of a career in architecture and construction, where we may have learned to be mistrustful, skeptical, competitive, secretive, and working independently in silos. In doing so, we’ve unlearned many of the critical natural habits, attitu des, and mindsets necessary to work effectively and collaboratively on integrated teams.- 2 -BIM EXPERTISE REQUIRES DETACHMENTFrom Japanese martial arts there’s the concept of shuhari: First learn, then detach, and finally transcend. As consultant Ian Rusk has explained, shu, ha, and ri are considered three phases of knowledge thatone passes through in the study of an art. They can be described as the phases of traditional knowledge, breaking with tradition, and transcending it.Working in BIM, we need to address all three steps to meet our goals. Of the steps, the second (detachment, or breaking with tradition) is the most important. Detachment requires that we remain flexible and agile while learning, not holding on tightly to our ideas, agendas, or prejudices, so that we can move beyond them.BIM EXPERTISE REQUIRES COLLABORATIONWhile we as an industry have now lived with BIM for more than two decades, most firms have acquired and implemented the technologyprimarily as a visualization and coordination tool in the past several years. We appear to have reached a standstill in the software’s use, with manyfirm leaders wondering how to make the leap to more advanced uses. Further mastery of the application through traditional means won’t help us get there. If we are to achieve our personal, organizational, professional, and industry-wide goals of fully participating in public, community, creative, and economic life, something more needs to happen.Achieving higher levels of BIM use — including analysis, computation, and fabrication —requires skills and a mindset that allow us to work productively and effectively in a collaborative setting. Working with BIM enables but doesn’t necessarily lead to collaboration. We each have to decidewhether or not to look beyond BIM as a tool and embrace it as a process. When recognized as a process, BIM can be a powerful catalyst and facilitator of team collaboration.BIM EXPERTISE REQUIRES DEPTH AND BREADTHIt would be a mistake to assume that expertise in BIM as a technology alone will lead to greater leadership opportunities on integrated teams. In this capacity, BIM requires attention to acquiring skills that, while easy to attain, can be overlooked if we focus primarily on the software tools.With BIM, technical expertise should not be considered moreimportant than increasing one’s social intelligence, empathy, or the ability to relate well with others. Additionally, the conventional window for achieving technological expertise is too long. Better that one achieves a- 3 -high level of BIM competency motivated by passion and curiosity. Having competency in one subject doesn’t preclude you from addressing others. In fact, it can be a determinant for doing so.Being versatile flies in the face of current thinking that to succeed we should bolster our strengths over our weaknesses. The answer to Should I be a specialist or generalist? is yes. There must be people who can see the details as well as those who can see the big picture. One gift of the design professional is the rare (and underappreciated)ability to do both simultaneously. As with any hybrid — generalizing specialist or specializing generalist —one’s strength provides the confidence to contribute openly from many vantage points and perspectives.It is critical for “T-shaped” experts to reach out and make connections (the horizontal arm ofthe T) in all the areas they know little or nothing about from their base of technical competence (the vertical arm of the T). T-shaped experts have confidence because of their assurance that they know or do one thing well. Their confidence allows them to see as others see by means of — notthrough —what they know. Their expertise doesn’t color their perception so much as provide a home base to venture from and return to with some assurance that they’ll maintain their bearings when venturing out across the table.Broad-minded design professionals often find themselves in the roleof “anti-experts,”approaching challenges from the perspective of the outsider. To this Paula Scher of Pentagram said, “When I’m totally unqualified for a job, that’s when I do my best work.” Once we balance,own, and ultimately realize our expert and anti-expert selves, we(as a community, profession, and industry) will do our best work.WHAT DO WE DO NOW?Firms want to know how to optimize their work processes to become more efficient at what they do best, to remain competitive by leveraging the competitive advantage of BIM and integrated design. One of the ironies facing the in dustry is that in order to master BIM, don’t learn more BIM. Instead, do other things.What will bring about greater efficiencies and effectiveness, increase productivity and deliver value, is not additional technology knowledge but our ability to communicate, relate, work together, think like one another, have empathy, understand, and listen. If design professionals want to lead they will do so not by increasing their depth but by benefit of broader capabilities involving their reach.- 4 -What do we do now? Go wide and deep. Go against common wisdom and fortify your soft skills, your reach and wingspan. To master BIM you have to transcend BIM.We need to develop both sides of ourselves in order to move beyond our own and others’ biases and anticipate consequences for courses of action before they are acted upon. We need to develop the ability to put the project first, navigate iRooms and packed conference tables to get our ideas and points across, be able to read people for overt and subliminal responses, have the confidence to ask questions without feeling threatened and be asked questions without becoming defensive. It is as though we have placed so much emphasis on the bricks we’veforgotten the mortar that allows us to communicate genuinely, to relate well with one another and integrate.Having to choose between depth and breadth is a false choice that heads our profession and industry in the wrong direction. Rather than focusing on one over the other, we need to develop simultaneously vertical deep skills and horizontal soft skills, to work on our strengths and weaknesses, to be expert and anti-expert, specialist and generalist, to design from evidence and from intuition, to be task- and people-oriented, to have mastery over one thing and be a jack-of-all-trades.As one blog commenter recently asserted, “In order to practice architecture well, you need tounderstand a lot of things that aren’t architecture.” BIM technology experts know one thing. To flourish and persevere, we need to know and do many things.Often overlooked in mutual mentoring of computer technology and building technology by senior and junior staff are basic people skills: listening, questioning, negotiating, collaborating, communicating. The concern is that the emerging design professional — adept at BIM tools while learning how buildings come together —won’t learn the necessary communication andpeople management skills to negotiate a table full of teammates onan integrated team. These skills need to be nurtured, mentored, and acquired as assuredly as computer and building technology skills. Theseskills require the same amount of deliberate practice and feedback as the mastery of technology skills. Developing complementary,collaborative skills is as critical as becoming competent with the technology. As Ernest Boyer anticipated, “The future belongs to the integrators.” And that future has arrived.Succeeding in practice today is a both/and, not an either/or, proposition. Design professionals must be both BIM technologist and building technologist. Those who accept this- 5 -model will lead, persevere, and flourish in our new economy.Last year in Design Intelligence, Stephen Fiskum wrote, “One thing is certain: The solution to the current malaise in our profession is not for us to go broader but to go deeper” (“Preparing for a New Practice Paradigm,” January/February 2010). This is a new world: By going wider anddeeper we provide owners and our organizations with the most value and increased productivity. Working effectively and collaboratively in BIM will help us transcend our current state, bridge the gap, and cross over to more advanced uses.THE MULTIDISCIPLINARY MINDSETIt is not just that the integrated team is now multidisciplinary,but we each must become multidisciplinary. Doing so requires a multidisciplinary mindset. This entails empathy, a genuine appreciationfor others’ ideas, seeing from many perspectives, and anticipating possibleconsequences to any course of action. An industry representative recently stated in a public forum, “I don’t want the architect tothink like a structural engineer. I need for him to think like an architect!” To leverage our technology tools and work processes, being an architect today means that we think like a structural engineer aswell as a contractor and owner. Doing so doesn’t take away from architects’ role but increases their credibility by making them more effective andinfluential at what they do well.Working in BIM — inward focused, object-oriented, filling-in dialog boxes — discouragesthis mindset. It is a mistake to think that those who work in BIMare technicians and that a firm principal or senior designer who seesthe big picture will mediate between the model and the world in whichthe model operates. Leaders must see to it that their teams look outward, keeping an eye on the model while seeing the horizon.THE TECHNOLOGY/SOCIAL CONTINUUMWorking in CAD, there are those who focus on drafting and those more adept at communication, negotiation, and persuasion. With BIM, technical understanding and people know-how must exist in each and every design professional.The majority of BIM-related literature has been focused on the technology, not on the people who use it. People issues and attitudes are the main impediment to the collaborative work processes enabled by the technology. Human issues, issues of communication and collaboration, firm culture, motivation, and workflow — all exacerbated by the advent of BIM into the- 6 -workplace — are an even greater challenge than the admittedly considerable software application and technical problems associated with BIM’s use.LEADING FROM THE MODELWorking in CAD, a senior team member would redline an emerging employee’s work. Leadership was decidedly top-down: Someone senior designed or detailed, and someone less senior drew it up. The problem was that the senior team member never knew whether the emerging employee understood what was being drawn.Working in BIM provides a completely different work flow — one we have yet to leveragefully. Because those on the front lines are not only the first to discover clashes and inconsistencies but also to visualize what something looks like and how it might function, BIM allows our emerging talent to lead the process — to learn on the job while recognizingtheirpower from their privileged position of the first look in the model.The new leadership mandate in this process is for architects to lead from their involvement in the BIM environment. Leading from the modelcan be likened to leading from the middle in that BIM requires and even enables followership, and servant- and situational-leadership, as opposed to top-down or command-and-control. While leadershiphistorically has been top-down, working in BIM and on integrated teams changes that. Leading in BIM and integrated design is more similar to followership, in which middle managers lead from within the organization. Thus with BIM, the top-down and bottom-up approaches converge, where leading from the middle becomes leading from the model.BIM AND THE MASTER BUILDER TEAMArchitects who find themselves on increasingly large teams must find a way to lead and regain their voice in the design and construction process. If architects learn how to design buildings that are optimized to give owners, contractors, and other team members what they need — of high quality, low cost, sooner, with less waste, while acquiring the mindsets, attitudes, and skills necessary to collaborate with others —then architects will be trusted, newly esteemed, andreturn to their desired leadership role. What is critical is notthat we linearly help emerging professionals move from technical experts to leaders but to be technical experts and project, team, and process leaders at the same time. Expertise is cultivated by creating the right conditions for experts to flourish; people cannot be forced to learn and grow.- 7 -Many A/E/C professionals are stressing the role of the team over the role of any one individual mastering any one subject or technology in advancing practice. The general consensus is that appointing any one individual as master of the project is largely irrelevant. Instead, the architect who works in BIM serves as master facilitator or strategic orchestrator on integrated teams. By working with as well as through others, we get the most out of fellow teammates.The concept of the composite master builder is the brainchild of visionary environmentalist Bill Reed. The term recasts the historical single master builder (or virtual master builder) as a diverse group of professionals working together toward a common end: the master builder team. The intention is to bring all specialists together, allowing them to function as if they were one mind. A better prescription for what ails our industry would be hard to find.- 8 -中文译文:超越边界的BIM2012年9月10，兰迪•多伊奇摘要: 在BIM 应用中，对于专业的深度要求超过了广度是一个错误的选择，这将使个人、组织，以及这个职业和整个产业走向错误的方向。

Concrete Construction matterT. Pauly, M. J. N. PriestleyAbstractViewed in terms of accepted practices, concrete construction operations leave much to be desired with respect to the quality, serviceability, and safety of completed structures. The shortcomings of these operations became abundantly clear when a magnitude 7.6 earthquake struck northern Paki-stan on October 8, 2005, destroying thousands of buildings, damaging bridges, and killing an esti-mated 79,000 people. The unusually low quality of construction operations prevalent was a major cause of the immense devastation.Keywords: Concrete Placing Curing Construction TechnologyPlacing ConcreteIf concrete is placed in the surface, the sur-face should be filled with water sufficiently to prevent it from absorbing the concrete of its water. If fresh concrete is to be placed on or nearby to concrete that has solidified, the surface of the placed concrete should be cleaned absolutely, preferably with a high-pressure air or water jet or steel-wire brushes. The surface should be wet, but there should be no much water. A little quantity of cement grout should be brushed over the whole area, and then followed immediately with the application of a 1/2-in Layer of mortar. The fresh concrete should be placed on or against the mortar.In order to decrease the disintegration re-sulting from carriage after it is placed. The con-crete should be placed as nearly as probably in itsfinal point. It should be placed in layers to permit uniform compaction. The time interval between the placing of layers should be limited to assure perfect bond between the fresh and previously placed concrete.In placing concrete in deeper patters, a ves-sel should be used to limit the free fall to not over 3 or 4 ft, in order to prevent concrete disintegra-tion. The vessel is a pipe made of lightweight metal, having adjustable lengths and attached to the bottom of a hopper into which the concrete is deposited. As the patters are filled, sections of the pipe may be removed.Immediately after the concrete is placed, it should be compacted by hand pudding or a me-chanical vibrator to eliminate voids. The vibrator should be left in one position only long enough to reduce the concrete around it to a plastic mass; then the vibrator should be moved, or disintegra-tion of the aggregate will occur. In general, the vibrator should not be permitted to penetrate concrete in the prior lift.The mainly advantage of vibrating is that it permits the use of a drier concrete, which has a higher strength because of the reduced water content. Among the advantages of vibrating con-crete are the following:1.The decreased water permits a reduction in the cement and fine aggregate because less cement paste is needed.2.The lower water content decreases shrinkage and voids.3.The drier concrete decreases the cost of finishing the surface.4.Mechanical vibration may replace three to eight hand puddles.5.The lower water content increases the strength of the concrete.6.The drier mixture permits theremoval of some patters more quickly, which may reduce the cost of patters.Curing ConcreteIf concrete is to gain its maximum strength and other desirable properties, it should be cured with adequate moisture and at a favorable tem-perature. Failure to provide these conditions may result in an inferior concrete.The initial moisture in concrete is adequate to hydrate all the cement, provided it is not should replace the moisture that does evaporate. This may be accomplished by many methods, such as leaving the patters in place, keeping the surface wet, or covering the surface with a liquid curing compound, which comes being to a water-tight membrane that prevents the escape of the initial water. Curing compounds may be applied by brushes or pressure sprayers. A gallon will cover 200 to 300 sq ft.Concrete should be placed at a temperature not less than 40 or more than 80°F.A lower tem-perature will decrease the rate of setting, while ahigher temperature will decrease the ultimate strength.Placing Concrete in Cold WeatherWhen the concrete is placed during cold weather, it is usually necessary to preheat the water, the aggregate, or both in order that the ini-tial temperature will assure an initial set and gain in strength .Preheating the water is the most ef-fective method of providing the necessary tem-perature. For this purpose a water reservoir should be equipped with pipe coils through which steam can be passed, or steam may bedischarged directly into the water, several outlets being used to given better distribution of the heat.When the temperatures of the mixtures are known, some specific charts may be used to cal-culate the temperature of concrete. A straight line pass all three scales, passing through every two known temperatures, will assure the determina-tion of the third temperature. If the surface of sand isdry, the fact lines of the scales giving the temperature of concrete should be used. However, if the sand contains about 3 percent moisture, the dotted lines should be used.Specifications usually demand that freshly placed concrete shall be kept at a temperature of not less than 70°F for 3 days or 50°F for 5 days after it is placed. Some proper method must be provided to keep the demanded temperature when the cold weather is estimated.Reinforcing steels for concreteCompared with concrete, steel is a high strength material. The useful strength of ordinary reinforcing steels in tension as well as compres-sion, i.e., the yield strength, is about 15 times the compressive strength of common structural con-crete, and well over 100 times its tensile strength. On the other hand, steel is a high-cost material compared with concrete. It follow that the two materials are the best used in combination if theconcrete is made to resist the compressive stresses and the compressive force, longitudinal steel reinforcing bars are located close to the ten-sion face to resist the tension force., and usually additional steel bars are so disposed that they re-sist the inclined tension stresses that are caused by the shear force in the beams. However, rein-forcement is also used for resisting compressive forces primarily where it is desired to reduce the cross-sectional dimensions of compression members, as in the lower-floor columns of multi-story buildings. Even if no such necessity exits , a minimum amount of reinforce- ment is placed in all compression members to safeguard them against the effects of small accidental bending moments that might crack and even fail an unre-inforced member.For most effective reinforcing action, it is essential that steel and concrete deform together, i. e., that there be a sufficiently strong bond be-tween the two materials to ensure that no relative movements of the steel bars and the surrounding concrete occur. This bond is provided by the rela-tively large chemical adhesion which develops at the steel-concrete interface, by the natural roughness of the mill scale of hot-rolled rein-forcing bars , and by the closely spaced rib-shap-ed surface deformations with which reinforcing bars are furnished in order to provide a high de-gree of interlocking of the two materials.Steel is used in two different ways in con-crete structures: as reinforcing steel and as prestressing steel .reinforcing steel is placed in the forms prior to casting of the concrete. Stresses in the steel, as in the hardened concrete, are caused only by the loads on the structure, except for possible parasitic stresses from shrinkage or similar causes. In contrast, in priestesses concrete structures large tension forces are applied to the reinforcement prior to letting it act jointly with the concrete in resistingexternal.The most common type of reinforcing steel is in the form of round bars, sometimes called rebars, available in a large range of diameters,from 10 to 35 mm for ordinary applications and in two heavy bar sizes off 44 and 57 mm these bars are furnished with surface deformations for the purpose of increasing resistance to slip be-tween steel and concrete minimum requirements for these deformations have been developed in experimental research. Different bar producers use different patterns, all of which satisfy these requirements.Welding of rebars in making splices, or for convenience in fabricating reinforcing cages for placement in the forms, may result in metal-lurgical changes that reduce both strength and ductility, and special restrictions must be placed both strength and ductility, and special restric-tions must be placed both on the type of steel used and the welding procedures the provisions of ASTM A706 relatespecifically to welding.In reinforced concrete a long-time trend is evident toward the use of higher strength materi-als, both steel and concrete.Reinforcing bars with 40ksi yield stress , almost standard 20 years ago , have largely been replaced by bars with 60ksi yield stress , both because they are more economical and because their use tends to reduce congestion of steel in the forms .The ACI Code permits reinforcing steels up to Fy=80ksi. Such high strength steels usually yield gradually but have no yield plateau in this situation the ACI Code requires that at the speci-fied minimum yield strength the total strain shall not exceed 0.0035 this is necessary to make cur-rent design methods, which were developed for sharp-yielding steels with a yield plateau, appli-cable to such higher strength steels. there is no ASTM specification for deformed bars may be used , according to the ACI Code , providing they meet the requirements stated under special circumstances steel in this higher strength range has its place, e.g., in lower-story columns of high-rise buildings.In order to minimize corrosion of rein-forcement and consequent spelling of concrete under sever exposure conditions such as in bridge decks subjected to deicing chemicals , galvanized or epoxy-coated rebars may be specified.Repair of Concrete StructuresReinforced concrete is generally a very du-rable structural material and very little repair work is usually needed. However, its durability can be affected by a variety of causes, including those of design and construction faults, use of inferior materials and exposure to aggressive en-vironment. The need for a repair is primarily dic-tated by the severity of the deterioration as de-termined from the diagnosis. Good workmanship is essential if any thing more than just a cosmetic treatment to the creation is required.1. performance requirements of repair systemHaving established the causes of the defect by carefully diagnosing the distress, the next step should be to consider the requirements of the re-pair method that will offer an effective solution to the problem (see fig.).①DurabilityIt is important to select repair materials that provide adequate durability. Materials used for the repair job should be at least as durable as the substrate concrete to which it is applied.②Protection of steelThe mechanism of protection provided to the reinforcing depends on the type of repair ma-terials used. For example, cementations materials can protect the steel from further corrosion by their inhibitive effect of increasing the alkalinity of the concrete, whereas epoxy resin mortars can give protection against the ingress of oxygen,moisture and other harmful agents.③Bond with substrateThe bond with the substrate must produce an integral repair to prevent entry of moisture and atmospheric gases at the interface. With most re-pair materials, the bond is greatly enhanced with the use of a suitable bonding aid such as an un-filled epoxy resin systems and slurry of Portland cement, plus any latex additives for a Portland cement-based repair system. Precautions should also be takento remove all loose and friable ma-terials from the surfaces to be bonded.④Dimensional StabilityShrinkage of materials during curing should be kept to a minimum. Subsequent dimensional change should be very close in the substrate in order to prevent failure⑤Initial Resistance to Environmentally In-duced DamageSome initial exposure conditions may lead to premature damage lo repairs. For example, partially cured Portland cement repairs can dete-riorate from hot weather preventing full hydration of the cement. To prevent this from happening extra protection during curing time may be nec-essary.⑥Ease of ApplicationMaterials should be easily mixed and ap-plied so that they can be worked readily into small crevices and voids. Ideally, the material should not stick to tools, and should not shear while being trowel led nor slump after placement.⑦AppearanceThe degree to which the repair material should match the existing concrete will depend on the use of the structure and the client' s re-quirements. A surface coating may be required when appearance is important or when cover to reinforcement is small.2. Selection of Repair MethodsA suitable repair counteracts all the defi-ciencies which are relevant to the use of the structure.The selection of tile correct method and material for a particular, application requires careful consideration, whether to meet special requirements for placing strength, durability or other short-or long-term properties. These con-siderations include:1. Nature of the DistressIf alive crack is filled with a rigid material, then either the repair material will eventually fail or some new cracking will occur adjacent to the original crack. Repairs to live cracks must either use flexible materials to accommodate move-ments or else steps must be taken prior to the re-pair to eliminate the movement.2. Position of the CrackTechniques which rely on gravity to intro-duce the material into the crack are more suc-cessfully carried out on horizontal surfaces but are rarely effective on vertical ones.3. EnvironmentIf moisture, water or contaminants are found in the crack, then it is necessary to rectify the leaks Repair to slop leaks may be further com-plicated by the need to make the repairs while the structure is in service and the environment is damp.4. WorkmanshipThe skill the operatives available to carry put the repairs is another relevant factors. Some-times this can mean the difference between a permanent repair and premature failure of the re-pair material.5. CostThe cost of repair materials is usually small compared with the costs of providing access, preparation and actual labor.6. AppearanceThe repair surface may be unsightly, par-ticularly when it appears on a prominent part of the building. In this case, the repair system will include some form of treatment over the entire surface.Reference[1]Philip Jodidio, Contemporary European Architecture, Taschen, Koln, pp.148-153[2]Ann Breen & Dick Rigby, Waterfronts, McGraw-Hill, Inc.

Some governments of developed countries on safe and civilized construction management and supervision ineffective, at the same time, the security incident victimscompensation is relatively low, so as to project management are real will "safety first" self psychological suggestion and safe and civilized management psychological orientation proposed higher requirements. And in the preparation of the overseas project safety assurance program, sometimes due to lack of understanding in the engineering field, easy to cause the of dangerous source judgement is not accurate or not in place, and psychologically cannot accurately to ensure the safety of the positioning of the feasibility of the program.By exploring the harmful factors in the construction process and construction process was studied in unsafe, uncivilized between factors and employee of contradiction and the law of the unity of opposites, making better use of these rules to formulate a scientific, reasonable, effective all safe and civilized production tube system, to improve and perfect the measures of safety and technological civilization, to prevent and eliminate various harmful factors in the process of construction to the conversion of the casualty of a series of management work, to protect workers' safety and health, ensure safety in production. Due to the construction of the unsafe factor is relatively more, a little careless, it may occur accident. In recent years, occurred throughout the country in the construction work accidents and serious casualty statistics tells us that construction of the security situation is still very grim. However, construction safety problems with everything else, has its own objective law. It objectively resides in the entire construction activity. Since so, naturally, be it analysis to understand, master rules of it, take the organizational and technical measures to pre control, in order to achieve the purpose of construction safety. However, there are still many problems in the management of the security civilization.Therefore, we focus on the construction stage of the construction safety civilization management, the construction of the various aspects of the construction plan, the status quo of the safety and civilization management. Through the safety awareness of the management, the system of planning, to the project safety detailed analysis of the content. There are some unpredictable problems during the process of preparation, which is the main problem in the management of safety civilization.. Lay a good foundation for further implementation.. According to the occurrence of the settlement of the accident, there is no accident occurred, record the safety civilization management improvement measures, improve the safety and civilization management. As generally work arrangements properly was period of management is relatively lax, cross process serious and complicated, and safety problems inthis period is often risks and security alert frigidity, may not out of the big problem, but small problems and small risks constantly. So strengthen safety education and training, the unknown engineering safety civilization management summary, learning.Through the research on the safety civilization management of the construction stage, the danger identification, the risk assessment and the risk control of the modern safety civilization management are discussed in three aspects.. The aim is to better and more secure the work done. Do early work after the reduction of risk, and further strengthen the construction project risk management, and thus promote the faster development of China's construction projects.2 Status quo of safety civilization managementIn recent years, with the continuous improvement of the market economy and the common improvement of people's life, construction industry has become one of the fastest developing industries. The competition of the market is increasingly fierce, so that the benefit of the enterprise to compete in the target, so to the management to benefit has become the consensus of entrepreneurs. And safety is the premise of the benefit, because the safety results determine the size of the benefit. End over the years the party and the government attaches great importance to production safety work, determine the safety production policy of "safety first, prevention first", promulgated a series of production safety laws and regulations and standards, the purpose is to protect the safety and health of laborers, control and reduce all kinds of accidents, improve the level of safety management, promote the establishment of harmonious society.The construction industry is the risk of production activities, unsafe factors, is the accident prone industry. In recent years, the death rate of China's construction industry is the highest in all industries, after the mining industry, the loss is huge, distressing. Although the mandatory implementation of the construction enterprise safety production license system, strengthen the construction market access control, and to further strengthen the construction enterprise construction site safety inspections, but accidents still occur from time to time. I believe that the number of casualties mainly determined by the characteristics of the construction industry. The safety civilization management is a science, is a professional, policy, mass, and a very strong work. The safety civilization management of the enterprise is mainly embodied in the following aspects:(1) Safety awareness. Due to the leading enterprises for a long time the importance ofconstruction safety understanding does not reach the designated position, grasping safety formalism serious, disregard for workers in the production of the legitimate interests of labor and social security, is not equipped with the necessary labor protection supplies, arbitrary extension of working time, workers in the long run, the working state of the overload, high strength, will lead to accidents. In addition, the leadership of the security work seriously enough, the staff of the corresponding security awareness, it is easy to cause illegal command, illegal operations, violation of labor discipline and safety accidents caused by.(2) The weak base of security civilization management. The weak security and civilization management is mainly due to the weak safety consciousness of some people, the relationship between the safety and the speed, safety and the relationship between safety and benefit, security and stability.. The weak safety management is mainly reflected in the weak: first, the research work of building safety technology is weak, and the key technology of building safety production is relatively lagging behind. The wide application of safety scientific and technological achievements is lack of market-oriented policy guidance and economic incentive measures. Study on the construction of new technology, new products, new technology application and safety protection measures of synchronization; second, compared with the developed countries, our country security protection technology, protective equipment and machinery and equipment is still relatively backward. Standardization, stereotypes and industrialization degree is very low; three is the construction enterprise safety civilization management and construction team quality is generally low. The safety of the low quality of the cultural quality, safety and civilization management knowledge, safety and technical specifications, safety procedures, safety precautions and so on do not understand. Can't manage the construction team.(3) The construction safety laws and regulations system is not perfect. There are some limitations to implement its security responsibilities; terms of punishment for violations of the law is not specific enough, operability is not strong; laws and regulations are not perfect, there is a problem of duplication and overlapping management; safety rules and regulations of the responsibility is not clear, management objectives is not clear, resulting in production safety responsibility of implementation is not in place etc..(4) The mechanism of the construction safety supervision and production is not perfect. At present, the mechanism of the effective construction safety supervision and management inChina has not been formed, and there is a big gap compared with the international advanced security management mode.. The safety supervision mode and management means can't adapt to the growing scale of construction, and it is difficult to carry out the construction safety supervision work further.. Mainly in the following three aspects:Construction unit safety civilization management problemThe exploration, design, construction and supervision of the construction engineering to the entity or individual contractor who is not qualified or qualified or even illegal. Due to the layers of subcontracting, resulting in the construction management is not strict, security training is not in place and security investment or basic no. And it will also make lower profits, and contractors in order to pursue the maximal profit will reduce his all unnecessary amount of spending, leading to safety hazards and accidents continue to occur.Investigation, design, engineering supervision and other units of the major security issuesSurvey, design units not in accordance with the requirements were survey or design, or change the survey and design documents, laws, regulations and mandatory standards, to survey the design defects, can not guarantee the building and construction personnel safety engineering supervision units not to the construction unit safety technical measures or special construction safety program for careful review, in the engineering construction nor of construction units to implement security measures of supervision seriously, find the hidden accident, nor does it take decisive measures to be rectification and elimination; detection unit to produce a false report.Safety problem of construction unitWith the increasing investment in infrastructure, the construction enterprise access policy adjustment, making the number of construction enterprises continues to increase, the construction team continues to expand. Especially in recent years, the rapid development of individual construction industry, the construction enterprise has changed fundamentally. But because the construction unit is the main body and the core position in the construction safety activity, the construction safety problem is mainly in the construction unit body.2.1 Government laws and regulations(1) The lack of building safety and civilization management system for the market economyConstruction of China's investment system changes the original building a safe and civilized production management has not adapt to the current construction methods, so has been dominated by the government of safe and civilized management appeared many loopholes in management, coupled with the construction safety laws and regulations is not perfect, the low efficiency of government supervision, social supervision system is not perfect, resulting in a safe and civilized management is not in place, suited to the laws of market economy, legal and economic means parallel building a safe and civilized management system has not been formed. Therefore, the initiative construction safety civilization management initiative construction safety civilization management work first, early planning, early arrangement, do the whole process supervision and inspection. Before the construction we put the project in the province Shuangyou site as the target management, improving the safety management measures and system in the project, accomplish beforehand to prevent. Employees entering the construction site, the first production safety education and follow the operating rules of education; followed by a safety technical disclosure and each segment and sub engineering safety technical disclosure, so that all staff familiar with the rules and regulations, consciously abide by the safety regulations and operating rules, improve the sense of self-protection. Strengthen the intensity and extent of the supervision of the safety and civilization management objectives for effective control.(2) The law and regulations are more and more incomplete and the execution is not enoughOur country law "environment and health" is too weak. The emphasis on "environment and health" in the activity of architecture has become a common topic of international concern. The target system of engineering construction has been shifted from the traditional "cost - cost - quality - time - to - Project" system to "cost - quality - time - environment and health" system.. The international standard organization has also developed the environmental management system.(3) The functional changes of the management department are lagging behind and the management of the vacuum isWith the deepening of the reform of our political system, the reform of the national institution, the enterprise reform, the enterprise has gradually separated from the industry administrative management, and has become the independent action subject in the market.With this adaptation, Ministry of construction and local construction administrative departments to become the national construction safety special supervision of the performer, state production safety supervision and administration and the local production safety supervision and management institutions become discharger of the state production safety supervision functions.The unsafe state of the unsafe behavior and the unsafe state of the material are the direct cause of the accident, which are directly related to the management. So the management is the indirect cause of the accident.. The unsafe behavior of human can be reduced or even eliminated through safety education, safety production responsibility system and security mechanism. The unsafe state of the material can be controlled by improving the scientific and technological content of the safety, establishing the perfect equipment maintenance system, promoting the construction and safety of the civilization. To strengthen the safety inspection on the job site, we can find and stop the unsafe behavior and the unsafe state of the thing, so as to avoid the accident. One of the most common defect management system is not perfect, the responsibility is not clear, abiding by the law, the illegal command, safety education is not enough, punishment is not strict, safety technical measures are not comprehensive, security check enough.(4) The construction safety production management and professional construction safety production management separateAt present, China's construction safety civilization management is actually decentralized management, did not really do the industry management. This has formed the construction safety civilization management standard, the management pattern is different, the casualty statistics data distortion, the management work responsibility is not clear.Pay attention to safety behavior norms according to the laws of science organization construction, comply with construction safety rules and standards, as a code of conduct to organize the construction of construction site to be constrained, regulate their behavior from two aspects: one is to require managers to strictly implement the construction administrative departments of the state and local issued by the construction safety and civilized management regulations and standards the implementation of the management system of the enterprise, before the construction of the relevant technical requirements for the construction safety to the crew and workers in detail, and signed by both parties confirmed that security staff dailyinspections of implementation; two is to require the operation layer; safety protection for the outstanding construction site could cause accident.2.2 The characteristics of the construction safety civilization managementThe characteristics of construction are mainly determined by the characteristics of architectural products. Compared with other industrial products, building products is huge in size, complexity and diversity, overall hard, not easy to mobile, so that construction in addition to the basic characteristics of industrial production, but also has the following main features:(1) The fluidity of productionOne is the body construction with the buildings or structures located position change and the transfer of production sites; the second is in the process of the construction of a project construction personnel and all kinds of machinery, electrical equipment with the construction site and along the construction of the object up, down, left and right flow, continue to turn shift operation places.(2) The product form is diverseDue to the natural conditions and uses of the building, the structure, modeling and material of the building are also different, and the construction method will be changed, it is difficult to realize the standardization.(3) Construction technology complexConstruction often need according to the structure of the building for many types of work with the operation, multi unit (earthwork, civil engineering, hoisting, installation, transportation, etc.) cross tie construction, the supplies and equipment are different, thus the construction organization and construction technology management has a higher request. Most of the construction industry is still manual operation, easy to make people fatigue, attention dispersion, so improper operation or mistakes more prone to occur, Rong Yi lead to accidents security. This is manual labor and heavy manual labor and more.(4) Open and aloft operationsThe building product is huge, the production cycle is long, the construction is carried on frequently in the open air and the high place, is often influenced by the natural climate condition. According to the national standard "high job classification" provides that there are more than 90% of the construction of higher operations. The open operation of buildingsaccounts for about 70% of the total workload, and the impacts and hazards of natural conditions such as spring, summer, autumn and winter, and sunshine, wind, rain, snow and snow etc.(5) Low mechanizationAt present, the construction mechanization degree of our country is still very low, still depend on a lot of manual operation.. Construction machinery and machinery in the factory compared to the mechanical equipment is very different, its safety is much higher than the factory equipment, the probability of injury is naturally much higher. There are several aspects of the following features:A. Use of different environmental conditions;B. Operating object is different;C. Operating location and operator;Take the crane as an example to discuss the mechanization of safety civilization management.In our country, with the increase of the number of the heavy machinery, the proportion of the injury accidents in the total industrial accidents is also increasing year by year. The common accidents of hoisting machinery are: the hanging falls, the impact of extrusion, the accident, the electric shock accident, the body dump accident.. The total number of crane crashes accounted for about 33%, the impact of extrusion accounted for about 30%, electric shock accounted for about 10%, the accident accounted for about 8%, the body dumping accounts for about 5%. The total number of the total number of injuries from the accident of the highest percentage of falling accident analysis:A. Off the rope accidents: due to the load from a bundle of the hoisting rope shedding collapsibility casualties damage.B.Weight loss accident from heavy lifting rope or special sling from hook caused by prolapse.C. Broken rope accident: hoisting rope and hoisting rope broken down due to the weight loss accident.D. Hook broken accident: weight loss accident fracture caused by hook.E. Hoisting wire rope problem.2.3 The work content of the construction safety civilization managementConstruction enterprises to do a good job security construction should pay attention to do the following several work:(1)Thinking;(2) Establishment of a safety production management system;(3) Establishing the safety and professional bodies and with full-time safety technicians;(4) Ensure that the workers are safe and secure;(5) Take the targeted safety measures;Safety technical measures should be aimed at the engineering features, in depth investigation and study. Also do a good job of work safety technical disclosure.3 Security checkThe security check is found in time, eliminate hidden dangers of accidents, an effective way to nip in the bud. The construction product volume is huge, the height operation is high, and then combined with the construction period, the technology complex and other factors, to the construction production brings a lot of unsafe factors. Through the combination of leadership and mass security checks, can effectively find the problem, take measures to eliminate the accident before the occurrence of the accident. Safety inspection can also summarize the good experience of the exchange of safety production, establish a typical, to promote the level of safety and civilization management. Mobilize the masses for security checks, both to encourage the masses to participate in the enthusiasm of safety and civilization management, and can educate the masses to enhance awareness of the safety awareness of production, and consciously improve the safety of production. In addition, the safety inspection can often give the neglect of the safety of the idea of knocking the alarm, and promptly correct illegal command, illegal operations behavior.4 SummarySafety civilization management is a science, is a professional, policy, mass, and a very strong work. With the continuous development of the economy, the continuous improvement of people's living standards, employees in the construction industry and the whole society are on the construction process of safe and civilized management level proposed requirements more and more high, the traditional management mode has not adapted to the requirements of the times. It is now in need of scientific and modern enterprise security and civilization management mode, and continuously improve the level of safety civilization management, thereal safety civilization management work well. The scientific use of PDCA circulation method, the pair of leaders of all levels of safety education and construction plan possible accident, the implementation of safe and civilized management plan, make safe and civilized management is better in the construction of perfect embodiment. To inspect the construction process of the construction management plan, and find the problem that hidden and haven't met to solve, analyze and record, and put the security plan into the program. To reach a circular process. Therefore, as the construction enterprise, we should study the status quo of the construction industry safety civilization, establish the new idea of safety civilization management, and establish new accord with the.Construction safety management civilization is the first human management, to strengthen the safety education and training, continuously improve the quality of security business, enhance security awareness, and to take effective measures to regulate people's behavior, to implement standardized operation, in construction process due to the complexity of the construction site personnel, dynamic and frequent, in project management, to take admission to tertiary education and the change of production and construction, timely safety education; combination of production safety skills training, in order to enhance staff safety consciousness of responsibility and security capabilities.Through the safety civilization management education and training, strengthen the construction safety and the implementation of the guarantee. Safety education is the most effective method in the safety civilization management. Both time and greatly reduce the cost. On the construction enterprise personnel, from the leadership to the construction workers are admitted to the education and training, the whole aspect to strengthen safety awareness. A clear division of labor and management, the construction project without mistake, reduce the mistake. Building a safe and civilized management is a very complex system engineering, we must use of scientific management methods, management methods, the establishment of new safe and civilized management mode to improve worker safety execution. Only in this way, we can really make a safe and civilized management level to a new level.施工阶段的安全文明管理1.研究内容与目的目前我国的安全生产形势依然严峻，特别是建筑领域伤亡事故多发的状况尚未根本扭转，建筑施工安全极其严竣；安全生产基础比较薄弱，保障体系和机制不健全；安全生产监督管理机构、队伍建设以及监管工作还待加强。

外文文献：Project portfolio management –There’s more to it thanwhat management enactsAbstractAlthough companies manage project portfolios concordantly with project portfolio theory, they may experience problems in the form of delayed projects, resource struggles, stress, and a lack of overview. Based on a research project compromised of 128 in-depth interviews in 30 companies, we propose that a key reason why companies do not do well in relation to project portfolio management (PPM) is that PPM often only covers a subset of on-going projects, while projects that are not subject to PPM tie up resources that initially were dedicated to PPM projects. We address and discuss the dilemma of wanting to include all projects in PPM, and aiming at keeping the resource and cognitive burden of doing PPM at a reasonable level.Keywords：Managing programmes，Managing projects，Organisation resources，Strategy1.IntroductionAt any given point in time, most companies engage in many projects. Some of these projects may relate to product development and marketing, others relate to changes in work processes and production flows, while yet others relate to competency development, strategic turns, the implementation of new IT systems, environmental issues etc.A key managerial task is to dedicate resources across all of these projects (as well as do daily work) and consequently,management across projects (project portfolio management (PPM)) is critical to company performance.This paper is based on a large-scale qualitative study,which shows that many project-oriented companies do not perform well when it comes to PPM. This relates to the inability to accomplish projects that are initiated. In particular, we identify the following problems:(1) Projects are not completed according to plan (or they even peter out during their project life cycle);(2) Management and employees feel they lack a broad overview of on-going projects (especially when the number of on-going projects increases as more and more projects are not completedaccording to plan);(3)People experience stress as resources are continuously reallocated across projects in order to make ends meet.These observations are especially interesting because the companies were included in the research project because they were supposed to be especially,experienced in PPM, and because they actually engage in PPM according to the extant body of literature on PPM. For example, part of the companies‘ PPM included an effort to pick the best projects on the basis of explicit or implicit criteria, and an effort to allocate sufficient resources to these projects.However, despite efforts,to practice ‗good‘ PPM, these companies experience severe problems in relation to PPM – especially in letting enough resources go into the ‗right‘ pr ojects. The purpose of this paper is to confront PPM as advocated by normative theories with actual PPM practices. Hence, the purpose is to confront PPM theories with PPM as perceived by managers and other employees for whom PPM is part of, or affects, their work conditions.However, in this paper, we are more interested in PPM as enacted by companies than in universally true perceptions. Hence, we adhere to Weick‘s [1–3] notion of enactment as the preconceptions that are used to set aside a portion of the field of experience for further attention. In regard to PPM, enacted projects are thus the ones management sets aside for further attention (i.e. PPM). As such, we focus especially on ways actors define or enact projects [4] and make sense of how to manage the sum of the projects. Drawing on this perspective, we account for findings that suggest why companies that do engage in PPM still experience problems.2. Project portfolio theoryThis paper draws on Archer and Ghasemzadeh‘s [5, p.208] definition of p roject portfolios as ‗‗a group of projects that are carried out under the sponsorship and/or management of a particular organization‘‘. Henceforth, we define PPM as the managerial activities that relate to(1) the initial screening, selection and prioritisation of project proposals,(2) the concurrent reprioritisation of projects in the portfolio,(3) the allocation and reallocation of resources to projects according to priority.For quite some time researchers have suggested that low completion rates for new product development (NPD) projects and new product failure relate to resource deficiencies in key areas [6,7]. Furthermore, while a host of researchers [8–10] have focused on the dimension of PPM that concernsprocesses relating to selection of projects to be included in the portfolio, research e.g. [11] also increasingly focuses on the day-today management of the project portfolio.3. MethodologyOver a period of two years, we did empirical research on how companies manage their entire range of projects, e.g. renewal projects, strategic projects, IT projects, departmentally specific projects, and production based projects. In relation to the selection of companies to be included in the empirical study, a key criterion was that the study should cover a wide variety of industries. As a result, the empirical study covers 30 companies from industries as diverse as, e.g. mobile telephone communications, finances, energy, pharmaceuticals, toys, software, and foods.However, due to the fact that we were looking for companies, where the amount of on-going projects suggested they were engaged in PPM, the study is biased towards larger companies as well as companies that define at least a substantial part of their activities as projects. The degree to which the companies participated in the study varies. Hence, half of the companies are labelled ‗inner circle‘ companies due to the fact that we drew extensively on these 15 companies. For example, in these companies more interviews were conducted at various points in time and at various organizational levels. Hence, a longitudinal perspective characterizes the involvement of these companies.The remaining half of the companies are labelled ‗outer circle‘ companies because their participation in the study has included fewer top-management interviews, the purpose of which was to gain insight into ways in which (top) management defines the content of their project portfolios and manages them.4. Managerial implicationsA key finding is that the gap between required and available resources is very much attributable to the existence of a host of smaller projects that never become part of enacted project portfolios. Thus, at an aggregated level, the empirical study suggests smaller, un-enacted projects qualify as resources crunchers in so far they are not considered to be a part of enacted project portfolios. In order to overcome this crunch in resources, two solutions seem obvious:(1) Enacting more, i.e. having PPM embrace all projects.(2) Allocating more resources to a pool of loosely-controlled resources for the un-enacted projects to draw on.5. Research implicationsThe empirical study elaborates on the ‗‗significant shortage of resources devoted to NPD‘‘ that Cooper and Edgett argue is the fundamental problem ‗‗that p lagues most firms‘ product development efforts‘‘.Our work especially suggests that the shortage of resources devoted to enacted projects is not a problem that primarily arises in relation to top management‘s PPM. On the contrary, in-good-faith top management dedicates resources to enacted projects on the basis of sound PPM. However, what top managers do not do is take into account the host of smaller projects that individuals initiate and – more importantly – top managers ignore (or at least heavily under-estimate) the amount of resources that these smaller projects tie up. Hence, we argue that especially the crunch in resources may be attributable to the un-enacted competition for resources that smaller projects subject enacted projects to.Consequently, the key contribution of our empirical work to research is that it emphasises that if we wish to study PPM (and especially if we wish to relate PPM to project performance), we might be better off taking into account the entire range of projects that actual (not enacted) portfolios are comprised of. Thus, if we as researchers only enact the projects that are neatly listed by top management, then our research will neglect the host of projects that are not subject to PPM, projects that nonetheless take up valuable, and scarce, resources.The fact that the empirical study includes interviews with managers, i.e. those who do PPM, and interviews with personnel at lower organisational levels, i.e. those whose work is subject to PPM, is the reason why we were able to identify un-enacted projects. Thus, researchers interested in PPM should be careful not to rely too heavily on a management perspective.6. Conclusion and limitationsThe main conclusion is that as long as some projects are un-enacted, companies may experience a drain on resources that reduces the time and resources actually devoted to projects subject to PPM. Hence, each individual company should decide whether or not all projects should be part of PPM and if the end result of such a decision is not to make comprehensive project lists (i.e. lists that include all minor projects), then management should decide how many resources should be set aside for the plethora of small projects that do not appear on the project list.One way in which the crunch in resources can be reduced is by ensuring that smaller projects do not take up a critical portion of the resources that are – officially – set aside for the completion ofprojects subject to PPM. However, due to the exploratory nature of the study accounted for in this paper, our findings relate far more to what companies actually do (positive theory in Hunt‘s terms), rather than to what they ought to do (normative theory in Hunt‘s terms). Although generating positive theory is indeed a crucial first step – especially in relation to the future of PPM theory –positive theory cannot, and should not, stand alone. Hence, the key challenges for PPM theory in the future are to produce normative theory that offers sound suggestions as to how companies can improve their PPM.Another limitation of our study is that the empirical part was carried out in a Danish context as the 30 companies involved are located in Denmark, which may not be sufficiently representative for companies worldwide because Denmark has, to a larger extent, a bottom-up culture. Therefore, the portion of smaller un-enacted projects may be bigger here than in companies in other countries. We hope that our study will inspire other researchers to carry our similar studies in other countries.References[1] Aboloafia MY, Killduff D.

With increasingly fierce market competition, the quality of work and the construction of civilizations rising material prices fluctuations. uncertainties and other factors, make the project operational in a relatively tough environment. So the cost of control is through the building of the project since the bidding phase of acceptance until the completion of the entire process, It is a comprehensive enterprise cost management an important part, we must organize and control measures in height to the attention witha view to improving the economic efficiency of enterprises to achieve the purpose.2 Outlining the construction project cost controlThe cost of the project refers to the cost and process of formation occurred, on the production and operation of the amount of human resources, material resources and expenses, guidance, supervision, regulation and restrictions, in a timely manner to prevent, detect and correct errors in order to control costs in all project costs within the intended target. to guarantee the production and operation of enterprises benefits.3 The cost of the construction enterprise principles of construction enterprises controlThe cost of control is based on cost control of construction project for the center, Construction of the project cost control principle is the enterprise cost management infrastructure and the core, Construction Project Manager in the Ministry of Construction of the project cost control process, we must adhere to the following basic principles.1）Principles lowest cost. Construction of the project cost control, the basic purpose is to cost management through various means, promote construction projects continue to reduce costs, to achieve the lowest possible cost of the objective requirements. The implementation of the principle of minimum cost, attention should be given to the possibility of reducing costs and reasonable cost of the minimum. While various mining capacity to reduce costs so that possibility into reality; The other must proceed from actual conditions, enacted subjective efforts could achieve a reasonable level of the minimum cost.2）Overall cost control principles. Cost Management is a comprehensive enterprise-wide, and full management of the entire process, also known as the "three" of management. The full project cost control is a system of substantive content, including the departments, the responsibility for the network and team economic accounting, and so on, to prevent the cost control is everybody's responsibility, regardless of everyone. Project cost of the entire process control requirements to control its costs with the progress of construction projects in various stages of continuous, neither overlooked nor time when, should enable construction projects throughout costs under effective control.3）Dynamic Control principle. Construction of the project is a one-time, cost control should emphasize control of the project in the middle, that is, dynamic control. Construction preparation stage because the cost is under the control of construction design to determine the specific content of the cost, prepare cost plans, the development of a cost-control program for the future cost control ready. And thecompletion of phase cost control, as a result of cost financing has been basically a foregone conclusion, even if the deviation has been too late to rectify.4）Principle of management by objectives. Management objectives include : setting goals and decomposition, the goal of responsibility and implementation of the aims of the inspection results of the implementation, evaluation of the goals and objectives that form the management objectives of the planning, implementation, inspection, processing cycle, PDCA.5）Responsibility, authority, in light of the profit principle. Construction of the project, project manager of the department, the team shouldering the responsibility for cost control at the same time, enjoy the power of cost control, project manager for the department, Teams cost control in the performance of regular examination and appraisal of implementation of a crossword punishment. Only to do a good job duties, rights, and interests combining cost control, in order to achieve the desired results.4 The construction cost control measuresProject Manager of the project cost management responsibility for the first, comprehensive organization of the project cost management, timely understand and analyze profit and loss situation and take prompt and effective measures; engineering technology department should ensure the quality, Regular tasks to complete as much as possible under the premise adopt advanced technology in order to reduce costs; Ministry of Economic Affairs should strengthen budget management contract, the project to create the budget revenue; Finance Ministry in charge of the project's financial, Analysis of the project should keep the financial accounts of reasonable scheduling of funds.Develop advanced economies reasonable construction program, which can shorten the period, and improve quality, reduce costs purpose; paid attention to quality control to eliminate redone, shorten the acceptance and reduce expenses; control labor costs, material costs, Machinery and other indirect costs.5 Strengthen project cost control practical significance1）Strengthen project cost control railway construction enterprises out of their predicament, the need to increase revenue. At present, the railway construction enterprises just into the market, to participate in market competition, will face a tough test of the market. Now the construction market liberalization, implement bidding system, and the strike has very low weight, To create efficiency is the only way to strengthen internal management and improve their internal conditions, internal efficiency potentials. Therefore, the strengthening of project cost control is a very realistic way.2）Strengthening Project Cost control is adapt to the market competition, and strengthening internal management to the needs of their work. With the railway enterprise's rapid development, construction increasingly fierce market competition. For a period of time, the railway construction enterprises will face the increasingly fierce market challenges Construction of the business environment difficult to be improved. Efficiency increases, effective cost control and claims will be strengthened in the future management focus. This requires the railway construction enterprises should respect the unity of the work to reduce costs and enhance efficiency objectives.6 Currently construction enterprise project cost control analysis of the current project cost6.1 Problems and the causes of the current project implementationIn summary, the current project of cost management, accounting only after the accounting, rather than advance the prevention and control things. The reasons are : lack of cost awareness. simply that the cost of management is the financial sector or the superior leadership, have nothing to do with them. only focused on the "production tasks are completed" and "contracting profit and loss," the groups have a "negative effect." Therefore, project to mobilize the full participation of the Ministry of cost control, deepening of the project cost management imperative.6.2 Project Department analysis of the reasons for the losses as a project of building productsCommodities direct producers, both under the contract and construction drawings, self-regulating organizations of the construction authority, but also by contracting, design, Enterprises and other projects related to the construction of the units affected and constrained. In addition, geological and climate changes, Design changes, but on objective factors of the construction projects have a significant impact, and all of the above factors will affect the cost of project expenditures.6.2.1 Lost control of the cost of the so-called subjective reasons,Subjective reasons refer to the project, can not dispose of any external influence on the control of the costs, As mentioned above the project with the Ministry of Construction for the autonomy of the cost. mainly include the following aspects :1）No strict cost control of the overall goal or no cost control goals. Most of the loss items Department head, there is no cost control goals. Although some but not strictly enforced, thus the cost of the project is out of control.2）Materials, spare parts planning, procurement, inspection, custody, out of the reservoir, consumption of the system is not sound. the loss of the item, the purchase of materials and accessories unplanned phenomenon abound. procurement lies in the number of project managers even material, the result is bound to lead to a backlog of material, cost overruns.3）Serious quality problems. serious losses Project Department, almost all relatively serious quality problems, resulting in rework, repair, It seems a repetition of construction, increase the costs of construction. For example, in the bridge construction, there is the basis sank, Pier deflect such phenomena.4）Unreasonable arrangements. During the construction process, the project was not in a reasonable allocation of manpower, materials, equipment and other resources. lead to a waste of sabotage work; Construction of the manufacturing arrangements unreasonable to step in to complete the actual conduct of the second, three complete, the resulting redone, and so on.5）More accidents. the loss of the item, Most of the projects have occurred in the Department of varying degrees of security incidents and minor injuries affected employees work injuries have affected staff work, Also the cost of medical expenses, but can also enable the staff of physical and skills decline, reduced labor and labor efficiency; fatal accidents resulting in huge pension costs to be incurred, directly increasing costs, and may also affect sentiment reduce production efficiency.6）Contract management confusion. the loss of the item, Most of the projects the Ministry failed contract management awareness, knowledge of the contract, and have little do not understand the basic elements of the contract, contract management led to confusion, enterprises suffered huge economic losses.6.2.2 The influence of objective factors of the project is to increase the total cost of a connection so-called objective factorsProject Department is unable to control its own and must take place or because there are things or phenomena, such as contracting, design, enterprises in terms of the contract for the project outside the Ministry of Construction issued the directive, geological and climate changes, Design changes such. These factors for the emergence of the cost incurred, Project Department is not the objective to control costs. These factors are :1）Costs. Some enterprises in order to gain access to a particular market in the qualifications, thereby meeting the quality of construction projects built on the premise that right to take the tender bid price is lower than the cost of bidding strategy for the final bidding process, in the operating strategy is bound to happen, but projects are concerned, no matter what steps are taken it will be difficult to make these projects profitable.2）Geological and Climate changes. the geological conditions are inconsistent with the design, Projects will be forced to change the construction method, thus affecting the construction period, so that the total project costs. the same time will also cost breakdown of a larger change. Winter, Construction of the rainy season andthe number of days of sandstorms construction increase, the Ministry will allow the project to increase various fees.3）Design changes. various engineering design changes so that the project will cost changes affect the total project cost. For example, contracting unit to increase the number of extend or shorten the construction period. changes in construction plans and projects to improve the quality of grading, etc..4）Construction design less reasonable. As a construction site with the actual difference individual projects in construction design at the time of the existence of irrational phenomena, such as the personnel, materials, equipment arrangements and plans for the accuracy of individual projects or processes of the time, the lack of quality considerations. Projects can make the cost increase.5）Sabotage work of the project. As work on the link between tasks or for other reasons, Projects have some sabotage work, in this period sabotage work needed to meet various costs, such as wages or basic living expenses. fixed asset depreciation charges, indirect costs of the project. Projects6.3 Containment measures for the lossContainment measures for the loss of containment for a variety of reasons over the project losses, in accordance with the requirements of clear responsibilities, Projects should control the cost of the project is able to cost control measures were taken. for a project to control the cost of the project by the Ministry of control; and the project beyond the control of the costs or losses, by the enterprises should take measures to control it.6.3.1 Construction projects to the Ministry of the so-called cost control measures to the Ministry of Construction of the project.Construction projects to the Ministry of the so-called cost control measures to the Ministry of Construction of the project.refer to enterprises directly organized by the staff and farmers contract workers, temporary workers and the labor force composedof the internal construction team, mixed construction team and construction services sub-teams composed of Construction Projects.1）Determine the total project cost targets and the profit and loss targets. Every one of the successful projects, in a formal pre-construction, identify the project and sub-project for the dates, materials, equipment and identify the project and sub-project of the labor, materials, machinery and indirect costs. On this basis, The project will determine the profit or loss targets.2）Implemented material bidding procurement. Projects must thoroughly change the past, piecemeal purchase goods, the enterprises of all projects, including the main material to build on all the tender for the procurement, Obviously choice of material suppliers. Meanwhile, we should fully consider the time value of money. choose a suitable form of payment.3）Controllable according to the principle of cost control. The Ministry of Construction of the project team and staff, In accordance with the principle of cost control and distinguish the project department, the construction team and the staff of the costs of monovalent responsibility, including dates Price, Materials Unit, select the unit and units, or fixed rates. We must strictly enforce the internal inspection system for pricing, timely construction team and staff honored economic interests.4）Enhance safety, and quality management. Projects must establish security, Quality is the major benefits of efficiency. actively prevent and avoid possible security, quality accidents, for the accident-prone regions of constant surveillance. to strictly implement the responsibility for the accident the penalty system so that all staff clearly establish the safety, quality consciousness.5）Strengthen contract management. All of the projects, In particular, the main sub-projects of the need for a designated person responsible for contract management, In addition to the timely settlement or deal with the things, with the other units or individuals from the economic, technical, labor matters, must sign the formal contract, not with the verbal agreement. at the contract process, should act in strict accordance with the relevant provisions of the contract for disposal.6）Improve the management system, establish a cost-control mechanism. Projects must connect with reality, the development and control of the cost to draw up rules and regulations, such as material procurement, custody, inspection, warehousing, consumption system, the labor remuneration management systems, equipment management, financial management, accounting, security, quality management approach, the post-mortem valuation methods, and to establish the cost of the project department of internal control and supervision mechanisms.6.3.2 Construction of the sub-item of cost control measures in the so-called sub-Construction Projects1）Determined in accordance with the assembly The objectives of the sub-projects to determine the price.2）Allocated in strict accordance with the requirements of the project and the clearing. Projects must be in accordance with the provisions of the contract settlement price of the project, completion of the sub-units of qualified engineering post-mortem will be conducted on a monthly basis for the valuation and then clearing projects, sub-units will not be allowed to advance baiting, and for projects.3）Strictly prohibited construction of external units link . Projects must be in accordance with the requirements of enterprises, prohibit external units linked to various forms of external construction enterprises. Any item shall not allow the Ministry of External units to enterprises in the name of contractor carry out projects, the post-mortem pricing and settlement payments.7 On how to conduct effective cost control7.1 Segmentation project costOptimal allocation of project resources project allocation of resources is directly related to cost control methods and extent of For many of the ongoing state-controlled construction of large enterprises, Basically, the cost of the project is a subcontractor costs and cost of the construction team, and the enterprises is the main source of economic control subcontractor costs. Team Construction costs are often difficult tocreate cost-effective. both how the mix, the cost of the project into how, This enterprise is the key to cost control problems.7.2 The development of a cost planA cost of the complete dynamic control costs and responsibilities of sub-division and the initial cost of the two identified some of the costs, To work out the total cost of the scheme, the total cost of the scheme is in addition to covering the costs and responsibilities of sub-cost, should also consider funding the project site, the higher management fees, taxes and other factors. The total cost will be divided into two parts :1）Uncontrollable cost of the project : it refers to taxes, the higher management fees can not be subjective project management control;2）Controllable cost of the project : the total cost of the scheme, apart from the uncontrollable costs other than the full cost, such as subcontracting costs, responsibility for the cost, on-site expenses.Controllable costs are focused on cost control, controllable cost of the project is planned prior to the commencement of the construction time, construction, construction design based on. Along with the progress of works and that will happen if the construction program improvement works to change, to build factors such as rising price changes. So for the cost of plans to conduct timely adjustment, the cost of the scheme is to ensure that the guidance and control, in the adjustment should pay more attention to analysis of the different factors changes to the original cost of the scheme is the extent of the effect.7.4 Conduct a cost analysis, improve enterprise cost management level after the end of constructionAccording to the total cost of the scheme and controllable cost plan and the final actual cost comparison analysis, cost analysis charts available in various forms, such as comparative analysis not only to the total cost, but also to process cost analysis, but mainly to process analysis, process reached higher or lower cost reasons.1）First analyze the conditions for the construction, Construction programs, materials price changes caused by changes in the unit price for the process, collecting the introduction of new technology, new techniques, and new materials processes cost information;2）Followed by the subjective determination of the cost comparison part of the process the price analysis by the enactment of the unreasonable result of the high or low price processes, while accumulation of written information, for the future development of similar projects the cost of the scheme;3）Sub-units of information collection and evaluation of sub-contractors, prepared, "the roster of qualified sub-contractors" for future similar projects to choose subcontractors and sub-development costs;4）Summary subcontracting costs and responsibility cost data, after screening analysis for enterprise Bidding reference.8. Summary of the construction project cost controlSummary of the construction project cost control is a complicated systematic project. the application needed to be applied with flexibility the actual operation be adapted to local conditions, different sizes, different construction firms and different management systems have differences, But in any case are the construction of the production and operation of enterprises in the amount of human resources, material resources and expenses, guidance, supervision, regulation and restriction. Therefore, "increases production and economize, to increase revenues and reduce expenditures" is a common construction enterprises, This requires constant practice in the review and improve cost control, ways and means to ensure that the project cost goals.施工项目的成本控制1 引言项目是企业的形象窗口和效益源泉。

工程管理制度专业外文文献翻译(中英文)————————————————————————————————作者：————————————————————————————————日期：2xxxxxx 大学本科毕业设计外文翻译Project Cost Control: the Way it Works项目成本控制：它的工作方式学院（系）： xxxxxxxxxxxx专业： xxxxxxxx学生姓名： xxxxx学号： xxxxxxxxxx指导教师： xxxxxx评阅教师：完成日期：xxxx大学项目成本控制：它的工作方式在最近的一次咨询任务中，我们意识到对于整个项目成本控制体系是如何设置和应用的，仍有一些缺乏理解。
所以我们决定描述它是如何工作的。
理论上，项目成本控制不是很难跟随。
首先，建立一组参考基线。
然后，随着工作的深入，监控工作，分析研究结果，预测最终结果并比较参考基准。
如果最终的结果不令人满意，那么你要对正在进行的工作进行必要的调整，并在合适的时间间隔重复。
如果最终的结果确实不符合基线计划，你可能不得不改变计划。
更有可能的是，会 (或已经) 有范围变更来改变参考基线，这意味着每次出现这种情况你必须改变基线计划。
但在实践中，项目成本控制要困难得多，通过项目数量无法控制成本也证明了这一点。
正如我们将看到的，它还需要大量的工作，我们不妨从一开始启用它。
所以，要跟随项目成本控制在整个项目的生命周期。
同时，我们会利用这一机会来指出几个重要文件的适当的地方。
其中包括商业案例，请求（资本）拨款（执行），工作包和工作分解结构，项目章程(或摘要)，项目预算或成本计划、挣值和成本基线。
所有这些有助于提高这个组织的有效地控制项目成本的能力。
业务用例和应用程序(执行)的资金重要的是要注意，当负责的管理者对于项目应如何通过项目生命周期展开有很好的理解时，项目成本控制才是最有效的。
这意味着他们在主要阶段的关键决策点之间行使职责。
他们还必须识别项目风险管理的重要性，至少可以确定并计划阻止最明显的潜在风险事件。
在项目的概念阶段•每个项目始于确定的机会或需要的人。
通常是有着重要性和影响力的人，如果项目继续，这个人往往成为项目的赞助。
•确定潜在项目的适用性，大多数组织呼吁编制“商业案例”和“量级”成本，用来证明项目的价值，以便使其可以与其他所有的项目竞争。
这项工作是在项目的概念阶段进行，并且作为组织管理整个项目管理的投资组合的一部分被完成。
•准备商业案例的工作的成本通常包括企业管理开销，但是它可以作为最终项目的一个会计成本来结转。
毫无疑问，因为这将为该组织提供一个税收优惠。
问题是，那么你如何占有所有不结转的项目?•如果业务有足够的价值，将批准继续发展和定义阶段。
在项目的发展或定义阶段•开发阶段的目标是建立一个涉及到生产所需的产品，估计成本和为该项目的实际执行寻求资本融资的良好的工作的理解。
•在正式的场合，特别是在大型项目，这个拨款申请通常被称为请求(资本)拨款(RFA)或资本拨款请求(CAR)。
•这需要更详细的要求和数据的收集，建立工作所需要完成的来生产所需产品或“可交付成果”。
从这个信息来看，一个准备了足够细节的计划在一美元价格的请求上给予足够的信心。
•在一个不太正式的环境中，每个人都试图蒙混过关。
工作包和WBS项目管理计划，项目简介或项目章程•如果可交付的成果由许多不同的元素组成，这些被识别并组合成工作包(WPs)，用工作分解结构(WBS) 的方式提交。
•每个WP包括一系列的活动，“工作”被计划和安排为项目管理计划的一部分。
但是请注意，该计划仍将处于相对较高的水平，在执行期间如果项目获得批准，更详细的规划将是必须的。
•顺便说一下，这个项目管理计划应该成为项执行阶段目的“圣经”，有时它被称为“项目简介”或“项目章程”。
•然后估计各种活动的成本，这些估算成本汇总以确定WP的估计成本。
这种方法被称为“详细估算”或“自底向上的估算”。
还有其他的方法来估计，我们将在一分钟内。
不管怎样，结果是该项目的总工作的估计费用。
注:该项目风险管理规划是这次演戏的一个重要组成部分。
这应该检查项目的假设和环境条件来确定该计划中到目前为止的任何弱点，并确定值得注意缓解的这些潜在风险事件。
这可能需要特定的应急计划的形式和/或留出谨慎的资金储备。
资本要求转换估计•不过，单独的工作的估计是不能满足资本要求的。
为了达到一个资本的要求，一些转换是必要的，例如，通过添加谨慎津贴等，如开销，应急准备金来支付正常的项目风险和管理外汇储备来应付未知和可能的变化范围。
•另外，估算数据转换成财务会计的满足企业或赞助商的格式是必要的，目的是比较与其他项目和后续资金的批准。
刚才所描述的方法中，所有的数据类型为“自下而上”，在实践中可能无法使用。
在这种情况下，替代的估算方法是在时尚中通过提供不同程度的“自上而下”的可靠性。
例如：数量级估计——“球公园”估计，通常只留给概念阶段类似的估计——基于先前的类似项目的估算参数估计——基于历史数据的统计关系的估算•无论采用哪种方法，希望因此抵达总和将全额批准并被证明是令人满意的！这是触发启动项目的执行阶段注意:一些管理层将批准一些较小的总和，错误地认为这将帮助每个人“削铅笔”和“更聪明地工作”的利益组织。
这是一个错误的观念，因为管理层未能了解项目工作的不确定性和风险的性质。
因此，效果更有可能导致“切角”对产品质量产生不利影响，或减少产品范围或功能。
这通常会导致一个“游戏”的估计被放大，管理可以向下调整它们。
但公平地说，管理也清楚地意识到，如果超过分配资金，无论如何它会得到花费。
明智的管理要做的就是留出应急储备基金、不同项目的风险，并保持这些钱小心的控制之下。
核准资本的所有权•如果高级管理层批准的RFA，总和的问题变成了指定的项目发起人的责任。
然而，如果批准资本要求包括津贴如“管理储备”，这可能会或可能不会被传递给项目的赞助商，这取决于本组织的政策。
•RFA批准，项目发起人，反过来，进一步将支出权力委托给项目的项目经理，将不包括任何补贴。
一种异常可能涵盖工作表现正常变化的应急准备。
•净金额从而到达构成了项目经理的批准的项目预算。
注意:如果管理层不批准RFA，你不应该考虑这个项目的失败。
或是这个目标的目的，而规划需要重新考虑，以增加交付项目的价值。
项目的执行阶段项目经理的项目预算责任•此项目预算批准后发布的项目经理，一个逆过程必须将它转换成一个工作控制文档。
即资金必须划分在不同的WBS，顺便问一下，现在可能已经被升级。
这个结果作用于项目执行控制预算或项目基线预算，或简单地说，项目预算。
在一些项目管理的应用领域，它被称为一个项目成本计划。
•在一个大的项目中，不同的公司生产部门，可能会有进一步的中间步骤为单独的部门，创建“控制账户”，每个部门将细分他们分配资金投入自己的WBS WPS。
•观察到，因为总项目预算得到高级管理层的正式批准，你，作为项目经理，同样也必须寻求并获得执行管理，通过该项目的赞助商，正式批准任何更改总项目预算。
通常这只是合理的和接受的基础上要求的产品范围变化。
•在这种情况下项目的赞助商要么减少管理储备在他的财产，或提交补充RFA高层管理。
•现在我们项目预算资金分配给工作包，我们可以进一步分配在每个WP的各种活动，以便我们知道我们有多少钱作为“基线”为每个活动的成本。
•这为我们提供了参考的基础成本控制功能。
当然，根据情况做同样的事情可能在WP级别，但控制然后在更高的能力和粗水平。
使用挣值技术•如果我们有必要的细节另一个控制工具，我们可以采用监控正在进行的工作是“挣值”(EV)技术。
这是一个相当大的艺术和科学，你必须了解文本的主题。
•但基本上，你掌管日程安排活动的费用，并在适当的时候绘制他们作为累计。
再次，你可以做的活动水平，或整个项目的水平越低，您可用的控制信息就越多。
成本基线•这个计划参考S-曲线有时被称为“成本基线”，通常在EV的说法。
也就是说，它是“预算成本工作计划”(BCWS)，或更简单“计划价值”(PV)。
•注意到，你需要修改这个成本基线每次有一个批准范围变化，成本和/或进度影响，从而改变了该项目的核准项目预算。
•现在，随着工作的深入，你可以绘制“执行工作的实际成本”(ACWP或简单的“实际成本”-交流)。
•你可以绘制其他东西，如上面提到的图，如果你不喜欢你所看到的，你需要“纠正措施”。
注意：整个过程是一个循环，态势操作，这可能是普遍名不副实“项目的生命周期”中“循环”一词的来源”。
顺便说一句，挣值权威人士提供的EV过程中的各种其他技术设计能帮助预测最后的结果，也就是说，“估计在完成”（“选管会”）。
选管会是你真正应该感兴趣的，因为在运动项目中，它是唯一不变的。
因此，必须考虑这些延长EV技术在同一领域的自上而下的估算精度。
他们是有用的，但前提是你认识到了其局限性和知道你在做什么!但是，正如我们在开始时说的，它在实践中困难得多，需要大量的工作。
但是，让我们面对现实吧，这就是项目经理被雇佣的原因，不是吗?Project Cost Control: the Way it WorksIn 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 the Business 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.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 itCan 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 the Development Phase is to est ablish 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 fo r 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 var ious 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 total work 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 asOverheads, 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. For example:Order of Magnitude estimate – a "ball park" estimate, usually reserved for the concept phase onlyAnalogous estimate – an estimate based on previous similar projectsParametric 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 project Note: 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 resultin "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 released 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 amongst the 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 control function. 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 Work Performed" (ACWP or simply "Actual Cost" - AC).• You can plot other things as well, s ee 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 samerealm 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?。
