Planning consists of scheduling the work to be done and selecting the most suitable construction methods and equipment for the project. Execution requires the timely mobilization of all drawings, layouts, and materials on the job to prevent delays to the work. Control consists of analyzing progress and cost to ensure that the project will be done on schedule and within the estimated cost.
A sequence of construction and the time to be allotted for each item is then indicated.
The method of and the equipment to be used for the individual work items are selected to satisfy the schedule and the character of the project at the lowest possible cost.
Execution.
The speedy execution of the project requires the ready supply of all materials, equipment and labor when needed. The construction engineer is generally responsible for initiating the purchase of most construction materials and expediting their delivery to the project.
On most large projects it is necessary to design and prepare construction drawings for temporary construction facilities, such as drainage structures, access roads, office and storage buildings, formwork, and cofferdams.
Other construction engineering duties are the layout of the work by surveying methods, the preparation of detail drawings to clarify the design engineer's drawings for the construction crews, and the inspection of the work to ensure that it complies with plans and specifications.
Lesson 17
Construction Engineering
Construction engineering is a specialized branch of civil engineering concerned with the planning, execution,
and control of construction operations
Planning.
The planning phase starts with a detailed study of construction plans and specifications.
From this study a list of all items of work is prepared, and related items are then grouped together for listing on a master schedule.
The amount of time allotted for a certain
operation and the selection of methods of
operation and equipment that is readily available to the contractor.
Some materials, such as structural steel and mechanical equipment, require partial or complete fabrication by a 制作、装配 supplier. prefabricatied For these fabricated materials the engineer must prepare or check all fabrication drawings for accuracy and case of assembly and often inspect the supplier's fabrication.
After the master or general construction schedule has been drawn up, subsidiary detailed schedules or forecasts are prepared from the master schedule. These include individual schedules for procurement of material, equipment, and labor, as well as forecasts of cost and income.
