| For a long time, the whole process of the engineering cost (including investment estimation, design budget, construction budget, contract price, engineering clearing, etc.) was responsible respectively by the department of investment, design and implementation. This means that it was divided in many departments and systems. Without main status of independent cost control, lack of method and application of cost control, which was the main cause of difficulty to control project cost. This paper describes the research status of engineering cost control theory at home and aboard. On the basis of the existing domestic and foreign project cost determination, control method and practical experience, the author is specification of research target key with the residential construction project of a university in Sanmenxia, studying the method of controlling the cost of the whole process. From the angle of owners(the project legal persons), in the view of construction project characteristics in different stages of investment decision, design, bidding, construction and settlement, the author combines with various cost control methods (including the investment estimate index, value engineering analysis, quota design, BOQ bidding, earned value, completion settlement audit, etc.), analyzes and applies in each stage of engineering practice, and compares with the results of application in this paper. The whole process of the construction project achieves that the design budgetary estimate does not exceed the investment estimate, the construction drawing budget does not exceed the design budgetary estimate, and the completion settlement does not exceed the construction drawing budget. The "three not" target is benefit of the school staff households. Through the research, I expect to provide some theoretical guidance and practical reference for cost control of capital construction in Colleges and universities. |
