Study On The Construction Cost Determination And Control In Project Implementation Stage

The determination and control of a construction project is one of the themes of the project management. Commercialization of construction products, price determination of which should accord with market economics principle. Based on . the market economy, from the investment estimates design estimates working drawing estimate and the contract price after bid-winning of feasibility consideration stage until to stage settlement,completion settlement and final accounts of the execution phase, the control engineering cost should be executed. Systemic and process property of the control must be embodied.On the basis of fundamental theory of the construction cost determination and control, make discussion and study of the construction cost management in feasibility demonstration,design,construction each stage. According to the common phenomenon which are the losing control of construction investment and technology separation with economy, emphatically describe and analyze design and construction stage which have important significance for cost control.Based on the theory of project cost management, make use of value engineering theory and related management knowledge, analysis the conceptions the forming process of the construction project cost and contents and methods of the engineering cost management. An integrated set of controlling method and sequence is systematically designed just with the construction cost determination and control in the design stage. And quota design is reconstructed. The shortcoming of quota design is resolved by application of VE to allocation of total value of quota design. Emphasize the importance of scheme comparison in design stage, through the analysis of VE and LCC, a series of method and model on the selection of architecture scheme,structure scheme is put forward.Analysis and research on influencing factors of construction cost and main cost control measures at construction stage, generations treatment techniques and methods of contract management and altering claims are worked out.Using the construction project of participation in management myself as engineering example—expansion and reform project of Baotou station, analysis the determination of the construction cost which is from project establishment,designs construction general contracts the interior and exterior finishing bidding,contract signed to the investment estimates working drawing estimate,bidding,contract prices process pricing payments completion settlement and asset handover final account in the whole process of the concrete implementation and completion. The main influencing factors of the construction cost determination and control are worked out: project construction ranges contents scale and standards target of construction quality,depth and quality of design document,advancement and reliability of construction organization,risk events and so on. Calculate the deviation of the cost in each stage, analysis the cause, compare each subject'responsibility influenced by cost error. Then the key of engineering cost control is obtained—clarity of project range and good or bad of design quality. Technology and method of effectively controlling engineering cost are put forward through all construction process.
