| The investment deciding stage and project designing stage of construction have great significance as two main parts of life-cycle managemen, which have great effects on the cost control of a housing construction .However, in actual jobs, the cost control of a project's two stages doesn't get enough notice and research,which lead to the actual investment is much bigger than the expect one. This phenomena brings great pressure to the country and company's financing, and causes a capital waste.On the basis of cost control in the proposed pre-construction projects, this paper puts forward that the key phrase of cost control in the proposed pre-construction projects is the decision-making aspects and the design aspects; It overviews the methods of the feasibility study and the investment decision-making .It also brings up the countermeasures of cost control in the decision-making phase; This paper summarizes the primary means of cost control in the phase of project design, introduces the means of the value of engineering for the selection and further optimization in program design. This paper establishes a new model of celerity estimation on architectural engineering based on applying the grey system mathematics and calculation method. The model will be applied to actual projects , it has the characteristics of fast and simple. the estimated project cost is not more than 5% , Investment estimates of cost control has higher credibility and larger Practicality,This model eliminates a great many complicated and overloaded engineering calculation. In the last, it explores the ways of the cost control in the phase of design.Against the present condition that people neglects the management of the engineering cost in the investment deciding stage and project designing stage, the thesis analyses and studies the methods and application of the cost control in the earlier stage from two stages,it provides enterprise with the scientific gist on the celerity investment decision-making. |
