The Study Of Constraction General Contract Project On Valution Methods

General contractrefers to the contract model that entrusted by owners,the generalcontractor completes the whole process or certain stages of a project from the prospective design to the completion acceptanceand everything else.This model has the advantage of resource conservation and optimization of resources allocation,meets the needs of developing the modern architecture industry and represents the contract model ofinternational mainstream.However,in the construction area,there is no valuation method is suitable for engineering contracting mode.Therefore,the strongly promoting and developing of general contract model needs establishing the project valuation method that is suitable for the characteristic of general contract badly.Based on the expatriation of the concept and character of general contract model,this text combs its development status,the study of scholars abroad and inside and the present situation of relative pricing.Making the professional industry of general contacting model the target of research,such as electric engineering,highway engineering,hydroelectric engineering,the basic situation,the cost structure are a comprehensive collection and refining,and explore its advanced characteristics.And then combined with the construction of its own characteristics,to analyze the valuation of Construction Engineering project contracting under the mode of the construction general contracting mode is divided into the feasibility study stage,the design stage,the preliminary design stageare discussed,it adopts the method that combines theoretical analysis and mathematical analysis,and proposes the budget unit method that meets pricing general contract in the early stages and that prices the project in three different situations,after an overall analysis of engineering data and character.Meanwhile,according to the actual situation,the text proposes a creation of engineering cost database matching the initial design,and states from principles of database preparation,database classification method,database framework design,database entry,and database usage and maintenance and so on.The conclusion and prospect presented in this text,provide a new idea for the relative general contract project valuation method in our country’s constructional engineering,and also,a powerful reference for future researchers.
