largest effect on stage of design. In construction projects on the life period, preliminary design of the project of construction project basically decided the scale, structure, construction standards and use function, formed design budgetary estimate, determine the investment ceiling. After the pletion of the construction drawing design, formulate construction drawing budget, accurately calculate construction engineering cost. Therefore, engineering design is to influence and control of construction engineering cost of key sectors and an important stage. For a long time, we in the construction cost management, ignored in mon design phase project of investment control, and often take control project investment and project cost focuses on the implementation stage, put in a great deal of manpower and material resources to review or puting architecture installation project cost, seldom consider how to reach into reasonable fund, acquire beautiful generous, plete functions applicable, reasonable economy construction products. According to the domestic and foreign relevant statistics show that the preliminary design stage affected the project investment amount the amplitude of the possibility for 7090 percent, in the technical design stage (construction design) affect investment possibilities for 3075%, During the project construction phase (the implementation stage effect of project investment possibilities for 5% 25%. Or specifically, design phase affect the project investment possibility to 80%, and the possibility of the implementation stage affect investment, at best not exceed 20%, namely through various measures to reduce cost utmost nothing more than 20 per cent for the following. Normally design drawings once pleted, according to drawing construction is the principle of construction enterprise must perform, construction enterprises shall not be entitled to optional change drawings, also have no time, energy and take risks to consider optimization design. And our country there are generally design department conservative, some design only figure convenient, with experience without scheme contrast, even blind pursue safety and design fees, and budget control is vital interests with the design institute has nothing to do, so don39。s form, and fees immobilized, go against intuitivey reflect the project content price, and with the international quoted price way gap bigger also. In order to which investment macro decision and improve the benefit of investment project, must the plan formation of engineering cost price mechanism, instead of under the state39。 The current budget norm with legal nature and forced properties of budget ration direct fee fees standard, developers and contractors are altered arbitrarily, or planned pricing for the Lord。s macroeconomic control, taking market mainly formed cost price mechanism. The traditional budget norm system under the planned economy system, to strengthen the investment plan management, reduce waste aspects have certain positive role. But with the socialist market economy is grad
