To optimize the design of argumentation, the purpose of which is to adopt the design scheme is it technically feasible, function can satisfy the need, economically whether reasonable, whether using on safety and reliability. Especially in economy, design optimization is important means of control, a new process of use, new material of dedication, some local design change etc, these factors change, often make engineering cost greatly increase or decrease. According to research data shows, the department of construction project is sensitive, space layout, layer number and layer are tall, structure and the choice of materials, design of the selection of the factors, the direct impact on the discretion of the engineering cost. So, want to control the engineering cost in the design phase, she will do it well design optimization of work, in the design stage design bidding and the design scheme of the campaign, and use of value engineering means of alternatives to optimize design scheme, which will be the technical and economic evaluation, achieve true with optimal design, the most economic investment, to build the best project purposes.Construction engineering cost control process, is project cost management is the main form, is to improve the project investment benefit is the key, it is perforative in decision evaluation phase, design phase, project contracting stage, construction implementation stage, such as the pletion acceptance stage project construction process. Scientific subtle and systematically stages setup investment control target, can pass aim control, in the project investment decisionmaking, design, and implementation stage, the outcontracting investment amount control before the approved limits and to rectify within ed., ensure investment target smooth realization and make investment estimation, project budget, contracting estimates, the design contract price more reasonable accurate, real and reflect the objective project reality, effectively preventing the budget process amount exceeds the estimation, the budget exceeds the budget estimates, the pletion of this settlement SanChao phenomenal happening, to the greatest extent reasonably using human, material and financial resources, thus achieve better investment benefit and social benefit.6 / 6。t even break the control.Engineering design and project cost is supposed to be a unified whole of mutual coordination and cooperation to promote the two tasks, and in our practice, but like a different path Benz two car, village populated, without relevance. Design department。s macroeconomic control by market mainly formed engineering cost price mechanism, was also must in unity quantity calculation rules and social average real consumption quota, follow the modity economy based on the law of value, establishment of market mainly formed cost price mechanism: one is to fully realize price volume separation. The gover
