investment decision is made, the key lies in designing. According to expert analysis: architectural design, in the preliminary design stage, design stage, construction design stage to the engineering effect were 75% ~ 95%, 35% ~ 75%, 5% ~ 35%。 while in the construction phase, through the optimization of construction organization design, construction cost saving the possibility of only 5% to 10%. We should put the focus shifted to the design stage, in order to get twice the result with half the effort.Pay attention to the technical and economic optimization bination. The bination of technology with economy is most effective way to control engineering cost. China engineering fields for a long time did not do this. The lack of technical personnel economy idea, design thought is conservative, the design of the oute of the economy are not fully reflect. Therefore, we should solve the problem is to improve economic efficiency as the goal, in the construction process, organization, technology and economy organic ground union rises. Through the economic analysis, parative study and effect evaluation, correct processing of advanced technology and reasonable in economy between the relation of unity of opposites, strive to advanced technology under the conditions of economic rational, reasonable in economy based on advanced technology.Carry out limitation is designed method. To be consciously put the application of value engineering to the specific design, actively promote quota design in engineering design contract, by way of bidding. This has been proven in practice is an effective way, it is not only an economic problem, more precisely a technical and economic problems. This limitation is designed to effectively control the project cost. In order to make the limitation is designed to achieve the desired objectives, should be involved in the design personnel must be experienced skilled economic designer. Their design results must be practical, advanced and reasonable cost. Control of engineering cost on the other hand is
