A Study Of The Control Of The Project Cost During Building Structure Design Phase

Any a project is feasible, and the engineering cost is to determine how much the projectfeasibility of important factor. So the project cost control, should be throughout the wholeprocess of project construction. Including investment decision stage, the design phase, projectconstruction contract is awarding stage and the implementation stage. The analysis shows thatthe design phase shall generally equivalent to the life of the construction project cost under1%, but to the cost of the influence is as high as75%above. A good structure design can notonly to satisfy the use function of building demand, the most is to reduce cost, bring hugeeconomic benefits. Therefore is how to optimize the design scheme for the engineering thefirst topic of discussion and study. Therefore, we should improve the design personnelstructure optimization design for the attention of, through technical, economic analysis andcomparison effect evaluation, the construction cost is minimized, create as far as possible bigsocial benefits, and gradually improve the design concept of their own design personnel.This paper introduces the current domestic and international construction design stageproject construction cost control research present situation and the existing problems，Thenaccording to the building structure design and engineering cost of the relationship,respectively, from Macroscopic and microcosmic two respects on the main influencing factorsof construction cost are analyzed，Followed by the further study of architectural engineeringdesign process of engineering cost control theory and method, combining with twoengineering examples，Guangdong Qingyuan residential6Layer residential structure andGuangdong Wuchuan district28building structure design optimization， to discuss how todo cost control and structural design optimization in actual work. Again on the buildingstructure design stage project construction cost control should be perfected in the process ofinvestment control of mechanism and management system were proposed, finally the futurestructure of cost controlling of design development direction are discussed, We should putforward to meet the long-term benefit structure (structure using the length of time or in caseof disaster loss expectation) case, minimizing the structure of the investment in the near future(cost) and to improve the structural reliability and rationality. Through structural designoptimization technology, the designers from the passive analysis, checking into active design,is the overall scheme design of rational decision-making, achieve the design goal--Application, security and economy.
