Tribute River Bridge In The Quality Of Life-cycle Cost Optimization

With engineering construction scale and construction investment growing, more and more projects begin to pay attention to conduct quality cost management work, especially in project construction phase, quality cost management of traditional quality management job is the perfect job, the traditional quality management exist many insufficiencies, if only to take the engineering quality and ignore the cost, but it is aimed at a certain stage of the project of quality management. Therefore, the bridge GongJiang project life cycle based on the construction, so as to achieve the quality cost optimization of project quality and improve the cost for the purpose of optimization, the objective quality cost management, provides the basis.GongJiang bridge life cycle quality cost optimizing management is divided into three stages: GongJiang bridge planning design stage, the stage of construction, operation maintenance and scrap dismantled stage. In the design stage by analyzing the influential factors of project quality cost, project feasibility study stage, use bridge panel of macro forecast analysis, the economic rationality, demonstration project introduced in the schematic design stage of value engineering, the scheme selection in the preliminary design and construction design stage through the application of reasonable basis theory, the forecast design scheme, which cost optimization engineering cost; In engineering construction stage through the perfect quality management system macro-control optimize the quality cost of engineering construction, then respectively might occur during the process of using the process capability to prevent cost optimization and mathematical model for the identification of cost by using significant test control of construction unit in the construction process of testing and measuring precision of cost is optimized, mainly through strict control optimize produced in project construction process of design change and design change the confirm optimizing internal unit cost, on the other hand by strengthening the construction stage of contract management, reduce the claim and the claim to optimize the external loss cost; Operation maintenance and dismantle scrap stage, distinguish different cost types and optimize management.
