Application Research Of Value Engineering In The Design Stage Of Construction Project

The design of construction project is the only way to turn decision and imagine into reality, meanwhile, it is also the economical and technical document which guides the implement of itself. The design stage basically decides the scale, standard and function of construction project, it also forms the design budget and determines the maximum amount of investment. The impact of this period to total investment of construction project is more than 75%, so under the premise of guaranteeing functions, the use of VE principles and methods in this period will optimize the function structure and reduce the costs, it is the key stage of improving the project value.This article firstly analyses the research status of VE in the design stage of construction project, it establishes the research ideas and framework, summarizes the theory and applications of VE. Secondly, it discusses the division and functional analysis of construction project in the design stage, and builds a project optimization design model with using VE principles, which including the selection of function object, the decision of design cost coefficient, the design of evaluation model, the usage of calculated result for value coefficient, the making method of improving plans. Finally, for the constructed project optimization design model, combined with the project practice of sports engineering, the application of VE in the design stage of this project will help the selection and optimization of plans. Through the application of VE principles in design stage of sports engineering, the function value of engineering is increased while the cost is reduced, so that the project operates two months earlier and saves about 2.6 million yuan for the construction cost and maintenance fee, and gains a very good economic and social benefits.
