Value Engineering Design In Housing Construction Application Of Optimization

With the rapid development of reform and opening up, make a spurt of progress of national economy, large-scale projects in China are also developed, the engineering construction is a huge number, complex, long duration of action, the number of projects, large amount of investment in personnel, in order to better implement and management of engineering project so we must adopt scientific management system. In order to make the project cost saving projects. To reduce the cost of investment, profit maximization, and meet the function requirements in the project, we must using the method of the combination of technology and economy, the theory of value engineering. In view of the construction industry in our country in order to realize the optimization of project function and cost, is to strengthen the utilization and demand of value engineering, so that the value obtained further development.Currently existing value engineering in the creation of the program and evaluation of projects, selected object, the main information collection, evaluation and analysis of the function of the reach of project reporting, in order to enhance the value of projects, reduce investment costs, economic and social benefits of the project to obtain higher value engineering is the basis for the analysis-oriented, so that a plurality of related fields to collaborate to quickly find out the inputs and outputs of the project. Analysis of the project cost and functionality, continuous innovation, which is the main purpose of the application of value engineering to improve the value.Paper closely with engineering practice, after a brief description of the value engineering theory, the case closely, the use of value engineering theory and analysis of case studies. Then use the Analytic Hierarchy Process(AHP) to calculate the index weighting value of each function and determine the functional index weight; the first is the content of the real estate project design phase was analyzed with the aim of determining the value of engineering activities in functional evaluation using expert scoring method to calculate the coefficient function evaluation; combined with cost factors, to give the value of the coefficient of programs, and evaluated the design value, choose the optimal solution.Concluded, value engineering as a technical and economic method of combining just cater to reduce costs, improve performance target pursuit, played a big performance in the architectural design stage preferred, to optimize the design, thus improve its functional effect, reduce investment, so that the value of the project is improved.
