Cost Factors High-speed Rail Station House Design Phase And Correlation Study

With the development of China’s high-speed railway project cost control has become the focus of attention. In the high-speed rail station house construction, the design stage of investment housing projects throughout the high-speed rail station plays a decisive role. So the impact on high-speed rail station building design phase cost factors and correlation of it is necessary, has important practical significance.Aiming at current situation of high-speed rail station house construction project cost management in the design phase and problems, combined with the Chengdu station expansion and reconstruction of the project to discuss, analyze issues related to the design phase of the impact cost. Analyze the different design of high-speed rail station house cost by analogy, part of the cost structure by establishing a data model for high-speed rail station house design division of influencing factors were analyzed. It was found that, from a management point of view, high-speed rail station house design stage cost factors according to the degree of influence as follows: the survey and design phase of the achievement and quality; the results of the early stages of work and quality; to survey and design of the control and management; budgetary estimate editorial quality. Quantification analysis, and the hub of Chengdu, Chengdu station as a case on the weight of each factor and correlation analysis from a management point of view the use of the Analytic Hierarchy Process(AHP), obtained the results of the survey and design phase and quality weight 56.7%. Others were: the early stage of work product and quality weight 27.3%; control of management rights for the survey and design of weight of 10.4%; general budget pipeline quality weight 5.6%. From a technical point of view, the design is mainly a greater impact on the project cost, case studies found that high-speed rail station house design Alternatives can use comparative analysis, value engineering method, which can evaluate alternatives for the proposed discussion, optimum embodiment in order to achieve the lowest cost to achieve the necessary functions. Based on the above analysis, in order to further improve the design stage of the project cost control, the owners of the proposed project construction unit HACCP quality preliminary work and the quality of work and results of the design phase, to strengthen the survey and design of the control and management, design and supervision of the proposed optimization reward programs; design and optimization unit emphasizes preferred design; pipeline unit increase budget estimate budget estimate editorial standards and quality. So as to achieve the purpose of improving project value, really the whole process of the project, especially in advance of the effective control.
