Study On The Suspension Bridge Construction Cost Of Influence Factors And Correlation

In suspension bridge construction, cost control is the key, but on the whole stage of design of suspension bridge project investment plays a decisive role. So the suspension bridge cost influence factors and their correlation is very important.Suspension bridge in China aiming at the design stage of construction project cost management present situation and the existence question, an in depth analysis of the design stage effect of suspension bridge construction project cost on the basis of factors, combined with Yunnan Longjiang bridge project were discussed, analyzed the influence factors of cost in design stage. Tightly around the suspension bridge cost influence factors and correlation of main research method is survey, expert consultation, through the collection of information, after finishing using analogy, according to bridge structure analysis. By analogy for the different design of suspension bridge cost analysis; through the establishment of data model of the suspension bridge branch design structure part cost factor statistical analysis. Came to the conclusion that the suspension bridge design phase cost the main influence factors for:prophase work quality and the work results; survey and design quality of the work and the results of survey and design quality; monitoring; budget document editing; design scheme selection, in the analysis of impact factors, using Yunnan as a case from the Longjiang suspension bridge management angle by using analytic hierarchy process (AHP) on the influence factors of weight and correlation analysis, the survey and design work quality and outcomes of quality is the most important affecting factor, followed by:prophase work quality and work of survey and design; monitoring; budget document editing. From a technical point of view is the main design to project cost influence, therefore, separate analysis. Finally, according to various factors make the reasonable determination and effective control of engineering cost in the design stage of the way and the method, to further improve the design stage project construction cost control and put forward some beneficial suggestions and control measures, so as to improve the value of the scheme, to effectively control the construction cost in the design stage and has a certain practical reference value.
