Research To The Influential Factors Of Construction Cost

For any proposed construction projects, in addition to considering the technical feasibility of the construction and the relevant national development needs, the most important is that the construction cost of the project is economic rationality. In order to effectively control the project cost so that the limited construction funds to play the greatest economic benefits, it is necessary to analyze the impact factors of the project cost. The influence factors of project cost are very much, from the point of view of construction cost, that is, the total investment of project project, this paper studies the influence factors of project cost.This article through to the domestic and foreign related cost influence factor research and the related document collection reorganization, and unifies our country engineering cost composition and the characteristic, to the project cost entire process management thorough understanding. According to the construction cost of our country, the construction unit management, design factors, construction management, social factors and other four aspects are the main causes of the project cost. In depth study of the four aspects of the project cost of the impact of the way and the extent of the impact, through the relevant literature and the actual situation of the project summed up the 12 factors that affect the cost of the project. In order to better analyze the relationship between project cost factors, this paper applies the Dematel model to analyze the relationship between the factors affecting the cost and the influencing factors. To determine the factors and reasons of cost factors in the factors, factors for pre planning, construction procedures, complete the design standard of quota design, design quality, policy adjustment and market price fluctuations and other factors such as force majeure; the factors for the increase of the content of the work, management factors, design of detail drawings settlement processing, construction organization design, construction progress, construction quality. Finally, combined with the engineering case influencing factors on the project cost of the project cost influence and influence degree are analyzed, determine the factors as the main factors influencing the construction cost, should focus on the control in the management of actual project cost.Finally, combined with the engineering examples and work experience on the project cost control of the factors to put forward opinions and suggestions. In order to facilitate the work in advance of some unfavorable factors in engineering management and take preventive measures, and can improve the efficiency of project cost management project cost management to achieve good results, and promote the healthy development of the oroiect cost.
