Study On Influence Factors And Control Measures Of Extra-high Building Construction Cost

In the recent twenty years, along with our country economic potentialityenhancement, extra-high building’s development obtains an unprecedented greatachievement, building scale and height also make constantly breakthroughs. Facing thefurious competition in construction enterprise market at the present times, the problemabout how to reduce the construction cost of extra-high building seems particularlyoutstanding. However, the construction of extra-high building has plenty ofcharacteristics, such as big quantities, excessive working procedures, cooperate withcomplex, great height, the amount of high place work and vertical traffic and so on, so itis complex to construction technology and organization management. And, the artificialand mechanical drop effect of construction process is obvious, but due to less dropeffect clause of existing quota, it will go against controlling the construction cost ofextra-high building. Therefore, it has become an indispensable issue of constructionenterprise managers and also is a sign of contracture technology level about how tooptimize the construction organization scheme of extra-high building and reduce theconstruction cost.At first, the paper analyses the current development situation of extra-high buildingand consist of construction cost, and concluded the key factors influencing artificial cost,mechanical cost and measures cost. Then, combining with plenty of investigation dataof extra-high building case in Qingdao, the paper makes a quantitative analysis aboutincreasing cost during extra-high building construction, and obtains more detailed andcomprehensive artificial and mechanical drop effect coefficient than existing quota. Inthe end, according to each key factor of influencing extra-high building constructioncost, the paper puts forward control measures of complying with construction cost ofengineering practice, especially the choice of mechanical in the construction processand establishment of measurement items are discussed in detail, which providestheoretical security to control the construction process cost of the extra-high buildingfor the construction enterprise.Through the study of the subject, it can benefit not only controlling constructioncost and improving benefits, but also promoting the international competitiveness ofChina’s construction enterprise in extra-high building construction field. As a result,construction enterprise can play a part in the fierce international competition and promote the development of construction technology continually.
