The Construction Project Cost Control Research

With the continuously progress of market economy system reform and the advance of the biding system, the system of enterprise production management and administration with the center of engineering project management have been formed. The construction engineering projects have been assigned by local government formerly also be put on the market nowadays, it is an opportunity but also a challenge to those construction enterprises. The earnings upside is probably very limited thanks to the enterprise undertaken engineering project by the comparison of bids. So, it is a great load to the construction enterprises to obtain economic benefits while the bid price is relatively low.The thesis firstly introduces briefly the concept of the project and the project management, then analyzes system of the project cost control and the tools and techniques of risk identification, which including the ABC classification method, AHP analysis method and Earned Value management method. Finally illustrates application of above-mentioned three methods in the process of the construction management through an actual enterprise case. The construction project cost involves many elements, include labor costs , machinery costs and material cost, etc., so firstly ABC classification method is adopted to analysis main elements of the construction cost and distinguish priorities and general objects. Then the essential elements can be determined to control discriminatively. Secondly, there are many cost risk would be taken place in the process of construction, such as economical risk, natural risk and technical risk which can be foreseen or even can't foreseen. Some risk may be result in great influence on project cost, so AHP analytical method is used to compare various cost risk factors and reduce those decisive risks effectively. The last, in view of the phenomenon that the time limit and cost don't be thought much of until the project to pack up. The Earned Value analysis can be adopted to make control on the event regularly, realize currently the condition of project operation and find out the cause of overspends and take correct actions in time.
