Construction Item Cost Control Research

Project cost control is the important content in the project management and it relates to the contractors' economic efficiency and prestige directly. Therefore, the theory of cost_control study are very important to increase the Innovation capability and profit levels of enterprises.At present, there are a lot of theories and works in China's construction enterprises on the project management cost control, but still much defects, mainly reflected in the implementation of pre-planning, project control, hindsight summing , which not only give an impact on project cost control, but also cause direct distortion of the project cost.Firstly, this paper introduces the development and the status of project cost control. Secondly, it illustrates the system control theory, information theory and control theory principle of project cost control, the principle of the project cost control and the ways of cost control. Thirdly, with the comparison and analysis to the common project cost control method and basing on the combination of the actual work, it offers the phases of real-time cost control methods, and real-time cost control concepts, principles, processes and implementation procedures. Finally combination of a specific thesis project cost control in the case of real-time method of empirical analysis, real-time stages proved the effectiveness of cost control methodsit proves that the phases of real-time cost control methods are an important means of cost control through a successful real-time cost control case.
