With the gradual improvement of the socialist market economic system , the various construction enterprises in terms of cost , to strengthen the management, but the traditional cost management methods are increasingly exposed its drawbacks : ( 1 ) cost management scope is too narrow , the depth is too shallow ; ( 2 ) cost management methods behind ; ( 3 ) the cost of management information degree is not enough . Address these drawbacks , this paper analyzes and then put forward countermeasures perfect project cost management , forecasting, planning and optimization process , and its application in the project before construction , the construction cost of the project , for the strengthening of the construction project cost management of information technology to improve the the construction competitiveness of enterprises have a strong theoretical and practical significance . In response to these problems this paper to carry out the following work : first introduces the research background of the paper , an overview of the status of the project management , and cost management of construction enterprises Present Situation and Cause Analysis The purpose of this study and the main ideas. Project cost management principles , measures and cost management , job responsibilities, and discusses the content and management of cost management process . Secondly , for the composition of the object of the project cost analysis , mathematical statistics , historical data has been made to establish its time relationship model , with engineering examples describe in detail the cost forecasts are several ways . Prepared on the basis of the construction cost of the project plan , the monthly cost of the scheme and the target cost plan , principles , procedures and methods , and project cost control principles , based on methods and implementation steps and procedures were introduced . Three control the relationship between the target according to the construction project , the establishment of the project cost, schedule, and quality optimization model , combined with engineering examples of its use are described in detail . Finally , on the basis of the analysis and demonstration given should adhere to the basic principles of project cost management process and pointed out that the qualitative prediction based cost control .
