Large Infrastructure Construction Stage Project Cost Control

This paper uses theoretical research and case study method of combining the basic theory of project cost management and project cost analysis and prediction analysis of the methods discussed which based on the proposed "earned value" principle that cost effective dynamic analysis and control methods, and establish two unfinished for different periods of the cumulative project cost prediction model: the implementation phase of the project mid-term, the establishment of GM (1,1) Grey forecasting model point after Several of the project cost close to predict; late in the project, the establishment of a simple possible forecast model to predict the cost of all work in progress. In this paper, the "Foothills Phase II international gardens B3 plots three groups based on project", for example, the use of "earned value" principle of the construction phase of its project cost analysis of the dynamic and the time to find out the actual value of the construction plans the deviation, including the schedule variance, cost variance, and quality deviations. In the deviation analysis, based on the use of GM (1,1) Grey forecasting model based on works of the mid-term unfinished project cost was predicted, based on the budget results from the schedule, cost, quality, put forward three specific control measures to end to achieve large-scale infrastructure construction stage of project cost control.
