Statistical Control of Time and Cost Performance Indices in Construction Projects: A Case Study

Abstract

The earned value management is a powerful and important technique in analyzing and controlling the project performance. While it allows exact measurement of project progress, it lets corrective actions in a timely manner. In fact, the earned value allows project managers to find out any project time and cost deviations by calculating the performance indices. In this paper, to improve the applicability of the traditional earned value technique, we develop an integrated approach by combining statistical quality control charts with traditional earned value technique, to monitor and control project time and cost performances. The results applied to a real construction project compete favorly against traditional approache
