Using the Earned Value Management System to Improve Electrical Project Control

Abstract

In many cases, disorganized cost and schedule tracking practices, as well as inaccurate data collection, cause many projects to experience distress and possible profit loss. This paper introduces an earned value management system that allows electrical contractors to monitor construction progress, perform forecasts on the project, uncover problems occurring on-site, and respond to problems in the project as early as possible. This paper also presents a case study, along with its results, to supplement the application of the earned value management system. In the case study, several progress reports for the earned value system were used, including the field personnel loading curve, Hanna’s control points, S-curves, performance factor profiles, and work-hour forecasts. Results from the analysis showed that early determination of probable project outcome is possible with reasonable forecasting accuracy. Early warning signs are discussed and explained by the author. Using an earned value management system can also help detect cost overruns and schedule slippages early in the project, which makes it possible for the project team to take corrective measures in a timely manner.
