Benchmarking Project Level Engineering Productivity

Abstract The benchmarking of engineering productivity can assist in the identification of inefficiencies and thus can be critical to cost control. Recognizing the importance of engineering productivity measurement, the Construction Industry Institute (CII) developed the Engineering Productivity Metric System (EPMS) composed of a series of hierarchical metrics with standard definitions suitable for measuring engineering productivity at various levels. While the EPMS can be used to assess engineering productivity at multiple levels within a discipline, it cannot produce an overall project level productivity measurement due to the underlying method of defining productivity. Previous studies have attempted to develop other metrics to assess engineering productivity at the project level; however, these methods did not create metrics suitable for benchmarking. To overcome these limitations, this study developed a standardization approach using “z-scores” to aggregate engineering productivity measurement from ac...
