Correlation of Construction Performance Indicators and Project Success in a Portfolio of Building Projects

Construction management is a highly competitive project-based field of complex specialized services, creating or altering the built environment for a client. For construction projects to be successful, and in turn, for construction firms to be successful, understanding the relationship of performance statistics as indicators of project outcomes, such as cost, time, and profitability, is essential. There have been a number of efforts made to identify key performance indicators related to construction project success. However, due to lack of available data, many questions remain. There lies an opportunity to analyze project statistics as indicators of project success, similar to the way analytics have been used to predict success in sports. Construction firm project data for a portfolio of building projects were analyzed, and this study identifies correlated factors for completed building construction projects. A highlight of this correlation analysis identified profit differential as demonstrating a strong relationship with the number of requests for information and architects supplemental instructions on a project.
