Benchmarking, Benchaction, and Benchlearning: Rework Mitigation in Projects

Abstract

The Australian government has issued several calls to improve the performance of the construction industry. A lack of available benchmark metrics has made it difficult, if not impossible, for organizations to identify areas to target for process improvement. A significant factor that has been found to contribute to poor organizational and project performance is rework. Using the results of a questionnaire survey, the paper presents and discusses a series of benchmark metrics for the causes and costs of rework for 161 construction projects. A generic framework for benchmarking rework at the interfaces of a project’s life cycle is proposed, and unstructured interviews are used to subject the proposed framework to validation by industry practitioners.
