How project managers can better control the performance of design-build projects

摘要

The purpose of this study is to identify key factors that affect 11 areas of design-build (DB) project performance. Using data from 42 public and private DB projects, this study finds that contractor characteristics are the key determinants that affect the most number of performance metrics. The most important variable is the contractor's track record for completing projects on budget, on schedule and to acceptable level of quality. Other important determinants are contractors' capability and adequacy of their resources. It is recommended that project managers pay close attention to contractor selection in order to ensure that the different aspects of project performance are achieved.
