| Abstract: | Design/build has become one of the favored project delivery methods in the engineering construction industry. Numerous studies have advocated the use of design/build over the traditional design/bid/build delivery approach. A comprehensive analysis of 67 global projects from the Construction Industry Institute's database shows that design/build projects may not provide all the benefits to project performance. The study found timesaving was a definitive advantage of design/build project delivery, but, the positive effects of cost and productivity changes were not convincing. Based on the results of the study, the project management expertise and experience of the contractor may have a greater impact on project performance outcomes than focusing on project delivery strategy only. |
