US Navy Contracted Construction Delivery Methods: Recent Project Performance Analysis, Review of Alternative Delivery Methods, and Recommendations for the Future
Abstract
Navy and Marine Corps shore infrastructure construction has been completed with either Design-Build (DB) or Design-Bid-Build (DBB) delivery methods since the late 1980s; meanwhile, alternative project delivery methods (e.g., Construction Manager at Risk and Integrated Project Delivery) have been developed to improve construction project performance. This research compared current Navy construction delivery methods, developed a schedule growth prediction formula for these methods, examined alternative delivery methods, and developed recommendations for updating Navy procurement methods. The research found that DB outperformed DBB in both cost control (29 reduction in cost growth) and project changes (76 reduction in changes per million dollars). There was no statistically significant schedule growth difference between DB and DBB. The schedule growth model predicts that the most complex projects will suffer the most schedule growth, followed by the lowest complexity projects, with the least schedule growth expected on projects of average complexity. The Integrated Project Delivery (IPD) method was recommended as a potentially superior alternative to DB. Because full implementation of IPD could require changes to federal procurement policy, a number of recommendations were made to incorporate elements of IPD to improve the Navy's current DB model.
