Table ES.1 below, summarizes the overall results, indicating the better performing delivery for six metric categories. (BMM 2002-10, p ix)
• Owners - There seemed to be a performance advantage when the DB delivery system was used.
• Contractors – The performance advantage for one delivery system over the other was not as clear.
Practice use seemed to be a driver of performance results as much as project delivery system. No one project delivery system is likely to provide the best performance for all projects and for all participants.
