Arecent study by Dodge Data & Analytics provides insights into the impact that delivery systems have on projects from the perspectives of owners, architects and contractors. The research, published in the "Project Delivery Systems SmartMarket Report," primarily focused on three delivery systems: design-bid-build, design-build and construction management at-risk (CM at-risk). The findings reveal that there is no single, well-established delivery system most likely to improve project results across the board.
For example, most owners reported strong performance on budget and schedule for each system, with only minor differences well below the margin of statistical difference.
