Abstract
In 2018, CII and the Charles Pankow Foundation co-funded a research team that examined project delivery performance by comparing the cost, schedule, and quality performance of design-bid-build (DBB), construction manager at risk (CMR), and design-build (DB) projects. This project updated a CII study published in the mid-1990s that showed that DB project outperformed both CMR and DBB projects in terms of unit cost, cost and schedule growth, and all metrics relating to the speed of delivery.  CPF-RGA 02-18 examined data from over 200 projects of varying size, sector, complexity, and location. Then the team compared its results with the original CII study, which included data from over 350 projects. The results of the comparison show that the delivery speed for DB projects has increased over the past 20 years, while still providing a lower cost per square foot and greater reliability in cost and schedule performance.
