What is the difference between traditional project delivery and CM/GC?
The traditional Design-Bid-Build (DBB) delivery method involves a linear sequence of the design, advertisement, bid, and construction phases. All of the risk in DBB delivery method resides with the owner. The CM/GC delivery method allows the owner, construction manager, and designer to work together, identify the risks, and negotiate their allocation. The owner benefits from the constructability, pricing, and innovation feedback from the contractor that is incorporated into the final design package. Utah DOT experienced a change order average rate of 2.6percent on CM/GC projects in comparison with a 12percent rate on traditional DBB delivery projects.
