With the traditional Design-Bid-Build (DBB) highway construction method, highway project may take up to 13 years to deliver. The Accelerated Project Delivery Methods (APDM) initiative is designed to help reduce the time it takes to deliver highway projects to the public. We are confident that with accelerated project delivery methods, State DOTs can deliver projects 50 percent faster. EDC is promoting APDMs such as Design-Build (DB) and Construction Manager/General Contractor (CM/GC), which have proven to shave years off project schedules in some cases
With DB project delivery, the designer-builder assumes responsibility for the majority of the design work and all construction activities. This provides the designer-builder with increased flexibility to be innovative, along with greater responsibility and risk.
CM/GC occupies the middle ground between the traditional (DBB) and (DB). In a typical CM/GC scenario, the owners of a project contract with a general contractor to serve as the construction manager, to provide the owner with constructibility, pricing, and scheduling information during the design process. As the design nears completion, if the owner and the construction manager are able to agree on a price for construction, they sign a construction contract and the construction manager then becomes the general contractor. CM/GC allows State DOTs to remain active in the design process while assigning risks to the parties most able to mitigate them.
