This paper discusses four public agency approaches to applying alternative technical concepts (ATCs) to construction manager–general contractor (CMGC) project delivery through an analysis of case study projects.
The CMGC projects included a slope stabilization project in Michigan, a
bridge in Oregon, the urgent, in situ foundation stabilization of a dam in
Kansas, and a commuter rail project in Utah. The study results showed
that ATCs provide a valuable mechanism to identify the best qualified
contractor during the CMGC selection process. ATCs also permit an
owner to consider innovative design solutions to constructability problems through the contractor’s early involvement. The addition of ATCs
to CMGC procurements permits an owner to accrue all of the savings
offered by a contractor’s ATCs because the contractor’s preconstruction
services’ contract compensates the contractor for developing the ATCs.
