THE ALTERNATE TECHNICAL CONCEPT PROCESS FOR FOUNDATIONS AT THE NEW MISSISSIPPI RIVER BRIDGE, ST. LOUIS

The New Mississippi River Bridge (MRB) employed conventional designbid-build procurement, but the bidding process included the opportunity for pre-qualified bidders to develop and propose confidential Alternative Technical Concepts (ATC’s) for evaluation and approval in advance of bidding. The ATC process provides a mechanism for value-engineering prior to bid, with incentives and opportunities for both the owner and the bidding contractor.
