The largest single design-build highway contract in the United States provides for the reconstruction of 26 km of Interstate 15 (I-15) through the Salt Lake City metropolitan area in time for the 2002 Winter Olympics. The project includes the addition of new general purpose and high-occupancy-vehicle (HOV) lanes, the construction or reconstruction of more than 130 bridges, the reconstruction of seven urban interchanges, and the reconstruction of three major junctions with other interstate routes, including I-80 and I-215. In addition, the project provides for the construction of an extensive regionwide advanced traffic management system. Traditional contracting would have taken extraordinary coordination of multiple projects and an extended delivery period for completion, jeopardizing the ability of the Utah Department of Transportation (UDOT) to complete the project before the Olympic games and without prolonged traffic disruptions. The adoption of design-build as a contracting approach allows UDOT to meet scheduling demands and minimize disruptions to the public. It also allows UDOT to benefit from several private sector innovations and value-added features. |
