Unlike traditional Project Delivery, where the owner must handle separate projects, U.S. 89 Farmington to I-84 was the first Progressive Design-Build Project in Utah built by Oak Hills Constructors. Oak Hills Constructors is a joint venture between Sterling Construction’s subsidiary, Ralph L. Wadsworth and Granite Construction. In Progressive Design-Build Projects, the owner manages only one contract with a single point of responsibility. The designer and contractor work together from the beginning as a team, providing unified project recommendations to fit the owner’s schedule and budget. Any changes are addressed by the entire team, leading to collaborative problem-solving and innovation. While single-source contracting is the fundamental difference between design-build and traditional contracting methods, equally important is the culture of collaboration inherent in design-build. The $348 million, three-and-a-half-year project is expected to be completed in September, and the results are nothing short of amazing. Here is a recap of the project.
