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 the old ways, equally important is the culture of collaboration inherent in design-build. This leads to faster project delivery, with more reliable performance and less cost and schedule growth.
