Singular Responsibility: With both design and construction in the hands of a single entity utilizing a turn-key single source responsibility there is a single point of responsibility for quality, cost, and schedule adherence.  The design-builder is motivated to deliver a successful project by fulfilling multiple parallel objectives, including aesthetic and functional quality, budget, and schedule for timely completion.

Quality: The singularized responsibility inherent in design-build serves as a motivation for quality and proper project performance.  During the construction process this attention to quality does not end, as the designer becomes the master builder, and manages the construction of the project to completion.

Cost Savings: Design and construction personnel, working and communicating as a team, evaluate alternative materials and methods efficiently and accurately.  Value engineering and constructability are utilized continuously and more effectively when the designers and contractors work as a team during the entire design process. Architectural design costs are usually reduced significantly and the cost of the Architect to review the construction is eliminated.

Time Savings: Because design and construction are overlapped and because bidding periods and redesign are minimized, total design and construction time can be significantly reduced.  With design-build, many decisions on details can be made as the project moves on.  The resulting time savings translates into lower costs and earlier utilization of the completed project.

Early Knowledge of Construction Costs: Construction costs are known far earlier than in other delivery systems.  The entity responsible for design is simultaneously estimating construction costs and can accurately conceptualize the completed project.
