In the design-build approach to project delivery, the owner contracts with a single entity – the designer/builder – for both design and construction of the facility. The design-build entity can be led by either an architect or a general contractor and can consist of any number of people. Owners interested in a single-point of responsibility for both design and construction can use the design-build delivery system. In the design/build project delivery method, a single point of contact has been proven to foster better communication, reduce adversarial roles between design and construction, and accelerate project delivery which makes it the most advantageous.
In design-build, a consolidated entity provides both design and construction services to the owner. A single contract is established between the owner and the architect – contractor or design-build entity. Design-build approaches require an explicit determination of the roles and responsibilities of the design-build team.
