Design-Build is a construction delivery method that provides owners with a single point of contact for both the design and construction phases of a project. One entity holds single-source responsibility and contractual risk for every aspect of a build — from estimation, assessments and pre-construction to architecture, schematics, engineering, subcontracting, construction and post-construction. This entity, the Design-Builder, manages all contracts with companies, such as subcontractors, equipment vendors and materials providers.
