I-440 Reconstruction From I-40 to I-24
What is Design Build? A project delivery method that • combines all or some portions of the design and construction phases of a project into a single contract. TDOT clearly defines the • standards, scope, and specifications for a project, and the Design-Builder works to satisfy those requirements. 20 October 2017 2
Why Design-Build? Shortened completion time by • overlapping design and construction Construction can begin before • all design details are final. Reduced claims due to design • errors/ omissions because construction happens under same contract. Shortened project delivery • time which can reduce user costs. Single contact point for • quality, cost and schedule from design through construction. 3
