Which document is the AIA design-build contract between Owner and Design Builder?

• A. A141, Agreement Between Owner and Design Builder
• B. A101, Agreement Between Owner and Contractor
• C. C201, General Conditions
• D. E201, Data Exchange

Answer: (A)

In design-build, the owner signs a single contract with the design-builder who provides both design and construction services. The document that formalizes this relationship is the Design-Build Agreement between the Owner and the Design-Builder. It sets the scope, responsibilities, compensation, and risk under one integrated agreement, reflecting the single accountability and collaborative flow of a design-build project. The Owner-Contractor agreement is used for traditional design-bid-build where design and construction are separate; the General Conditions establish the baseline terms for the project and can accompany various contracts; and the Data Exchange document governs information-sharing processes rather than establishing the contract itself.
