Which delivery method establishes design before procurement and construction?

• A. Design-Bid-Build
• B. Design-Build
• C. CMAR
• D. IPD

Answer: (A)

Design-Bid-Build uses a strictly sequential process: the design is completed before any procurement or construction begins. The owner hires a designer to produce a full set of design documents, then the project is bid to contractors, a contractor is selected based on the bids, and construction starts only after the contract is awarded. This creates a clear handoff from design to construction, with procurement happening after the design is finished. Design-Build combines design and construction under one contract, so design and construction phases overlap and progress together rather than one finishing before the other. CMAR involves early contractor involvement during design and typically proceeds to construction after design decisions are made and a price is set, with ongoing collaboration rather than a strict handoff. IPD brings the core team together from the start with integrated delivery; design, procurement, and construction activities are all performed collaboratively from day one.
