Which delivery method provides a single source of responsibility and typically a single contract for both design and construction?

• A. Design-Build
• B. Fast Track
• C. Cost-Plus with GMP
• D. CMc

Answer: (A)

This delivery method centers on one contract with a single entity that has responsibility for both design and construction. The owner contracts with the design-builder, who handles the design work and then manages or performs the construction, coordinating all design and build activities as a unified team. This creates a single point of accountability, so liability and communication are streamlined: issues are owned by one party, not split between architect and contractor. The integrated approach also encourages early collaboration, as constructability and cost consequences can be considered during design, often yielding faster delivery and fewer change orders.

Other methods typically involve separate contracts or channels of responsibility, which can lead to more coordination challenges and finger-pointing when issues arise.
