In a Design Build project, the commissioning organizational structure is identified as which entity?

• A. The Architect
• B. The Owner
• C. The Contractor
• D. The CxA

Answer: (B)

In design-build, the owner controls the commissioning process. The owner defines performance requirements, acceptance criteria, and test plans, and then appoints the commissioning authority (CxA) to manage and verify that the systems meet those requirements. The CxA may be internal to the design-builder or a separate consultant, but the commissioning structure—the governance and oversight of commissioning—comes from the owner. The architect focuses on design, the contractor on construction, while the CxA executes the commissioning activities under the owner’s direction.
