In a plan and spec approach to HVAC commissioning, which statement best describes the independent hiring?

• A. Single contractor approach
• B. Independent hiring of CxA, designer, and contractor
• C. No owner involvement
• D. No documentation requirements

Answer: (B)

Independent hiring means the owner contracts the commissioning authority, the designer, and the contractor separately, rather than using a single entity to cover all roles. This separation preserves objectivity so the CxA can verify that HVAC systems meet the design intent and the owner's requirements without conflicts of interest. In this approach, the CxA develops the commissioning plan, conducts tests and observations, and documents results independently of construction and design decisions. This owner-controlled, multi-party setup is why independent hiring is the best description. The other options either undermine independence or omit owner involvement and documentation, which aren’t consistent with this approach.
