Identify a typical team member of the Cx Team.

• A. Commissioning Authority
• B. Mechanical Contractor
• C. End user
• D. TAB agency

Answer: (A)

The person who leads and coordinates the entire commissioning process is the Commissioning Authority. This role is typically the primary point of contact responsible for defining the Cx scope, developing the Cx Plan, and guiding all verification activities. The CxA oversees the sequence of testing, observes functional performances, tracks issues, and ensures documentation demonstrates that systems meet the owner’s requirements and the project’s design intent. While others such as the mechanical contractor, TAB agency, or end users participate in the process, they rely on the CxA to provide leadership, maintain independence, and ensure the commissioning effort is integrated and objective.
