CxA stands for which role in commissioning projects?

• A. Commissioning Authority
• B. Construction x Agent
• C. Commissioning Agent
• D. Certification and Audit

Answer: (C)

CxA identifies the person who leads the commissioning process on a project, coordinating design reviews, test planning, system validation, and documentation to ensure performance aligns with the owner's project requirements. In this exam context, that role is specified as Commissioning Agent, the individual representing the owner's interests and overseeing the commissioning activities from planning through turnover. Some organizations refer to this role as Commissioning Authority, which is similar in function, but the terminology used here is Commissioning Agent. The option Construction x Agent isn’t a recognized role in commissioning, and Certification and Audit refers to verification activities rather than leading the commissioning effort.
