Which statement best describes the typical organizational structure for commissioning on a building renovation?

• A. A fixed structure unrelated to project delivery method
• B. An organizational structure as shown in figures depending on plan-and-spec or design-build
• C. No defined structure; ad-hoc
• D. A single contractor handles all commissioning

Answer: (B)

The main idea is that who does the commissioning and how they fit into the project team changes with how the project is delivered. In a renovation, the commissioning organization is typically shaped by the chosen delivery method. If the project uses plan-and-spec, there’s usually a clearer separation between design and construction, so an independent commissioning authority coordinates with the design team and contractors to verify systems meet requirements. If it’s design-build, the design-builder often absorbs or integrates many commissioning tasks within their team, though the owner may still require independent oversight. Either way, the org chart for commissioning follows the delivery method to ensure clear responsibilities, authority, and communication.

That’s why describing the organizational structure as dependent on plan-and-spec or design-build best reflects real practice. Fixed structures, ad-hoc approaches, or a single contractor handling all commissioning don’t align with how the delivery method drives roles and responsibilities.
