Which of the following is an example of documentation updated during the Design Phase Commissioning Process?

• A. Commissioning Process Progress Reports
• B. Quality Assurance Plan
• C. Updated OPR
• D. Final Construction Schedule

Answer: (C)

In the Design Phase Commissioning Process, the Owner’s Project Requirements (OPR) is treated as a living document that evolves as design decisions are made and owner expectations become clearer. As the project design progresses, the OPR is updated to reflect confirmed performance criteria, occupancy needs, energy targets, and other outcomes the project must deliver. This updated OPR then serves as the guiding reference for design decisions, system selections, and the commissioning verification plan, ensuring that the work being designed will meet the owner’s real requirements when the project is completed.

Commissioning Process Progress Reports are typically created to document ongoing commissioning activities and testing results, and are more aligned with the commissioning phase itself. The Quality Assurance Plan outlines QA processes and may be updated at various stages, but it isn’t specifically the documentation updated as part of refining design requirements during the Design Phase. The Final Construction Schedule is a construction-phase artifact that gets updated as construction progresses, not a design-phase commissioning document.
