Which statement best describes the purpose of commissioning?

• A. To accelerate project completion at any cost.
• B. To minimize owner involvement.
• C. To ensure the finished facility operates in accordance with the owner's requirements and the construction documents.
• D. To replace the need for post-occupancy testing.

Answer: (C)

Commissioning is about confirming that a building's systems are designed, installed, tested, and calibrated to meet the owner's stated requirements and the project documents. This process provides documented evidence that operations, controls, and performance align with design intent, space needs, energy goals, and comfort criteria before occupancy and during use. It helps uncover and fix issues early, ensures proper training and documentation are provided, and reduces the risk of a facility underperforming. The other options miss the core aim: rushing to finish at any cost compromises performance; minimizing owner involvement undermines accountability for meeting requirements; and claiming post-occupancy testing is unnecessary ignores the ongoing validation of actual performance in real use.
