Which phase would verify the systems manual?

• A. Planning Phase
• B. Design Phase
• C. Occupancy and Operations Phase
• D. Construction Phase

Answer: (D)

Verifying the Systems Manual happens during the Construction Phase, when the building systems are actually installed and tested. The Systems Manual documents the actual equipment, controls, sequences of operation, maintenance requirements, and warranty information that will govern how the building runs. In this phase, the commissioning authority checks that the manual reflects what was installed and that the field changes are captured, ensuring the manual is complete and accurate before turnover. This makes sure the owner receives a ready-to-use guide for operation and maintenance. While the manual is used during occupancy, its verification and finalization are most effectively completed during construction and commissioning, so issues can be resolved before the building is occupied. Planning and Design set up requirements, and Occupancy relies on the completed manual, but the factual verification of installed systems belongs to the construction verification window.
