CBCP Commissioning Process & Documentation 2 — Questions and Answers
Question 1: What is the main purpose of a commissioning Issues Log?
- To track contractor payment milestones and change orders throughout the project
- To record deficiencies, non-conformances, and corrective actions identified during commissioning activities (Correct answer)
- To document owner-requested scope changes after the design phase
- To list all approved equipment substitutions submitted during construction
Correct answer: To record deficiencies, non-conformances, and corrective actions identified during commissioning activities
The Issues Log is a living document that tracks every deficiency found during commissioning, the party responsible for correction, and the resolution status to ensure nothing is overlooked.
Question 2: A Systems Manual differs from an Operations & Maintenance (O&M) manual primarily because it:
- Contains only manufacturer cut sheets and equipment warranties
- Is intended for use only during the construction phase
- Integrates system-level operating information, sequences of operations, and commissioning data into a single resource for facility staff (Correct answer)
- Replaces the need for operator training during building turnover
Correct answer: Integrates system-level operating information, sequences of operations, and commissioning data into a single resource for facility staff
The Systems Manual goes beyond individual equipment O&M manuals to provide integrated, system-level guidance including design intent, sequences of operations, and how systems interact—making it a practical resource for operators.
Question 3: What is a 'deferred commissioning test' in the context of the commissioning process?
- A test that was failed during construction and must be repeated after repairs
- A functional test that cannot be completed during normal construction due to seasonal conditions or operational constraints and is scheduled for a later date (Correct answer)
- A test performed by the owner's staff rather than the commissioning authority
- A test that was waived by the owner due to budget constraints
Correct answer: A functional test that cannot be completed during normal construction due to seasonal conditions or operational constraints and is scheduled for a later date
Deferred tests are formally documented and scheduled for completion after initial turnover when conditions (such as extreme weather for heating/cooling systems) allow proper verification.
Question 4: Which of the following items should be included in a commissioning specification section within contract documents?
- The owner's financing terms and contractor payment schedule
- General contractor overhead and profit rates
- Contractor responsibilities for startup, documentation, and participation in commissioning activities (Correct answer)
- Architect's design intent narrative for aesthetic decisions
Correct answer: Contractor responsibilities for startup, documentation, and participation in commissioning activities
The commissioning specification defines what contractors must do to support the commissioning process, including startup documentation, attendance at meetings, and cooperation with the CxA during functional testing.
Question 5: What is the recommended approach when a functional performance test reveals a deficiency during commissioning?
- Issue a final certificate of completion and note the deficiency for future retro-commissioning
- Immediately halt all commissioning activities until the deficiency is resolved
- Document the issue in the Issues Log, assign responsibility, and re-test after the responsible party makes corrections (Correct answer)
- Accept the system as-is if the deficiency is minor and does not affect energy performance
Correct answer: Document the issue in the Issues Log, assign responsibility, and re-test after the responsible party makes corrections
Proper commissioning protocol requires all deficiencies to be logged, corrected by the responsible party, and re-tested to verify resolution before the system can be accepted.
Question 6: Operator and maintenance staff training documentation in the commissioning record should include which of the following?
- Only the dates when training sessions were held
- Training agendas, sign-in sheets, topics covered, and confirmation that staff received systems manuals (Correct answer)
- Contractor employee certifications and trade licenses
- Owner's insurance policy for equipment damage during training
Correct answer: Training agendas, sign-in sheets, topics covered, and confirmation that staff received systems manuals
Comprehensive training documentation verifies that facility staff received adequate instruction and resources to operate and maintain building systems per design intent after turnover.
Question 7: In the commissioning process, the term 'acceptance' of a system by the owner signifies that:
- All punch list items from the architect have been closed
- The system has passed all required functional performance tests and meets the OPR as documented by the CxA (Correct answer)
- The contractor's warranty period has officially begun based on permit issuance date
- The owner has received all equipment invoices and approved final payment
Correct answer: The system has passed all required functional performance tests and meets the OPR as documented by the CxA
System acceptance in commissioning is a formal milestone confirming the system performs per the OPR, backed by documented test results, and the CxA's professional recommendation to the owner.
