CCP Cx Plan & Issues Log 3 — Questions and Answers
Question 1: What is the primary purpose of including a communications plan within the Cx Plan?
- To satisfy building permit requirements
- To establish how commissioning information is distributed among project stakeholders (Correct answer)
- To document the contractor's scheduling software
- To outline the design engineer's quality control process
Correct answer: To establish how commissioning information is distributed among project stakeholders
A communications plan within the Cx Plan defines meeting schedules, reporting formats, and distribution lists so all stakeholders receive timely commissioning information.
Question 2: An Issues Log item is marked 'Deferred' — what is the most appropriate next action?
- Delete it from the log since it won't be addressed
- Assign a target date and carry it into the post-occupancy or warranty phase (Correct answer)
- Escalate it immediately to the building official
- Re-classify it as 'Closed' to keep metrics clean
Correct answer: Assign a target date and carry it into the post-occupancy or warranty phase
Deferred items must retain their log entry, be assigned a future target date, and be tracked through warranty or post-occupancy commissioning to ensure resolution.
Question 3: Which Cx Plan component establishes the sequence for testing interdependent systems such as fire/smoke and HVAC?
- Issues Log
- Commissioning Schedule and Phasing Plan (Correct answer)
- Submittal Review Log
- Training Plan
Correct answer: Commissioning Schedule and Phasing Plan
The Commissioning Schedule and Phasing Plan determines the order in which systems are tested, ensuring interdependent systems are commissioned in the correct sequence.
Question 4: During a commissioning meeting, a contractor disputes an Issues Log entry claiming the work meets contract documents. What should the CxA do first?
- Delete the issue to avoid conflict
- Reference the OPR and Basis of Design to determine if the contract documents themselves conflict with design intent (Correct answer)
- Escalate immediately to the owner for a change order
- Accept the contractor's position and close the issue
Correct answer: Reference the OPR and Basis of Design to determine if the contract documents themselves conflict with design intent
The CxA should first check whether the contract documents align with the OPR and Basis of Design before escalating or closing, since the issue may reflect a design gap.
Question 5: How does the Cx Plan address equipment that arrives on-site with factory-installed controls that cannot be field-verified?
- Such equipment is excluded from commissioning by default
- The plan should specify factory witness testing or third-party certification as the verification method (Correct answer)
- The CxA signs off based on the submittal approval alone
- Manufacturer's verbal confirmation is sufficient
Correct answer: The plan should specify factory witness testing or third-party certification as the verification method
When field verification is not possible, the Cx Plan should require factory witness testing or an accepted third-party certification to confirm controls performance.
Question 6: Which metric is most useful for evaluating the efficiency of the commissioning process using Issues Log data?
- Total number of submittals reviewed
- Average time from issue identification to closure by responsible party (Correct answer)
- Number of commissioning team meetings held
- Total square footage of the project
Correct answer: Average time from issue identification to closure by responsible party
Average issue resolution time tracks how quickly deficiencies are corrected, providing a direct measure of commissioning process efficiency and contractor responsiveness.
Question 7: The Cx Plan should reference which ASHRAE guideline as the foundational standard for commissioning process requirements?
- ASHRAE 55
- ASHRAE Guideline 0 (Correct answer)
- ASHRAE 62.1
- ASHRAE 90.1
Correct answer: ASHRAE Guideline 0
ASHRAE Guideline 0, The Commissioning Process, provides the overarching framework and requirements that define a complete and credible commissioning process.
