CCP Schedule Coordination & OPR 2 — Questions and Answers
Question 1: During commissioning schedule development, who is primarily responsible for integrating the commissioning milestones into the overall construction schedule?
- The building owner
- The commissioning authority (CxA) (Correct answer)
- The general contractor
- The design engineer
Correct answer: The commissioning authority (CxA)
The commissioning authority is responsible for developing and integrating commissioning milestones into the master project schedule.
Question 2: Which Owner's Project Requirements (OPR) element directly informs the commissioning schedule for HVAC systems?
- Occupancy and operational hours (Correct answer)
- Material specifications
- Bid package structure
- Permit timeline
Correct answer: Occupancy and operational hours
Occupancy and operational hours defined in the OPR dictate when HVAC systems must be functional, driving commissioning schedule targets.
Question 3: A commissioning schedule shows pre-functional testing scheduled before TAB. What is the correct assessment of this sequence?
- Incorrect — TAB must precede pre-functional testing
- Correct — pre-functional testing verifies equipment readiness before TAB begins (Correct answer)
- Incorrect — both activities should occur simultaneously
- Correct — TAB results are required to write pre-functional checklists
Correct answer: Correct — pre-functional testing verifies equipment readiness before TAB begins
Pre-functional testing confirms equipment is installed and operational before testing and balancing (TAB) begins.
Question 4: An OPR states that the building must achieve LEED certification. How does this requirement affect the commissioning schedule?
- It has no effect on schedule
- It adds fundamental commissioning activities and documentation milestones (Correct answer)
- It only affects the design phase schedule
- It shortens the schedule by eliminating redundant testing
Correct answer: It adds fundamental commissioning activities and documentation milestones
LEED fundamental commissioning requirements add specific activities, reviews, and documentation deadlines that must be incorporated into the schedule.
Question 5: Which scheduling tool is most effective for identifying commissioning activities that are on the critical path?
- Gantt chart only
- Critical Path Method (CPM) network diagram (Correct answer)
- Linear schedule
- Resource-loaded bar chart
Correct answer: Critical Path Method (CPM) network diagram
CPM network diagrams identify task dependencies and calculate which commissioning activities, if delayed, will delay project completion.
Question 6: The OPR requires the building automation system (BAS) to be fully functional 30 days before occupancy. What commissioning activity must be completed before this milestone?
- Certificate of occupancy issuance
- BAS point-to-point verification and integrated systems testing (Correct answer)
- Furniture installation
- Landscape completion
Correct answer: BAS point-to-point verification and integrated systems testing
Point-to-point verification and integrated systems testing of the BAS must be complete before declaring the system fully functional.
Question 7: When a commissioning schedule conflict arises between the mechanical contractor's work and commissioning testing windows, who resolves the conflict?
- The mechanical contractor alone
- The commissioning authority in coordination with the owner and general contractor (Correct answer)
- The design engineer unilaterally
- The local authority having jurisdiction
Correct answer: The commissioning authority in coordination with the owner and general contractor
The CxA facilitates resolution by coordinating with the owner's priorities (OPR) and the general contractor's construction schedule.
