CCP Cx Process & ASHRAE Guideline 0 2 — Questions and Answers
Question 1: According to ASHRAE Guideline 0, who is responsible for developing the Owner's Project Requirements (OPR)?
- The commissioning authority (CxA)
- The design engineer of record
- The owner with assistance from the CxA (Correct answer)
- The general contractor
Correct answer: The owner with assistance from the CxA
ASHRAE Guideline 0 assigns responsibility for developing the OPR to the owner, typically with facilitation and assistance from the commissioning authority.
Question 2: During which commissioning phase is the Systems Manual first compiled?
- Pre-design phase
- Design phase
- Construction phase (Correct answer)
- Occupancy and operations phase
Correct answer: Construction phase
The Systems Manual begins to be compiled during the construction phase as equipment is installed and tested, then finalized before occupancy.
Question 3: What is the primary purpose of the Basis of Design (BOD) document in the Cx process?
- To serve as the final construction contract
- To document the design intent and assumptions that fulfill the OPR (Correct answer)
- To outline the contractor's construction schedule
- To define the commissioning authority's fee structure
Correct answer: To document the design intent and assumptions that fulfill the OPR
The BOD documents the design engineer's reasoning, assumptions, and technical approach used to satisfy the Owner's Project Requirements.
Question 4: Which statement best describes the role of 'deferred commissioning' under ASHRAE Guideline 0?
- Commissioning activities postponed due to contractor scheduling conflicts
- Formal Cx tasks that cannot be completed before occupancy and are scheduled for a defined future date (Correct answer)
- Testing that is waived because the system is under manufacturer warranty
- Commissioning of systems installed in a later project phase
Correct answer: Formal Cx tasks that cannot be completed before occupancy and are scheduled for a defined future date
Deferred commissioning refers to Cx activities that cannot be completed before occupancy but are formally documented and scheduled to occur at a specified future date.
Question 5: In the ASHRAE Guideline 0 Cx process, what document formally records deficiencies found during testing?
- Commissioning Plan
- Issues Log (Correct answer)
- Basis of Design
- Systems Manual
Correct answer: Issues Log
The Issues Log (also called a Deficiency Log) tracks all problems identified during commissioning, including their status and resolution.
Question 6: ASHRAE Guideline 0 identifies five commissioning phases. Which phase immediately precedes the Construction phase?
- Pre-design
- Design (Correct answer)
- Occupancy & Operations
- Acceptance
Correct answer: Design
The five phases in order are Pre-design, Design, Construction, Acceptance, and Occupancy & Operations; Design immediately precedes Construction.
Question 7: What is a key CxA deliverable at the end of the Acceptance Phase according to ASHRAE Guideline 0?
- Owner's Project Requirements document
- Final Commissioning Report (Correct answer)
- Commissioning Plan
- Basis of Design update
Correct answer: Final Commissioning Report
The Final Commissioning Report, summarizing all Cx activities, test results, and resolved issues, is the primary CxA deliverable at acceptance phase completion.
