Question 1
During the pre-design phase of a 150,000-square-foot laboratory
facility with stringent biocontainment requirements, the Owner's
Project Requirements (OPR) document states an objective of
achieving Net-Zero Energy operational status while maintaining
strict ISO 7 negative pressure gradients. The Design Professional
submits a Basis of Design (BOD) that utilizes a standard variable air
volume (VAV) reheat system with energy recovery loops but lacks
explicit dynamic cascading pressure control sequences. As the
Commissioning Authority (CxA), what is your most appropriate
initial action?
A. Reject the Basis of Design immediately and request a formal
redesign utilizing a dedicated outdoor air system (DOAS) with dual-
wheel energy recovery.
,B. Formally document an issue in the Commissioning Logs
indicating that the BOD fails to reconcile with the OPR's safety-
critical pressure boundary mandates, and request clarification
from the design team. (CORRECT ANSWER)
C. Revise the Owner's Project Requirements to lower the Net-Zero
Energy target so that the design team can safely prioritize pressure
containment using the current BOD layout.
D. Proceed to the design development phase and plan to address the
dynamic cascading pressure control sequences during the
construction submittal review process.
Rationale: The ACG Commissioning Guideline dictates that the
CxA must validate that the Basis of Design (BOD) aligns with and
satisfies the Owner's Project Requirements (OPR) throughout the
design phase. When a critical discrepancy is identified—especially
one involving life safety or containment boundaries—the CxA must
formally document it as a design issue and seek reconciliation rather
than unilaterally changing documents or rejecting designs without
team collaboration.
Question 2
A large-scale healthcare facility is undergoing commissioning under
the 2026 ACG guidelines. The project is currently transitioning from
the design phase to the construction phase. The electrical contractor
submits submittals for the emergency standby diesel generators. The
,submittals match the nominal capacities specified in the design
documents, but the CxA notices that the submittals lack the required
remote annunciation panel connectivity for the nurse call system
integration. What is the CxA's primary responsibility?
A. Approve the submittals as they match the design documents and
note the omission for future coordination meetings.
B. Review the submittals against the OPR and commissioning
specifications, identify the discrepancy, and coordinate with the
design team and contractor for resolution. (CORRECT
ANSWER)
C. Reject the submittals and require the contractor to resubmit with
the correct panel connectivity without consulting the design team.
D. Accept the submittals and address the integration issue during
functional performance testing.
Rationale: The CxA is responsible for reviewing contractor
submittals during the construction phase to ensure they align with
the commissioning specifications and the OPR. When discrepancies
are identified, the CxA must coordinate with the design team and
contractor to resolve issues before they become costly field problems.
Question 3
, Which document defines the owner's expectations for system
performance and serves as the primary reference for all
commissioning activities throughout the project lifecycle?
A. Owner's Project Requirements (OPR) (CORRECT ANSWER)
B. Basis of Design (BOD)
C. Commissioning Plan
D. Systems Manual
Rationale: The Owner's Project Requirements (OPR) is the
foundational document that establishes the owner's expectations for
system performance, operational requirements, and acceptance
criteria. It serves as the primary reference for all commissioning
activities and is used to verify that the design and construction meet
the owner's needs.
Question 4
In the commissioning team selection process, which role is primarily
responsible for appointing the Commissioning Authority (CxA)?
A. The general contractor
