SUMMARY
A. The purpose of the commissioning process is to provide the owner/operator of the facility with a
high level of assurance that the mechanical systems have been installed in the prescribed
manner, and operate within the performance guidelines set in the Contract Documents. The
Commissioning Authority shall provide the owner with an unbiased, objective view of the
system’s installation, operation, and performance. This process is not i ntended to take away or
reduce the responsibility of the design team or installing contractors to provide a finished
product. Commissioning is intended to enhance the quality of system start-up and aid in the
orderly transfer of systems for beneficial use by the owner. The Commissioning Authority will
be a member of the construction team, administrating and coordinating commissioning activities
with the design team, construction manager, subcontractors, manufacturers and equipment
suppliers.

MASTER FINDINGS LIST
A.
Commissioning Agent (CxA) conducts initial Field Installation Verification (FIV), Operational
Performance Test (OPT), or Functional Performance Test (FPT) inspection.
B.
All findings from these inspections are documented and are posted to the master findings list
and website within two business days.
C.
Construction Manager (CM) will regularly distribute findings list to contractors and will hold
contractor accountable to: 1.) correct any items and/or 2.) provide electronic responses for
each finding.
D.
Responsible contractor will correct finding(s) and provide written confirmation that the finding(s)
have/has been corrected. If finding was not corrected, contractor provides written explanation.
E.
Commissioning findings’ status may be considered during the pay application approval process.
Approval may be withheld due to unresolved findings and/or findings where written responses
have not been provided.
F.
CM provides responses back to CxA. All responses are updated to the Master Findings List.
23 0800-2
HVAC COMMISSIONING
G.
Once written responses are provided for each finding, the CxA will re-inspect. The contractor
will be back-charged at a rate not to exceed the CxA contract hourly rate for any finding(s) that
was/were reported to have been resolved and that are found to be unresolved upon reinspection.
H.
Status will be tracked for each finding and the Master Findings List will be updated accordingly.
I.
Once all findings have been resolved and the job is completed, a Final Report will be generated
and a final commissioning meeting will be held.
2.6
FIELD INSTALLATION VERIFICATION (FIV) / MANUFACTURER’S CHEC KLISTS
A.
The Commissioning Authority will complete the FIV for each piece of equipment prior to startup.
B.
The equipment manufacturers’ checklists must be completed by the installing contractor
reviewed by the Commissioning Authority before start-up can commence.
2.7
START-UP
A.
Start-up of major HVAC systems will be witnessed by the Commissioning Authority. The
appropriate contractors and/or manufacturer’s representative will be required on site to perform
start-up. No system will be started until the appropriate FIV ’s have been completed. No system
will be started until the Manufacturer’s checklists have been completed. Start -up will be
performed according to the Manufacturer’s recommended procedures. The Commissioning
Authority will visit the site to review completeness of installation in conjunction with progress
meetings prior to starting HVAC equipment.
B.
2.8
Construction team members involved in installation, fabrication, manufacture, control, or design
of equipment are required to be present at the time of start-up. A factory-authorized technician
will be on site to start equipment when required by the specifications. This will minimize delays
in bringing equipment on line and expedite acceptable functional performance in accordance
with the Owner’s Project Req uirements (OPR) and the Basis of Design (BOD).
CONTROLS MONITORING
A. Close monitoring of the Control Contractor’s progress will promote efficient coor dination of the
TAB work. The DDC Contractor will be expected to submit point-to-point checklists verifying
that his work has been completed and all systems are ready for TAB work and Functional
Performance Testing. Programming and graphics will be surveyed by the Commissioning
Authority for completeness and conformance with the Owner’s Project Requirements ( O PR), the
Basis of Design (BOD) and the owner’s scheduling requirements.
2.9
TAB MONITORING
A.
The preliminary TAB report set-up will be reviewed prior to HVAC equipment start-up, in order
to assure that the final TAB report format and content is acceptable.
B.
TAB work will be monitored so that any problems that prevent or hinder proper air and water
balance can be addressed and corrected with minimal delays. By addressing these problems
as quickly as possible, we can assure that functional performance testing and owner training will
take place on schedule.
C.
A pencil copy of the TAB report will be reviewed prior to submission of the final TAB report. A
TAB report approved by the Design Engineer of Record will be required before Functional
Performance Testing can be carried out. The Commissioning Authority will visit the site during
the TAB process as necessary to verify proper means and methods.

2.10
OPERATIONAL PERFORMANCE TESTS (OPT) AND FUNCTIONAL PERFORMANCE TESTS
(FPT)
A.
The Commissioning Authority will perform OPT’s a nd FPT’s based on the Owner’s Project
Requirements (OPR) and the Basis of Design (BOD). These tests will be completed for HVAC
systems and subsystems.
B.
Each major system will be tested. A random sample of each subsystem will be tested. This will
be coord inated and witnessed by the Commissioning Authority and the owner’s maintenance
staff. Witnessing the FPT’s will serve as a compliment to the O&M Training. No OPT’s or
FPT’s will be performed until the TAB report and the control contractor Point Installa tion
Verification Checklists have been submitted and reviewed by the Commissioning Authority.
C.
2.11
Off-season mode testing will be implemented as necessary to assure conformance with the
Owner’s Project Requirements (OPR) and the Basis of Design (BOD). Installing contractors will
be expected to participate as required by the project specifications.
BUILDING TURN-OVER / OWNER ORIENTATION / USER TRAINING
A.
The Commissioning Authority will assist contractors to prepare, coordinate and review O&M
manuals, working closely with each contractor to achieve specificity and completeness.
B.
The Commissioning Authority will review record drawings, working closely with each contractor
to achieve specificity and completeness.
C.
Owner training will be coordinated with the assistance of the Commissioning Authority. The
training will be provided by the installing contractor, or manufacturer’s representative, and
witnessed by the Commissioning Authority. This training should include both classroom training
and hands-on operational training. The owner may choose to videotape this training for future
use. The Commissioning Authority will visit the site during the Turn-Over and Training period to
assure that any on-going HVAC related problems are being addressed and corrected in a timely
and efficient manner.
D.
The Commissioning Authority will assist the owner/user with warranty issues.
E.
The Commissioning Authority will assist in the coordination of off-season testing, calibrating,
and servicing as specified in the contract documents.
2.12
WARRANTY REVIEW
A. The Commissioning Authority will participate in an 11 th month walk-through to observe the
operation of the HVAC system. This will include a review meeting with FMD, a discussion of
warranty issues, energy usage, maintenance practices, usage changes, and chronic problems,
as well as other issues affecting the owner and the operation of the HVAC systems.
