3. Only individuals that have direct knowledge and witnessed that a line item task on the prefunctional checklist was actually performed shall initial the item as complete. It is not acceptable for witnessing supervisors to fill out these forms.

4. The Subs shall clearly list any outstanding items of the initial start-up and prefunctional procedures that were not completed successfully, at the bottom of the Prefunctional Checklist form or on an attached sheet.

5. The installing Subs or vendors shall correct all areas that are deficient or incomplete in the checklists and tests in a timely manner, and shall notify the CxA as soon as outstanding items have been corrected and resubmit an updated start-up report and a Statement of Correction on the original non-compliance report or as a response to the commissioning issues log.

6. Items left incomplete, which later cause deficiencies or delays during functional performance testing may result in back charges to the responsible party. Refer to Part

3.7 herein for details.

The CxA will schedule functional tests through the GC and affected Subs. The CxA shall direct, witness and document the functional performance testing of all equipment and systems. The Subs shall execute the tests.

1. Functional performance testing is conducted after equipment testing and startup has been satisfactorily completed.

2. The air balancing and water balancing is to be completed before functional performance testing of air-related or water-related equipment or systems.

3. Testing proceeds from components to subsystems to systems. When the proper performance of all interacting individual systems has been achieved, the interface or coordinated responses between systems can be checked.

4. Resolution Retesting will be scheduled after documented confirmation (controls trending, photograph, or completed work order form) that the issue has been resolved.

GENERAL COMMISSION REQUIREMENTS 019113 - 11

D. Execution of Functional Performance Testing. The CxA shall direct, witness, and document Functional performance testing. Each system should be operated through all modes of operation (seasonal, occupied, unoccupied, warm-up, cool-down, part- and full-load) where there is a specified system response. Verifying each sequence in the sequences of operation is required. Sample methods may be permitted as described in the Commissioning Plan.

E. Deficiency Resolution The CxA will document and recommend solutions to issues discovered during equipment installation and functional performance testing, however the burden of responsibility to solve, correct and demonstrate resolution of identified issues is with the GC, Subs and/or A/E.

3.6 DOCUMENTATION, NON-CONFORMANCE AND APPROVAL OF TESTS

A. Documentation. The CxA shall witness and document the results of all functional performance tests. The CxA will include the completed functional test procedures in the final commissioning report.

B. Non-Conformance.

1. All deficiencies or non-conformance issues shall be noted and reported on the issues log.

If there is a dispute about a deficiency, regarding whether it is a deficiency or who is responsible, the issue will be discussed at the commissioning meeting and the general contractor shall be responsible for delivering an operational system that is compliant with design documents. Final interpretive authority is with the A/E. Final acceptance authority is with the owner.

2. The CxA will record the results of the functional test on the test form, and final results will be documented on the test form upon successful retesting.

3. Corrections of minor deficiencies identified may be made during the tests at the discretion of the CxA. In such cases the deficiency and resolution will be documented on the issues log.

4. Every effort will be made to expedite the testing process and minimize unnecessary delays, while not compromising the integrity of the procedures. However, the CxA will not be pressured into overlooking deficient work or loosening acceptance criteria to satisfy scheduling or cost issues, unless there is an overriding reason to do so at the request of the owner.

5. Cost of Retesting.

a. The cost for the Sub to retest a prefunctional or functional test, if they are responsible for the deficiency, shall be theirs. If they are not responsible, any cost recovery for retesting costs shall be negotiated with the GC.

b. For a deficiency identified, not related to any prefunctional checklist or start-up fault, the following shall apply: The CxA and GC will direct the retesting of the equipment once at no “charge” for their time. However, the CxA’s and/or contractor’s time for a second retest will be charged to the GC, who may choose to recover costs from the responsible Sub.

c. The time for the CxA and GC to direct any retesting required because a specific prefunctional checklist or start-up test item, reported to have been successfully completed, but determined during functional performance testing to be faulty, will be backcharged to the GC, who may choose to recover costs from the party responsible for executing the faulty prefunctional test.

C. Failure Due to Manufacturer Defect. If 10%, or three, whichever is greater, of identical pieces (size alone does not constitute a difference) of equipment fail to perform to the Contract Documents (mechanically or substantively) due to manufacturing defect, not allowing it to meet its submitted performance spec, all identical units may be considered unacceptable by the CxA or OR. In such case, the Contractor and/or manufacturer shall replace or repair all identical items, at their expense and extend the warranty accordingly, if the original equipment warranty had begun. The replacement/repair work shall proceed with reasonable speed beginning within one week from when parts can be obtained

3.7 DEFERRED TESTING

A. Unforeseen Deferred Tests. If any check or test cannot be completed due to the building structure, required occupancy condition or other deficiency, execution of checklists and functional performance testing may be delayed upon approval of the OR. These tests will be conducted in the same manner as the seasonal tests as soon as possible. Services of necessary parties will be negotiated.
