CHILLER PLANT COMMISSIONING REQUIREMENTS – AMENDMENT 0003

PART 1 - GENERAL

1.1 COMMISSIONING

A. Commissioning is a systematic process of confirming that all building systems perform interactively according to the NIST’s Program Requirements and the Basis of Design and continuing through construction, acceptance and the warranty period with actual verification of performance.

B. This project will have selected HVAC systems commissioned. The commissioning process will be directed by a Commissioning Authority whose services will be provided by the design build contractor.

C. The Commissioning Authority shall report to the project CO, COR and the design build contractor.

D. Commissioning during design is intended to achieve the following specific objectives:

1. Verify NIST’s Program Requirements and Basis of Design are clearly documented, and they meet NIST’s goals and objectives.

2. Provide Design Review during design efforts.

3. Verify commissioning for the construction phase is adequately reflected in the bid documents.

E. Commissioning during the construction phase of this project is intended to achieve the following specific objectives:

1. Provide direction for the commissioning process during construction, particularly providing resolution to issues and providing details not developed during design (ex.

scheduling, participation of various parties, lines of reporting and approvals, coordination, etc.)

2. Verify that applicable equipment and systems are installed properly and receive adequate operational checkout by installing contractors.

3. Verify and document proper performance of equipment and systems.

4. Verify that O&M documentation left on site is complete.

5. Verify that NIST’s operating personnel are adequately trained.

F. The CxA works with the contractor according to established protocols to schedule the commissioning activities. The CxA will provide sufficient notice to the contractor and Owner for scheduling commissioning activities. Meanwhile, the CxA will integrate these activities into the master construction schedule. All parties will address scheduling problems and make necessary notifications in a timely manner in order to expedite the commissioning process.

G. The following narrative provides a brief overview of the commissioning tasks during construction and the general order in which they occur.

1. Commissioning during construction begins with a Commissioning Kick-Off Meeting –

Construction Team conducted by the CxA where the commissioning process is reviewed with the commissioning team members.

2. Additional meetings will be required throughout construction, scheduled by the CxA with necessary parties attending, to plan, scope, coordinate, schedule future activities and resolve problems.

3. Equipment documentation is submitted to the CxA through the submittal process, including detailed start-up procedures.

4. In general, the checkout and performance verification proceeds from simple to complex;

from component level to equipment to systems and intersystem levels with Prefunctional checklists being completed before functional testing begins.

5. The contractors, under their own direction, document and perform startup and initial checkout. The CxA documents that startup was completed according to the approved plans, when contracted. This may include the CxA witnessing start-up of selected equipment, if contracted.

6. The CxA verifies installation integrity thru the use of checklists.

7. The CxA develops specific equipment and system functional performance test procedures. The contractors review the procedures.

8. The procedures are executed by the contractors, under the direction of, and documented by the CxA.

9. Items of non-compliance in material, installation or setup are corrected at the contractor's expense and the system retested.

10. The CxA reviews the O&M documentation for completeness.

11. Commissioning is completed before Substantial Completion, whenever possible.

12. The CxA reviews and pre-approves the training plan provided by the contractors.

13. The contractors coordinate and provide training via qualified instructors.

14. Training occurs.

15. NIST verifies that training has occurred and provides a written statement that training has occurred.

16. Deferred testing is conducted, as specified or required

The Commissioning Authority shall complete the Pre-Functional checks in the field, with assistance from the installing Contractors (where necessary).

B. The installing contractors, under the direction of the CxA, shall perform Functional Performance

Testing of systems and sub-system performance after Pre-Functional checks have been com-pleted and all outstanding issues resolved.

C. The installing contractor will perform tests specified in Division 1 commissioning process activity

Sections and other sections specifying testing procedures according to approved testing proce-dures.

1. Verify and test performance using actual conditions whenever possible.

2. Simulate conditions by imposing an artificial load when it is not practical to test under ac-tual conditions. Set and document simulated conditions and methods of simulation. After test, return settings to normal operating conditions.

3. Alter set points when simulating conditions is not practical.

D. The CxA shall witness and document the results of all functional performance tests using the specific procedural forms developed for that purpose. Prior to testing, these forms are provided to the Contractors for review and comment.

E. deficiencies/non-conformance

1. The CxA will record the results of the functional test on the test form. All deficiencies or non-conformance items shall be noted and reported to NIST and Contractors on a stand-ardized form.

2. Corrections of minor deficiencies identified may be made during the tests at the discretion of the CxA.

3. Every effort will be made to expedite the testing process and minimize unnecessary de-lays, while not compromising the integrity of the procedures.

4. As tests progress and a deficiency is identified, the CxA discusses the issue with the ex-ecuting contractor.

5. When there is no dispute on the deficiency and the contractor accepts responsibility to correct it, the CxA documents the deficiency and the contractor’s response and intentions or corrections. The CxA and contractor then proceed to another test or sequence. Once the contractor corrects the deficiency, the test is rescheduled and repeated in the antici-pation of correct operation or function. If a deficiency is identified, the cost of retesting will be as per section 3.7.

6. When there is a dispute about a deficiency, regarding whether it is a deficiency or who is responsible, the CxA documents the deficiency and the contractor’s response. The defi-ciency is then forwarded to parties assumed to be responsible for the deficiency. Resolu-tions are made at the lowest management level possible. Other parties are brought into the discussion as needed. Final interpretive authority is with shall be NIST. Final ac-ceptance authority is with NIST and CxA. The CxA will then document the resolution process. Once the interpretation and resolution have been decided, the appropriate party corrects the deficiency. The CxA then reschedules the test as stated in the section above. Costs of retesting are as stated below in the applicable section.

F. Failure due to Manufacturer Defect

1. 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 sub-stantively) due to manufacturing defect, not allowing it to meet its submitted performance spec, all identical units may be considered unacceptable by the CM/GC, CxA or Owner.

In such case, the Contractor shall provide NIST with the following.

2. Within one week of notification from the contractor or Owner, the Contractor or manufac-turer’s representative shall examine all other identical units making a record of the find-ings. The findings shall be provided to the contractor or Owner within two weeks of the original notice.

3. Within two weeks of the original notification, the Contractor or manufacturer shall provide a signed and dated, written explanation of the problem, cause of failures, etc. and all pro-posed solutions which shall include full equipment submittals. The proposed solutions shall not significantly exceed the specification requirements of the original installation.

4. The contractor, CxA or Owner will determine whether a replacement of all identical units or a repair is acceptable.

5. Two examples of the proposed solution will be installed by the Contractor and the Con-tractor will be allowed to test the installations for up to one week, upon which the CxA or owner will decide whether to accept the solution.

6. Upon acceptance, 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.

G. Approval

H. Deferred Testing

1. Unforeseen Deferred Testing – If any check or test cannot be completed due to the build-ing structure, required occupancy condition or other deficiency, execution of checklists and functional testing may be delayed upon approval of NIST. These tests will be con-ducted in the same manner as the seasonal tests, as soon as possible. Services of nec-essary parties will be negotiated.

2. Seasonal Testing - During the warranty period, seasonal testing (tests delayed until weather conditions are closer to the system’s design) shall be completed as part of this contract. The CxA shall coordinate this activity. Tests will be executed, documented and deficiencies corrected by the appropriate contractors, with facilities staff and the CxA wit-nessing.
