3.4 PRE-FUNCTIONAL CHECKLISTS (PFCs)<br />
Palm Beach International Airport<br />
A. General. Pre functional checklists (PFCs) are important to ensure that the equipment<br />
and systems are completely installed and integrated with other building components and<br />
systems, hooked up and operational. It ensures that functional performance testing (indepth<br />
system checkout) may proceed without unnecessary delays. Each piece of<br />
equipment or assembly receives full pre-functional checkout. No sampling strategies are<br />
used. The pre-functional testing for a given system must be successfully completed prior<br />
to formal functional performance testing of the equipment or subsystems of the given<br />
system.<br />
B. The PFC’s are developed by the CA and provided to the CM. The CM determines which<br />
trade is responsible for executing and documenting each of the line item tasks and notes<br />
that trade on the form. Each procedure and associated forms may have more than one<br />
trade responsible for its execution.<br />
C. The PFCs shall be supplemented by the contractor to include start-up and static test<br />
documentation required by the design specifications and by the manufacturer for each<br />
piece of equipment.<br />
D. The CM shall maintain a “living” copy of the PFC for each piece of equipment. This copy<br />
of the PFC shall be located inside a clear vinyl envelope and be affixed to the associated<br />
piece of equipment. When this method becomes impractical the PFC shall be<br />
maintained in the associated CM field office and available for review at any time.<br />
E. The PFC review shall be completed by field survey of each piece of equipment by the<br />
CM representative and the installing contractor.<br />
F. The installing contractor shall provide the individual with specific knowledge of the<br />
installation of respective equipment for this review.<br />
G. CA will review completed PFC’s prior to execution of system FPT. The CA performs<br />
random verification of checklist items and makes recommendation to CM to proceed with<br />
FPT.<br />
H. CA reserves the right to witness any startup and preliminary equipment testing.<br />

3.5 FUNCTIONAL PERFORMANCE TESTS (FPTs)<br />
A. Objectives and Scope:<br />
Palm Beach International Airport<br />
1. The objective of functional performance testing is to demonstrate that each<br />
system is operating according to the documented design intent and Contract<br />
Documents. Functional testing facilitates bringing the systems from a state of<br />
substantial completion to full dynamic operation. Additionally, during the testing<br />
process, areas of deficient performance are identified and corrected, improving<br />
the operation and functioning of the systems.<br />
2. Each system will be operated through all modes of operation (including but not<br />
limited to occupied, unoccupied, part- and full-load, power failure, equipment<br />
failure, etc.) where there is a specified system response and which meets the<br />
design intent.<br />
3. The contractor responsible for the dynamic operation of a system shall<br />
demonstrate comprehensive functionality of that system. All contractors that<br />
have contributed to the installation of the same system may not be required to<br />
participate in the FPT activity but shall be required to be immediately available for<br />
reconciliation of issues that fall within their scope and responsibility during<br />
testing.<br />
B. Coordination and Scheduling:<br />
1. FPT is conducted following completion of PFCs and associated start-up<br />
procedures during the course of construction.<br />
2. When the contractor completes a system the contractor may submit PFC<br />
documentation and request review and initiation of FPT.<br />
3. Coordination and final scheduling confirmation of FPT shall occur during<br />
regularly scheduled Cx meetings and through regular communication between<br />
the CA and CM.<br />
4. All Cx activities shall be fully integrated into the project construction schedule.<br />
This includes milestone deadlines for completion of installation of major system<br />
components and durations for FPT of a system.<br />
5. The CM shall provide sufficient notice to CA regarding changes to the<br />
coordinated completion schedule for FPT.<br />
6. The CA will witness and document FPT of systems which were demonstrated by<br />
the CM or its sub contractor. Designated sub-contractor or vendor responsible<br />
for dynamic operation of a system or device shall demonstrate system<br />
functionality to CC.<br />
7. Functional and installation issues shall be posted to the Cx action list and<br />
correction shall follow protocol as described in the Cx plan.<br />
8. Each contractor shall comprehensively test all systems for which they are<br />
responsible to the satisfaction of the Owner.<br />
3.6 CORRECTIVE MEASURES<br />
A. Non-Conformance:<br />
1. The CA will witness and document the results of all functional performance tests<br />
using the specific functional checklist forms developed for that purpose. Prior to<br />
testing, these forms are provided to the CM and Subs for review.<br />
<strong>Terminal</strong> <strong>Cooling</strong> Tower and Chiller Replacement 01800-6 Task I–11–PBI-R-046<br />
Palm Beach County, Florida December 2011<br />
<strong>Permit</strong> <strong>Set</strong>
Palm Beach International Airport<br />
2. The CA will document the results of all FPT. Deficient or non-conformance<br />
issues shall be noted and reported by CA as an action list item.<br />
3. Corrections of minor deficiencies identified may be made during testing at<br />
discretion of CA. In such case, deficiency and resolution shall be documented on<br />
FTP form and to action list as a resolved issue.<br />
4. Every effort shall be made to expedite testing and minimize unnecessary delays,<br />
while not compromising the integrity of the test procedures.<br />
5. The CM shall respond in writing to the CA at least as often as commissioning<br />
meetings are being scheduled concerning the status of each apparent<br />
outstanding discrepancy identified during commissioning. Discussion shall cover<br />
explanations of any disagreements and proposals for their resolution.<br />
6. Deficiencies are handled in the following manner:<br />
a) When there is no dispute of deficiency and Sub-contractor accepts<br />
responsibility for remedial action:<br />
(1) CA documents deficiency. CA posts issue to action list. Subcontractor<br />
corrects deficiency and updates the Master Action List.<br />
(2) If required, the CM reschedules test with CA and Sub-contractor.<br />
New test time is posted to project schedule.<br />
b) When there is a dispute about a deficiency, regarding whether it is a<br />
deficiency or who is responsible:<br />
(1) CA documents deficiency and Contractors response and testing<br />
proceeds on subsequent test or systems. CA posts issue to action<br />
list and distributes to project team.<br />
(2) The CA and CM facilitate resolution of deficiency. Other parties<br />
are brought into discussions as needed. Final interpretive<br />
authority is with A/E. Final acceptance authority is with the<br />
Owner.<br />
(3) Once interpretation and resolution has been decided, appropriate<br />
party corrects deficiency, and CA is given notice to proceed with<br />
retest, if required. The CM and CA reschedule test. New test<br />
time is posted to project schedule.<br />
B. Cost of Retesting:<br />
1. Costs for Sub-contractor to recheck PFC or re-execute FPT, if they are<br />
responsible for deficiency, shall be theirs.<br />
2. Any required retesting by any contractor shall not be considered a justified<br />
reason for a claim of delay or for a time extension by the CM.<br />
C. Approval:<br />
1. CA notes each satisfactorily demonstrated function on test form. CA, CM, and<br />
D.O.A. provide formal approval of FPT after review.<br />
D. Failure Due to Manufacturer Defect:<br />
1. If any equipment fails to perform to the Contract Documents (mechanically or<br />
substantively) due to manufacturing defect, not allowing it to meet its submitted<br />
performance spec, all identical units may be considered unacceptable by the CM,<br />
the A/E, or the CA. In such case, the responsible Sub shall provide the Owner<br />
with the following:<br />
