FIELD QUALITY CONTROL
**************************************************************************
NOTE: Include Section 15950, "HVAC
Testing/Adjusting/Balancing."
**************************************************************************
a.
Demonstrate compliance of HVAC control systems. Furnish
personnel, equipment, instrumentation, and supplies necessary to
perform calibration and site testing. Calibrate test equipment in
accordance with NIST standards. Ensure that tests are performed
or supervised by competent employees of the control system
installer or the control system manufacturer regularly employed in
testing and calibration of control systems.
b.
Testing shall include field tests and the performance verification
test. Field tests shall demonstrate proper calibration of
instrumentation, input and output devices, and operation of
specific equipment. The performance verification test shall
ensure proper execution of sequence of operation and proper tuning
of control loops.
c.
The plan for each phase of field acceptance testing shall be
approved in writing before beginning that phase of testing.
Furnish written notification of planned testing to Contracting
Officer at least 21 days prior to testing. Include proposed test
procedures with notification. The Contractor will not be allowed
to start testing without written Government approval of test
procedures. Test procedures shall consist of detailed
instructions for complete testing to prove the performance of
heating, ventilating, and air-conditioning system and control
system.
Include the following tests in test procedures.
d.
Submit original copies of data produced, including results of each
test procedure, to the Government at the conclusion of each phase
of testing. Tests are subject to supervision and approval by
Contracting Officer. Do not perform testing during scheduled
seasonal off-periods of heating and cooling systems.
3.3.1
Test Reporting
After completion or termination of field tests and again after the
performance verification test, identify, determine causes, replace, repair,
or calibrate equipment which fails to meet the specification; and deliver a
written report to the Government. The report shall document test results,
explain in detail the nature of each failure, and corrective action taken.
After delivering the performance verification test report, the Contractor
shall convene a test review meeting at the job site to present results and
recommendations to the Government. As a part of the test review meeting,
the Contractor shall demonstrate by performing appropriate portions of
field tests or the performance verification test that failures have been
corrected. Based on Contractor's report and test review meeting, the
Government will determine either the restart point or successful completion
of testing. Do not commence required retesting until after receipt of
written notification by the Government. At the conclusion of retesting,
repeat the assessment.
