Specialist determines during TAB Execution that any

3.5.4
TAB Verification
**************************************************************************
NOTE: Where, on projects with a small number of TAB
measurements, it is impractical to specify a
percentage of measurements to be verified, this
paragraph should be modified to specify the number
of measurements.
**************************************************************************
The TAB Specialist shall recheck ten percent of the measurements listed in
the Tab Report and prepare a TAB Verification Report. The measurements
selected for verification and the individuals that witness the verification
will be selected by the Contracting Officer's Representative (COR). The
measurements will be recorded in the same manner as required for the TAB
Report. All measurements that fall outside the acceptable operating range
specified shall be accompanied by an explanation as to why the measurement
does not correlate with that listed in the TAB Report and a description of
corrective action performed to bring the measurement into the specified
range. The TAB Specialist shall update the original TAB report to reflect
any changes or differences noted in the TAB verification report and submit
the updated TAB report. If over 20 [_____] percent of the measurements
selected by the COR for verification fall outside of the acceptable
operating range specified, the COR will select an additional ten [_____]
percent for verification. If over 20 [_____] percent of the total tested
(including both test groups) fall outside of the acceptable range, the TAB
Report shall be considered invalid and all contract TAB work shall be
repeated beginning with the Systems Readiness Check.
3.5.5
Marking of Setting
Following approval of TAB Verification Report, the setting of all HVAC
adjustment devices including valves, splitters, and dampers shall be
permanently marked by the TAB Specialist so that adjustment can be restored
if disturbed at any time.
3.5.6
Identification of Test Ports
The TAB Specialist shall permanently and legibly identify the location
points of duct test ports. If the ductwork has exterior insulation, the
identification shall be made on the exterior side of the insulation. All
penetrations through ductwork and ductwork insulation shall be sealed to
prevent air leakage or to maintain integrity of vapor barrier.
