using single point measurement of entering and leaving wet and dry
bulb temperatures; the calculations shall be submitted with the
coil reports.
]3.2.8
Workmanship
Conduct TAB work on specified HVAC systems until measured parameters are
within plus or minus 10 percent of the design values, that is, the values
specified or indicated on the contract documents.
3.2.9
Deficiencies
Strive to meet the intent of this section to maximize the performance of
the equipment as designed and installed. However, if deficiencies in
equipment design or installation prevent TAB work from being accomplished
within the range of design values specified in the paragraph entitled
"Workmanship," provide written notice as soon as possible to the Contractor
and the Contracting Officer describing the deficiency and recommended
correction.
Responsibility for correction of installation deficiencies is the
Contractor's. If a deficiency is in equipment design, call the TAB team
supervisor for technical assistance. Responsibility for reporting design
deficiencies to Contractor is the TAB team supervisor's.
3.2.10
Data From TAB Field Work
**************************************************************************
NOTE: Choose one of the options below.
**************************************************************************
**************************************************************************
NOTE: Option 1: Normally, use the following
paragraph, which requires two separate trips within
a season to the contract site by the TAB field team
(the first for the TAB field work, the second for
the TAB quality assurance work) with the certified
TAB report submitted between the trips. This is
intended to give the design engineer time to review
the certified TAB report before the quality
assurance field check of that report is conducted.
**************************************************************************
[After completion of the TAB field work, prepare the TAB field data for TAB
supervisor's review and certification, using the reporting forms approved
in the pre-field engineering report. Data required by those approved data
report forms shall be furnished by the TAB team. Except as approved
otherwise in writing by the Contracting Officer, the TAB work and thereby
the TAB report shall be considered incomplete until the TAB work is
accomplished to within the accuracy range specified in the paragraph
entitled "Workmanship."]
**************************************************************************
NOTE: Option 2: Use the following paragraph when
the contract site is remote or the HVAC system is
simple, and the specifier wants to reduce to one the
number of trips to the contract site by the TAB
field team within a season. (TAB field work and TAB
quality assurance accomplished in same trip).
