Schedule Requirements for HVAC TAB
The field work Section 15950N, "HVAC Testing/Adjusting/Balancing" shall be
broken down in the [Schedule of Prices and in the Construction Progress
Documentation][cost-loaded NAS] by separate line items which reflect
measurable deliverables. Specific payment percentages for each line item
shall be determined on a case by case basis for each contract. The line
items shall be as follows:
a.
Approval of Design Review Report: The TABS Agency is required to
conduct a review of the project plans and specifications to
identify any feature, or the lack thereof, that would preclude
successful testing and balancing of the project HVAC systems. The
resulting findings shall be submitted to the Government to allow
correction of the design. The progress payment shall be issued
after review and approval of the report.
b.
Approval of the pre-field engineering report: The TABS Agency
submits a report which outlines the scope of field work. The
report shall contain details of what systems will be tested,
procedures to be used, sample report forms for reporting test
results and a quality control checklist of work items that must be
completed before TABS field work commences.
c.
Season I field work: Incremental payments are issued as the TABS
field work progresses. The TABS Agency mobilizes to the project
site and executes the field work as outlined in the pre-field
engineering report. The HVAC water and air systems are balanced
and operational data shall be collected for one seasonal condition
(either summer or winter depending on project timing).
d.
Approval of Season I report: On completion of the Season I field
work, the data is compiled into a report and submitted to the
Government. The report is reviewed, and approved, after ensuring
compliance with the pre-field engineering report scope of work.
e.
Completion of Season I field QA check: Contract QC and Government
representatives meet the TABS Agency at the jobsite to retest
portions of the systems reported in the Season I report. The
purpose of these tests are to validate the accuracy and
f.
Approval of Season II report: The TABS Agency completes all
Season II field work, which is normally comprised mainly of taking
heat transfer temperature readings, in the season opposite of that
under which Season I performance data was compiled. This data
shall be compiled into a report and submitted to the Government.
On completion of submittal review to ensure compliance with the
pre-field engineering report scope, progress payment is issued.
Progress payment is less than that issued for the Season I report
since most of the water and air balancing work effort is completed
under Season I.
