The sections selected will not exceed 20 percent of the total measured linear footage of the duct systems indicated as subject to duct air leakage testing. Sections of duct systems subject to duct air leakage testing will include 20 percent of main ducts, branch main ducts, branch ducts, and plenums for supply, return, exhaust, and plenum ductwork. It is acceptable for the entire system to be duct air leakage tested instead of disassembling that system in order to test only the 20 percent portion.

3.6.3 Duct Air Leakage Testing

The TAB Specialist must perform duct air leakage test on each system as selected by the Contracting Officer's Representative only after Duct Air Leakage Test Procedures have been submitted and approved. Complete duct air leakage test work within 48 hours after the particular ductwork was selected for testing by the Contracting Officer's Representative. Comply with approved Duct Air Leakage Test Procedures and SMACNA 1972 CD.

Provide all instruments, consumables, and personnel required to accomplish the Duct Air Leakage field work. Calibrate and maintain instruments in

SECTION 23 05 93.00 06 Page 7 accordance with manufacturer's written procedures. It is the contractor's responsibility to provide and install test ports as necessary for the duct air leakage tests. If the required conditions cannot be met during testing due to design or installation deficiencies, immediately notify the Contracting Officer's representative and provide written notice describing the deficiency and recommended corrections. The Contractor is responsible for correction of installation deficiencies.

3.6.4 Draft Duct Air Leakage Test Report

Following completion of the duct air leakage test work, prepare a Draft Duct Air Leakage Test Report using report forms shown in SMACNA 1972 CD.

The TAB Specialist must furnish the data required by the report forms.

Include a marked duct shop drawing identifying each section of duct tested with assigned node numbers for each section. Include node numbers in the completed report forms to identify each duct section. The TAB Specialist must certify the report. Include all calculations prepared in determining the duct surface of area of each duct test section. Include calibration curve for each of the test orifices used for testing. List instruments actually used to measure the data including the instruments unique identification number, calibration date, and calibration expiration date.

3.6.5 Duct Air Leakage Acceptance Test

In the presence of the Contracting Officer's Representative, verify, through retesting, 50 percent of the test data reported in the Draft Duct Air Leakage Test Report. If any data in the Draft Duct air Leakage Test Report is out-of-tolerance, perform acceptance testing on one additional duct section in the presence of the Contracting Officer's Representative.

If any of the duct sections checked for a given system are determined to have a leakage rate measured that exceeds the leakage rate allowed by SMACNA 1972 CD for an indicated duct construction class and sealant class, terminate data checking for that section. The associated draft report data will be disapproved. Make the necessary corrections and prepare a revised Draft Duct Air Leakage Test Report. Reschedule acceptance testing of the revised report data with the Contracting Officer's Representative.

At the sole discretion of the Government and with written concurrence from the Contracting Officer, the Contracting Officer's Representative may witness 100 percent of the Duct Air Leakage Tests in order to eliminate the requirement for Duct Air Leakage Acceptance Testing. In such a case, the Draft Duct Air Leakage Test Report serves as the Final Duct Air Leakage Test Report.

SECTION 23 05 93.00 06 Page 8 remaining. The TAB Specialist must also verify completion of all items necessary to perform TAB such as ductwork and piping ports, terminals, connections, etc. Provide a Systems Readiness Check Report , signed by the TAB Specialist, that certifies that all work necessary to perform TAB field work has been completed and includes checklists used to verify completion.

3.8 TESTING, ADJUSTING, AND BALANCING

3.8.1 Preliminary Procedures

Begin testing, adjusting, and balancing field work only after TAB Schematic Drawings and Report Forms, TAB Procedures, the Final Duct Air Leakage Test Report, the Building Air Barrier Air Leakage Test and Diagnostic Test Reports, and the Systems Readiness Check Report have been submitted and approved. It is the responsibility of the contractor to provide and install test ports as necessary for the TAB field work.

3.8.2 TAB Field Work

Test, adjust, and balance the HVAC systems until measured air and water flow rates are within plus or minus 5 percent of the design flow rates as specified or indicated on the contract documents. Test, adjust, and balance outdoor air supply flow to plus 10% and minus 0% percent and exhaust flow to plus 0% and minus 10% of design flow rates specified or indicated on the contract documents. Adjust balancing valves, dampers, and sheaves and change out fan sheaves and fan impellers as necessary to obtain the specified or indicated air and water flow rates. Comply with the requirements of the TAB Standard except as supplemented and modified by this section. Where possible, use "industry standard" adjusting and balancing techniques which would result in the greatest energy savings, such as adjusting the speed of a fan instead of throttling the flow.

Provide all instruments and consumables required to accomplish the TAB work. Calibrate and maintain instruments in accordance with manufacturer's written procedures. If the design flow rates cannot be attained due to design or installation deficiencies, immediately notify the Contracting Officer's representative and provide written notice describing the deficiency and recommended corrections. The Contractor is responsible for correction of installation deficiencies.

3.8.2.1 Units with Coils

Perform and report heating and cooling performance capacity tests for hot water, chilled water, DX, and steam coils for the purpose of verifying that the coils meet the indicated design capacity. Determine entering and leaving wet and dry bulb temperatures by single point measurement for units with capacities up to and including 7.5 tons or 90,000 Btu.

Determine entering and leaving wet and dry bulb temperatures by the average of multiple readings, in accordance with AABC MN-4, procedure "Coil Capacity Testing" for units over 7.5 tons or 90,000 Btu. Submit part-load data from the coil manufacturer converting test conditions to design conditions to verify coils meet intended design capacity in accordance with AABC MN-4, Procedure Coil Capacity Testing, Actual Capacity vs. Design Capacity.

The measurements will be recorded in the same manner as required for the TAB Report. If over 20 percent of the measurements selected by the COR for verification fall outside of plus to minus 5 percent of the Draft TAB Report data, the COR will select an additional ten percent for verification. If over 20 percent of the total tested (including both test groups) fall outside plus to minus 5 percent of the Draft TAB Report data, the TAB Report shall be considered invalid and all contract TAB field work shall be repeated beginning with the Systems Readiness Check. Correct all items outside of the required tolerance.

The Contractor shall be responsible for all necessary insulation repair following completion of TAB Verification.

3.11 Marking of Setting

Following approval of TAB Verification Report, the setting of all HVAC

SECTION 23 05 93.00 06 Page 10 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. Marking shall be visible following completion or repair of insulation.

3.12 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.
