3.3.6 Quality Assurance - COTR TAB Field Acceptance Testing

3.3.6.1 TAB Field Acceptance Testing

During the field acceptance testing, verify, in the presence of the COTR, random selections of data (water, air quantities, air motion, sound level readings) recorded in the TAB Report. Points and areas for field acceptance testing are to be selected by the COTR. Measurement and test procedures are the same as approved for TAB work for the TAB Report.

Field acceptance testing includes verification of TAB Report data recorded for the following equipment groups:

Group 1: All chillers, boilers, return fans, computer room units, and air handling units (rooftop and central stations).

Group 2: 25 percent of the VAV terminal boxes and associated diffusers and registers.

Group 3: 25 percent of the supply diffusers, registers, grilles associated with constant volume air handling units.

Group 4: 25 percent of the return grilles, return registers, exhaust grilles and exhaust registers.

Group 5: 25 percent of the supply fans, exhaust fans, and pumps.

Further, if any data on the TAB Report for Groups 2 through 5 is found not to fall within the range of plus 5 to minus 5 percent of the TAB Report data, additional group data verification is required in the presence of the COTR. Verify TAB Report data for one additional piece of equipment in that group. Continue this additional group data verification until out-of-tolerance data ceases to be found.

3.3.6.2 Additional COTR TAB Field Acceptance Testing

If any of the acceptance testing measurements for a given equipment group

SECTION 23 05 93 Page 16 is found not to fall within the range of plus 5 to minus 5 percent of the TAB Report data, terminate data verification for all affected data for that group. The affected data for the given group will be disapproved. Make the necessary corrections and prepare a revised TAB Report. Reschedule acceptance testing of the revised report data with the COTR.

3.3.6.3 Prerequisite for Approval

Compliance with the field acceptance testing requirements of this section is a prerequisite for the final Contracting Officer approval of the TAB Report submitted.

3.4 MARKING OF SETTINGS

Upon the final TAB work approval, permanently mark the settings of HVAC adjustment devices including valves, gauges, splitters, and dampers so that adjustment can be restored if disturbed at any time. Provide permanent markings clearly indicating the settings on the adjustment devices which result in the data reported on the submitted TAB report.

3.5 MARKING OF TEST PORTS

The TAB team is to permanently and legibly mark and identify the location points of the duct test ports. If the ducts have exterior insulation, make these markings on the exterior side of the duct insulation. Show the location of test ports on the as-built mechanical drawings with dimensions given where the test port is covered by exterior insulation.

8(a) MULTIPLE AWARD CONSTRUCTION CONTRACT, VARIOUS LOCATIONS, GUAM

QUESTION (Q)32: Reference RFP Part A, Section 00210 Evaluation Factors for Award, Paragraph 2.4.c(5) Factor 5 – Price. Are Offerors required to submit a detailed cost breakdown in addition to the Price Proposal Schedule in Exhibit D?

Answer (A)32: No, a detailed cost breakdown is not required or desired.

Q33: Reference RFP Part A, Section 00210 Evaluation Factors for Award, Paragraph 2.4.c(4) Factor 4 – Technical Approach to the Seed Project and RFP Part C Seed Project. Are Offerors required to provide temporary air-conditioning units for all rooms while performing the removal and installation of the new system?

A33: Yes, provide temporary portable AC for cooling the living/dining rooms and all bedrooms during construction when there is no cooling during installation. Refer to RFP Amendment 0004.

Q34: Reference RFP Part C Seed Project. The sample unit displayed a 60 AMP NEMA 4X disconnect switch. Are Offerors required to install the same type/capacity of disconnect switch for this project?

A34: Replace NEMA4X disconnect switches in accordance with the ACCU’s manufacturer’s electrical ratings requirements as required for each building unit type of equipment. For the 4-ton ACCUs, it’s anticipated that a 60 AMP NEMA 4X safety disconnect switch will be required along with the panel circuit breakers and wiring for the ACCU based on the manufacturer’s electrical ratings. This will be incorporated into the electrical shop drawings as required.

Q35: Reference RFP Part C, UFGS Specification Section 23 05 93, Testing, Adjusting, and Balancing for HVAC, Paragraph 1.3 Work Description. The work description is requiring Duct Air Leakage Testing (DALT) for new and existing HVAC ductwork system. DALT is normally performed on new duct system. If DALT is to be performed on the existing ductwork, all ceiling outlets will need to be removed, caped sealed and will require 24 hours for the seal to dry. In addition, branch duct will need to be exposed requiring ceiling boards to be removed, and duct insulation exposed along duct joints to determine location of leak if DALT does not meet SMACNA Leakage test tolerance. This is best to perform if building is not occupied due to the amount of work required on the removal of ceiling boards and capping of duct inlet. Please confirm inclusion of DALT so the contractor can consider the cost impact.

A35: Due to the highly intrusive nature of DALT testing and the down time required to perform this scope of work, DALT will be removed from the specifications and only certified Testing, Adjusting, and Balancing (TAB) is required for all units in compliance with only the TAB requirements specified in UFGS Section 23 05 93. Refer to RFP Amendment 0004.
