About this file
This is a Questions and Answers document for federal solicitation W50SLF26QA003, addressing contractor inquiries regarding HVAC cleaning and insulation work at JBPHH Building 3400. The document does not address required products or services but rather clarifies scope and specifications through six key Q&A items dated July 23 and August 4, 2026.
The primary clarifications establish that: (1) existing insulation specifications are documented in the B3400 Ground Floor HVAC complete drawings (Pages 7-9), with replacement insulation requiring equivalent or upgraded specifications; (2) ductwork drawings for all four Air Handler Units are contained in the 10-page complete drawing set (Pages 1-10); (3) building square footage can be calculated using the graphic bar scale provided in the drawing documentation; (4) leak inspection and repair costs totaling $75,000 (inspection at $25,000 and repairs at $50,000) must be included as a fixed-price bid item rather than a separate allowance, with the contractor responsible for all necessary repairs to achieve watertight conditions per PWS 5.4 Field Verification; (5) replacing all chilled water insulation (both supply and return lines for four ground floor AHUs) is acceptable and recommended to prevent compromised insulation; and (6) damage to ceiling tiles from leaks is outside contract scope, which is limited to HVAC cleaning, chilled water line repair, and insulation replacement per PWS 5.0 Requirements. The Q&A reinforces fixed-price bidding requirements and clarifies that architectural finish repairs are excluded from the awarded contractor's responsibilities.

PROJECT # KNMD260026
HVAC Cleaning & Insulation, JBPHH-HI Questions & Answers
Dated: 07/23/2026
1. Insulation Material Specification, Performance Work Statement states: "The new insulation shall meet or exceed the specifications of the original material and be installed in accordance with manufacturer recommendations to prevent condensation and thermal loss." Please confirm the existing insulation specification (type, R-value/thickness, manufacturer), and whether replacement insulation must match the existing or if an equivalent/upgraded spec is acceptable.
ANSWER: All available technical specifications, system parameters, and drawing details for the existing insulation can be found in the reference document titled "B3400 Ground Floor HVAC complete drawings" on Pages 7–9.
2. Ductwork Drawings, only one (1) drawing sheet was provided, covering 2 of the 4 units in this project. Please provide ductwork drawings for the remaining 2 units.
ANSWER: All available system data, ductwork configurations, and layouts for all four (4) Air Handler Units are included in the reference document titled "B3400 Ground Floor HVAC complete drawings" on Pages 1–10. The Contractor shall refer to this complete 10-page drawing set for the necessary system details.
3. Building Interior Square Footage, please provide the total interior square footage of the building.
ANSWER: The exact total interior square footage is not directly specified in the project documents. However, the reference document "B3400 Ground Floor HVAC Drawing Graphic Bar Scale drawings" contains the complete floor layout. While this layout does not list explicit dimensional measurements, it includes a graphic bar scale that the Contractor can use to calculate the square footage of the work zones.
Dated: 08/04/2026
4. Leak Repair: The Contractor shall inspect the chilled water lines for any leaks and perform necessary repairs to ensure the system is watertight before new insulation is applied.
a. The following scope is broad in terms of how many pipe leaks could be identified. Proposed means and method is to remove all insulation, isolate the chilled water flow to its respective air handler and allow piping to dry.
i. Is it acceptable to qualify labor and materials for this task? $25,000.00 for leak inspection and $50,000.00 on leak repairs. If additional labor and materials are needed a ROM will be provided prior to performing the add.
ANSWER: No. Per PWS 5.4 Field Verification, the contractor is responsible for inspecting the site and verifying all conditions before submitting a bid. The total cost for all repairs must be included in the fixed-price bid, as it does not permit this required work to be treated as a separate budget or allowance. In PWS 5.2 Leak Repair, defines the scope as performing all "necessary repairs to ensure the system is watertight," reinforcing that the contractor is responsible for including what is needed to make the system work in their bid.
5. Insulation Replacement: Remove and replace all damaged or degraded insulation on the chilled water lines serving the four (4) AHUs on the ground floor. This includes both Chilled Water Supply (CWS) (if applicable) and Chilled Water Return (CWR) lines.
a. The extent of damaged or degraded insulation is unknown.
i. It is recommended to replace all insulation to avoid existing insulation from compromising new insulation.
ANSWER: Agreed. Per PWS 5.2 Insulation Replacement, requires the contractor to remove and replace all damaged or degraded insulation. Replacing all insulation is consistent with this.
6. Ceiling:
a. Ceiling tiles were visibly damaged by leaks during the site visit.
i. Is it the awarded contractor’s responsibility to replace damaged sections or tiles.
ANSWER: No. Per PWS 5.0 Requirements, the work is limited to HVAC cleaning, chilled water line repair, and insulation. The PWS does not specify the repair or replacement of any architectural finishes, such as ceiling tiles.
