B7115 ROOF SEALANT SOLICITATION

AMENDMENT 01

QUESTIONS AND ANSWERS

1. Can the government clarify whether alternative roofing systems, such as Spray Polyurethane Foam (SPF), would be considered acceptable in place of the specified aluminized polyurea system?

(A) Any substitution requests need to be accompanied by technical information describing how the substitution exceeds the specification ASTM material testing results of polyurea. Compare and contrast the SoW required polyurea system vs the proposed substitute. How does the proposed substitute hold up to our specific climate and active airfield environment.

– If so, would approval from the building engineer be sufficient to initiate a substitution request?

– Approval from Base Civil Engineering and the Contracting Officer is required.

2. If SPF is allowed as an alternative, would the system need to meet the same 80-mil minimum dry film thickness requirement as the specified polyurea system?

(B) Application thickness may be system specific and would need to be evaluated by case.

3. What are the minimum R-value or energy efficiency expectations, if any, for the roof system?

(C) There are no expectations for the roof coating material to provide additional insulation properties to the facility

4. Is a primer required for the polyurea coating application on this R-panel metal roof, or should the contractor follow the coating manufacturer’s recommendations?

(D) Primers may be required by manufacturer’s recommendations. It is recommended to follow all manufacturer’s surface prep instructions to achieve best possible bond with the existing roof system.

5. Will the government entertain a formal request for substitution based on equal or better performance, so long as the warranty and durability criteria match or exceed the specified system?

(E) The Government will accept substitution requests and evaluate the proposed systems against the published requirements of the prescribed system.

6. Are there any historical concerns or specific reasons why polyurea was selected over other coating technologies for this facility?

(F) The prescribed system provides desirable characteristics that hold up well in our specific environment, including, but not limited to: durability, longevity, chemical resistance, extreme climate conditions, FOD resistance, and weather.

7. For the upcoming site visit scheduled on August 13, 2025, will technical personnel such as the building engineer or a roofing consultant be available on-site to answer specification or product substitution questions?

(G) Contracting officials and Base Engineering will be in attendance. While we will be present to observe and address general inquiries, the Government will not be recording questions during the site visit. To ensure fairness and transparency for all potential offerers, we request that you notate any and all questions you may have and submith them in writing. All submitted questions and their corresponding answers will be posted as an amendment to the solicitation on SAM.gov.

8. Would the government accept the addition of an Aliphatic Urethane topcoat over the specified 80-mil polyurea system in order to satisfy the 15-year warranty requirement?

(H) Yes, if this is a requirement of the manufacturer in order to achieve the required warranty, it would be allowed.
