B7115 ROOF SEALANT SOLICITATION QUESTIONS AND ANSWERS

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

Answer: 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.

Proposals should respond to the required materials of the SoW.

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

Answer: 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 roofsystem?

Answer: 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, orshould the contractor follow the coating manufacturer’s recommendations?

Answer: Primers may be required by manufacturer’s recommendations. It is recommended to follow all manufacturers’ 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 betterperformance, so long as the warranty and durability criteria match or exceed the specifiedsystem?

Answer: The Government will accept substitution requests and evaluate the proposed systemsagainst the published requirements of the prescribed system.

For the purposes of this solicitation, provide the materials required by the SoW.

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

Answer: 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?

28.Is it the responsibility of the roofing contractor to remove the roof top unit, install new metal curb, and reinstall the unit? Currently sitting on 4"x4" wood blocks.

Answer: The evap coolers are non-operational. Remove from the roof, and cap the associated duct work prior to their entry into the building. Ensure weathertightness.

29.Is there access to water on site or base?

Answer: There may be water hydrants on the exterior walls of B7115

30.Membrane Color: Membrane color selection will be made from manufacturer’s standard colors, the color chart to be submitted to the Contracting Officer. (Aluminized polyurea is gray/silver.) Will a 4"x4" sample satisfy this requirement?

Answer: A 4”x4” material sample provided in the material submittal process would suffice.

31.Have you considered changing the specification to a complete metal roof replacement rather than coating the existing 44–65-year-old R-panel roof with urethane after extensive surface preparation and repair? Given the age and degradation, full replacement may be more cost-effective in the long term.

Answer: for the purpose of this task order, provide SoW required materials

32. If the total cost can be kept within the stated magnitude of construction ($250,000–$500,000) and still include the binary urethane coating specifications, would you consider rewriting the specification to allow for full R-panel replacement in lieu of major surface preparation?

Answer: for the purpose of this task order, provide SoW required materials

33. If the above is acceptable, would you still require a reflective binary urethane coating (as specified in the SOW) on top of the new R-panels

Answer: for the purpose of this task order, provide SoW required materials

34. If full replacement is not acceptable, at what percentage threshold of deteriorated R-panels would you consider requiring total replacement

Answer: replacement of roof panels is not a part of this SoW

35. Pressure washing appears problematic given the roof condition and risk of interior leaks.

Would you accept low-pressure washing with surfactant and wire-brushing rusted areas in place of high-pressure washing?

Answer: The actual surface prep process is part of means and methods, and subject to contractor preference/determination. The requirement is for surface prep to meet manufacturer’s requirements. Yes, it would be acceptable to the Government, if acceptable to the product manufacturer.

36. Given that wire-brushing could lead to “burn through” of the metal substrate, would you prefer replacement of rusted and damaged panels instead of surface preparation in such cases?

Answer: panel replacement is not part of this SoW.

37. The skylight area shown in the plan set appears in photos to actually be R-panels installed over previous skylight openings. Can you confirm whether these are true skylights or simply metal panels covering former skylight holes?

Answer: The skylights are/were scheduled for replacement with metal panels by 7 CES prior to the start of this contract.. It is unknown to the Base Architect if this has yet to be accomplished.

38. The product specification repeatedly specifies an “aluminized” finish. Would you consider other reflective finishes (e.g., white or off-white) as acceptable alternatives, or is aluminized strictly required?

Answer: The SoW requirement is for Aluminized Polyurea.

39. Several evaporative coolers appear severely corroded. If they cannot feasibly be detached and reset due to their compromised condition, will you require their replacement?

Answer: The evap coolers are non-operational. Remove from the roof, and cap the associated duct work prior to their entry into the building. Ensure weathertightness.

40: Will you publish a copy of the sign-in sheet from the August 13, 2025, site visit?

Answer: Yes, it will be published with answers.

41. R-panel comes in varying corrugation profiles. Can you provide the depth of corrugation and the width of the valleys and ribs/crests for the specified R-panel roofing?

Answer: The site visit provided the opportunity to collect that specific information.

42. There appear to be two distinct sections of roofing: approximately 11,000 sq. ft. (older) and 7,000 sq. ft. (newer). Can you confirm that the larger section was built around 1960 and the smaller section was added in 1981?

Answer: Correct.
