Question Document 1.0 W912J2-26-R-A011 Repair Airlfield Lighting System 14Jul26.docx

This is a Questions and Responses document for Solicitation W912J2-26-R-A011 addressing clarifications on roof insulation specifications for the Repair Airfield Lighting System project at Volk Field Air National Guard Base. The document addresses a single submitted question regarding conflicting insulation requirements noted across multiple drawing details and construction specifications for the standing seam metal roof vault.

The government's response clarifies that the authoritative insulation specification is found on the Overall Roof Plan, Detail 1/AS-101, which requires two layers of 2.6-inch polyisocyanurate insulation for the roof deck. The government indicates that blanket insulation specifications referenced in section 07 61 42 (Steel Standing Seam Roofing) are incorrect and should be disregarded in favor of the polyisocyanurate roof deck insulation detailed on the drawings. The government notes that the latest corrected drawing set labeled "March 6th, 2026 (Revised)" has been uploaded to sam.gov to resolve these inconsistencies. This clarification ensures contractors understand the precise insulation system required for this fixed-price construction contract valued between $10 million and $15 million, with a project duration of 510 calendar days.
