This is a Request for Information (RFI) document providing clarifications and responses to vendor inquiries regarding the Lyndon B. Johnson (LYJO) Historic Structures Reroof Project, Solicitation 140PS126Q0036. The RFI closes on August 7, 2026 at 2:00 PM CDT and addresses critical specifications for the reroofing work.

The primary clarifications address material substitutions, decking requirements, and warranty specifications. Substitutions to the specified DaVinci synthetic shake/shingle roofing material are permitted provided they meet Class A fire rating requirements and match the weathered cedar shake appearance of the existing roofs being replaced. The NPS will evaluate alternative suppliers through the submittal process. Solid deck installation is not required, not specified in bid items or drawings, and is unwanted for these historic structures; decking is mentioned only in reference to protection membrane application. For warranty purposes, a peel-and-stick ice and water shield is required, though a 50-year warranty is not being mandated. The work encompasses removal and reinstallation of wood shingles, structural repairs to wood joists and purlins, and installation of new synthetic shake/shingle roofing at multiple historic structures including the Bruckner Barn, Stubbs Cooler House, Boyhood Home Barn and Smokehouse, and Settlement Cabin (as bid option). Lightning protection removal, reinstallation, and new installations are also included. The contracting officer is Ruth Pagan (ruth_pagan@ios.doi.gov), and proposals must be submitted electronically by August 7, 2026 at 2:00 PM CDT.
