Z--PECO - REPLACE SIDING AND FOUR HVAC UNIT

The National Park Service is issuing an RFQ for construction services at Pecos National Historic Park to remove and replace exterior siding, install a custom storm door, and replace four mini‑split HVAC units. The scope includes: • Removal of existing siding and installation of new siding per specified materials and finishes. • Fabrication and installation of a custom‑fabricated, charcoal‑grey aluminum storm door (approx. 41” W × 79½” H) with steel hardware, tempered safety glass, keyed lock, and weather‑stripping. • Installation of four new split‑system HVAC units with no substitutions allowed; equipment must meet performance specs (brand not mandated). • Patching of wall openings in curatorial/artifact storage rooms using FRP panels or embossed white galvanized steel panels, with pop‑rivets, silicone caulking, and 2×4 blocking. • Installation of rigid XPS insulation (R‑25 minimum, flame spread < 25) and a vapor barrier. The contractor must verify dimensions and mounting prior to ordering, and comply with fire‑rating and finish‑color requirements.
