Description
The State of Washington’s Military Department is seeking qualified contractors to upgrade the HVAC system in Building 8 at Camp Murray. The scope requires complete removal of three existing split‑system heat pumps and installation of a Variable‑Refrigerant‑Flow (VRF) system, including three indoor units with electric duct heaters and a single outdoor unit, as well as enlargement of the mechanical mezzanine access and provision of a pull‑down ladder. The project also entails demolition of existing mechanical and electrical components, coordination of conduit revisions, and installation of a temporary construction barrier to maintain site security and environmental controls.
• Remove existing split‑system heat pumps, air‑handling units, outdoor condensers, economizer dampers, and associated controls.
• Install a VRF system (3 indoor units + 1 outdoor unit) with electric duct heaters, and modify mezzanine access (new pull‑down ladder, enlarged opening).
• Perform mechanical, electrical, and structural demolition; install temporary barriers (½‑in. plywood, 6‑mil Visqueen, HEPA filtration); reroute conduits (2 × 1‑in. conduits with 3 #8 + #8 G conductors).
• All work must comply with Washington prevailing‑wage rates, “no substitutions” clause, and federal funding special conditions.
