LMA Tech Trl HVAC Replacement

The Department of the Army Corps of Engineers Engineering District Walla Walla seeks to procure the supply, installation, and commissioning of new ductless heat pump systems to replace existing HVAC equipment at the Tech Section Office Building at Lower Monumental Lock & Dam in Kahlotus, Washington. The successful contractor must remove and properly dispose of existing outdoor condenser units, line sets, wire whips, and mounting pads in compliance with all applicable local, state, and federal regulations, while evacuating all refrigerant from existing indoor air handlers and capping line sets. Key contract requirements include adaptation or modification of existing drain lines and electrical wiring at no cost to the government, compliance with all Corps of Engineers and OSHA safety standards, building codes, electrical codes, and prevailing wage requirements, and delivery of complete Operation and Maintenance manuals. The contractor must be a licensed and bonded HVAC company with a minimum of ten years of experience installing and servicing commercial or industrial HVAC systems and must complete all work within four weeks of contract award. This is a total small business set-aside with a due date of March 17, 2026, and no solicitation is currently available, meaning this pre-solicitation notice provides advance notification of the upcoming formal solicitation.

The project encompasses three separate ductless heat pump system installations with specific performance requirements: a 4-ton system with four wall-mounted units for an open office area (minimum SEER2 rating of 22 and HSPF2 rating of 11), a 2-ton system with three wall-mounted units for offices and support rooms (minimum SEER2 rating of 22 and HSPF2 rating of 10), and a 1.5-ton system with one cassette unit for a conference room (minimum SEER2 rating of 19 and HSPF2 rating of 11). All systems must utilize R-454B refrigerant with variable speed rotary inverter compressors and include advanced features such as wireless remote controls, built-in base pan heaters, self-diagnostic systems with refrigerant leak detection, and automatic louver swing capabilities. Bid items are structured as lump-sum pricing for equipment, materials, installation, and commissioning for each of the three systems, with delivery FOB to Lower Monumental Lock and Dam. The contractor must provide a minimum one-year manufacturer's warranty on parts and labor and coordinate with the Contract Performance Specialist at least one week in advance for scheduling. No specific budget range or award value is indicated in this pre-solicitation notice, but contractors should note that existing electrical wiring and drain lines must be adapted or upgraded without additional cost to the government.
