HVAC install at HOG canyon

The United States Geological Survey (USGS) Office of Acquisitions and Grants is seeking a contractor to replace the HVAC system at the Hog Canyon Microwave Radio Relay Site, a 192 square foot communications shelter located in San Miguel, San Luis Obispo County, California. The project requires comprehensive removal of the existing HVAC system and installation of a new system with specific environmental controls to maintain room temperature between 68-72°F and relative humidity of 44-55%, compatible with the Asentria SiteBoss 550 Remote Site Manager. Contractors must demonstrate experience with at least three comparable communications shelter HVAC system installations that have performed satisfactorily for a minimum of one year, and must be registered in California with a valid business license. The evaluation will use a best value determination considering firm fixed price, technical capability of personnel and equipment, and demonstrated experience. Questions were due September 18, 2025, at 12:00 PM PDT, with proposals due September 22, 2025, at 12:00 PM PDT via email to Contracting Officer Charlan Fejarang.

This procurement is set aside exclusively for small businesses under a firm fixed-price construction contract structure, with no incumbent contractor identified in the available documentation. The contract performance period spans from October 1, 2025, to June 30, 2026, though the actual installation work must be completed within 14 calendar days once commenced. The site presents unique logistical challenges as it is located on a private cattle ranch accessible only by unimproved dirt, grass, and gravel roads requiring 4x4 vehicle access, with work restricted to Monday through Friday during normal business hours (0700-1700) under USGS escort. The facility is an active microwave radio communications site operating RF transmissions in the 900 MHz, 4.7 GHz, and 5.8 GHz bands, requiring contractors to work around sensitive electronic equipment. The contractor must provide all necessary HVAC systems, components, tools, and accessories while ensuring complete removal of all debris from the property upon project completion.
