TVHS VAMC Air Handler Units Refurbishment

The Department of Veterans Affairs is seeking bids under Solicitation 36C24926Q0177, Amendment P00003, for the refurbishment of Air Handling Units (AHUs) at the Nashville VA Medical Center, with performance located in Fan Rooms 6, 11, 15, and for AHUs numbered 4, 24, 39, 40, and 41. This solicitation is a Service-Disabled Veteran-Owned Small Business (SDVOSBC) set-aside under NAICS code 238220, with proposals due by May 18, 2026, at 11:00 CDT to the Network Contracting Office 9 in Murfreesboro, Tennessee. The scope includes replacing coils with tight performance tolerances, upgrading fan motors to IEEE 841 severe-duty specifications, installing Danfoss VFDs exclusively, adding UV-C lighting systems operating at 254 nm with UL listing and safety interlocks, and insulating piping per VA Master Spec 23 07 11 with mandatory PVC jackets in high-moisture zones. All work must integrate with the existing Siemens DDC control system and comply with strict VA safety, infection control, and life safety protocols, including Lockout/Tagout (LOTO), Infection Control Risk Assessments (ICRA), and fire watch responsibilities if alarms are impaired for more than four hours. Work occurs during normal hours but requires after-hours and weekend access for critical areas, with no temporary HVAC performance compromise allowed during outages. The contract is Firm Fixed Price with no economic price adjustment, no payment for stored materials, and no sales tax exemption. Offerors must submit proposals electronically via Procore or an equivalent digital platform; email submissions are prohibited. Compliance requires adherence to VA-specific procedures, including the use of VA-approved Siemens vendors for BAS integration, verification of all on-site dimensions due to lack of as-built drawings, and submission of Test and Balance reports by AABC or NEBB-certified technicians with VA oversight. The Contractor must designate a Superintendent as a direct employee, use an empty energy engineer office as a temporary site office, and manage logistics around limited parking and slow badging processes. All inspections and acceptance occur on-site, with VA personnel including the COTR, Safety Officer, Infection Prevention lead, and Construction Safety Committee chair performing oversight. Contract performance is scheduled to begin July
