PURPOSE/DESCRIPTION

The Government is conducting market research to identify potential sources that possess the production data/repair data, expertise, capabilities, and experience to meet qualification requirements for the Daily Freezer Replacement (Lay Up Room) on/for Tinker Air Force Base (AFB). The intent is for the Government to secure a one-year service contract for these services. Scope: The Contractor shall provide all labor, tools, equipment, test equipment, material, parts, quality control, transportation and inspection manuals necessary to perform replacing the existing refrigeration systems for two (2) walk in freezers located in the layup room in Building 9001, Post F-16 the Oklahoma City–Air Logistics Complex (OC-ALC). The equipment is listed in Appendix A (On-Base).

The Contractor shall be responsible for ensuring all services, parts and Original Equipment Manufacturer (OEM) components provided under this contract are in accordance with (IAW) the terms and conditions outlined herein, conform to the manufacturer’s equipment specifications and this PWS. The following descriptions are from the attached Performance Work Statement (PWS).

Requested Services: The Contractor shall replace the existing refrigeration systems for two (2) walk-in freezers. The new refrigeration systems must be fully compatible with the existing electrical setup, power requirements (Single‑phase, 208 V, 60 Hz), and freezer box panels (9 ft × 9 ft × 8 ft 5 in). No modifications are permitted to the freezer box panels or their disconnect boxes. The existing freezer box panels will be reused.

This is a turnkey project, requiring the contractor to provide all labor, materials, equipment, and services necessary to deliver fully operational systems capable of maintaining a –10°F setpoint.
