The Department of Defense, specifically the 355th Contracting Squadron, intends to initiate a sole-source procurement for comprehensive preventative maintenance and repair services for six HAAS Brand CNC machines located at the 309th Aerospace Maintenance and Regeneration Group (AMARG) complex in Tucson, Arizona. The contractor will be responsible for providing all necessary tools, equipment, personnel, and management to ensure the effective maintenance of these machines, which are critical for aerospace maintenance operations. This procurement action is justified under FAR Part 13.106-1(b) as HAAS, Inc. is the original equipment manufacturer, and only they, along with their authorized distributor, can provide the required certified services. Interested firms wishing to contest this sole-source designation must submit an interest letter by March 17, 2025, to Contracting Officer Patricia Murray at patricia.murray.6@us.af.mil or by phone at (520) 228-3095, as the Government retains discretion on whether to proceed with competitive procurement based on the responses received.
