Notice of Intent to Sole Source - Atlantic Diving Supply, Inc. - Increase ceiling of IDIQ

The Department of Homeland Security's Immigration and Customs Enforcement (ICE), Office of Acquisition Management, has published a Special Notice on February 5, 2026, announcing its intent to sole source a contract modification to Atlantic Diving Supply, Inc. This notice indicates DHS/ICE's plan to increase the ceiling on an existing single-award Indefinite Delivery, Indefinite Quantity (IDIQ) contract (70CMSD24D00000001) under the authority of FAR 6.103-1 and Class Deviation 25-11. The contracting action pertains to MAMMOTH, a web-based online ordering platform that supplies clothing, personal protective equipment, and tactical supplies to Homeland Security Investigations. The contracting officer has determined that Atlantic Diving Supply, Inc. is the only responsible source capable of satisfying agency requirements for this specialized platform.

This Special Notice is issued for informational purposes and does not constitute a request for quotation from other potential contractors. The deadline for this notice is February 11, 2026, providing industry participants with a six-day window to respond or lodge concerns. As a sole source procurement action under FAR 6.103-1, this opportunity is not open to competition, and the determination to proceed without competitive bidding remains within the sole discretion of the contracting officer. The MAMMOTH platform is the primary focus of this modification, which will expand the existing contract's ceiling to support continued procurement of specialized equipment and supplies for ICE's Homeland Security Investigations division. Interested parties may use this notice period to demonstrate why the sole source determination is inappropriate or to provide relevant information to the contracting officer.
