(1) For purchases not exceeding the simplified acquisition threshold. (i) Contracting officers may solicit from one source if the contracting officer determines that the circumstances of the contract action deem only one source reasonably available (e.g., urgency, exclusive licensing agreements, brand-name or industrial mobilization).” X-ES is the Original Equipment Manufacturer (OEM) of the required chassis. X-ES does not have authorized resellers.

The Government does not possess the technical data package or intellectual property rights required to have this item manufactured by any other source. A new source would require significant time and investment to reverse-engineer, test, and receive source approval, which would result in unacceptable delays to the program. 4.

All responses received within five (5) business days of this notice's publication will be considered by the Government. Responses must demonstrate the capability to provide the exact part number listed above. 5. Disclaimer A determination by the Government not to compete with this proposed contract based on responses to this notice is solely within the discretion of the Government. The award will not be delayed for the purpose of evaluating new sources or pending source approval. It is estimated that an award will be made no later than 07 May 2026.
