The Department of Transportation (DOT) intends to award a sole-source contract to Rapiscan Systems, Inc. for the maintenance and service of a Gemini X-ray system utilized in the security screening process at DOT Headquarters in Washington, D.C. This contract will cover all necessary parts and labor, with an estimated annual value of approximately $10,600, and is expected to span from April 1, 2025, to March 31, 2030. The Gemini X-ray system employs proprietary Z-Backscatter technology, which is critical for detecting low atomic number materials that may pose security threats, necessitating that only certified personnel perform maintenance to avoid warranty voids and ensure safety. Interested parties may submit a Statement of Qualifications to challenge the sole-source decision by April 25, 2025, and should direct inquiries to James Mowery at james.mowery@dot.gov.
