The Department of Defense, Washington Headquarters Services (WHS/AD), on behalf of the Office of Military Commissions (OMC), proposes a sole-source bridge contract to General Dynamics Information Technology, Inc. (GDIT) for Case Analysts and Investigators Support Services. This extension of contract HQ0034-20-C-0082, valued at approximately $3.9 million, is necessary to avoid unacceptable delays in critical national security litigation as the current contract expires on May 10, 2023, and a long-term contract is not anticipated until November 2023. The justification cites GDIT's unique expertise, historical knowledge, and specialized security clearances, which are crucial for ongoing complex military commission cases such as the 9/11 case and the USS COLE bombing. Losing these experienced analysts would severely prejudice the government's prosecution efforts. Efforts to obtain competition included a 15-day Notice of Intent to Sole Source on SAM.GOV, which received no challenges. The government will ensure fair and reasonable pricing by comparing proposed costs to historical data and an independent estimate.
