The Department of Defense, specifically the Army, is soliciting proposals for sole-source semi-preventative maintenance and calibration services for the Marietta Digital X-Ray Machine located at the Corpus Christi Army Depot in Texas. The contract will require the selected vendor to provide essential services, including software updates, to ensure the machine's operational efficiency, which is critical for the Army's non-destructive testing capabilities. Due to the proprietary nature of the software required for the machine, Marietta Non-Destructive Testing, LLC is the only qualified vendor capable of fulfilling this contract, which spans from November 27, 2024, to November 26, 2025, with options for two additional years. Interested parties can contact Terry B. Clark at terry.b.clark4.civ@army.mil or by phone at 361-961-6489 for further details, with proposals due by November 26, 2024.
