The Department of Defense, through the Fleet Readiness Center, intends to award a sole source contract to Tescan USA Inc. for the maintenance coverage of specialized scanning electron microscopes, specifically the Tescan Vega II XMU and Tescan Mira-3 GMU. The procurement includes annual preventative maintenance and calibration services, as well as a critical hardware upgrade requiring OEM-level access to proprietary software and firmware, which only Tescan USA can provide. These instruments are essential for the Materials Engineering Laboratory's operations, and using a third-party vendor could jeopardize system integrity and performance. Interested parties may submit capability statements within three calendar days of this notice, with Brandon Fabricante as the primary contact at gregory.b.fabricante2.civ@us.navy.mil for further inquiries.
