NRC Columbus - Mech Room Floor Repair and Sealing (see remarks)

The Columbus Mech Room Floor Seal and Epoxy Coat project, managed by Navfac Mid-Atlantic for the Department of the Navy, is a forecast requirement scheduled for funding in the second quarter of 2026. The primary objective is to remediate several cracks in the mechanical room floor that are currently allowing water to leak into the Marine Armory below, which poses a risk to the condition and readiness of stored weaponry. The scope of work includes performing necessary concrete patching to fill voids, verifying the operation and orientation of floor drains, and applying an epoxy seal coating to the entire floor, including all equipment pads and curbing. Following the application of the sealant, testing will be conducted to ensure the area is completely watertight and that no further leakage occurs into the armory. The project is categorized under NAICS code 238350 and will be performed at Great Lakes. Internal reviews from the APM, CRM, and RPM have been completed with no concerns noted, and it has been confirmed that the work does not affect any historic properties.
