The Gaithersburg Site Effluent Treatment System on the NIST campus in Gaithersburg, Maryland, requires a complete rebuild of its internal components due to severe corrosion and structural failure, including a detached floor support, inoperable safety systems, and seized equipment. The project involves replacing the entire floor, support members, safety blowers, heater, stir/agitation motor, pH monitoring probes, epoxy lining, lighting, and all explosion-proof electrical wiring. The period of performance is estimated at 200 days from the Notice to Proceed. No specific budget amount is mentioned. This opportunity is for a complete renovation to restore operational, regulatory, and life safety compliance.
