The Naval Surface Warfare Center Carderock Division intends to award a sole source, firm-fixed-price purchase order for emergency repairs, corrective and preventive maintenance, and annual calibration of specific Waters/TA Instruments laboratory equipment. Services must be performed by OEM factory-trained and certified engineers using genuine OEM parts to support active NAVSEA fleet programs. This is not a request for competitive quotes, but responsible sources may submit a capability statement demonstrating verifiable OEM authorization and direct access to proprietary parts and calibration protocols. Interested firms should assess internal capabilities or interest accordingly, as no budget amount or performance location has been specified in the notice.
