The Defense Health Agency intends to award a sole source contract to Biomerieux Italia SPA for preventive and corrective maintenance on government-owned Biomerieux equipment at U.S. Naval Hospital Naples, Italy. The contractor will provide a full-risk maintenance plan covering annual preventive maintenance, unlimited corrective repairs during normal working hours, parts, travel, and labor, using OEM-qualified engineers. The period of performance is 01 November 2026 through 31 October 2027, with four 12-month option periods. The requirement is being sole sourced because OEM-proprietary calibration keys and configuration modules are not commercially distributed. Interested parties may submit a capability statement, but this notice is not a request for competitive proposals.
