The Defense Health Agency intends to award a sole-source contract to Instrumentation Laboratory SPA (Werfen) for preventive and corrective maintenance on government-owned Instrumentation Laboratory equipment at U.S. Naval Hospital Naples, Italy. The contractor must provide a full-risk maintenance plan, including annual preventive maintenance, unlimited on-site corrective repairs during normal working hours, replacement parts, travel, and labor, using OEM-qualified field engineers. The performance period is 1 November 2026 through 31 October 2027, with four 12-month option periods, and a maintenance schedule must be submitted within 15 days after a trouble call. This notice is not a request for competitive proposals, and competition is limited due to Werfen’s OEM-proprietary calibration keys and internal configuration modules.
