NIH/NICHD intends to award a sole-source, firm-fixed-price contract to Leica Microsystems Inc. for a PremiumCare service plan covering its Leica Stellaris system, including annual preventive maintenance, unlimited on-site repairs (excluding lasers unless separately quoted), prioritized critical response, OneCall technical support, remote monitoring, and firmware/software updates when available. Services must be performed by factory-trained and certified Leica field engineers using genuine OEM parts, with optional hardware upgrades, software licenses, accessories, training, and professional services available. The contract is structured as a base year plus four option periods from 01/01/2027 through 12/31/2031, and pricing must cover the base and all option periods. Performance is at NIH, 9000 Rockville Pike, Bethesda, MD 20892. The notice cites the Leica Stellaris system’s high cost (~$1.5 million) and high usage as reasons for OEM service coverage, and non-OEM offerors must demonstrate bona fide capability with descriptive literature and warranties.
