This is a Notice of Intent to award a sole-source, firm-fixed price contract to Philips North America LLC for maintenance services on a specific Philips MRI scanner located at the Molecular Imaging Branch in Bethesda, Maryland. The period of performance includes a one-year base period starting May 10, 2026, and three one-year option periods extending through May 9, 2030. The government asserts that only the original equipment manufacturer (Philips) can provide the necessary proprietary service to maintain the equipment's calibration and performance for critical cancer research. While the notice states the government plans to award a contract within 30 days, it allows other vendors to submit a capabilities statement within 15 days to challenge the sole-source justification. Services will be performed on-site in Bethesda, MD.
