66--PO for One (1) 7T Gradient Coil Upgrade

The National Institutes of Health, through the Office of Logistics and Acquisition Operations, is procuring a single 7T MRI upgraded gradient coil to replace an existing unit at the Neurophysiology Imaging Facility in Bethesda, Maryland, that suffers from thermal instability, inadequate coolant flow, elevated temperatures, and imaging artifacts affecting high-resolution marmoset brain research. The coil must be mechanically compatible with the Bruker 7T/30 cm magnet, installable through the front bore, and feature a clear internal diameter greater than 17 cm to support existing experimental setups. It must interface seamlessly with the current Fujifilm/PCI DA 1500-1 gradient amplifier and 6-channel shim power supply, while achieving a minimum gradient strength of 450 mT/m and a slew rate of 1800 T/m/s with negligible eddy current effects to ensure data integrity in diffusion and functional imaging. Operational stability is required under existing thermal management conditions: 44 psi water pressure and 19°C coolant temperature via the triple loop heat exchanger. The contract is issued as a combined synopsis/solicitation for commercial items under FAR 52.212-4 and 52.212-5, with no additional contract requirements beyond standard commercial clauses. Offerors must submit proposals via SAM.gov by June 24, 2026, at 5:30 pm, including detailed pricing, delivery timeline, F.O.B. terms, product identifiers, and certifications, along with their Unique Entity Identifier, Taxpayer Identification Number, and business size certification. All respondents must maintain active registration in SAM.gov and include a completed FAR 52.212-3 form. Delivery is FOB destination to NIH/NIMH at 49 Convent Drive, Room B2-102, Bethesda, MD 20892. The award will be made based on best value, considering price, technical capability, past performance, delivery schedule, warranty, lifecycle cost, maintenance availability, and environmental or energy efficiency. The solicitation is unrestricted under NAICS code 811210, with no set-aside, and the Defense Priorities and Allocations System is not applicable.
