NIH’s Office of the Director intends to issue a non-competitive, firm-fixed-price purchase order to GE Precision Healthcare for preventive maintenance on two GE Healthcare TracerLab automated radiosynthesizers. GE Healthcare is the OEM and the only known source with the required technical expertise, factory-trained personnel, proprietary documentation and software, calibration procedures, and OEM parts. The acquisition will use streamlined commercial-item procedures and is not expected to exceed the simplified acquisition threshold. The applicable NAICS code is 811210, with a $34.0 million small-business size standard, and the requirement is not set aside for small business.
