The National Institutes of Health intends to negotiate a sole-source, firm-fixed-price purchase order with Providence St. Patrick Hospital in Missoula, Montana, for Regional Referral Hospital Care and Isolation Unit services supporting NIH Rocky Mountain Laboratories (RML) in Hamilton, Montana. The contractor must provide 24/7/365 infectious disease specialist consultation and activate the Care and Isolation Unit within no more than six hours of request for RML personnel potentially exposed to high-risk pathogens. The unit must be at a Regional Referral Hospital within 75 miles of RML and be capable of negative-pressure clinical evaluation and full standard intensive care for at least 3 days (72 hours). The stated period of performance is 10/29/2026 to 03/28/2026, and the services are required for compliance with a federal lawsuit settlement agreement and federal select agent regulations. This is a Notice of Intent, not a competitive solicitation, and NIH states that Providence St. Patrick Hospital is the only facility within the required radius that can provide these specialized services; qualified sources may submit capability statements.
