The NIH Office of Research Services in Poolesville, Maryland requires custom fabrication, delivery, and installation of freestanding animal housing rack systems to replace existing hanging cage infrastructure in Building 103, while maintaining housing capacity for at least 32 primates per holding room. The racks must be compatible with existing Lab Products/Harford primate hanging cages, fit existing facility doorways, and include features such as a drinking-water delivery system, removable waste pans, and casters rated for high-temperature sanitation. Offerors must provide a government-approved prototype before full production, followed by final installation, operational testing, user training, and documentation. The award will be a single firm-fixed-price contract made on a best-value basis considering technical approach, relevant past performance, and price. Performance will occur at the NIH DVR facility in Poolesville, Maryland, with delivery, installation, testing, and training completed within the period specified in the resulting award.
