The National Institutes of Health intends to award a firm-fixed-price purchase order to Siemens Medical Solutions for a maintenance agreement covering a 3 Tesla Magnetom Prisma MRI scanner. This is a sole source action under FAR Part 6.302-1, as Siemens is considered the only responsible source capable of meeting the requirement. Interested small businesses may submit a written capability statement demonstrating their ability to perform the services. The Government will determine whether to compete the award based on responses, with award anticipated approximately five days after the notice.
