The $257,078.10 contract was awarded to Becton, Dickinson and Company (BD), the original manufacturer and sole authorized service provider for the specialized instruments. The services include preventative maintenance, software updates, technical support, and emergency on-site repairs within 48 hours to minimize downtime. This is a sole-source award, as BD is the only company with the ability to service the highly configurable, customized instruments. There is no set-aside designation for this commercial item contract.
