This is a 100% small business set-aside solicitation for a firm-fixed-price Indefinite-Delivery, Indefinite-Quantity (IDIQ) contract to provide medical laboratory testing services to the 172nd Medical Group. The contract will have a five-year ordering period, and services must be performed at a licensed facility within 30 minutes of the 172d Airlift Wing in the Jackson Metropolitan Statistical Area, available Sunday through Saturday from 0730 to 1600. The government will award using a best value trade-off process, with technical capability (including CLIA/CAP certification, turnaround time, and geographic accessibility) significantly more important than past performance and price. Offerors must propose pricing for all required tests, and orders under $25,000 will primarily be placed via Government Purchase Card. Proposals are due 60 days after the solicitation closing, and past performance within the last three years on similar multi-year contracts will be evaluated.
