This is an indefinite quantity contract for a 5-year base period with an estimated annual quantity of 40 units of a float piston manufactured under a specific part number by multiple approved sources. The procurement is unrestricted but requires access to unclassified DoD-restricted data, so contractors must be certified via DD Form 2345. First article testing is required, with first article units delivered 275 days after order, followed by a 180-day government testing/evaluation period, then production units delivered 275 days after first article approval. Regular production deliveries are 712 days after order, with FOB destination and inspection/acceptance at origin for production units (inspection at origin, acceptance at destination for first article). A reverse auction may be conducted, and offerors are encouraged to self-register in the ProcureX system.
