The Department of Defense, through the Naval Surface Warfare Center Carderock Division (NSWCCD), is seeking proposals for the procurement of RDS Legacy Probe Interface Cables. The primary objective is to acquire compatible interface cables that will connect the legacy Thermo Fisher Scientific Frisker Probe, DT-304/PDR, to the new Radiological Detection System (RDS), which is crucial for enhancing radiological detection capabilities. This procurement will result in a Single Award Firm Fixed Price (FFP) Indefinite Delivery Indefinite Quantity (IDIQ) contract with a five-year ordering period. Interested vendors must register in the System for Award Management (SAM) and the PIEE Solicitation Module to participate, and they can request additional attachments by contacting Melinda Havens at melinda.s.havens.civ@us.navy.mil. Proposals must be submitted electronically via the PIEE Solicitation Module by the specified deadline.
