The Defense Health Agency intends to award a firm-fixed-price, sole-source contract to Conexus Inc. for a turn-key Real Time Location System (RTLS) asset tracking solution supporting the 48th Medical Group Hospital at RAF Lakenheath, United Kingdom, and associated satellite facilities. The requirement includes active/passive RFID tags, fixed readers, mobile scanning carts, handheld scanners, enterprise server licensing, installation, bi-directional APSR (DMLSS/LogiCole) integration, and recurring software/system maintenance. The action is justified under only-one-responsible-source authority because Conexus is the sole proprietary provider of the Plexus Vision platform, which holds the active ATO on DoDIN/MedCOI and integrates with existing hospital wireless networks and DMLSS/LogiCole. The period of performance is 16 September 2026 through 15 September 2027 for the base period, with options extending through 15 September 2031 if exercised. The contracting activity is DHA HCD-SE / Branch 6 – Europe, Landstuhl, Germany.
