The 410th Contracting Suppor Brigade/Regional Contracting Office- Miami in support of US Southern Command (USSOUTHCOM) located at 9301 NW 33rd Street, Doral FLorida 33172 will be issuing a Firm FIxed Price Contract for the purpose of ManagerPlus Lightning software. The software increases operational readiness with heightened visibility for all assets belonging to each of the ten (10) Caribbean Partner Nation (PN) Defense Force-Coast Guard(s), the Regional Security System supported by the Caribbean Security Basin Initiative (CBSI) Technical Assistance Field Team (TAFT) to assist their efforts in increasing the operational readiness of each PN's Coast Guard/Defense Force. The determination of this sole source procurement is in accordance with RFO FAR 12.102(a) , which states, for acquisitions valued at or below the simplified acquisition threshold (SAT), document the decision that only one source is available and the basis for the decision. Awarding this contract on a competitive basis to another vendor would cause potential mission failure as the CBSI TAFT partner nations are already using the ManagerPlus software.
