The document outlines the procedures for determining sole source acquisitions under the Simplified Acquisition Procedures (SAP) based on Federal Acquisition Regulation (FAR) guidance. It mandates that sole source contracts may only be pursued if a contracting officer substantiates that only one source meets the government’s requirements. The case presented involves Advantor Systems Corporation, which provides necessary monitors for the Base Defense Operations Center's closed circuit TV camera system. Due to the proprietary nature of Advantor's equipment and its exclusive connection to the existing Air Force network, no other vendors can offer a comparable solution. The justification for this sole source acquisition details Advantor’s unique authorization to manage its equipment and the absence of competition in the market at this time. It concludes with the statement that future acquisitions may not need to be sole source, reflecting ongoing market monitoring for potential alternatives. Overall, this determination memorandum illustrates the government's careful consideration in justifying sole source procurements while highlighting the importance of proprietary technology in defense operations.
