Sole Source Justification for Digital Matrix Switch Hardware

This document is a Determination & Findings (D&F) justification for a sole source procurement at Edwards Air Force Base (AFTC/PZZF). The acquisition covers highly specialized Digital Matrix Switch hardware manufactured by Apogee Switches, including four 16-channel TTL input modules, one 16-channel analog input module, six 16-channel TTL output modules, one 16-channel analog output module, one switch chassis, one digital switch controller, and one remote control software package. The procurement is justified under RFO 8.401 and GSAR 538.7104-3(a) for FSS orders, citing that only one source is reasonably capable of providing these specific products.

The justification emphasizes that the specialized hardware must remain identical to existing legacy systems to ensure operational continuity, system interoperability, and compliance with established organizational support processes and maintenance procedures. The contractor's unique qualifications include compatibility with pre-vetted support software and documentation, as well as alignment with Information System Security Manager and Program Office Security approvals. The document notes that introducing non-standard hardware would require substantial engineering rework, custom software development, and extended operational downtime, along with security decertification risks. Related prior purchases were made under POs FA930224F0080, FA930224P0091, and GPC FA930223FG510. The determination is signed by Contracting Officer Dryer Susana (NH-IIII) and dated July 1, 2026.
