Sole Source Justification Redacted (1).pdf

This is a Department of the Air Force Justification for Other Than Full and Open Competition (CUI document) dated March 2026.

The Air Force Material Command at Edwards AFB, California is seeking a sole source acquisition for a Siemens Building Management System (BMS) centralized air-gapped alarm notification cabinet. The requirement is for one cabinet located in the communications room adjacent to the Building Automation System front end, capable of monitoring up to 48 discrete alarm inputs representing up to 16 alarm points per building across 3 buildings. The system shall transmit alarm notifications using stacked auto-dialer devices capable of delivering prerecorded voice messages to designated phone numbers and must operate independently of the building network without requiring internet connectivity. Required hardware includes one Siemens PXC-series controller, relay expansion modules supporting 48 alarm inputs, one 24VDC power supply, six auto-dialer devices (8 inputs per device), UPS battery backup system, and internal wire management with labeling. All components must be mounted, wired, and tested within the cabinet assembly.

The justification for sole source procurement is based on 10 U.S.C. 3204(a)(1), citing that only one responsible source and no other supplies or services will satisfy agency requirements. Siemens is the sole source manufacturer with no resellers; the equipment is ancillary to the existing Siemens TSECMS contract FA930221D0007 and utilizes proprietary software and controllers that only Siemens specialists can service. The justification references previous awards FA930221D0007 and FA930216D0005 for related maintenance and support services. The contracting officer is responsible for determining fair and reasonable pricing in accordance with FAR Subpart 15.4. The government will continue evaluating opportunities to increase competition for future requirements, though the current specialized chamber design presents significant barriers to alternative solutions.
