Summary

This is a Department of the Air Force Justification for Other Than Full and Open Competition document approving a limited source contract award. The Air Force Materiel Command (AMC), Contracting Activity 628 CONS/PKA, is awarding a contract to an authorized SiRcom service provider for maintenance and repair services of the Joint Base Charleston (JB CHS) Giant Voice System on an individual basis. The requirement is for a base plus four (4) option year contract that includes all management, tools, supplies, labor, transportation, supervision, emergency/on-call services, and other necessary items to support the system. The vendor must provide two (2) semi-annual Preventative Maintenance Inspections on 16 Giant Voice sirens and three (3) control points. Only SiRcom-certified technicians are authorized to perform services, and the anticipated cost for all option years is redacted.

The justification cites 10 U.S.C. 3204(a)(1) as the statutory authority, establishing that only one responsible source and no other supplies or services will satisfy agency requirements due to the proprietary nature of the SiRcom system. The rationale emphasizes that unauthorized providers would introduce unacceptable risk to this mission-essential system and that only certified technicians possess the necessary expertise. Market research identified multiple vendors with SiRcom certification; a Sources Sought notice was posted on March 16, 2026 (with responses due March 23, 2026) to continue monitoring market opportunities. Three vendors were confirmed as authorized SiRcom service providers, with one proceeding to award and two stating intent to obtain certification. The Contracting Officer (Terry G. Harrelson, 628 CONS/PKA) signed this justification on May 6, 2026.
