This is a sources-sought notice for market research only, not a solicitation, and no contract will be awarded directly from responses. The anticipated firm-fixed-price, non-personal services contract would require upgrading and reconfiguring electronic security systems—including access control, intrusion detection, badging workstations, SCIF-compliant locking hardware, doors, vehicle gates, and system integration—at Fort Stewart, Georgia 31314. Work must be FIPS 201-compliant and integrate with the government’s existing DAQ-based security infrastructure, with contractor personnel meeting Top Secret/SCI clearance and access requirements. The government is seeking capability statements to assess qualified businesses, relevant experience, and potential contract vehicles. Interested firms should review the full notice for detailed capability-response requirements.
