The Uniformed Services University of the Health Sciences (USUHS) intends to award a sole-source, firm-fixed-price contract to Signet Technologies, Inc. for the upgrade and installation of the Electronic Security System (ESS) at the Armed Forces Radiobiology Research Institute (AFRRI) in Bethesda, Maryland. This procurement aims to enhance the existing security infrastructure, as Signet is the original designer and installer of the system and holds proprietary rights, making them the only qualified provider for these upgrades. The initiative is crucial for maintaining operational readiness and ensuring the security of military health professionals' training environments. Interested vendors may submit proposals demonstrating their capabilities, although there is no obligation for USUHS to consider them; inquiries can be directed to Christopher White at christopher.white@usuhs.edu.
