The Shiprock Service Unit (SRSU) requires a design-build solution to replace existing proximity card access equipment with new, enterprise-grade PIV card access control systems across three facilities in New Mexico, Arizona, and Utah. Approximately 50 proxy card access devices are currently deployed across the Service Unit. No specific budget amounts or submission timelines are mentioned in the description. The location for performance of services is the SRSU facilities, including Northern Navajo Medical Center, Four Corners Regional Health Center, and Dzilth-Na-O-Dith-Hle Health Center. This opportunity involves upgrading security access systems for the largest geographical service unit of the Navajo Area Indian Health Service.
