About this file
This document contains technical questions and answers related to a federal contract opportunity for infrastructure upgrades to an EHRM data center in Dublin, GA. The opportunity involves upgrading electrical and low voltage systems, installing new data cabinets and fiber infrastructure, and reconfiguring the data center into defined phases to maintain operations. Key project details include installing new UPS systems with a 10-minute runtime at 125% load, upgrading the fire alarm system, and relocating telecommunications equipment to a temporary location during construction. Contractors should include conduit pathways for low voltage cabling and plan to complete electrical and data transfers after hours to minimize impacts. The government will provide laydown areas and considers the superintendent eligible to also serve as the CQC and SSHO roles.
