About this file

Written by GovTribe AI · Sep 10, 2025

This is a set of design and engineering documents for the Substation A Repair project at Rock Island Arsenal, Illinois, prepared by the U.S. Army Engineering and Support Center. The project involves a comprehensive electrical infrastructure upgrade, including demolition of the existing substation, installation of new switchgear, electrical ductbanks, and associated infrastructure. Key components include a new 13.8kV switchgear system with multiple breaker configurations, electrical vault with cable trays, and provisions for future expansion such as battery energy storage and generator systems.

The project documents detail precise technical specifications for electrical systems, including demolition plans, site and utility layouts, cable tray configurations, and extensive input/output mapping for the new switchgear. The design incorporates multiple connectivity points with existing infrastructure, including MidAmerican Energy transformers and connections to existing underground utility corridors. The project is scheduled for completion with a final design submittal dated June 20, 2025, and includes provisions for future microgrid integration and additional electrical infrastructure expansions.
