About this file
This document appears to be construction drawings and specifications for an electrical upgrade project at the Bradford Island Service Building near the Bonneville Lock and Dam. The project objectives are to replace the existing 480V switchboard and transformers, relocate the new transformers and disconnect switches outside the building, house the new 480V switchgear in the existing electrical room, and provide cooling and other life safety upgrades for the room. The drawings provide details on the required new duct bank, conduits, and cable installation to support the electrical upgrades. This project is associated with the federal contract opportunity W9127N24R0012 for the "BRADFORD ISLAND SERVICE BUILDING PRQ SWITCHGEAR UPGRADE" being solicited by the U.S. Army Corps of Engineers Portland District.
