About this file

Written by GovTribe AI · Dec 28, 2023

This set of construction drawings and related documents outline requirements for replacing electrical conduits and wiring at the North Springfield Lake Dam in North Springfield, Vermont under solicitation number W912WJ20B0005 from the U.S. Army Corps of Engineers, New England District. The scope of work involves demolishing existing conduits and installing new PVC-coated galvanized steel conduits for power, communications, instrumentation and strong motion sensors. Additional requirements include installing new telephone cable and fiber optic cable from the project office to the gatehouse, upgrading instrumentation cables and reconnecting to the existing system, and providing a new service entrance disconnect. The contractor must coordinate work with the utility providers and ensure emergency power is maintained. The drawings depict existing conditions, demolition plans, new work plans including conduit routing and details, riser diagrams and general notes.
