About this file

Written by GovTribe AI · Dec 28, 2023

This solicitation package outlines requirements for a generator replacement project at Hodges Village Dam in Oxford, Massachusetts. The project includes installing a new 60kW diesel standby generator, coordinating with National Grid to install a new underground utility service, constructing underground duct banks and utility vaults, and upgrading existing electrical systems and equipment to comply with NFPA 70 standards. The solicitation was issued by the U.S. Army Corps of Engineers New England District. The package provides design drawings, specifications and schedules for the electrical work. Responses were due on June 10, 2022. The project aims to replace aging infrastructure and improve reliability of power supply to critical dam operations.
