Written by GovTribe AI · Dec 28, 2023

This document provides details on a federal contract solicitation for GSU transformer installation work at Fort Peck Powerhouse in Montana. The Army Corps of Engineers Engineering District Omaha is seeking bids to remove existing GSU transformer banks and oilostatic feeders, move two government furnished equipment transformers to new locations, provide new feeders and connections for the transformers, and install new group-operated disconnect and protection/control/annunciation wiring to make the equipment fully operational. A virtual site visit was scheduled for July 21, 2020 and the solicitation will close on August 11, 2020. The estimated construction cost is between $5 million and $10 million. The primary NAICS code is 237130 for power and communication line structure construction with a $36.5 million size standard for small businesses. Interested parties can obtain the solicitation documents through the beta SAM website by searching for the solicitation number.
