About this file
This document appears to be a solicitation for the BONNEVILLE LOCK AND DAM POWERHOUSE 1 METERING ENHANCEMENT project. The scope of work includes the contractor furnishing all supervision, engineering, labor, materials, and equipment to install new current transformers (CTs) and replace potential transformers (PTs) at the Bonneville Dam in Multnomah County, Oregon. The government will provide the metering-grade CTs and PTs as government-furnished equipment. The contractor's responsibilities include fabricating and installing the new CT supporting structures, installing the CTs, replacing the PTs, and conducting field acceptance testing. The estimated magnitude of construction is $1,000,000 to $5,000,000. This is a full and open competition solicitation under NAICS code 238210 with a size standard of $19 million. The Product Service Code is Z1KA - Maintenance of Dams.
