About this file

Written by GovTribe AI · Dec 28, 2023

This solicitation seeks proposals for a bridge replacement project located in Cassia County, Idaho. The project involves replacing an existing burnt bridge over Harrington Fork with a new 40-foot long prefabricated steel bridge supported by glued laminated timber abutments. Administrative work is estimated to begin in June 2023 with ground work starting in September and concluding in November 2023. The actual bridge installation will occur in Spring/Summer 2024. The estimated value of construction is between $250,000 to $500,000. This opportunity is set aside for small businesses in NAICS code 237310 with a size standard of $45 million. A site visit is scheduled for June 6, 2023 at 11:00 AM local time at the project location provided. Proposals are due by the closing date of the solicitation.
