George St Bridge Replacement

The City of Keene, New Hampshire is seeking qualified contractors for the George Street Bridge Replacement Project #40653, a federally funded infrastructure initiative administered through the New Hampshire Department of Transportation (NHDOT). The procurement is a comprehensive bridge replacement project targeting the existing 13-foot single-span bridge over Beaver Brook, with an anticipated construction start in Spring 2026. Contractors must submit bid proposals by November 6, 2025, with a mandatory pre-bid meeting scheduled for October 16, 2025, at 350 Marlboro Street in Keene. The project requires full compliance with federal funding and NHDOT Local Public Agency (LPA) requirements, involving extensive infrastructure work including bridge replacement, utility reconstruction, roadway approaches, and drainage improvements. Bidders must provide detailed documentation demonstrating company qualifications, relevant experience, equipment capabilities, and financial stability, with a required 5% bid bond of the total bid amount. The contract includes 300 calendar days for substantial completion and 330 calendar days for total contract completion, with liquidated damages of $1,280 per day for delays beyond established completion dates.

The project has specific Disadvantaged Business Enterprise (DBE) guidelines and requires adherence to federal aid construction contract provisions, including Davis-Bacon wage rates and Build America Buy America requirements. Potential contractors must demonstrate expertise in managing complex infrastructure projects, particularly those involving environmental considerations such as PCE-impacted soil and groundwater management, invasive species control, and wetlands preservation. While no specific incumbent vendors are mentioned, the project involves geotechnical complexities, including potential foundation approaches such as precast box culvert, spread footing foundations, and micropile options, as detailed in the geotechnical engineering report. The site consists of granular fills, native sand and gravel, and glacial till overlying bedrock at depths of approximately 20-21 feet, with AASHTO Site Class D seismic classification. Although a precise budget is not specified, the federal funding and comprehensive scope suggest a significant infrastructure investment, likely in the multi-million dollar range, with rigorous technical and environmental compliance requirements.
