The Maine Department of Transportation is soliciting bids for the Specialist Wade A Slack Memorial Bridge Girder Repair project in Waterville, Kennebec County. This federal aid project involves repairing a north fascia girder in Span No. 2 of the bridge located on Interstate 95 Southbound over Main Street/Route 104. The repairs are necessitated by a bridge strike from a trailer carrying a large forklift, which caused a 2-3 inch outward sweep, weld tearing, and a significant crack through the flange and web of the westerly exterior girder. The scope of work includes heat straightening of the damaged structural steel, the installation of temporary structural supports to eliminate flexural effects at the vertical crack, and field painting using a zinc-rich coating system. The contract will be awarded to the lowest responsive bidder who has completed or successfully completes a bridge or project-specific prequalification. Bids are due by 11:00 AM on October 14, 2026, and must include a 5% bid guarantee. The successful contractor must provide performance and payment bonds totaling 100% of the contract price and is required to complete all work by June 18, 2027. Key technical requirements include adherence to NSBA G2.2 and AASHTO LRFD standards, 100% visual and magnetic particle testing on connection plate welds per AWS D1.5, and strict compliance with OSHA lead abatement and hazardous material regulations. The project also includes extensive pavement marking and traffic control maintenance.
