Addendum%20%233%20North%20Ohio%20Overpass%20Painting

This opportunity is for the complete repainting of the North Ohio Overpass, including bridge fencing, light poles, concrete barriers, and railroad rail, using high‑performance Tnemec coating systems. The scope adds new items for fence pole touch‑up paint removal, longitudinal pipe split repairs, and wire‑mesh tack weld repairs, and requires extensive surface preparation, containment of non‑lead paint residues, and coordination with Union Pacific and K&O railroads. The contractor must provide documentation, conduct a pre‑application meeting, and be prepared for a one‑year post‑completion inspection. • Apply epoxy primer and fluoropolymer topcoat to steel, aluminum, and concrete substrates per SSPC/NACE standards. • Perform high‑pressure water‑blasting, rust removal, and repair of fence defects identified in the fencing analysis. • Manage environmental controls, safety data sheets, and disposal of hazardous paint waste; coordinate rail access and adhere to strict timelines (substantial completion by 15 Oct 2027).
