Scope of Work
The project includes coating exposed surfaces of all 804 steel railing posts and associated connection plates of 12 cantilevered deck truss spans. The limits of coating application include all internal surfaces of box-shaped members accessed through manholes, up to and including the exposed sides of the seal plates.
The project also includes replacing the bottom rail on both sides of the entire bridge, excluding the suspension spans and the through truss cantilever spans.
The existing steel will be abrasive blast cleaned to a Near-White finish (SSPC-SP 10), spot power-tool-cleaned to SP 11, and coated with the Maryland State Highway Administration (MDSHA) Paint System C, which consists of an organic zinc-rich primer, an epoxy intermediate, and a polyurethane finish.
Containment is required to capture the existing lead-based coatings. A paint system warranty is also required.
The project includes coating the new steel railing with the MDSHA System B, which consists of an inorganic zinc-rich primer, an epoxy intermediate, and a polyurethane finish. The project also includes performing miscellaneous structural repairs.
