A Pittsburgh contractor has been green-lighted for a $31 million project to recoat and rehab the W.D. Mansfield Memorial Bridge over the Monongahela River.
The $30,965,186.27 bid by Joseph B. Fay Co., of Pittsburgh, bested that of eight other contractors.
Scope of Work
The project involves rehabilitating the W.D. Mansfield Memorial Bridge, a 1,931-foot-long cantilevered through-truss bridge built in 1951. The span, also known as the Glassport-Dravosburg Bridge, carries more than 26,000 vehicles daily.
The project includes cleaning and recoating the entire steel superstructure, including top flange and buckle plating. The steel will be abrasive-blast-cleaned to SSPC-SP 10 (Near White) and recoated with an organic zinc-rich primer, an epoxy or urethane intermediate, and a polyurethane finish.
The existing coatings contain lead; containment according to SSPC-Guide 6 and waste disposal according to Guide 7 are required.
Structural steel surfaces will be cleaned and primed with an organic zinc-rich primer. Hand railing, supports, exposed rebar and other miscellaneous steel surfaces will also be cleaned and coated.
