A prefabricated pier system provides prefabricated foundation and cap components for assembly with a series of steel H section columns to facilitate construction of bridges, overpasses, and similar structures. Each foundation component comprises a prefabricated column base sleeve, with sleeve pairs welded to a horizontal support to form pier foundation assemblies. These prefabricated assemblies are then welded to leveling beam pairs at the construction site and anchored in a concrete footing to form the foundation for each pier assembly. Each pier cap comprises a series of prefabricated sections, each having a single depending column end pocket for accepting a pair of column members therein. The sections are assembled to form the completed pier cap box, installed atop the column members, and used as a permanent form for casting the concrete pier cap. The present system may be used with either conventional single girder span construction or with built up girders.
