We specialize in bridge superstructure elements, like: steel framing, bridge decks and barriers, as well as approach slabs and roadways, curbs, gutters and sidewalks. We have extensive knowledge of transportation department policies, specifications and protocols for highway and bridge construction in New York State and New York City.
Precast and cast in place structures. Cast in place (formed and poured) expertise lies in foundation, retaining structures, and substructure elements such as piers, columns, cap-beams and abutments.
