Precast is utilized to construct both the superstructure and substructures of all types of bridges. Superstructures include: flat slabs, adjacent box beams, pretensioned beams, spliced and curved girders. Whereas substructures include: precast end bents, piles and pile bent caps, water line pile caps, and precast columns.
