We’ve designed and constructed hundreds of cofferdams, with virtually every geometry and level of complexity imaginable: cofferdams for storage tanks, bridge foundations, building foundations, dams, elevator pits, intake and outlet structures, jacking pits and receiving pits. We perform most cofferdam and excavation support design in-house, which allows us to tailor each design to the project and to our customers’ needs. It also gives us the flexibility to react quickly and effectively if unanticipated conditions are encountered during construction.
