C.D. Perry has decades of experience delivering marine construction projects in dynamic, over-water and waterfront environments. We maintain a fleet of marine plant — including barges, cranes, spud rigs, and support vessels — and self-perform cofferdams, sheet pile installation, concrete placement over water, and above-water demolition, coordinating closely with dive teams for any subsurface inspection, cutting, or placement work below the waterline. Our marine portfolio includes dam and lock rehabilitation, bridge pier and abutment construction, seawall and bulkhead work, intake and outfall structures, and shoreline stabilization. Working on or near the water introduces variables that onshore work doesn’t — tidal cycles, river currents, restricted access, and regulatory coordination with environmental and navigation agencies. C.D. Perry brings the specialized equipment, experienced crews, and operational planning required to manage those conditions and deliver results
