Security & Emergency Response
The Dutra Group is a trusted provider of rapid-response marine construction and dredging services for critical infrastructure emergencies. When unexpected events threaten the stability of levees, bridges, ports, or other waterfront assets, Dutra has the expertise, equipment, and personnel to mobilize quickly and restore function. Our team is experienced in working under pressure, often deploying within hours to stabilize structures and prevent further damage.
We routinely partner with public agencies, including the U.S. Army Corps of Engineers, Caltrans, and local reclamation districts, to provide emergency repair and recovery services following storms, vessel impacts, levee failures, and other urgent incidents. From demolition and debris removal to the construction of protective systems like fender walls and revetments, we deliver fast, effective solutions that safeguard public safety and infrastructure.
In addition to physical repairs, Dutra supports maritime security efforts through infrastructure hardening and strategic upgrades. This includes reinforcing access points, upgrading mooring systems, and enhancing shoreline protection around critical facilities. Our ability to operate in sensitive environments and deliver turnkey solutions makes us a key resource in times of both crisis and prevention.
