THE DUTRA GROUP

The Dutra Group specializes in heavy civil engineering construction with a focused expertise in harbor and waterway maintenance dredging, channel deepening, and coastal infrastructure projects. Their core capabilities include the mobilization and demobilization of large-scale dredging fleets, precision sediment removal in sensitive marine environments, and the execution of complex navigation channel maintenance under strict environmental and safety protocols. The company demonstrates deep technical proficiency in hydraulic and mechanical dredging operations, sediment management, and hydrographic survey integration to support U.S. Army Corps of Engineers and DoD maritime infrastructure programs. Their work consistently targets critical defense ports and strategic waterways, requiring advanced coordination of heavy equipment, real-time bathymetric monitoring, and compliance with federal ecological regulations. The contractor maintains a strong and consistent relationship with the Department of Defense, delivering mission-critical dredging services for naval bases, harbor access channels, and coastal defense infrastructure across Florida, California, Oregon, Washington, and Texas. Their projects support operational readiness by ensuring deep-draft vessel access to military ports and maintaining navigational safety in high-traffic maritime zones. The primary NAICS code 237990 reflects their specialization in other heavy and civil engineering construction, specifically in marine and inland waterway infrastructure. This positions them as a niche provider in the defense and federal civil works sectors, where expertise in large-scale aquatic earthmoving and channel stabilization is in high demand. The Dutra Group is structured as a 2L entity with its headquarters in San Rafael, California. While no federal certifications are listed, their consistent performance on high-complexity DoD projects underscores a proven track record in meeting stringent federal construction standards. Their geographic presence is anchored on the West Coast, with operational reach extending to major defense harbors nationwide.
