The Dutra Group

The Dutra Group, headquartered in San Rafael, California, and doing business as Dutra Dredging, is a leading marine construction and dredging company specializing in critical maritime infrastructure services for federal agencies. As a for-profit corporate entity and parent company with subsidiaries including San Rafael Rock Quarry, Inc., The Dutra Group has established itself as a prime federal contractor with extensive experience executing complex dredging, waterfront construction, and coastal engineering projects across U.S. ports, harbors, and waterways. The company brings specialized expertise in hopper dredging, mechanical and cutterhead dredging applications, material placement and disposal operations, shore protection, and erosion control projects that support the federal government's mission to maintain navigable waterways and critical maritime infrastructure.

The Dutra Group has been awarded numerous prime federal contracts by the U.S. Army Corps of Engineers and Department of the Navy totaling hundreds of millions of dollars in contract value over the past several years. Recent definitive contracts include a $27.2 million firm fixed-price contract for hopper dredging services in the Corpus Christi Entrance Channel, Texas (awarded September 2025); a $9.3 million contract for Petaluma River channel maintenance dredging in California (August 2025); an $8.07 million contract for the Military Ocean Terminal Concord Berms Construction and Dredging Project in California (August 2025); and a $4.3 million contract for Sacramento Deep Water Ship Channel annual maintenance dredging (June 2025).

These contracts have been awarded on an unrestricted, full and open competition basis without small business set-asides, reflecting the company's competitive standing among qualified contractors. The work involves removal of shoaled material to authorized depths, environmental monitoring and species protection, turbidity monitoring, sea turtle and bird monitoring, material placement at upland or ocean disposal sites, and compliance with stringent environmental and operational constraints. The Dutra Group engages multiple specialized subcontractors to support project execution, including firms providing towing and marine support services, environmental monitoring, surveying and geospatial data collection, equipment rental, fuel and supply services, and specialized environmental remediation services. Funding for these awards has been provided by various U.S. Army Corps of Engineers districts including San Francisco, Jacksonville, Wilmington, Portland, Baltimore, New York, and Sacramento, as well as the Department of the Navy.

The Dutra Group currently holds two significant multiple-award Indefinite Delivery Contracts (IDCs) with the Department of the Navy. The first is a $995 million IDC awarded by Naval Facilities Engineering Command (NAVFAC) in June 2022 for design-build and design-bid-build waterfront construction services at various locations in Hawaii and Wake Island, with a performance period through June 2027. Under this contract vehicle, The Dutra Group provides services including new construction, repairs, and maintenance of piers, wharves, waterfront facilities, bridges, and utilities supporting the Navy's critical maritime infrastructure requirements in the Pacific region, with individual task order values ranging from $5,000 minimum guarantees up to $200 million. The second is a $326 million multiple-award IDC awarded by NAVFAC in February 2021 for new construction, repair, alteration, and renovation of marine waterfront facilities within the NAVFAC Northwest area of responsibility, with a completion date of February 2026. Under this contract, The Dutra Group provides dredging, waterfront construction, and coastal engineering services across the Pacific Northwest. Both IDCs carry no small business set-aside designations, indicating the company secured these awards through full and open competition. Task orders issued against these contracts have included a $521,000 firm fixed-price delivery order for concrete wall, floor, and pumpwell repairs at Naval Base Bremerton, Washington, and various minimum guarantee orders for construction services. Additionally, The Dutra Group has access to the SAD Dredging and Shore Protection 2019 multiple-award IDIQ contract vehicle managed by the U.S. Army Corps of Engineers' South Atlantic Division, through which the company has been awarded several delivery orders for maintenance dredging and shore protection projects in Florida, including work at Canaveral Harbor and Brevard County.
