About the company
The Dutra Group, doing business as Dutra Dredging, is a for-profit marine construction and dredging company headquartered in San Rafael, California, that delivers hopper dredging, mechanical and cutterhead dredging, channel maintenance, harbor deepening, shore protection, and erosion control services to federal agencies as a prime contractor (99% of recent awards) competing on a full-and-open basis with no set-aside designations. The company operates across 17 federal customer agencies with a $4.72 billion combined potential value in recent contracts and an obligated commitment of $1.07 billion (23% of combined potential value).
The vendor's customer concentration is heavily weighted toward maritime infrastructure maintenance and navigation projects within the Army Corps of Engineers and Department of the Navy. The Department of the Army Corps of Engineers accounts for 23 awards valued at $408.7 million combined potential, supplemented by substantial activity within specialized engineering districts: Jacksonville (11 awards, $643.3 million), Mobile (12 awards, $79 million), San Francisco (9 awards, $112.6 million), and New Orleans (10 awards, $74.1 million). The Department of the Navy Naval Facilities Engineering Command dominates the potential-value ranking with 6 awards carrying $3.07 billion combined potential value, anchored by the Design-Build and Design-Bid-Build Waterfront Multiple Award Construction Contract for Hawaii and Wake Island waterfront services (multiple award indefinite delivery contract running through June 2027 with a $1.99 billion ceiling). Recent concrete examples of prime work include a $71.17 million firm fixed-price definitive contract from the Army Corps of Engineers (Sacramento District) for Sacramento River erosion control and mitigation work (ultimate completion February 2028), a $75.4 million Mobile Harbor Deepening & Widening Phase 6 contract, a $67.87 million Atlantic Ocean Channel Phase 1 deepening project in Norfolk, and a $43.021 million delivery order for Shore Protection Project renourishment in Brevard County, Florida under the SAD Dredging and Shore Protection 2019 IDIQ (which carries 5 task orders totaling $121.2 million combined potential value).
Activity has remained relatively flat over the past five years (5 awards annually in 2022 and 2025, declining to 4 awards in 2026 year-to-date), with recompete exposure of $81.4 million in combined potential value from three awards reaching ultimate completion within the next twenty-four months. The company subcontracts minimally (1% of awards by count), with recent sub engagement routed through Manson Construction Co on a Norfolk Harbor Atlantic Ocean Channel dredging Phase 2 project. Across its prime footprint, The Dutra Group engages a consistent subcontracting ecosystem including Ryzhka International LLC (SDVOSB and HUBZone certified) for tug fuel and lubricant supply, Yaypen Supply LLC (WOSB and EDWOSB) for marine fuels and waste removal, Woolpert Inc. for dredging quality monitoring and surveying, Dann Ocean Towing Inc. for tug and tow services, and specialized vendors for environmental monitoring, equipment rental, and marine logistics. The vendor operates through four subsidiaries: San Rafael Rock Quarry Inc., Hanford Applied Restoration & Conservation, Dutra Construction Co. Inc., and Dutra Dredging Company. NAICS concentration is uniform (Other Heavy and Civil Engineering Construction across 91 awards), with PSC activity split among Construction of Dredging Facilities (30 awards), Construction of Canals (17 awards), Maintenance of Dredging Facilities (15 awards), and subordinate categories.
