About the company
Dean Marine And Excavating, Inc., a self-certified small disadvantaged business headquartered in Mt. Clemens, Michigan, performs maintenance dredging, harbor repair, and breakwater restoration across the Great Lakes and coastal waterways as a prime contractor under total small business set-asides. The company operates exclusively as a prime (100% of recent awards) and competes predominantly under small business set-asides, with NAICS 237990 (Other Heavy and Civil Engineering Construction) and PSC codes concentrated in dredging and breakwater construction.
Dean Marine's customer base is singular and concentrated: all 29 awards in the portfolio stem from the Department of the Army and its subordinate U.S. Army Corps of Engineers districts. The Detroit District dominates by potential value ($206.6 million across four awards, including the new $180 million MATOC) while the Army as a parent agency funds ten awards totaling $200.6 million; the Buffalo and Chicago districts account for smaller volumes ($11.9 million and $2.2 million respectively). This concentration reflects Dean Marine's specialization in Great Lakes civil works infrastructure — the company holds a seat on the Great Lakes Dredging Multiple Award Task Order Contract (MATOC), a $180 million five-year indefinite delivery vehicle awarded December 30, 2025, running through December 29, 2030, under which task orders are not to exceed $6 million and are issued firm fixed price.
Recent work exemplifies the portfolio: a $10.2 million definitive contract (April 2026) for repair and rehabilitation of the Lorain West Breakwater Pier in East Aurora, New York, completing September 2028; a $1.78 million contract (April 2026) for FY26 Saginaw River maintenance dredging in Michigan, completing June 2026; an $827 thousand contract (March 2026) for FY24 Alpena Harbor maintenance dredging in Michigan, completing September 2026; and delivery orders under the Great Lakes MATOC including $2.22 million for Keweenaw Waterway and Presque Isle Harbor maintenance dredging (January 2025, completing June 2026) and $2.19 million for Burns Harbor dredging in Indiana (January 2025, completing October 2025). Under prior-generation Great Lakes MATOCs, Dean Marine delivered $3.75 million in FY24 Lorain Harbor dredging (July 2024) and $6.2 million in mobilization and demobilization for Oswego West Arrowhead Breakwater repairs (June 2022).
Activity has accelerated sharply: two awards annually in 2022–2024, seven in 2025, and four year-to-date in 2026. Combined potential value across all awards sits at $448 million, though only $60.2 million (13%) is obligated to date, reflecting the recentness of the new $180 million MATOC award. Recompete exposure in the next twenty-four months is minimal: one award ($827 thousand) faces completion and therefore recompete risk. Dean Marine operates no subcontract relationships in the source data; all work is performed as the prime contractor.
