King Co Inc.

King Co Inc. is a for-profit marine construction and dredging company headquartered in Holland, Michigan, that has been registered to receive federal awards since February 2002. The company specializes in hydraulic dredging, sediment and debris removal, and related waterway maintenance services essential to sustaining navigable channels across the Great Lakes region and the Illinois Waterway system. King Co Inc. operates as a self-performing prime contractor that self-executes its dredging work without reliance on subcontractors, and has established itself as a key federal contractor supporting the U.S. Army Corps of Engineers' critical infrastructure maintenance mission.

King Co Inc. has received numerous federal contract awards from the U.S. Army Corps of Engineers for maintenance dredging projects, demonstrating consistent work across multiple Great Lakes harbors and inland waterway systems. The company's contract awards span from 2021 through 2025 and include both definitive contracts and delivery orders, with individual contract values ranging from approximately $358,000 to $2.4 million. Specific projects include maintenance dredging at Grand Haven Harbor, Holland Harbor, Muskegon Harbor, Manistee Harbor, Arcadia Harbor, New Buffalo Harbor, Michigan City Harbor, Kenosha Harbor, Burns Harbor, Green Bay Harbor, and various locations along the Illinois Waterway including Senate Island, Clark Island, and Mackinaw River dredge cuts. The majority of King Co Inc.'s awards have been designated as total small business set-asides, reflecting its status as a qualified small business contractor, though some delivery orders have been issued without set-aside designations. All funding for these contracts has been provided by the U.S. Army Corps of Engineers, either the Detroit District or St. Louis District, supporting the agency's core mission of maintaining proper water depths for commercial and recreational maritime traffic.

King Co Inc. holds three significant Indefinite Delivery Contracts with the U.S. Army Corps of Engineers that form the foundation of its federal contracting relationship. The first is a $25 million single-award Indefinite Delivery Contract for inland waterway hydraulic dredging services, primarily focused on the Illinois Waterway system, with a completion date of December 31, 2025, designated as a total small business set-aside. The second is a $130 million Great Lakes Dredging Multiple Award Task Order Contract (MATOC) awarded in February 2021 with a completion date of February 2, 2025, also designated as a total small business set-aside, which covers dredging, debris removal, and related services across the Great Lakes region. The third is a newly awarded $50 million Multiple Award Task Order Contract (MATOC) from the U.S. Army Corps of Engineers St. Louis District, awarded in September 2025 with a completion date of September 7, 2030, designated as a total small business set-aside that procures comprehensive operations and maintenance dredging services across the St. Louis District Area of Responsibility, encompassing various tributaries, rivers, and reservoirs in Illinois and Missouri. Under these IDVs, King Co Inc. has received numerous task orders ranging from approximately $300,000 to $2.4 million, with individual task order values under the St. Louis District MATOC anticipated to range from $20,000 to $15 million depending on available funding and project requirements.
