Great Lakes Dredging Multiple Award Task Order Contract

The Department of the Army Corps of Engineers awarded the Great Lakes Dredging Multiple Award Task Order Contract on February 3, 2021, as a multiple-award IDIQ for maintenance dredging and associated construction services within the Buffalo, Chicago, and Detroit Districts. The vehicle's ordering period closed on February 2, 2025, after nearly four years of active task-order issuance. With 94 task orders awarded totaling $127.2 million in combined potential value, the vehicle has obligated $120.7 million (95% of potential value), indicating near-full utilization before ordering closure.

Task-order activity remained steady through the vehicle's life, with annual ordering ranging from 19 orders in 2021 to 25 in 2022 and declining to 8 orders in 2025 following the February 2025 cutoff date. Recent orders show the vehicle continues to fund harbor maintenance dredging at specific Great Lakes locations—Burns Harbor, Waukegan, Green Bay, and Lorain among them—with firm-fixed-price task-order values typically ranging from under $200,000 to approximately $4.3 million. The vehicle's $130 million shared ceiling accommodated growth from the originating solicitation's $100 million estimate.

Eight prime contractors hold awards under the vehicle. Morrish-Wallace Construction, Inc. and King Co Inc. dominate by combined potential value, with Morrish-Wallace holding 23 orders worth $44.3 million and King Co holding 27 orders worth $25.9 million. Together these two firms capture roughly 55% of combined potential value. Roen Salvage CO., Dean Marine And Excavating, Inc., and Great Lakes Dock And Materials, L.L.C. represent the next tier; smaller firms complete the awardee pool with limited individual order counts. The Department of the Army Corps of Engineers funds approximately 79% of combined potential value across its multiple organizational units, with the remaining orders split among other Army entities and specialized civil-works funding.

The set-aside mix favors open competition: 63% of awards carried no set-aside, while 36% were total small-business awards and 1% was partial small business. Task orders issued in early 2025 before the cutoff show continued small-business emphasis, with total small-business designations on five of the most recent eight awards. Performance spans multiple Great Lakes harbors and waterway segments within the three USACE districts, with no single location capturing disproportionate share of activity. All awarded task orders use firm-fixed-price contracting and include variation-in-estimated-quantity provisions typical of dredging work, where actual volumes often differ from initial estimates.
