About the company
Morrish-Wallace Construction, Inc., doing business as Ryba Marine Construction CO., is an SBA-certified HUBZone small disadvantaged business based in Cheboygan, Michigan, that delivers dredging, harbor maintenance, and marine construction services to federal agencies as a prime contractor (100% of recent awards). The vendor operates exclusively under its own prime contracts and holds no subcontract footprint; its customer concentration sits heavily with the Army Corps of Engineers across the Great Lakes region.
Ryba Marine Construction's federal footprint centers on three core capabilities: maintenance dredging across the Great Lakes (mechanical dredging, dredged material disposal, confined disposal facility management), harbor and breakwater repairs (armor stone overlays, pier rehabilitation, perimeter dike raising), and ancillary marine construction (mobilization/demobilization of equipment, environmental compliance, surveys). Representative definitive contracts awarded in 2025–2026 include a $3.49 million Lake St. Clair and St. Clair River maintenance dredging contract (Army Corps of Engineers, awarded August 2025, total small business set-aside), a $2.3 million West Dickinson Offloading Platform construction contract (Army Corps of Engineers, awarded March 2026, total small business set-aside), a $5.8 million CDF #4 Perimeter Dike Raising project in Buffalo Harbor (Army Corps of Engineers, awarded March 2025, no set-aside), and a $4.2 million delivery order for Bird Island Pier repairs in Buffalo (Army Corps of Engineers, awarded March 2026, no set-aside). Smaller task orders flow under the Great Lakes Dredging Multiple Award Task Order Contract and parallel vehicles at routine completion-date intervals.
Customer concentration is extreme: the Department of the Army Corps of Engineers accounts for 83% of recent awards by count and 98% of combined potential value. Within that agency, two district offices dominate: the Corps' Engineering District Detroit (44 awards, $261.6 million combined potential value) and Engineering District Buffalo (62 awards, $150.7 million combined potential value). A secondary customer, the Environmental Protection Agency Region 5, carries $181.5 million in potential value across only four awards (likely large site remediation or dike projects). The Department of Homeland Security U.S. Coast Guard, with 33 awards, contributes only $1.8 million and appears to reflect minor dock-space or vessel-support calls. The vendor has worked with 15 distinct federal agencies total, but the top five account for 98% of combined potential value.
Ryba Marine Construction holds four active indefinite delivery vehicles with the Army Corps of Engineers. The Great Lakes Dredging Multiple Award Task Order Contract (MATOC), a $180 million total small business set-aside awarded December 2025 through December 2030, anchors the portfolio and has generated 23 task orders worth $44.3 million to date. The Design-Bid-Build Marine Construction Lakes Districts MATOC, a $260 million multiple-award vehicle awarded February 2023 through January 2028, has produced 5 task orders worth $18.2 million. A $25 million single-award Green Bay Harbor Dredging contract (total small business set-aside, February 2026 through February 2031) is newly established with no task order activity visible in the source. A $16 million single-award Toledo Harbor Indefinite Delivery Contract (May 2024 through May 2026, no set-aside) serves a two-year ordering period for approximately one million cubic yards of dredging across fiscal years 2024–2025. Older vehicles including the $130 million USACE Detroit Great Lakes Dredging MATOC 2016–2018 and various district-level IDCs continue to generate minimal residual activity. The Fish and Wildlife Service Region 3 awarded a single-award Blanket Purchase Agreement (March 2026, $200,000 ceiling) for dock space and vessel support at the Alpena Fishery Habitat Restoration Site in Michigan.
Set-aside posture is characteristic across the prime footprint: of 282 total awards in the vendor's portfolio, 194 are categorized under NAICS 237990 (Other Heavy and Civil Engineering Construction), and the majority carry Total Small Business or HUBZone set-aside designations, though some delivery orders under larger MATOCs are issued without set-aside. The vendor competes predominantly under set-asides, particularly total small business and HUBZone, with occasional full-and-open task orders drawn from multiple-award vehicles where set-aside status is determined at the task-order level rather than the IDV level.
Activity has remained flat to modestly declining: nine awards in 2022, ten in 2023, nine in 2024, ten in 2025, and eight through April 2026. The recompete cliff is minimal—only ten awards with ultimate completion dates in the next twenty-four months carry combined potential value of $19.5 million, and most represent routine renewal or extension of dredging task orders under existing MATOCs. Combined obligated dollars across all awards total $383.3 million against a combined potential value of $1.3 billion, indicating 29% drawdown across the portfolio, consistent with multi-year contract structures and long seasonal performance windows typical of Great Lakes dredging and marine construction work.
