Ryba Marine Construction Co.

What Ryba Marine Construction Co. does

Ryba Marine Construction Co. is a privately held, employee-owned heavy civil marine construction firm headquartered in Cheboygan, Michigan on Lake Huron, operating under the legal name Morrish Wallace Construction, Inc. Founded in 1983 and incorporated in 1987, the company is a HUBZone Certified Small Business that has grown from its Great Lakes origins to provide marine construction services throughout the United States. Its core service portfolio spans environmental capping and remediation, mechanical and hydraulic dredging, heavy civil construction (including dams, ports, harbors, navigational structures, and pile driving), commercial dock and marina construction, marine pipeline and cable crossing installation, breakwaters and shore protection, salvage, towing and tug assistance, and emergency response including spill containment. Customers are primarily federal agencies such as the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, and U.S. Coast Guard, complemented by state agencies, municipalities, utilities, and shipping firms, with a smaller secondary residential waterfront customer base served through an Inland Waterways Services division.

The company differentiates on GPS/RTK-integrated dredging and surveying systems, ACSM certified hydrographers, certified commercial divers, U.S. Coast Guard certified equipment and operators, and a self-performed delivery model that reduces reliance on subcontractors. Notable technical capabilities include single-beam and multi-beam acoustic sounding, side-scan imagery, mobile and stationary Lidar, acoustic backscatter, and sediment sampling for environmental remediation projects. Documented project execution includes 147,500 cubic yards of contaminated sediment removal and 9 acres of residual sand cover placement on the Sheboygan River, 167,000 cubic yards of PAH and PCB contaminated sediment dredging on the Kinnickinnic River, and the U.S. Army Corps of Engineers Civil Works Construction Contractor of the Year award for pier repairs completed six months ahead of schedule.

Revenue is generated through fixed-price contracts, time-and-materials arrangements, and government contracts on heavy civil marine construction projects, supplemented by used marine construction equipment sales (diesel hammers, leads, grizzly power units) and a Magnum Boat Lift dealership serving residential and commercial customers in inland waterways. The company secured a joint venture with Terra Contracting, LLC carrying a maximum $150 million contract value with the EPA Great Lakes National Program Office. The company transitioned to employee ownership via an ESOP in 2019 under President Zachary W. Morrish, who succeeded founder Tom Morrish in 2011, preserving family leadership while broadening ownership across the workforce.
