M C M MARINE, INC.

M C M MARINE, INC. specializes in heavy civil engineering construction with a focused expertise in marine dredging and harbor maintenance operations. The contractor delivers critical infrastructure support through precision dredging, sediment removal, and channel deepening services in coastal and Great Lakes environments. Their technical proficiency includes hydraulic and mechanical dredging systems, environmental compliance during dredge operations, placement limit adjustments, and adaptive scheduling to mitigate weather-related delays. They demonstrate specialized knowledge in navigating sensitive aquatic ecosystems and adhering to U.S. Army Corps of Engineers protocols for dredged material disposal, making them a trusted operator for complex, environmentally regulated waterway projects. The company maintains a consistent relationship with the Department of Defense, providing maintenance dredging services for military-accessible harbors and port facilities across the Upper Midwest. Their work supports naval and coast guard logistics by ensuring navigable depths at strategic locations such as Leland, Portage Lake, Black River, Lac La Belle, Ontonagon, and Cornucopia. These engagements reflect a pattern of recurring, mission-critical support for defense infrastructure resilience, often involving modifications to address evolving operational or environmental constraints. Their primary industry focus is under NAICS 237990, which encompasses other heavy and civil engineering construction not elsewhere classified—specifically, non-structural marine civil works. This positions them as a niche provider in federal waterway infrastructure, serving defense and potentially other federal agencies requiring specialized dredging capabilities in remote or ecologically sensitive regions. They operate with a high degree of technical specificity in littoral zone engineering and harbor maintenance. M C M MARINE, INC. is a small business structured as a 2L entity, headquartered in Sault Ste. Marie, Michigan. While no federal certifications are listed, their geographic positioning in the Great Lakes region provides strategic advantage for responding to federal maintenance needs in the Upper Midwest. Their market presence is defined by operational agility, regulatory compliance, and deep familiarity with regional hydrographic conditions.
