L S MARINE INC

L S MARINE INC specializes in heavy civil engineering construction with a focused expertise in dredging operations and maritime infrastructure maintenance. The company delivers precision dredging services for military and defense-related waterways, including harbor deepening, channel clearance, and sediment removal from sensitive coastal and inland water systems. Their technical capabilities encompass mobilization of specialized dredging equipment, hydraulic and mechanical dredge operations, environmental compliance during excavation, and site restoration following project completion. Key differentiators include rapid mobilization of plant assets, experience with DoD-mandated environmental protocols, and the ability to execute complex dredging missions in constrained or high-traffic maritime zones, such as small boat harbors and strategic waterways. The contractor maintains a consistent and exclusive relationship with the Department of Defense, delivering mission-critical dredging services across multiple naval and military installations. Their work supports naval readiness by ensuring safe navigation, port accessibility, and infrastructure resilience in defense-critical waterways. All awarded projects are directly tied to DoD operational requirements, indicating a trusted, recurring partnership built on reliability and technical precision in austere environments. L S MARINE INC operates primarily under NAICS 237990, which encompasses other heavy and civil engineering construction not elsewhere classified—specifically, large-scale aquatic infrastructure projects requiring heavy machinery, marine logistics, and environmental stewardship. The company’s market positioning is narrowly focused on defense-related dredging and maritime construction, distinguishing itself as a niche provider with deep domain knowledge in military waterway maintenance. As a small business structured as a 2L entity based in Inver Grove Heights, Minnesota, L S MARINE INC maintains a lean, specialized operational footprint. While no federal certifications are listed, the company’s consistent performance on DoD contracts demonstrates proven compliance with federal construction standards and environmental regulations. Their geographic presence is defined by project-based deployment rather than regional office networks, positioning them as a responsive, mission-ready contractor for time-sensitive defense infrastructure needs.
