CASHMAN DREDGING & MARINE CONTRACTING CO LLC

CASHMAN DREDGING & MARINE CONTRACTING CO LLC specializes in maintenance dredging and sediment management for federal navigation channels, harbors, and waterways. The contractor delivers precision dredging operations using advanced hydraulic and mechanical equipment to remove accumulated sediments, restore channel depths, and ensure safe maritime transit for military and commercial vessels. Their technical expertise includes dredge material transport, placement, and environmental compliance in sensitive coastal and estuarine environments, with demonstrated experience in complex federal navigation projects along the Atlantic seaboard. Key differentiators include operational agility in constrained harbor settings, adherence to U.S. Army Corps of Engineers standards, and proven ability to execute time-sensitive maintenance cycles under demanding maritime conditions. The company maintains a consistent and primary relationship with the Department of Defense, supporting critical infrastructure at U.S. Naval Stations and military port facilities. Their work directly enables fleet readiness by maintaining federal navigation projects such as those in Mayport, Jacksonville, Bath, Baltimore, and Portsmouth Harbor, ensuring unimpeded access for naval assets. These engagements reflect a long-standing partnership focused on mission-critical waterway maintenance rather than new construction. The contractor’s primary NAICS code, 237990 — Other Heavy and Civil Engineering Construction — reflects their focus on large-scale marine civil works, particularly dredging and sediment handling within federally authorized navigation systems. They operate within a niche vertical centered on defense and maritime infrastructure resilience, positioning them as a specialized provider for federal agencies managing coastal and inland waterway assets. CASHMAN DREDGING & MARINE CONTRACTING CO LLC is a small business headquartered in Quincy, Massachusetts, with no federal certifications on record. Their operational footprint is concentrated along the Northeastern U.S. coastline, where they deliver high-precision marine construction services tailored to the unique demands of military and civilian port authorities.
