NORTHERN INTERSTATE CONSTRUCTION, INC.

Northern Interstate Construction, Inc. specializes in heavy civil engineering construction and the rental of specialized earthmoving equipment for federal infrastructure projects. Their core capabilities include the design and execution of large-scale waterway and maritime infrastructure, such as ship canal maintenance and dredging operations, alongside the mobilization and deployment of heavy excavation machinery for confined or environmentally sensitive sites. The contractor demonstrates technical proficiency in marine construction, pier and bulkhead remediation, and the safe removal of submerged or embedded equipment, requiring precision engineering and adherence to U.S. Army Corps of Engineers standards. Their ability to integrate equipment leasing with on-site civil works creates a unique operational model, enabling rapid response and resource optimization without reliance on third-party vendors. The company maintains a consistent relationship with the Department of Defense, delivering mission-critical infrastructure support for naval and coastal defense assets. Their work includes the repair and modernization of navigational channels, harbor structures, and military port facilities, often under stringent operational timelines and environmental compliance protocols. This recurring engagement suggests a trusted partnership in sustaining DoD’s maritime readiness infrastructure. Northern Interstate Construction primarily operates under NAICS 237990, focusing on other heavy and civil engineering construction—specifically marine, dredging, and coastal engineering projects—and 532412, which reflects their strategic use of proprietary excavation and material handling equipment as both a service and an enabler of civil works. This dual focus positions them as a niche provider in defense-aligned maritime infrastructure, blending equipment mastery with hands-on construction execution. As a small business structured as a 2L entity based in South Range, Wisconsin, the company operates with a lean, regional footprint but serves national defense infrastructure needs. While they hold no formal government certifications, their demonstrated performance on DoD projects underscores a proven ability to meet federal construction standards and logistical demands in challenging environments.
