381 CONSTRUCTORS

381 CONSTRUCTORS specializes in heavy civil engineering construction for critical defense infrastructure, with demonstrated expertise in the design and execution of complex maritime facilities. Their core capabilities center on the construction, renovation, and maintenance of naval dry docks and other mission-critical civil engineering systems, particularly those supporting naval vessel sustainment and repair operations. The company applies advanced earthwork, concrete placement, structural steel fabrication, and marine civil engineering techniques to deliver durable, high-integrity infrastructure under stringent operational constraints. Their technical proficiency includes precision grading, underwater construction, dock sealing systems, and integration of heavy-lift equipment into existing naval yard environments, ensuring minimal disruption to active shipyard operations. What sets them apart is their ability to execute highly specialized, mission-essential projects in secure, high-security naval environments with strict compliance requirements. The contractor has delivered projects exclusively for the Department of Defense, specifically supporting U.S. Navy shipyard operations. Their work focuses on naval infrastructure modernization, particularly dry dock construction and maintenance—critical assets for fleet readiness and vessel overhaul cycles. This singular agency relationship indicates a deep alignment with defense maritime infrastructure needs and suggests a trusted, niche role within the Navy’s shipbuilding and repair ecosystem. Their primary NAICS code, 237990—Other Heavy and Civil Engineering Construction—reflects a focus on large-scale, non-building civil works, including marine structures, dredging, cofferdams, and heavy civil infrastructure not covered under standard building construction categories. This positions them in the defense and maritime infrastructure vertical, serving as a specialized contractor for the U.S. Navy’s shore-based asset sustainment requirements. 381 CONSTRUCTORS is a small business entity headquartered in Omaha, Nebraska, with no federal certifications on record. Their geographic footprint is defined by project-based mobilization to federal defense sites, particularly naval shipyards, rather than permanent regional offices. They operate as a focused, mission-driven contractor serving a highly specialized segment of the national defense infrastructure market.
