TUNHEIM CONSTRUCTION, LLC

Tunheim Construction, LLC specializes in heavy civil engineering and commercial building construction, delivering mission-critical infrastructure solutions for federal clients. Their core expertise includes levee restoration, sheet pile removal, roof construction, concrete replacement, and design-build repairs for government facilities. They demonstrate advanced proficiency in earthwork stabilization, structural rehabilitation, and compliance-driven construction methodologies, often working within constrained operational environments such as flood-prone river corridors and active military installations. Their ability to execute complex civil engineering tasks alongside institutional building upgrades highlights a dual-capability model that bridges infrastructure resilience with facility modernization. The contractor maintains a strong, sustained relationship with the Department of Defense, where they perform heavy civil works including flood control infrastructure, military facility repairs, and site-specific engineering interventions. For the General Services Administration, they deliver repair and alteration services across federal properties, including public service buildings and post offices, consistently supporting GSA’s mission to maintain secure, functional federal real estate. Their work reflects a pattern of repeat engagement with both agencies, indicating trusted performance and reliable contract execution. Tunheim’s primary focus lies in NAICS 237990 (Other Heavy and Civil Engineering Construction) and 236220 (Commercial and Institutional Building Construction), positioning them as a niche provider for federally funded infrastructure and facility maintenance. They specialize in projects requiring coordination with environmental regulations, geotechnical constraints, and federal building codes, serving both defense and civilian infrastructure portfolios with precision and regulatory adherence. As a small business entity structured as a 2L with headquarters in Fargo, North Dakota, Tunheim Construction operates regionally but serves nationwide federal missions. While currently holding no formal government certifications, their consistent delivery of complex, federally funded projects underscores a reputation for reliability, technical competence, and on-time execution in high-stakes government environments.
