Fiegen Construction

What Fiegen Construction does

Fiegen Construction is a family-owned commercial and industrial general contractor headquartered in Sioux Falls, South Dakota, founded in 1967 by Ron Fiegen as a steel erection and crane rental business and now operating under third-generation leadership as of January 2024 (Lucas Fiegen as President, Mark Stordahl as CFO). The firm serves enterprise and institutional buyers across healthcare, higher education, K-12, financial services, manufacturing, retail, sports and entertainment, religious, and nonprofit verticals in South Dakota, Minnesota, and Iowa, with notable repeat clients including Sanford Health, Sammons Financial, First PREMIER Bank, A-OX Welding, the University of South Dakota, and Mount Marty University. Its differentiated offering is an integrated in-house Design-Build delivery model that combines licensed in-house architecture with construction services under a single contract, paired with self-performed craft capabilities in concrete, precast concrete, steel erection, and carpentry, and a Butler Manufacturing Career Builder partnership for pre-engineered steel buildings.

The company generates revenue through six service lines — General Contracting, Design-Build, Construction Management (with GMP pricing), Pre-Engineered Buildings, Steel & Pre-Cast Erection, and Development — priced on a project-specific basis via competitive bids, RFP responses, and direct proposals with no standardized fee schedule. Go-to-market is sales-led and relationship-based: project acquisition relies on direct field-sales engagement with enterprise and institutional clients, repeat business from a long-tenured client base, and community/industry-association participation (Forward Sioux Falls since 1992, AGC of South Dakota leadership, Build Dakota Scholarship Program). Supporting technology includes REVIT/BIM for design visualization and a Butler partnership for pre-engineered building systems; distribution is direct, not channel-based, and confined to a three-state regional footprint. Backlog is described as strong and diversified through Q3/Q4 2026 with an optimistic 2027 outlook, with FY2023 marking the largest volume of work in the company's history and recent landmark projects including the $55M Sanford Coyote Sports Center, $40M Gage Brothers headquarters, and $15M Mount Marty University Fieldhouse.
