What Willadsen Lund Engineering does
Willadsen Lund Engineering Corporation is a privately held civil engineering and land surveying firm founded in 1995 and headquartered at 902 S. Cleveland Avenue in Sioux Falls, South Dakota. The firm is licensed to practice professional engineering in South Dakota, Nebraska, and Iowa, and serves private land developers, municipal governments, and institutional clients across the Sioux Falls region and broader upper Midwest. Its core offering is full-lifecycle civil engineering site design, supported by sixteen service lines spanning stormwater modeling, floodplain analysis and FEMA LOMR/LOMA documentation, urban roadway design, erosion control (BMP), construction administration, topographic surveys, construction staking, earthwork volumetric analysis, project cost estimating, and professional litigation support. The firm holds no external investment, has no parent company, and operates with a small team of professional engineers, designers, and engineering technicians.
The business model is project-based, fee-for-service professional services delivered through direct, relationship-driven engagement with enterprise and mid-market clients. Go-to-market is sales-led: clients are acquired through professional reputation, repeat relationships, and referrals from the regional development and construction community, with the company website serving as a portfolio and contact channel. Pricing is custom-quoted per project depending on scope and complexity, with multi-year contract cadences for ongoing engagements. Revenue streams are concentrated in civil engineering services for residential subdivisions, commercial and retail developments, office parks, industrial sites, schools, and municipal infrastructure. Leadership is founder-anchored: Eric P. Willadsen, P.E. (B.S. Civil Engineering, South Dakota State University, 1986) serves as President and is responsible for day-to-day operations, supported by long-tenured Project Engineer Robert Roth (joined 2000) and Senior Engineering Technician Troy Luettel (~14 years). The firm's underlying technology stack is conventional for the sector — CADD systems for design and drafting, integrated surveying technology, and domain-specific stormwater and floodplain modeling — with no disclosed AI/ML, API, or software-product components.
