In 1967, Ron Fiegen started with a steel erection and crane rental business in Sioux Falls, SD. Fiegen Construction Co. quickly evolved into a general contracting firm specializing in commercial and industrial construction. In the early 1990s, Ron’s sons, Jeff and Rusty, combined construction and architecture into in-house design/build delivery. In-house DB streamlined the process, creating lower costs, higher quality and schedule control with unparalleled collaboration with a team of professionals.
In 2016, Mark Stordahl (CFO) and Jeff’s son Lucas Fiegen, AIA, joined the Leadership Team of the company. As a 50+ year general contractor, we continue to employ a skilled workforce and self-perform concrete, precast concrete, steel erection and all facets of rough and finish carpentry. Additionally, our outstanding relationships with premier industry subcontractors and suppliers allow us to set the pace of schedules, push innovation and maintain the highest quality control throughout the life of any size project.
Our operating principles have always been:
With almost four decades of experience, Jeff has excellent long-standing relationships with design professionals, subs, suppliers and building officials. A leader in community organizations and civic events, his extensive construction experience is the foundation for managing the region’s fastest-growing General Contracting firm.
With over 35 years of local experience, Rusty has a broad understanding of successfully administering all facets involved in the construction process from inception to completion. His first-hand knowledge of construction techniques and methods brings impactful experience to his management responsibilities.
A graduate of the University of Nebraska-Lincoln, Lucas received his Master’s in Architecture while gaining valuable experience working summers for Fiegen Construction. He is a licensed architect and will continue to serve as lead to Fiegen Construction's In-House Design Build/Architectural Department.
Mark joined Fiegen Construction in 2003 with a background in finance and administration experience. He is responsible for all financial aspects of the company, including accounting, insurances, job costing, internal controls, audits, contracts, pro forma financials and Design-Build-Lease development.
