Our History

Founded in 1967, Fiegen Construction Co. is a family owned and operated commercial design and construction firm with an excellent reputation for quality, on time performance and innovation.

As a young man, founder Ron Fiegen left the Sioux Falls area for a career as a journeyman ironworker in New York, NY. He advanced quickly to supervisory positions in steel and precast concrete erection and heavy rigger operations, working on projects throughout the United States. He brought his expertise back to his home state in 1967 and started his own steel erection business. The company quickly evolved into a general contracting firm specializing in commercial and industrial construction. In the early 1990’s, Fiegen Construction Co. combined architecture and construction, offering a construction delivery method called Design/Build. Since 2001, we have provided unparalleled in-house architecture and a collaborative team of Design/Build professionals.

Today, Ron’s sons, Jeff and Rusty own and operate the company. As a general contractor, we employ skilled workers and self-perform all cast-in-place concrete, precast concrete erection, steel erection, and rough & finish carpentry. Additionally, we have outstanding relationships with the premier subcontractors in the industry allow us to both set the pace of the construction schedule and maintain the highest levels of quality control throughout the life of the project. Fiegen Construction Co. has the expertise and experience needed to work on any size project.
