A Real Design/Build Company


Fiegen Construction Co., a second-generation family-owned and operated business is proud to carry on a heritage started 45+ years ago. The company, founded by Ron Fiegen, started with a foundation of steel and precast concrete erection, heavy rigging and crane rental services. This work continues today as the backbone of their general construction work, but Fiegen Construction Co. quickly evolved into a full-service general contractor and most recently combined architecture and construction under the same roof, a method known as Design/Build.

Design/Build provides Clients with a single committed Team that has full responsibility from conception (design) to completion (build). Having these resources as a single entity provides our Clients with a simpler, more streamlined process that saves both time and money, reduces oversights and overruns, and provides a more informed decision making process.
