Welfl Construction was established in 1953. We are general contractors in South Dakota and Nebraska, and have done projects in Oklahoma, Kansas and Iowa. We build commercial, industrial, and educational facilities for manufacturers, hospitals, nursing homes, schools, churches, universities and water treatment facilities. As a franchised Butler Manufacturing Metal Building Dealer, we construct pre-engineered metal buildings. In order to have control of the schedule, we use our own forces for concrete, carpentry, and steel erection.
