At DGR Engineering, we build the foundation for every day. From roads and power lines to where parks and water intersect your life, we make it all work, and we’ve been doing it for more than 65 years. Our projects in civil engineering, water systems, electrical distribution and surveying can be
found all across the Midwest.

We build projects that both our clients and our employees can be proud of, because we live where we work. We have offices in Rock Rapids, Sioux City, and Ankeny, IA as well as Sioux Falls, SD and we share that foundation with our clients.
