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 70 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. With offices in Rock Rapids, Sioux City, and Sioux Center, Iowa; Sioux Falls, Rapid City, and Belle Fourche, South Dakota; and Luverne, Minnesota, we share that foundation with our clients.
As one of the top engineering firms in the country, DGR Engineering received notice that it was selected as a repeat honoree by PSMJ Resources, Inc. for inclusion in its 2025 “Circle of Excellence”. DGR Engineering has earned this honor every year since 2014.
