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 and
Sioux City, IA as well as Sioux Falls, SD and we share that foundation
with our clients.
As one of the top engineering firms in the country, DGR received notice that it was selected as a repeat honoree by PSMJ Resources, Inc. for inclusion in its 2021 “Circle of Excellence”. DGR has earned this honor every year since 2014.
