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 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. 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 2022 “Circle of Excellence”. DGR has earned this honor every year since 2014.
