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

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 2017 “Circle of Excellence”. 

DGR's experience builds projects that not only our clients can be proud of, but also our employees, because we live where we work. We are an employee-owned company with offices in Sioux Falls and Yankton, SD and Rock Rapids, Sioux City, and Ankeny, IA and we share that foundation with our clients.
