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.
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 2019 “Circle of Excellence”. DGR has earned this honor every year since 2014.
New Airport Development
DGR led the design and construction phase engineering for the development of a new $30 million airport. Tasks included all phases of design and construction engineering activities.
Sioux County, IA
The project included full services for a 1.4 mile 115 kV line.
DGR employed a Geographic Information System (GIS) in conjunction with the U.S. Army Corps of Engineers to first determine the 100-year flood elevations and delineate the floodway boundaries.
Coordination between multiple entities to create a mutually satisfying layout of buildings, parking area, utilities and street access was a main element of the planning process.
Sioux City, IA
DGR Engineering collaborated with a long-standing airport engineering partner at the Watertown, SD Regional Airport to provide electrical design and construction services for the airport including runway and taxiway lights, lighted signs and airport electrical systems upgrades.
