About DGR Engineering

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

Founded by a simple handshake between friends in 1952, DGR has become one of the top engineering firms in the country. We are an employee-owned company with offices in Rock Rapids, Sioux City, and Ankeny, IA as well as Sioux Falls, SD.

Sixty-six years after that single handshake, DGR maintains the same spirit of passion, advancement and partnership on which the company was built. With more than 100 professionals and four locations in the upper Midwest, DGR looks forward to many more decades of helping businesses, schools and communities grow, and building the foundation for every day.
