Our Foundation
Built on solid relationships, a strong work ethic and stable business
practices, DGR creates that foundation for every day with its clients.
Our team of almost 100, specializing in civil, water and electrical
engineering and surveying, started more than 60 years ago. As we
grew, we helped the companies and communities we work with
grow as well.
Starting in 1952 in Rock Rapids, Iowa with a handshake
between friends, DGR grew into an employee-owned
company with a team of engineers and surveyors
working across the Midwest. With offices in Rock
Rapids, IA, Sioux City, IA and Sioux Falls, SD, we
still work with many of the first communities we
did business with when we first started, while
expanding to new projects to help
communities, schools and businesses
across the region grow with us and
build a foundation for every day.
Trusted. Professional. Solutions.
