About Us

KLJ provides multi-disciplinary engineering and planning services that set the standard for quality and client satisfaction. We deliver innovative and practical solutions for local, regional and national companies.

To say a company has evolved implies that it has adapted, transformed, become more efficient, and quick to identify next steps. That’s what’s happening at KLJ. With 85 years serving in the engineering industry, we look back – from a small company working across the Dakotas to engineering infrastructure across the nation.

Our evolution has helped us solidify our mission to improve the lives of people and communities – by engineering progressive infrastructure. We are perfectly designed to thrive in this environment. Adaptable enough to evolve with the times.

Engineering smart for a solid future. It’s second nature at KLJ.
