History

The future is determined by those who have the courage to shape it and are committed to working together.

In 1917, Henning H. Henningson was struck by how many people near and far needed better water works, sewer systems and electric plants. So he founded the Henningson Engineering Company in Omaha, Nebraska, adding value to the local community and inspiring positive change in neighboring states.

By the 1930s, our company was moving rural communities forward by lighting up their streets and helping them recover from drought. Just 20 years later, we added architectural services to our growing roster and expanded our engineering services to include resource management, community planning, transportation and more. 

Chuck Durham, a civil engineer, led our early era of growth, as we expanded from 15 employees to more than a thousand. Chuck went on to become a philanthropic giant, instilling the value of giving back in the fabric of our culture. 

Our entrepreneurial spirit continued into the 1990s, as our employee-ownership energized the company. By winning more global projects, we opened doors to share our talents with people around the world. 

Today, we continue to collaborate with our clients to push boundaries and uncover new possibilities.
