Over the last one hundred years we've come to realize that where we're going has a lot to do with where we've been. That if we strive to do what's right, we can't go wrong. We started making history in 1917, when the Henningson Engineering Company brought power to the plains.

HDR turned 100 years-old today. A century of pushing the boundaries of what’s possible. A legacy of bringing innovative solutions to every project – no matter the challenge. A future of collaborating and creating the only way we know how. Together.
