OLATHE, Kan. —  Engineering News-Record (ENR) ranked Terracon #39 on its 2012 Top 500 Design Firms list, showing Terracon’s consistent performance above industry average, with a ranking of #62 ten years ago.

“We are proud to be #39 in the country,” said David Gaboury, P.E., Terracon president and CEO. “For the past two years, we have achieved double-digit growth.
