Terracon Named #38 on ENR’s 2011 Top 500 Design Firms List

OLATHE, Kan. — Engineering News-Record (ENR) ranked Terracon #38 on its 2011 Top 500 Design Firms list, jumping three spots from #41 in 2010, showing Terracon’s consistent performance above industry average.

In addition to the Top Design Firm category, ENR ranked Terracon as the 18th largest design firm in the Top 20 General Building (commercial) market, 18th in the list of Top 20 Telecommunications design firms and 21st in the list of Top 100 ‘Pure’ designers.

ENR annually surveys the construction industry to determine the 500 largest U.S.-based engineering, architectural and environmental design firms. The rankings are based on design-specific revenue generated by each company.

Terracon’s total revenues were $329 million for 2010. Terracon’s top four sectors (State/Local Government, Commercial/Retail, Industrial/Agriculture and Institutional) accounted for 76 percent of total revenues. In addition, the Federal Sector grew rapidly with nearly 70-percent growth over 2009, and a 700-percent growth from 2008.

During 2010, Terracon acquired four highly-reputable companies: ESA Energy Systems Associates, Inc., Midwest Testing Laboratory, Inc., Stafford Consulting Engineers and Geotechnical Engineering Group, adding a total of 12 offices.

“In the context of the economic conditions, we had a very successful 2010,” said David Gaboury, P.E., president and CEO. “Our even-stronger national network of local offices and dedicated employees continue to be the source of our success. Terracon’s growth is due to the commitment of our employees to be responsive to clients and provide quality services.”

Terracon is an employee-owned engineering consulting firm with more than 2,700 employees providing geotechnical, environmental, construction materials and facilities services from more than 120 offices in 39 states nationwide. For additional information about Terracon, please visit
