Draper Aden Associates has once again been named among the Top 50 Trenchless Technology Design Firms in the United States and Canada, rising from 45th to the 33rd spot. The 2008 list was recently announced by Trenchless Technology News.

“This is the fourth time our firm has been included in the Top 50 Trenchless Design Firms,” said President and Chief Executive Officer Bill Aden. “I think this helps to verify that we are heading in the right direction to remain the firm of choice for our clients.”

Trenchless Technology Magazine, a Benjamin Media construction publication, is a noted trade publication in the engineering and construction industry. The Top 50 Design Firms listing is an annual slate that ranks the top engineering, architectural, and environmental design firms by the previous year’s revenue and number of trenchless projects.
