commentThe industry is still working through odd patches between the recession and what appears to be the early stages of recovery. As many firms search for clarity about markets and trends, ENR has re-engineered a new approach to the findings of the ENR Top 500 Design Firms survey. Look for new infographics with data and viewpoints from the nation’s largest design firms, presented in easy-to-read formats created to provide readers with fresh insights.
The Top 500 Design Firms list, published annually in April, ranks the 500 largest U.S.-based designs firms, both publicly and privately held, based on design-specific revenue.
