The Top 500 Design Firms

2009
Text size: A A

For large architectural and engineering firms, 2008 was the last hurrah for the boom market and the beginning of recession. ENR’s Top 500 Design Firms generated design revenue of $90.58 billion in 2008, up 12.36% from 2007’s mark of $80.62 billion. But many of the Top 500 began to feel the recession’s chill early. Of the 474 firms on this year’s list that returned a survey last year, only 304 showed revenue gains over 2007, while 166 saw their revenue decline, with four firms unchanged. This compares with last year when there were 382 gainers and 77 firms with lower revenue.

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.

The table below shows only rankings and firm name. For complete data from the Top 500 Design Firms list see the following links.
