The 2015 Top 500 Design Firms 401-500

For ENR, it was a watershed year. We recognized individual contributions to the industry by citing people who "Made Their Marks" in 1965. In addition, fresh off the first ENR Top 400 Contractors list in 1964, ENR published its first-ever Top 500 Design Firms list.

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