Each year RECORD publishes the Top 150 Architecture Firms list, based on information collected by its sister publication, Engineering News-Record, for its Top 500 Design Firms Sourcebook. According to the latest survey, 2006 was a good year for architects, who reported a combined $8 billion in revenues. The 15 firms at the top of the list earned 37 percent of that, about $3 billion. To put those figures in context, it is helpful to know that architects’ offices with more than 100 seats make up only 2 percent of all firms, and yet these firms place 34 percent of total billings, according to the most recent AIA Firm Survey.
The accompanying table lists the amount of revenue each firm reported from its domestic and international work, and provides a total for them. Because the list captures many firms that have sizable architecture practices but are also involved in engineering and contracting, the percentage of revenue the firms say was derived from architectural work only is noted in the table. This total includes revenue from interior architecture, and also revenue that is passed through to other design consultants.
