The Zweig Letter announces 2007 Hot Firm List of fastest-growing architecture, engineering, and environmental firms

NATICK, MASSACHUSETTS-- Management consulting and research firm Zweig White Information Services has identified the 200 fastest-growing U.S. architecture, engineering, and environmental consulting firms for its annual ranking, The Zweig Letter Hot Firm List. This annual list features the design and environmental firms that have outperformed the economy and competitors to become industry leaders.

Construction management firm Toltest, Inc. earned the number-one spot on the 2007 List. Toltest and this year's other Hot Firms were recognized at a special reception at The Zweig Letter Hot Firm Celebration & Conference, held last week in Boston.

Mark Zweig, founder and director of ZweigWhite, says, "The firms that made this year's Hot Firm List should be proud. Even with the increase of 100 firms on the list to 200, it was still an incredibly competitive and successful group. Firms that commit to revenue growth while investing in marketing, information technology, and other infrastructure are usually the most successful in our industry. They have shown they have the ability to sustain their success, year after year. The hottest firms in the business--those with consistent growth and success at outperforming the economy and their peers--are the ones that attract top staff and the best clients."

The Zweig Letter 2007 Hot Firm List is based solely on gross revenue for both fiscal year 2003 and fiscal year 2006, as verified by financial statements or income tax returns reviewed by third parties. The list is limited to firms based in the United States and Canada deriving the majority of their revenue from the practice of architecture, engineering, planning, environmental consulting, or allied disciplines. Design/build firms are also eligible. Only firms that were in business as of January 1, 2003, and had 2003 revenue of $1 million or greater, were eligible. Firms were ranked from first to last based on percentage growth and dollar growth. Dollar growth and percentage growth were weighted equally to give both small and large firms an opportunity to make the list. Each firm's two rankings were added together, and the 200 firms with the lowest combined rankings comprise the list.
