ENR 2018 Top 500 Design Firms 301-400
The market for major design firms is growing and is poised to continue to grow for the foreseeable future, but the sense of euphoria seen last year has faded. One year ago, most firms expected a burst of new business from tax cuts, deregulation and a promised infrastructure bill in the wake of the election of President Donald Trump. Now, design firms are focusing more on their key markets and systems to deliver their services as efficiently as possible.
