To industry giant AECOM, one is an important number. Not only is it the company's rank on ENR's 2011 list of top U.S. design firms, it also is part of the firm's new mantra, “One AECOM,” which represents its efforts to unite employees under a single identity.
AECOM was, until recently, the antithesis of a unified company, with its cornucopia of corporate cultures stitched together from a series of acquisitions and mergers over the past 21 years. In fact, AECOM's largest units still retained their former names–DMJM, EDAW, Earth Tech–until 2009.
