Nick Hetrick was AECOM's project manager on a Milford, Del., highway interchange job when he got an urgent call from his boss: A Delaware Dept. of Transportation crew on June 2 had verified an engineer's report that piers supporting an interstate bridge in Wilmington had tilted. Knowing emergency repairs were needed, DelDOT shut the busy bridge. After DelDOT and AECOM, its designer, determined the job's scope, AECOM Vice President Bruce Kay wanted Hetrick to be a point man for the firm.
