Pros
Being a large company, it has the leverage to gain the more prestigious projects all over the world.
Cons
Too much management, levels of management, procedures, policies, paperwork, but overall ONLY FOCUS ON PROFIT. They forget that profit comes from staff creating deliverable. There is zero attention to morale and developing a better product. The CEO is an accountant and runs the company like an accounting firm. I liken AECOM to the fictitious mega-corporations of movies and video games like OCP of RoboCop, Weyland Yutani of Alien, Umbrella Corporation of Resident Evil, and Cyberdyne Systems from Terminator where the only focus is profit at expense of everything else, including those who help make the profit. Every empire in history fails. AECOM will have its day.
