You were originally the GC's project engineer (PE) working for PM1 and are now thrown into the position of the GC's new project manager (PM2). There is also a new architect (Arch2) who was previously a draftsman working for the old architect. The new architect is a "yes man," and knows the way to get more work from the developer is to take their side on all issues. Your predecessor is also pushing you around from the client's side of the table, claiming everything was "included" in the bid.

How do you deal with all of these new "clients" who obviously know more about the project than you do?

please answer the underlined question in on paragraph.
