In reading up a bit about the architect, he sounds shady. He apparently fabricated his resume to include an honorary doctorate from a school that doesn't exist. For a $1 billion purchase price, I would think the owners should be concerned about something like fabrication of a resume by their chief architect (who is totally unproven in the area of skyscrapers).
