So I was wondering this as well. Walking by the building I never noticed. Checking Google Maps Street View I also couldn't tell. So I'm curious how this works.

So I was wondering this as well. Walking by the building I never noticed. Checking Google Maps Street View I also couldn't tell. So I'm curious how this works. It's sank a total of 16 inches; 8 of which happened after it was completed. So why does it not look funny? Am I thinking about this wrong?
