I was wondering the same thing, but Google street view (taken in 2014) doesn't show any evidence of such a big dip. How is that possible?? The only thing I can think of is that it's more of a "sag," where the middle has sunk 18" but the edges haven't moved much, but I'm not really satisfied with that theory. https://www.google.com/maps/place/Millennium+Tower+San+Francisco/@37.7901875,-122.3962408,3a,90y,237.99h,64.97t/data=!3m8!1e1!3m6!1s-35rB20DzRME%2FU7BvmBlYzUI%2FAAAAAAAAKgs%2FidvFTvbnBG4BG0iCULQUc1scg2DlGAkaw!2e4!3e11!6s%2F%2Flh5.googleusercontent.com%2F-35rB20DzRME%2FU7BvmBlYzUI%2FAAAAAAAAKgs%2FidvFTvbnBG4BG0iCULQUc1scg2DlGAkaw%2Fw203-h101-n-k-no%2F!7i11884!8i5942!4m5!3m4!1s0x0:0x9fe15ebd4a8300d8!8m2!3d37.7905058!4d-122.3961611!6m1!1e1 https://www.google.com/maps/place/Millennium+Tower+San+Franc...
