Including comparisons to neighboring buildings with a very well done chart. And this frightening statistic:
On Friday the transbay authority released a report by the engineering firm ARUP, showing that the Millennium Tower is four to five times heavier than any other building in the area with a similar foundation, including 100 First St., 199 Fremont St. and 555 Mission St. Building weights are measured in kips — 1,000 pounds — per square inch of pressure on the soil below. The tower at 555 Mission, for example, is 487 feet tall compared with 645 for the Millennium, but it exerts 2.4 kips per square inch while the Millennium exerts 11.4 kips.
