55 units collapsed
when I look at the aerial picture of the building it appears that only a small fraction of the building collapsed. Is that really 55 units in that small portion?
Yep, 55 units. This is almost half of the total 139.
The pile is actually larger than what is seen, because the lower garage are also collapsed. The pile above ground was about 40’ tall. Add the lower garage area and the real size is 50’.
12 stories is about 120’(10’/floor) plus lower garage is 130’.
After collapse, each floor is reduced to a little less than 3’total and figuring the cement floors in the equation, this leaves very little space for survivability unfortunately.
