If the part that collapsed matches the other side, then what collapsed was supported by only 3 columns over an open parking garage area. If one of those columns failed, then the remaining columns overloaded failed, then there was absolutely nothing to hold up all those floors.
That entire building has to come down now.
Edit: Guys, this is really bad. From the initial reports, it looked like only a small side of the building collapsed, one edge. But looking at the streetview here, the ENTIRE building along the length of the pool is straight up gone and pancaked. And that wasn't just 3 columns. This is a massive structural failure.

"More than 130 units and about half of those have collapsed".
