They are demolishing the center first then the outer frame. They are in no way attempting to remove the cells they are simply pulverising them.How are they tearing down the prefabbed rooms? I can't tell from the photo. Are they just knocking the things down in place or are they trying to remove the room unit then knocking down the remaining skeleton.
For those that don't know, the original Poly buildings and Contemporary Tower were built out of prefab rooms that were stacked by crane onto the building's skeleton. Not sure if the wings were built that way too.
