Good questions, but I wouldn't say the "only potential problem" would be unusual loading.
I've heard reports that they were running jack-hammers. I would assume they were breaking up concrete. I wonder how many were being used and the time-frame of their use in relation to the collapse? One cannot ignore the possibility of destructive resonance weakening the structure and contributing to the collapse.
