I will say this regarding the ground water. You mentioned they were going through pumps. Again I think a clear indication of ground water coming in which further indicates a damaged slab. It is possible (likely) that during stoms when the power goes out and the pumps go off. The rising flood waters are creating hydrostaic pressure on the slab. Again, assuming a monolithic pour the garage is going to try and float. Obvisouly it can't float wih a building sitting on top of it so eventually something fails which would be the concrete but would remain held togetehr by the rebar. We would expect the water infiltration to get worse as time went on after each storm and rise of tide. as the cracks got larger pumps running more often, larger pumps needed to keep up with the amount of water.
Also regarding the firemen in ankle deep awater. Remember the intial collpase which collapsed the garage ceiling occured about five minutes before the building collapsed. ruptured a water line that appears to be 4" or 6" round. This can be seen in this video
