call HART crazy .. but
A nearly finished 13-storey building toppled over June 27, 2009 – almost intact – killing one worker … Here’s what happened:
(1) An underground garage was being dug on the south side, to a depth of 4.6 meters
(2) The excavated dirt was being piled up on the north side, to a height of 10 meters
(3) The building experienced uneven lateral pressure from south and north
(4) This resulted in a lateral pressure of 3,000 tons, which was greater than what the pilings could tolerate
Building toppled over in the southerly direction
First, the apartment building was constructed
Then the plan called for an underground garage to be dug out. The excavated soil was piled up on the other side of the building
Heavy rains resulted in water seeping into the ground
