This impacted the floors beneath and obliterated the entire corner of the structure. The investigation into what may be the deadliest accidental building collapse in American history has just begun, but experts who have examined video footage of the disaster outside Miami are focusing on a spot in the lowest part of the condominium complex possibly in or below the underground parking garage where an initial failure could have set off a structural avalanche. Unfortunately, it readily became apparent that the footings of the existing building, which consisted of decomposed rubble, did not offer sufficient resistance to the jacking loads.

Adjacent structures must be carefully monitored during underpinning operations, so if and when movements are detected, changes in methods or procedures can be implemented. Depending on the severity of the damage, it can cause the building collapse. >> The only structural corrective measure that was executed was to enlarge the existing footings so as to enable the structure to support the additional live loads without considerable settlements. Incredibly, it was the only structural element supporting the high-rise building. /F11 48 0 R While a number of bridges, overpasses and buildings under construction fail each year, the catastrophic collapse of an occupied building absent a bomb or an earthquake is rare, and investigators are struggling to understand how it could have come with so little urgent warning.
