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. Design criteria were also changed for effective planning to reduce the possibility of failure due to progressive collapse. Tunnel forms were used by the construction team for casting concrete on the floors and in the walls. The curved design of the Vdara Hotel in Las Vegas, designed by Rafael Violy, basically turned the building into a giant magnifying glass, intensifying light so much that it harmed hotel guests and earned it the nickname "Death Ray Hotel.". /FirstChar 32 Work finally ceased in the 1600s, but additional reinforcements have been added as needed over the centuries to the current structure.
