Eric Sandler Ethical Disaster of the Hyatt Regency Collapse

Construction on the 40-story Hyat Regency Crown Center began in 1978, and the hotel opened on July 1, 1980, after construction delays including an incident on October 14, 1979, when 2,700 square feet of the atrium roof collapsed because one of the roof connections on the north end of the atrium failed. The collapse was the second major structural failure in Kansas City in a little more than two years. On June 4, 1979, the roof of the then-empty Kempar Arena in Kansas City had collapsed without loss of life. The architects and engineering firms at the two collapses were different. One of the defining features of the hotel was its lobby, which featured a multistory

These threads would probably have been damaged beyond use as the structure for the fourth floor was hoisted into position. Havens therefore proposed an alternate plan in which two separate sets of tie rods would be used. One connecting the fourth floor walkway to the ceiling, and the other connecting the second floor walkway to the fourth floor walkway. This design change would prove fatal. In the original design, the beams of the fourth floor walkway had to support only the weight of the fourth floor walkway itself, with the weight of the second floor walkway supported completely by the rods. In the revised design, however, the fourth floor beams were required to support both the fourth floor walkway and the second floor walkway hanging from it. With the load on the fourth-floor beams doubled, Havens' proposed design could bear only 30 percent of the mandated minimum load (60 percent in the original design). The serious flaws of the revised design were further compounded by the fact that both designs placed the bolts directly in a welded joint between two facing C-channels, the weakest structural point in the box beams. Photographs of the wreckage show excessive deformations of the cross-section. In the failure the box beams split at the weld and the nut supporting them slipped through. Since the construction process includes the work and ideas of many different
