As the pipes were connected to water tanks, as opposed to a public source, the flow could not be shut off. It is critical that we analyse the actions taken by professionals in the lead up to this event, whilst also considering the ethical issues at play, in order to understand and prevent similar failures in the future. Petroski states that with the modified connections of walkways to suspension poles, there was a safety factor not much more than 1, meaning no margin of error. It's mentioned in the report that there is some ability to reconstruct the collapse based on the evidence, I've looked in to chapter 5 and 10 where this is happens and while I don't understand a lot of what it's saying, I don't see anywhere it disagrees with the eyewitness reports of the fourth collapsing on to the second. But how could this have been overlooked?

The efforts by the radiologists and the coordination of medical help by the Eastman Kodak sales representatives were integral to the survival of victims and treatment of those injured. Surely these rules and regulations were put in place to protect the public from such disasters? The volume contains both the findings of the case and an excellent general discussion of responsibilities of the professional engineer.
Even the original connection design for the walkways was barely capable of sustaining the load of the walkway.

These same blessings… Words 1218 - Pages 5 Regency Hotel Case Study The Regency Hotel is a beautiful five star hotel that is located in Bangkok. This would have meant that that the two walkways could have supported a greater load and might not have collapsed. In July 1976, the Crown Center Redevelopment Corporation began the design and development of the Hyatt Regency Hotel in Kansas City, Missouri. In fact, costly is a weak word to be used here.
The first rod would run from the ceiling down through the upper walkway and attach there. At 40 stories tall, the Hyatt Regency would be the tallest building in the state of Missouri until 1986. In July of 1976, Gillum-Colaco, Inc. And seriousness in performing the calculations also became more serious. He assigned review to a technician on his staff; however, the connections were not detailed on the drawings and the technician did not perform calculations on the connections. In the collapse, the second and fourth floor walkways fell to the atrium first floor with the fourth floor walkway coming to rest on top of the second.
There are many men who have worried families, who are angry and asking questions. Based on test results the mean ultimate capacity of a single-rod connection is approximately 20. Aftermath One of the greatest errors made in the construction of the Hyatt Regency walkways was miscommunication. The third floor walkway was independently suspended from the atrium roof trusses while the second floor walkway was suspended from the fourth floor walkway, which in turn was suspended from the roof framing. And instead of healthy communication in which concerns and issues can be raised and taken seriously, the construction traffic was simply rerouted. The load of the second floor walkway was supported by the fourth floor walkway, but the second floor walkway is also connected to the second floor and maybe in other ways I don't know.
Both walkways later crashed to the lobby floor below, resulting in 111 deaths at the scene and 219 injuries.

The original design shown on the right shows how the rod travels through the connector and continues on to the next walkway.
All that had to be hoisted up the rods was the cross-beam. That night the stress became too great. The fabricator requested this change to avoid threading the entire rod. The disaster resulted in 114 deaths, 200 additional injuries, and as many unanswered questions from the victims' families and the survivors of the tragedy. According to the reciprocity principle the engineers and contractors need to think of the results of the actions and that people could be, and in this case were, seriously injured because of their inattention.
Gillum and Associates specified three pairs of rods running from the second floor to the ceiling. Photographs of the wreckage show excessive deformations of the cross-section. However, the load to be transferred from the fourth floor box beam to the upper hanger rod under this arrangement was essentially doubled, thus compounding an already critical condition. Yet, Gillum affixed his seal of approval to the revised engineering design drawings. The incident required a large number of medical personnel working alongside the rescuers.

This article has been rated as Mid-importance on the project's. The Hyatt Regency Hotel is now known as the Sheraton at Crown Centre. The design load for a fourth floor box beam-hanger rod connection would be 40.

The employee count for the hotel was around 700 and the moral of the employees was very high.
