We would love to learn more about your needs and find out how our firm can work with you. Evan Reis, a co-founder of the U.S. Resiliency Council, a nonprofit organization, says the biggest impediment is that unlike in Japan, buildings change hands frequently in America and the developers who build them do not see the incentive in making them more robust. "Its built with factors of safety and levels of redundancy which would make the most conservative engineer blush. Like many other skyscrapers such as the Willis Tower in Chicago and Bank of China Tower in Hong Kong, the design of U.S. Bank Tower is all based on the footprint's shape as shown below: Now given the shape of the bottom of the building, let's see how the whole tower takes its shape, note the color of each element: After each elements in the first picture pulled up to the certain heights the tower finally takes its shape.
