For more than a century, SOM has been a supporter of high-rise buildings. It is said that in every five skyscrapers in the world, there will be one designed by SOM engineers. In Chicago, architects completed the design of the appearance and structure of Jinmao Building. They ingeniously applied the special form of "8" to the design of structure and architectural appearance. On February 28, 1998, the four year Jinmao Building project was completed. The completed Jinmao Building is a super tall building with three floors underground, 88 floors above the ground and six floors of group houses, covering an area of about 290000 square meters and a total height of 420.5 meters. It is the highest skyscraper in China in the last century. It integrates modern office buildings, luxury five-star hotels, commercial exhibitions, high-end banquets, sightseeing, entertainment, shopping malls and other comprehensive facilities. As a new landmark of Shanghai, Jinmao Tower is the first milestone for Chinese people to realize their dream of skyscraper.
