9/11 Research Paper
Many people believed that the Twin Towers would never collapse and that it was invincible due to the complexity of its structure. The North Tower was constructed in December 1970, followed shortly by the South Tower in January 1972. The complex design of the World Trade Center was conceived as an urban renewal project and were used to restore confidence and help bring a halt to the decline of lower Manhattan. The 9/11 terrorist attack was a series of four attacks on the United States on the morning of September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and cost at least $10 billion in property damage and infrastructure. The greatest factor that contributed to the loss of life of 9/11 was the construction of the towers

The fire that was created at the World Trade Center was far greater than anyone would have anticipated and, “Despite the gravity of these doubts, the evacuation policies at the trade center assumed that the towers were sturdy and fire-resistant,” (Dwyer and Flynn 69). Considering the fact that many buildings codes were not a requirement for the World Trade Center due to its complex structure, not fireproofing the towers became more acceptable, especially because no one had thought that the towers would be brought down by a fire. After the 9/11 terrorist attack, many building designs were modified to become safer because the International Buildings Safety Codes adapted their codes in order to keep all buildings safe in case of a fire occurring. According to International Codes, as a result of the 9/11 attack, there have been some changes made to their code. Some of these changes include having a higher standard for fire resistance in high-rise buildings more than 420 feet tall and robust fire proofing for buildings more than 75 feet tall, which will be less likely to be dislodged by impacts or explosions. As a result of these changes to international building codes, there have been many preventative measures taken and it has had a major impact in making sure that more survive situations similar to the 9/11 terrorist
