With a height of 1,776 feet (significant in its reference to the year of America's independence) the One World Trade Center is the main building of the new World Trade Center complex planned as part of the Ground Zero reconstruction master plan for lower Manhattan. The 105-story super-tall skyscraper is currently the tallest building in the Western Hemisphere. In addition to the complex design of tall buildings, the aftermath of the September 11 collapse and the existing conditions of the infrastructure at Ground Zero also added many challenges for the design and construction team. As principal-in-charge of analysis and design, Dr. Rahimian said that One World Trade Center will be unprecedented in terms of life safety and security and will set a new safety standard for the design of tall buildings. The structure consists of a robust, high-strength concrete core paired with a highly redundant perimeter steel moment frame to provide column-free interior spans for maximum flexibility of tenant use.
