One World Trade Center stands in New York, New York, United States of America. It is currently the tallest building in the Western Hemisphere and the 6th tallest in the world. Construction began in 2006 and was completed in 2016. One of the big concerns in the design of this building was its height after the 9/11 attacks. Its structure at its peak stands at 1,776 ft tall with 104 floors and 71 elevators. It is made of concrete and steel rather than mainly steel, which is more common for skyscrapers, giving it greater core strength. They used about 200,000 cubic yards of concrete which has a very high compressive strength of 14,000 psi. They also used two tower cranes that rose with the building as it went up. It cost around $3.9 billion to build and is considered one of the most environmentally sustainable skyscrapers, achieving a LEED Gold certification.
