200 ft. x 200 ft. One World Trade Center rises from a footprint that is 200 feet by 200 feet, the same dimensions as the original Twin Towers. It is intended to reach the same height as the original towers, with its main roof 1368 feet (417m) above ground. The building will also contain three other smaller roofs called "milllions". The top of this central tower will contain the office space, while the remaining two tops will contain restaurants.
Construction on One World Trade Center began in 2009 and it is expected to be completed in 2014. The developer of the project is World Trade Centers LLC, which is composed of Silverstein Properties Inc. and KDC Development Company LLC.
The total cost of constructing One World Trade Center has not been released. However, based on the price tag of its twin buildings, it could be between $3 billion and $4 billion.
Why build another world trade center? In 2001, after the terrorist attacks on New York City's World Trade Center destroyed most of the existing trade centers in the city, officials decided to rebuild one center instead of trying to replace them. The new World Trade Center will have nearly 5 million square feet of rentable space-more than any other skyscraper in New York-and will be able to handle all types of commercial transactions, including handling cash.
208 feet long by 208 feet wide. The WTC buildings were each 110 storeys tall. 1 WTC (the North Tower) was 1,368 feet tall, with a giant 360-foot-high TV antenna installed in 1978, and 2 WTC (the South Tower, which housed the observation deck) was 1,362 feet tall. The towers' length and width were 208 feet and 208 feet, respectively. The two towers stood side by side in Lower Manhattan.
The Twin Towers were the tallest building in the world for 10 years after their completion in 1973. They were surpassed by the Sears Tower in Chicago in 1979. The World Trade Center complex included an underground parking garage that could have fit about 500 cars. There was also a small retail space below the garage that sold food and souvenirs.
When they were completed in 1973, the Twin Towers were the first skyscrapers to exceed the height of 50 stories. Their size and shape made them particularly visible from far away, even at night when they were illuminated, and this led to many rumors about other things they were supposed to be able to see from far away including the Titanic in the ocean flooringsurrounding New York City.
The truth is that nothing can be seen from far away - especially not at night! They are best viewed up close because you can really appreciate how thin the walls are on some floors.
There are actually three different types of walls in a tower: load-bearing, non-load-bearing, and interior walls.
Though the WTC towers stood more than 1,360 feet above street level, the structures' bases were really 70 feet into the earth, and one had a 100-foot-tall antenna atop it, so with 205-foot widths, they had a lot of [external] space facing the wind," the engineer explained. "That's why they could be so tall. They had to be strong enough to hold up all that weight on top of them.
The WTC towers were actually composed of three separate buildings inside of each other. The first two buildings were identical and contained the offices and apartment complexes. The third building was added at the top of these structures to house various retail stores and restaurants. This third building was also never fully occupied, so it left lots of room for additional floor space in the future if necessary.
The total height of the twin towers was 1,368 feet (417 meters), and they were made of steel and concrete. The antenna on top of one tower was 461 feet (140 meters) high.
The answer depends on how you define "maximum load". If we limit ourselves to pure physics, the answer is clear: The strength of construction material will not allow for any structure to carry more than its own weight. However, most things other than gravity affect how much weight a building can support.
The columns at the base of the tower's foundation were around 35 feet (11 meters) long. The twenty-four perimeter columns of 1 WTC had all been completed by November 1, 2009, and work of the second story (the first floor above ground level) was virtually complete. The overall height of the building, including its roof, was 440 feet (137 m).
The exterior columns of 2 WTC were 42 feet (13 m) long, while the interior columns were 30 feet (9 m) long. They were made of steel with a diameter of 6 inches (15 cm), but some of them were actually hollow inside to reduce their weight.
The average depth of the hole dug for each column was 60 inches (152 cm), and it took about 200 truckloads of dirt to fill them in.
They were built using the peripheral column method, whereby columns along the edge of the building are smaller than those in the center. This allows for more open space in the building and increases visibility from outside the structure.
Columns are an essential part of any skyscraper, since they provide support for the building's weight. There are two types of columns used in high-rise buildings: internal and external. Internal columns are the ones that hold up the floors; they run through the body of the building itself.
The Twin Towers—the original 1 World Trade Center (the North Tower), at 1,368 feet (417 m), and 2 World Trade Center (the South Tower), at 1,362 feet (415.1 m)—were the highest structures in the world at the time of their construction. They were surpassed by 472-foot (143 m) Building No. 7 on the site.
1 World Trade Center was completed in 1973 and 2 World Trade Center in 1971. The buildings were originally known as New York City's Twin Towers because of their identical design. They were renamed after the September 11, 2001, terrorist attacks that destroyed them.
Building No. 7 was planned from the beginning to be part of the World Trade Center complex but wasn't opened until 2014. Its height of 1,776 feet (541.9 m) made it the tallest building in New York when it was completed in 1973.
It's been said that there are two types of people in the world: those who remember what happened on September 11, 2001, and those who don't know where New York is. Well, now you know!
New York City has risen from the ashes twice before: once after the British burned most of Manhattan during the War of 1812 and again after World War II when nearly all the buildings on Manhattan's West Side were destroyed by fire or bombing.
