The Twin Towers no longer exist and there are just tales left behind. Manhattan got this skyline hall mark for just thirty years that was one of the most famous in the world. But there record – breaking height, the design and the basic fact of their presence were always subject to criticism.
The twin towers, both the North and the south were each roughly 1360 ft high, 1960 ft long on each side. Each of them had 110 floors and had 104 elevators and rested on foundations that were 69 ft into the bedrock and was a city in itself. Their construction required 200,000 tons of steel to give it flexibility so that it can endure heavy storms without breaking into pieces and 3000 miles of electrical cables to satisfy the distribution and consumption of about 80,000 KW per day. The structures were divided into three vertical zones for express elevator ascent. If we talk about the ventilation the towers design was made so to make it properly ventilated by placing 43000 windows, each 22 inch wide. And instead of walls or card boards, glass was heavily used in the structure, in total the facades required 215000 sq. ft of glass.
But before all this construction there was a need for 12,000,000 sq. ft land for the building in New York City which was not at all an easy task. The Designer Yamasaki provided 100 models for world trade centre before the two towers were selected, which presented a breakthrough configuration compromise. In the creation of Twin towers Yamasaki had to go beyond the traditional ways of construction and had to think of new ideas as this was not a simple project as other projects. This was the world’s largest project and he completed it successfully.
