Transcript of Petronas towers
design by Dóri Sirály for Prezi
The builders couldn't import enough steel so they used super high strength reinforced concrete. It had double the sway reduction against the wind but makes the building twice as heavy as the foundation. Built on the worlds deepest foundation. It is designed to withstand mostly wind. Each floor plan makes an 8 pointed star and is based on simple Islamic shapes to represent their religion. It has 88 stories and is 1,483 ft. tall.
It takes 90 seconds to travel from from the basement parking lot to the top floor.
The highest floor in the sears tower is 200 ft higher than the highest floor in the petronas tower.
There are about 32000 windows all together and it takes a month for window washers to clean all of them.
The sky bridge was one of the most difficult features to build on the tower. It has a sliding support that allows it to move side to side so the separately swaying buildings don't rip it off. They had to separate the bridge into 493 separate pieces to ship it to kuala lumper and took 30 hours to assemble.
The sky bridge
It was used for work, shopping, restaurants, and entertainment. At the bottom floor on one of the buildings, is a massive concert hall. It has more than 8 million square feet of shopping and entertainment area. It has 14,000 to 22,000 square feet of office space per floor.
What its used for
The Petronas Towers are located at Kuala Lumpur, Malaysia
