Discover the engineering innovations that made building Burj Khalifa, the world’s tallest skyscraper, possible.
--
In 2004, construction began on a new building in Dubai, promising a revolutionary design that would dwarf the rest of the world’s skyscrapers. Five years later, the 828-meter Burj Khalifa was complete, surpassing the previous record-holder by over 60%. What innovations allowed for such a huge leap in height? Alex Gendler digs into the architecture of this unprecedented project.

@spacecat7827 3 жыл бұрын

2 lives lost, only one of them was an accident, they were paid 10 dollars for 12 hours of work, they weren't allowed to leave because the supervisors withheld their passports from them. Don't say ''well, only a life was lost'', as if those two lives meant nothing, as if their hard and grueling work meant nothing, as if the way they we're treated meant nothing. They were barely treated like workers, more like slaves.

I used to work at the Petronas Twin Towers. Every Friday, the facility managers would conduct special prayer sessions (I can’t remember what it’s called) to appease the spirits of the workers who died constructing the building. Apparently, they even had the Towers blessed by religious personages on regular basis. Many have claimed to encounter ghosts but I myself never did.

So they planned 3 major express elevators, like you mentioned, 3 major floors ( I don't remember i think 42 , 120 ad so on) with a dozen of minor elevators to complete the Trip.

i've been to Dubai several times, and one thing i can say (being related to this video) is there is A LOT of skyscrapers. They are so tall you have to turn your head all the way up in order to see tops of the buildings. If you keep your look straight it is very simmilar, as someone just stretched them out of sight. It gets even worse with Burj Khalifa, as if you stand near its foundation (The Dubai Fountain at one of Dubai Mall exit in my case) because it feels like someone keeps stretching it out of sight, until you are almost looking straight at sky, you can barely see top of it. It was mindblowing to remember that you are standing next to 828 meter building.
