- This building-the Burj Khalifa-which stands strong on loose, sandy soil braving the strong Arabian winds-is truly a modern engineering marvel. In this video, we are going to explore all the design secrets of the world’s tallest building, starting from its surprisingly simple hexagonal core. This incredible feat of civil engineering is even able to confuse the wind due to its unique shape and lightning with the help of modern technology. Let’s get into it.

After watching this, no one will think that Civil Engineering is not an exciting field. I didn't know that the spiral design was intended to reduce the effect of von Karman vortices. Thank you for teaching us useful engineering.
The Father of this dynamic is F.R khan aka Fazlur Rahman khan. He is a Bangladeshi Civil Engineer. Willis Tower he Designed .
The spiral design is very common around us, especially if you have a car with an antenna. They should have it. Electric lines on areas will have air spoilers as well.

I am also a civil engineer and projects like this is a dream for every Civil engineer. Mesmerizing ♥
Why not switch to a military engineer, though? All engineers have at least those two paths: either civil or military. You might be happier in the latter since not a lot of giant buildings are built, but military engineers always have fun.

Too bad it doesnt have sewage… stupid building
@@StrangerHappened 😂😂😂 there you will neither know as military person nor civil engineer.
The building has no waste water systems for either grey or black water. Every day there are dozens of tank trucks that carry away every drop of waste water. Engineering genius.
And then the architect takes the whole credit. No one even know the name of Structural Engineer.
There more then 40 engineers worked with each other

Amazing building. Just seeing this 3D model with the camera flying around triggers my fear of heights :) Incredible that such a thing exists, and in these conditions!
Didn't trigger my dear of height because I didn't really grasp the size of the building until he zoomed down to the entrance at the end...

You are giving so much credit to the architect. You have to understand that the hidden hero for this building to withstand against all nature's forces is the work of the structural engineers. It is the structural engineers that theorized and made it to happen and build the structural integrity of the building to make sure that people will live here and the surrounding city safe.
Agreed. Projects like this have hundreds of engineers working together, no one person should receive all the credit
But only a few architects around 1 or 2

3.water management.

I have always been fascinated by megastructures like these and I always wanted to visit this building and see it in person. This week, I was finally able to travel from Mexico and see it with my own eyes and… it is a MONSTER!!!!!
Just trying to imagine the workers assembling parts of the structure at such heights was mind blowing.
You can barely see people walking down the street but they look like tiny dots that look more like some type of tiny insects. Keep in mind that this was from floor 154 and that there are still more levels above. Just really impressive!!!
The Burj Khalifa, where both static and dynamic vector mechanics work wonderfully together to showcase the combined power of civil and aeronautical engineering. Wonderful video.

Thanks for all the explanation. It is a marvelous engineering indeed. However, the sewage system failed to accomodate the whole 828m height tower. Quite a flaw for such a megastructure.
The problem being that it is so huge, sewage system is too expensive to setup, so they just manually take out water by trucks

If anyone else wonders: my first thought upon hearing that the whole thing is built on sand was "soil liquefaction!" Apparently an assessment found that in case of an earthquake, soil up to sever meters deep could liquefy but not below that. Since the foundations are deep enough, we probably won't see the Burj Khalifa sink and topple over. Probably.

I have visited Burz Khalifa as a tourist. The building managers have kept Tabs which graphically explain how the building was designed and what were the challenges faced by the architects and engineers. Over and above these technical complexities, the building has adhered to some features of Islamic architecture. I don’t think I had understood anything. This video is wonderfully instructive. The narrator is so articulate and clear headed! The graphics are superlative. Many thanks again.
Islamic teachings actually discourage the building of tall buildings interestingly enough
@@se6586 Like the Tower of Babel in the Bible? When has that stopped anybody?
@@John_C_J no there is an end times prophecy which states a sign is the Arab people compete in building tall buildings

@@rawi4880 may you be granted understanding. These buildings are for pure vanity and serve no real purpose other than to flaunt wealth. Notice only western mentality leaning people are impressed with Dubai or any of these buildings. The UAE people do not research or develop or engineer they just give billions to British, German, French and American contractors to design & build these shaky buildings for vanity.

Back when I was in school, watching documentaries about this fascinating building and literal peak of human-made constructions was my greatest motivator for me to study civil engineering. For unrelated reasons, I ended up studying something different, but every time I look at such phenomenal results of human engineering and science, I feel a bit regret for not studying something civil/mechanical-engineering-related. Maybe, some day. Until then, at least I can still remain baffled by what we have achieved already.
absolutely mindblowing. i want to be an architect, and these videos which open the technical side of buildings have left me completely awestruck.

I can't be the only one with an irrational fear of being in tall buildings. I'd be so scared thinking of it falling down with me inside. I'd worry the ground isn't stable enough. I know it's natural for skyscrapers to sway a bit in the wind, but if I were in a building and it started to do that, I'd actually probably die of a heart attack. During my stay in Vegas on the 34th floor of a hotel, I had to remind myself daily that the building has stood for a long time and that it most likely won't suddenly collapse.

Great video as always.
Just wanted to mention that for some reason they didn't connect it to sewage system. So now everyday there's a line with trucks to pump out sewage 🤷♂
Amazing building. Great video 👍🏼
You forgot to mention that the sewage produced in the building has to be stored in a tank and transported away by trucks everyday, as there are no sewage lines in the region that can deal with the load the building generates -- what a marvel of engineering 👀
lmao old outdated story. The whole area the burj was built at (downtown dubai) was rapidly being built from nothing. when the burj finished the sewage system wasn’t complete so they used trucks to move the access waste temporarily and until it was complete. They haven’t used trucks for years but people loving bringing up this urban legend
This is false. Stop spreading false information
I won’t appreciate Dubai i will appreciate engineers for this Marvelous structure 😍
So you will appreciate the pyramid constructors but not the Egyptians?
WOW 😳 Awesome information. I love Construction.
I have been here. Awesome and beautiful city. Very clean and great construction. People are nice too.
As for the lightning rod. I think you need to double check this one.
The lightning rod is what we call ESE. Early Streamer Emission air terminal. It will not use a battery to generate an opposite polarity. More of like it is already inherent in the atmosphere. The ESE detect the type of polarity due to events prior a lightning strike.
To make it simple, lightning is generated due to opposite polarity that is why it hits the ground. Being said that, the polarity that attracts the lightning is already in the atmosphere near the ese. Light comes out when this two polarity meet.
The battery that you are talking about the video might be the lightning counter.
Well made video, but all of the technological procedures are well know in word of architecture and civil engineering. So Bill Baker din´t rly invent any of these solutions, he just used all the tricks in the book in a large scale. Still a great achievement of course.
I like to think it was not done before only because no one had an infinite money trick.
Engineering is rarely about doing new things, it’s about doing old things in new ways.

Wow awesome thank you so much for sharing this interesting information
Only engineering secret I know of Burj Khalifa is that they don't have a drainage system. So trucks are used to move it's sewer waste to treatment plant
Apparently, there are constant odors of human waste. I guess there would be if you needed a fleet of sewage trucks to remove tons of waste every day.
The Burj Khalifa is actually a great metaphor for the UAE, its politics and culture: marvel at the superficial modernity while ignoring the dirty systems which underpin it.
It's a myth and have no truth to it. This story about the Burj Khalifa not being connected to the municipal sewage system got its start in a 2011 book by Kate Ascher, The Heights: Anatomy of a Skyscraper. It have access to sewage system but in case of overload sometime they have to use trucks.
