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.

Lesics never disappoints. Very easily explained and kept me interested through out the whole video.

I am also a civil engineer and projects like this is a dream for every Civil engineer. Mesmerizing ♥

Whoever come up with the idea building this tall building is a genius

Amazing how they made something so technically impressive but at the same also visually beautiful combing both in a seamless way.

sir, your explanation is very well. can you explain how to print billions of transistors in a single semiconductor surface.

Covered almost all points but few imp points missed such as: 1.Cooling system 2.design for pressure difference between air inside the building and outside air. 3.water management. I like the animation part a lot from your videos ❤️

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.

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!

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!!!

Watched a 2 hour documentary about construction of Burj Khalifa 7 yrs ago when I was a kid. This 12 min video is much simplified & also detailed as well. Keep up the good work. Lots of love.❤

This is really magnificent structure

I remember when I was a kid and this building was being built there were so many news and documentaries about Dubai's projects. This city felt like it was building the future in the middle of the desert, it was so cool.

And then the architect takes the whole credit. No one even know the name of Structural Engineer.

Engineering is a tool which can be used such efficiently, just stunned. Feeling proud to be Mechanical Engineering student.

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.

kudos to the Structural Engineer of Burj Khalifa.... Mr. William Baker... for making this engineering marvel... stand tall and strong.

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.

After watching this building being constructed for 6 years on line I went and saw it in person. The tour took us to the 124th floor, incredible views from the outside patio. It wasn't a windy day so we were able to enjoy the full view. The building is amazing, definitely worth the trip if you're into high-rises.

I love the thoughtful cooperation among architects and engineers this is a great piece of architecture and engineering. I think it will be a crime against humanity if I don't recognize the great explanations made in this video kudos for the deep info I'm motivated and inspired as an archy student...... Sending love from Zambia and you've gained a subscription from me✌️💚

One of my favourite masterpiece of engineering ever

Wow, so the design is not only based in the looks but specially based in the stability and existence of the structure. What a masterpiece of engineering!

That’s so crazy!!!! In physics class we did an experiment to create the tallest tower out of a limited supply of paper and this was my exact design I made. Except it was more of an elongated funnel shaped. And I got 1st place too

You pick different points to discuss than others and explain very smoothly. Thank you

Its all about intelligence of engineeers, courage of rulers, dedication of workers, respect ❤️❤️

Way of presentation with relevant pictures and animations is just amazing 👏🏼

Architecture is art at its finest 👌 It's one thing to build a stable tower, and onother to make it a space where humans can live Another complex engineering project

herobrine herobrine jesli to przeczytales to dzisiaj o piontej rano herobrine przyjdzie i rozwali twoj domek i ukradnie wszystkie diaxy chyba ze wkleisz to do 10 komentarzy w ciagu 2 godzin

Damn, those Secets are crazy

Yesterday I had been there to visit this beauty and for long time I look at this engineering miracle and think about it, today you came with the video 😍🎉💕thanks alot 🙏

absolutely mindblowing. i want to be an architect, and these videos which open the technical side of buildings have left me completely awestruck.

World would never be the same without engineers

Salute to the structural engineer.👍👍👍

The video production you have done here is no easy task too 👏🏻

Brilliant master piece, and civil engineers to make this structure sustainable.

Wow,brilliant! And what a feat for the builders, too! Imagine working on that!

You should add about its cooling system which was one of the biggest challenge for maintaining the temperature of a building which is in desert and contains mostly glass in outer layer...😬

Engineering's just getting better and better, science and technology will never end being developed as long as human still dominating the earth 😁

Been up it during day and night and the view, as well as the trip up, is breathtaking.

Even more amazing when you see it in person...

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 👀

Nothing compared to its original sewer system. A real marvel of engineering 🤣

Great explanation,👌👌👌 covered all the points that no one are covering around the KZfaq.

the animations are top tier

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.

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.

Excellent video and explanations! One quick comment: I think that the oscillations caused by vortex shedding are a self-excitation phenomenon rather than a resonance phenomenon.

I was in Burj khalifa last week and today all my questions answered, thank you for the video.

Whenever Lesics uploads, our day gets instantly better!! 😎

such a lovely and understandable explanation! thank you! 🙏🏽💜

This is really magnificent structure....Thank-you !!!

Engineering at its best, respect 100%

Amazing building As a civil engineer Many things to learn with these structure 🔥❤️❤️

Really great & experienced engineers 🙏

Hats off to the explanation and 3D rendering👍🏻👏🏻👍

All that clever design but no money left to connect the building to a sewer system. Trucks cart away the excrement every day. BRILLIANT !!

really great, what a masterpiece. And now let's talk about all the underpaid guest workers who worked there.

Just extraordinar!!!! Wow!

Intresting points....👍👍 Thank you for sharing....🙌🙌

This was very interesting to watch. Thanks to lesics for expanding our knowledge.

That was good explaination and nice graphics editing .👍 Could you make a video on the construction of " Statue of Unity" ( largest statue ).😁

That's amazing and complex for their time

We are really glad about this!! Would you guys make a follow-up on the Sydney opera house, please? I love how you explain concepts

All the great engineering feats of this tower explained in this video, it is hard to believe that they did not consider good sewage system is just as important

Lesics never disappoints, Keep up the good work. Lots of love.❤

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 🤷‍♂

As usual a very good , informative video by Lesics. Learning was never so easy as it is with Lesics. Best wishes for all of Lesics.

Burj Khalifa | All the Engineering Secets of the Mega structure Sanitation not included!

Brother this time you should make a playlist of burj khalifa's engineering.... Explain everything about this building.... Pls its my humble request.... I am very excited to know more about this beauty.... Love from india...🙏🙏🙏🙏

Great process video Amazing building, Nice engineering Graphic Quallity is good 멋진 영상입니다~~~~~~~~~

Thank you for the video. I am enlightened.!!

This raft and piles design is also very common in Indonesia where the soil is very soft, in every skyscraper constructions in Indonesia you can always see long concrete poles being driven down.

You're a constant reminder that people can be good. Lets take the moment to appreciate how much effort he puts into the content for us ❤️🥰🥰

Thank you for your efforts on these great videos!

best explanation ever and the demonstrations are perfect

It was a great engineering marvel. But technologically marvelous skyscrapers are typically uneconomical

One of the best secrets you missed is the SPIRE. That multi-hundred tons of steel object could not be put on top via crane or a helicopter ... how did they get it up there? :)

The animation was as marvelous as the Building

Thanks for sharing!

BURJ KHALIFA IS SURPRISINGLY BUILD BY SAMSUNG PLAYS A IMPORTANT ROLE IN BUILDING SAMSUNG🔥

*When it comes to the world of investing most people don't know where to start. Fortunately great investors of the past and present can provide us with guidance.*

Stunning engineering feats! Now i'm thinking of about the foundations though,to understand his solution 🤔

Man alive for sure the engineering of the Burj Khalifa is outstanding.... but your vids are GLORIOUS. Many thanks.

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

I won’t appreciate Dubai i will appreciate engineers for this Marvelous structure 😍

This is so interesting, thanks for your work!

Ohh gosh... wonderful animation. Thankz a lot

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 have been here. Awesome and beautiful city. Very clean and great construction. People are nice too.

Excellent Explanation ..!!!

Imagine if they can harness the energy of lightning.

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.

bruh, how tf do u manage to make such amazing videos every single time, love watching ur playlists, its like watching a favorite Netflix series, never gets bored

Wow awesome thank you so much for sharing this interesting information

It's a "modern engineering marvel" that there's no connection to the citys sewage system 😂😂😂😂

Their sewer system is not as marvelous as the building. Why? Was it million times harder to implement?

Awesome animations and great explanations

it truly is the strongest shape! real civil engineering!
