Man Dubai is such a meme. Land doesn't want skyscrapers.. But money can solve anything I guess.

love that there's not really a intro to the video, just straight up to the point, no clickbait. love it

Thanks to the people at Lesics for reconstructing the entire building for this video!

They brought "building on sand" to a whole new dimension.

I love the use of standardized measurement units for easy understanding of scale - thickness of two human beings, depth of 10 story building, depth of 10 Burj Khalifa floors.. I was disappointed when the settlement was measured as 5 cm (approximately one small kiwi).

2 years for constructing a foundation and studying its situation explains why and how important a perfect foundation is for skyscrapers nice video 👍😃

I think another design to overcome the wind striking the Burj Khalifa is actually the shape of the building itself the engineers called it somewhere in the lines of "Fooling the wind" and the design is a sort of "3 leaf clover" and as it goes up higher each petal gets smaller and smaller in a rotational order this design basically prevents vortices from forming on the sides of the building... that was quite a rough explanation of what I know about the tower design so I hope you understood at least a little bit

I absolutely love how you make a 3d model of the creator and use it for the demonstrations, so awesome.

Kudos to all the Animation Software Designers and people who worked on that video 👍 Amazing job ✨♥️

I work on ships as an electrical officer and this exact method is used to reduce corrosion of hull, it is called impressed current cathodic protection. Older ships used sacrifical anodes( zinc anodes placed at location on hulls ). Intrigued to know that its also used in the world tallest builiding.

A marvel of engineering design with some very patient intelligent and hard working labor force behind the construction of some of man-kinds most incredible building structures. The "everything" that goes into making these tall buildings stand up into the clouds is unbelievable for a majority of those who are not familiar in the construction field. Thanks to the people who put together these videos and for those that have the pleasure to watch them, its great that you have described the details of such in layman's terms(simple and easy to understand). Otherwise there would be a lot of questions that I'm sure would be overwhelming itself, let alone the questions that arose before they began the construction process on such an enormous achievement. Incredible.

Wow, my standing ovation to the hardworking minds of the engineers

Thank you sir for the wonderful explaination.... I'm astonished by the amount of work and effort but that explains how this marvellous structure has been standing this long .

This channel really educates me about so many things I was curious about , This is what I was looking for!

Very well explained. Thanks so much!

amazing how much work and effort has been put into this building!

Awesome video... I could watch those kind of videos all day... So as long as you keep producing.. I'll keep watching...

I have so much love for engineers & technicians who made this happen...

His thumbnail is my childhood imagination, thanks for completing it 😌

thank you very much for all your amazing informative videos! :)

This is an incredible engineering!

Possibly the best overview video on deep mat foundations that I've seen. One question - why wouldn't they use a composite rebar to avoid the issues with corrosion? In theory it would be much less complicated, lower maint, and less expensive.

Cathodic protection also used on underground fuel lines at airports. Awesome video. Great animations and well explained!

I counted 3 times when Burj Khalifa dropped to the ground and shattered to pieces. That was nice to watch.

Really appreciate the efforts to explain a concept with animation. Is Blender used to make such beautiful animations ?

Great explanation, really interesting. Funding the maintenance will be what breaks this building.

Wow it's really, awesome engineering , Thank you lesics!

New “Subbie” I love how he explained it clearly👍👍👍 Indeed, there’s nothing impossible if you have so much money to spend.😀😀

So good :) thoughtful design + accurate animation

Thanks lesics , Now I can make my own burj khalifa myself DIY. I had the same problem with soil but when i searched on youtube this video cane up . Once again thanks

Wow. This is highly impressive can't still wrap my head around it

"Ok guys, it's time to connect the building to the sewage system..."

Extraordinary engineering, insanely inspiring!!

I am definitely sharing this with my friends when I get back

That was downright excellent and clarified one of the many holes in my ever growing knowledge gaps 😂 Top notch work. Clear, concise and amplified all points of interest with surprising clarity 😊

Awesome video! Thanks for using the metric system 😊

Your 3D animations are amazing and quite easy for me to understand things. Loved it❤ one request, can you make how petrol pump nozzle auto cutoff works in 3D? Please😊

Just became your member :D Such an interesting visualization. Thank-you for sharing this.

Great to see Mr. Bill Baker hosting this episode!

Thanks 🙏 for making my day with engineering vids😌

If we didn't have smart people like this. Humanity would be no where. Phones, internet, cars, etc. Just crazy to think about

Great work Lesics ,,, 🙏🙏

Thanks for this very well explained and informative video. An enjoyment to watch.

I work in engineering and work on piles, concrete and reo. I think this video provides a very good basic overview. The geotech side iften gets over looked but is essential.

Interesting steps they took to offset the concrete temperature rise while it cured (Ice & night pouring). Many of the "rebar" at Boulder Dam were pipes. After a section was poured, they pumped cooling water thru them so the heat could be rejected using external cooling towers. When finished, they filled the pipes with concrete. Impossible to do a single pour for Boulder Dam - too big. Instead, they made each section a complex shape that interlocked with the next sections. It's called a "sacrificial anode"; all boaters know about them. We use zinc sacrificial anodes to keep our propellers from going away. Use of titanium is very interesting.

Kudos to the engineers and workers

Теперь все понятно! Я думал как так можно в пустыне так строить ! Молодцы!

It will topple over one day.

Very well explained. Thank you very much.

Amazing engineering and problem solving

Good explanation sir. Watching from Bangladesh 🇧🇩

Interesting....never knew it's foundation needs to carry electricity to prevent seeping sea water from corroding it

This video has excellent clear explanations that drew my curiosity despite not being a civil engineer.

Thanks for the information. 🙏🏻

It is so satisfying when you are from same field and you know all the terms and thing here talking about

The tower may have been a product of oil-rich ambitions, but you can't deny that it is an engineering marvel.

You have to appreciate the amount of work and thinking that Went into that building

Amazing enginnering hidden in tallest building in the World. People are incredible. We overcome hardest demands.

The piles will be corroded anyway with time, wont it? I mean, given maybe a few centuries, they almost certainly will be. Is there a plan to rebuild them slowly in the future or something? I caught myself watching videos from the past century or two and it seems we dont ever stop and think about the future of our buildings like that, but they will be around.

They put so much careful planning and smart design into this building, yet there are still no guarantees. The universe is constantly drumming up new chaos. Only time will tell if they took sufficient precautions.

Thanks for a well put video with education.

Thanks to this video, I realized how vulnerable the building is.

Most of those solutions are very innovative and sophisticated, but to build a forest of piles below a new construction is been applied extensively in Venice since its foundation to counter the downwards push on its silty underwater ground. The Santa Maria della Salute bassilica is thus built upon a forest of about one million of wooden piles that prevent its enormous mass to sink into the lagoon ✋

I thought it was gonna be some kind of dynamic actuators that compensate for wind and make it all crash down if it loses power. This is much more reasonable!

Very strong video, thanks!

I would have thought the ice cubes in the concrete would act similarly as air bubbles, thus the concrete would be compromised. On reflection: the curing (concrete)would be slowed by melting the ice, while vibrating of the foundations (during pour) would work the water (ice) throughout the concrete. I also believe that electricity from the atmosphere would also be drawn through the building to ground. Oops: was I thinking too loud?🤔

Stocks, bitcoin, forex and cryptocurrency are falling and bond yields are rising, but markets still don't seem convinced the Federal Reserve will pursue plans to keep increasing interest rates until inflation is under control. I'm still at a crossroads deciding if to liquidate my $150,000 stock portfolio, what's the best way to take advantage of this bear market?

Amazing truly. Looks like basic foundation but crazy how they must account for the salt water. That’s some big brains on the job

Wow extremely useful information. Thanks

Very interesting! The principle used here is the very same as in every hot water tank. Sacrificial anode. Out of sight, out of mind. Every building has a final life. This will eventually open up to new minds on how to renovate or re-certify say after 40 years or so. Surfside Florida will be long forgotten when this one comes down. Btw: this building is not connected to a sewage system. Re-finance options were all exhausted well before. The Eiffel Tower is still standing because its footprint vs height does not violate the laws of physics. Standing by for the ultimate news from this region on the day to come.

As a geotechnical engineer, I find Burj Khalifa really fascinating

Thanks for sharing 👍

Awesome video I am your new subscriber I really enjoyed the video awesome work ❤️

There are other buildings that have relied on friction piles (I believe SF's MiIlennium Tower is one), but perhaps not deep enough, and they failed to provide the anticipated support.

This is a great video. A couple of suggested clarifications: 1. This is impossible to drill with auger excavator, it would have to be with drill rig. 2. Polymer slurry is same density as water, but has a Marsh Funnel Viscosity at that is 3-5X that of water hence the polymer doesn’t seep into the soil and doesn’t allow water to enter, provided the water head inside the shaft is higher than outside. They likely only had a small temporary casing to work around the shaft and keep up the slurry head. 3. In theory, steel is inert in alkaline medium like concrete, so provided the concrete cover is met, it shouldn’t rust - this also depends on the concrete exposure type to resist things like salt. In some cases they use galvanized rebar for extra protection or fiber reinforced polymer rebar which has higher tensile strength but brittle, so mostly used for things like TBM head walls. Having said that I had never heard of this system. Thanks for sharing

Fascinating!

thank you for nice video 😊

They also used friction piles for the Millenium Tower in San Francisco. Good luck!

Great animation that i had ever seen, great work.....Of this channel

That was a great video!

Let's design a foundation system that if we do not constantly feed electricity to it, it collapse. Such a brilliant idea.

always wondered how thats possible to build such a city on basicly sand.... very good explained :) but im very curious if this rly will hold up for the next 100 years

thanks for sharing this information for future aspiring villains.

Interesting stuff. I learned a lot!

What glue did they use for burj khalifa foundation elmers .?

You always impress me with your animaitons 💯

Does this mean that hydrogen gas bubbles up from the cathode, and what about reactive corrosive sodium?

Trading with Mr Jackson Williams was never a regret to me. All thanks to him, he is the best I have ever seen.

Your presentation are very nice 🙂 I request please continue and make more videos on CS topics

شكرا على المعلومات 👍🏻💯

I am supposing this method has been done many times in the building of bridges. Some bridges are built over the sea that has salt water from the ocean. Pretty sure their foundation could be on sand or weak soil. However a bridge probably doesn’t have as much weight pushing down or as too heavy as this structure. To me it would have made more sense to build it outward rather than upward. That way the mass of the building is spread out making it easier to balance. I think for the tallest building record would be better built in a mountain with solid rock. 😝

Okay but why isn't the Burj Khalifa connected to the sewer system?🤔

That was very interesting 👍🏼

I was not planning to visit that building anytime soon, and now after watching this clip, even less.

So what about the static electricity from the wind and sandstorms? How do they account for that?

I wonder if the design ever gave any thought to having to reduce the height of the building in the future as the foundation system aged with the mentioned electrolysis issue.

Very informative and i like the fact that you correctly said persian sea.

That's an amazing piece of civil engineering
