Haha he made as if this guy discovered & burj Khalifa is the 1st using piling & cathodic protection. And the electricity for cathodic protection is not giving any strength
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.
hahaha, You fixed the misconception I had since I was a kid. I spent my whole childhood in my father's shops, selling fishing and boat equipment. We sell these zinc anodes, and I didn't have a clue what they are used for. When I asked my father, he said something like "Maintenance stuff, shut up and get me those ..... " he wasn't mean, just busy working. One client said to me, " to put under the boat ... " I imagined that it might be something to be "consumed" and the take brunt of the force instead of more precious equipment (like the propeller's axis .... ) I Never thought it would oppose corrosion. I feel stupid for thinking that all these years.

@@toxicated3622 That's what challenging projects are about. you need to overcome these geographic restrictions and unevenness to built skyscrapers anywhere you want.
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 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).
Science does not use measuring techniques like "a football throw" or a "small kiwi" because wtf size is small to you? Its really nice to use cutarounds when dealing with non scientific people I guess. The rest of the world just uses metric. But sticks of butter is good to I guess.
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.
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.
All the large Asian dams I studied used ice to cool concrete to dissipate heat of reaction as the concrete set. Even in the middle of winter, pouring concrete for railway piers on permafrost need ice, again to dissipate heat so as not to damage the permafrost.
Zinc or aluminium anodes are used in salt water, magnesium anodes are used in fresh water. The anodes must always run parallel to the length of hull. Zineti, S.A.
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
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 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
For 3. Concrete is also porous. So even with concrete cover, or even hydrophobic concrete the reinforcement bars are still going to corrode over time. Cathodic action is commonly used in offshore structures.
@@WalkDK I would think adamantium is much more expensive than steel. they would rather just add on a cathodic action system and it would still be cheaper.
The tower was constructed by Samsung C&T from South Korea, which also did work on the Petronas Twin Towers and Taipei 101. Samsung C&T built the tower in a joint venture with BESIX from Belgium and Arabtec from the UAE. Turner was the project manager on the main construction contract
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.
that’s with everything. Science is the testing of a predicted outcome. For it to evolve into a theory it has to work 3.5 million times successful for every 1 failure (sigma 5). Usually the mistakes in engineering were human error, not an unknown force.

let's be honest, it's not a great idea to build a skycraper in a desert with no hard stratum, frankly the design/engineers brought this on themselves, just like when americans build their cardboard houses next to fast moving rivers and complain when the land erodes and their house gets sucked into it and complain about the forces of nature, just don't build there?

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.
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.
Every building made out of concrete has a lifespan. The buildings are torn down and new buildings are made in their place when that time comes. The foundation just has to hold it there for that much time, nothing more nothing less.
@@akay4086 good point. But I dont think recycling the Burj Khalifa will be worth the effort. There are many buildings from the last many centuries that are still around, way past their lifespan as it is way better to maintain them instead of recycling them. That's how we come to today's town centers of almost any city. I think we should be considering that instead of counting on dismantling those enormous buildings in 80 years or so
@@mazocco It just cant last for centuries.Concrete has its own limitations, repairs can only make sure it reaches its lifespan. A building on such a scale has to remain in very good condition to remain standing and once the concrete starts to reach its limit it will just become a disaster waiting to happen if its not torn down. The concrete buildings cant be compared to the older stone building in terms of their life expectancy.A stone can last for so much longer than a slab of concrete. Its just that modern concrete make structure like this possible whereas stones cannot.
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.
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 ✋
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 😊
06:21 "now the answer you've all been waiting for", I forgot what the video was about at that point, because wow, that is an insane foundation 😲 Great video!
Investing is considered a bedrock in making generational wealth. Most people don't know when, where or what to invest in. Fortunately, great investors of the past and present can provide us with guidance and ideas. Meaningful contributions are always welcomed.
@@rodiyahyusuff7702 Yes, you're right, it's not watching all videos wasting time on strategies, I was ignorant doing so till I met Sir Lucas S.Chamberlain last year at a startup funding event in Washington DC.
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!
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. 😝
Congratulations! An outward foundation would go a long way towards longevity. Ships have a practical limit of 400m. Buildings sort of 100 floors to stay within proven experiences. Anybody can bend the law of physics as long as they can run or hide.
It makes no sense for Dubai to build such tall building simply because they have plenty of space. But they can't go for the biggest dick award if they just build out.
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
Given that the system needs 24x7 electricity to withstand the corrosion resistance, I dont think it is a very sustainable structure. Not only that, but even with electircal corrosion resistance, if small corrosion happens, it is still susceptible to failure and it is going to be tough to reinforce the foundations. They can probably generate the electricity needed from solar farm reserves but still as an ongoing system it is not looking good.
@@lqlaliut897 it's not the most sustainable but it doesn't have to be No its not. That's extremely rare to happen let alone for that to cause failure It's looking good so far

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.
Building Integrity has a great video series on the Millennium Tower, from what I understand it seems like they were assuming to get subsidies for bedrock support but didn't and had to go with their other sketchy cheaper design to not lose face. They put so many friction pylons so close together that they started to lose a lot of their functionality.
@@roevhaal578 In addition to putting the piles too close together (which captures the soil and loses much of the friction), the foundation was also designed for a lighter steel frame building but it ended up trying to support a heavier concrete one.
You know what they say about foundations built on sand. It's inevitable. Needing electricity to keep it standing is absurd and it should've never been built.
@@trutharrow5311 even copper that carries the electricity rusts. It turns green. Nothing is 100%. Time were corrode away the foundation. That salt water will corrode the electrical wires that is supposed to protect the foundation. But you are right. The engineers were paid millions, and those dumb Arabs were suckers for it.
@@trutharrow5311 And one more thing to add to my earlier comment that the Arabs were suckers. Those engineers might have been paid millions, but they forgot to install a sewer system in the building. The building's poop has to be hauled away by trucks everyday. So much for your engineers.
Wach Tom scott's vidéo about some river flood prévention system in London, they apply the same technique to prevent corrosion, and it's a more vital infrastructure than a skyscraper that must never fail.
I think ppl haven’t seen Dubai enough I lived in Dubai for 20 years before finally coming back to home country i.e India And one thing I have noticed is that not only that Dubai is filthy rich but also they have got everything covered They have plans for sustainability after oil runs out They plan on being fully electric by just a few more years They have built many things that suggest this theory They have solar panels that are actually powering a whole building made by DEWA ( Dubai electricity and water authority) that’s also the company I use to work in. Even tho India is my home country I still admire Dubai’s extensive planning and execution of their goals for future I would want India to learn from them and do the same ❤❤❤ Dubai is technically ahead by atleast 5-10 years In Terms of thoughts about future Every country should do this
To save costs initially during the 2008 recession era. Besides, dubai is building 6 billion usd swerage system to be ready by 2025 under its sustainable city plans.
They do not have sewerage pipelines flowing underneath the city. But they have sewerage system that does not empty in the water bodies, but turn desert into fertile land.
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.
im sure that Mr Bill Baker carefully considered what advice Mr Bill Baker would offer in regards to all the experience that Mr Bill Baker might provide to Mr Bill Baker
@@hindugoat2302 That's a good point but it has to be asked if the Burj Khalifa an exceptional building design or are other large buildings in that area built with similar foundation strategies. If it is exceptional then the design may be untested in the long term. In fact they may have already factored in a life span. Like 100 years or such.
The secret to its foundation are actually the lack of proper plumbing in the building. The lack of proper poop processing means more space for foundation support
This is not factual, it was only at the early stage of delivery of the building as it was delivered as one of the first building of the Master Plan prior to securing the funding from sale of other towers, thus before the district infrastructure was ready. There has been sewage installed there for over a decade, in fact the fountains are made from the tower’s recycled water it’s a system by Hitachi. th-cam.com/video/cxat_5ch3uQ/w-d-xo.html
Cool feat of engineering, but what an incredible waste of resources. Also, is there any way they can measure corrosion/embrittlement on the rebar? The cathodic protection method seems quite novel, cool, but not very tried and tested.

amazing how much work and effort has been put into this building!
Great explanation, really interesting. Funding the maintenance will be what breaks this building.
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 ✋
شكرا على المعلومات 👍🏻💯
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 😊
The tower may have been a product of oil-rich ambitions, but you can't deny that it is an engineering marvel.
It has a septic tank
Engineering marvel for the fact that all ingineers working in Dubai are not Arabs.
how is it a marvel when theres shit tons of trucks moving feces everyday, theres no proper plumbing
@@StefClaessen Yes if you spent your life learning about the world from youtube 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Yes .. But Dubai is Oil poor !!!!!
It will topple over one day.
Awesome video! Thanks for using the metric system 😊
not all the time :(
Projects like this show the brilliance of the human mind
06:21 "now the answer you've all been waiting for", I forgot what the video was about at that point, because wow, that is an insane foundation 😲 Great video!

@@rodiyahyusuff7702 Yes, you're right, it's not watching all videos wasting time on strategies, I was ignorant doing so till I met Sir Lucas S.Chamberlain last year at a startup funding event in Washington DC.
He had some interesting things to say about the state of algorithmic trading today, obviously I'm seeing results, and my trading is going smoothly.
Trading is like a real time business if you want to win it, you need to be prepare for it. Markets are unpredictable, and you can't predict every.
Thanks 🙏 for making my day with engineering vids😌
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!
Thanks to this video, I realized how vulnerable the building is.
Bro these videos be mad interesting,ain’t gon lie engineering ain’t easy
Good explanation sir.
Watching from Bangladesh 🇧🇩
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. 😝
Yet somehow against all odds, that building is still standing lol
Congratulations! An outward foundation would go a long way towards longevity. Ships have a practical limit of 400m. Buildings sort of 100 floors to stay within proven experiences. Anybody can bend the law of physics as long as they can run or hide.
It makes no sense for Dubai to build such tall building simply because they have plenty of space. But they can't go for the biggest dick award if they just build out.
naaaaah we could just throw a few million rocks underneath and poured concrete to make our own bedrock
@@excelsior8682 Too soon to tell.
thank you very much for all your amazing informative videos! :)
Thanks for a well put video with education.
I am definitely sharing this with my friends when I get back
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
It probably will not stand the test of time.
Given that the system needs 24x7 electricity to withstand the corrosion resistance, I dont think it is a very sustainable structure. Not only that, but even with electircal corrosion resistance, if small corrosion happens, it is still susceptible to failure and it is going to be tough to reinforce the foundations. They can probably generate the electricity needed from solar farm reserves but still as an ongoing system it is not looking good.
@@malithaw it will
@@lqlaliut897 it's not the most sustainable but it doesn't have to be
No its not. That's extremely rare to happen let alone for that to cause failure
It's looking good so far
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?
These strategies are quite rigorous for the regular. As a matter of fact, they are mostly successfully carried out by pros who have had a great deal of skillset.
That's impressive! I could really use the expertise of this advisor, my portfolio has been stagnant.... Who's the person guiding you?
my financial advisor is
*JACKSON STEN MARSH* I found him on a CNBC interview where he was featured Afterwards I reached out to him. he has since then provided me with entry and exit points in securities I focus on
Thanks for this tip. His website popped up on Google immediately I searched him up. I read him resume and it seems pretty. I wrote him and I’m waiting on him reply.

Extraordinary engineering, insanely inspiring!!
What a dangerous building ?
This channel really educates me about so many things I was curious about , This is what I was looking for!
All I learned is that it is a horrible idea to build a tall tower next to the beach.
No its not
@@eventusvantos1905 how many other towers are built by the beach?
Burj Khalifa is not close to the beach lol.
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.
The engineers called for over 30 pilings under the Millennium and some cheap ass cut it down to 18. Insane incompetent and corrupt.
So you mean to tell me the world's tallest skyscraper is just nailed down to the earth
Haha, they all are technically 🤣
So are most oil rigs, My mate used to do that for a living.
You always impress me with your animaitons 💯
Very strong video, thanks!
So good :) thoughtful design + accurate animation
Too bad the designers of the Millennium Tower didn't watch this video first!!! :)
😂😂
Building Integrity has a great video series on the Millennium Tower, from what I understand it seems like they were assuming to get subsidies for bedrock support but didn't and had to go with their other sketchy cheaper design to not lose face. They put so many friction pylons so close together that they started to lose a lot of their functionality.
@@roevhaal578 In addition to putting the piles too close together (which captures the soil and loses much of the friction), the foundation was also designed for a lighter steel frame building but it ended up trying to support a heavier concrete one.
You know what they say about foundations built on sand. It's inevitable. Needing electricity to keep it standing is absurd and it should've never been built.
Those engineers were paid millions. They know way more than your sorry little a§ my friend. Thanks for your salty comment tho
@@trutharrow5311 even copper that carries the electricity rusts. It turns green. Nothing is 100%. Time were corrode away the foundation. That salt water will corrode the electrical wires that is supposed to protect the foundation. But you are right. The engineers were paid millions, and those dumb Arabs were suckers for it.
@@trutharrow5311 And one more thing to add to my earlier comment that the Arabs were suckers. Those engineers might have been paid millions, but they forgot to install a sewer system in the building. The building's poop has to be hauled away by trucks everyday. So much for your engineers.
@@henripan9584 jealous much? You should do something else other than worrying about these rich af arabs. Maybe find a job at McDonald's?
Wach Tom scott's vidéo about some river flood prévention system in London, they apply the same technique to prevent corrosion, and it's a more vital infrastructure than a skyscraper that must never fail.
I think ppl haven’t seen Dubai enough
I lived in Dubai for 20 years before finally coming back to home country i.e India
And one thing I have noticed is that not only that Dubai is filthy rich but also they have got everything covered
They have plans for sustainability after oil runs out
They plan on being fully electric by just a few more years
They have built many things that suggest this theory
They have solar panels that are actually powering a whole building made by DEWA ( Dubai electricity and water authority) that’s also the company I use to work in.
Even tho India is my home country I still admire Dubai’s extensive planning and execution of their goals for future
I would want India to learn from them and do the same ❤❤❤
Dubai is technically ahead by atleast 5-10 years In Terms of thoughts about future
Every country should do this
Dubai loves you back
Thank you for your kind words
The song touches my heart, it makes me cry. but really i love it so much. And it makes me feel happy.
Also I love all the songs
Okay but why isn't the Burj Khalifa connected to the sewer system?🤔
To save costs initially during the 2008 recession era. Besides, dubai is building 6 billion usd swerage system to be ready by 2025 under its sustainable city plans.
It is
It is... Via truck :)
It makes you question priorities, doesn't it?
because, overall, that country is still in the middle ages
Dubai already has a sewer system, that's old news u are telling
World: Wow! Who built this city?
American Engineering: You're welcome Dubia.
People of Dubai are smart. They hire best builders in the world! 🇺🇲
nonsense

Does this mean that hydrogen gas bubbles up from the cathode, and what about reactive corrosive sodium?
So fine it does not connect to a sewer system.
Burj khalifa doesn't have a sewage pipe. All toilet waste goes in truck
yeah for all that money they could have built a pipe pumped sewage system there
It does connect to a sewage system quit spewing lies
They do not have sewerage pipelines flowing underneath the city.
But they have sewerage system that does not empty in the water bodies, but turn desert into fertile land.
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.
im sure that Mr Bill Baker carefully considered what advice Mr Bill Baker would offer in regards to all the experience that Mr Bill Baker might provide to Mr Bill Baker
Dubai will be abandoned as soon as there is no need for fossil fuel.
no building has its height reduced over time.
the foundations need to take into account decay and weakening over time
@@hindugoat2302 That's a good point but it has to be asked if the Burj Khalifa an exceptional building design or are other large buildings in that area built with similar foundation strategies. If it is exceptional then the design may be untested in the long term. In fact they may have already factored in a life span. Like 100 years or such.
@@kmg501 tallest in the world - that title is what they are aiming for
that buys a lot of prestige property value
Fascinating!

The secret to its foundation are actually the lack of proper plumbing in the building. The lack of proper poop processing means more space for foundation support
Yes, I've read that all their sewage has to be trucked away daily.
This is not factual, it was only at the early stage of delivery of the building as it was delivered as one of the first building of the Master Plan prior to securing the funding from sale of other towers, thus before the district infrastructure was ready. There has been sewage installed there for over a decade, in fact the fountains are made from the tower’s recycled water it’s a system by Hitachi.

What glue did they use for burj khalifa foundation elmers .?
Cool feat of engineering, but what an incredible waste of resources.
Also, is there any way they can measure corrosion/embrittlement on the rebar? The cathodic protection method seems quite novel, cool, but not very tried and tested.
They're too rich. Don't worry about them bro
Cathodic protection has been in use for at least 200 years and is found on every large structure
props to the cameraman for building burj khalifa again to show us how its done
I love that you managed to show it toppling over about ten times
Maybe repetitious animated image works like a voodoo curse.
Ok. Now talk about the sewage system 🤣🤣🤣
😂😂😂
😅😅
They don’t have one I think
Fascinating....🤔🤔🤔
In a few words
With so many things that could go wrong
THEY WILL ⏰️
Great work Lesics ,,, 🙏🙏
Damn, this is not just a building, it's straight up one of humanity's biggest engineering triumphs.
