Hi B1M, Please note that at 3:27 you have written 28.5m ^2 foot print which must be typo and should be the length of the side of the square footprint. Or else thats smaller then the average home footprint in even the UK.

You have a mistake in the video - at around 3:25, you state that the building's footprint is 28.5 m², but that would mean that each side of the building is just a little over 5 meters long. That wouldn't fit even a bathroom, obviously. 🙂 According to Wikipedia, floor plates are squares with 28 m sides, that means that the footprint is about 784 m².

They said the same things about building simple buildings back then. I'm no engineer but I imagine a building like that will need to be a core within a core within a core and every 100 floors or so should be able to shift in any direction to kind of compensate for it swinging
3:26 On-Screen "28.5m²". *WRONG !!* That would be 5.34m x 5.34m = 28.5m², or about the size of two parking spaces. That tower is skinny, but it ain't that skinny.

As a retired mechanical engineer, here's my thoughts on a structure that is so high, and thus so massive. I am not a civil engineer, but I would have thought that for such a structure to be built, it would need a foundation, at least a quarter of the total height, below the surface, perhaps even equal to a third of the total height. That would mean digging a huge hole down into the bedrock, which in itself could be a huge engineering structure. Of course, the building could be stablised like tall radio masks with " guy" rods coming down from the structure from various heights, and that would mean that the foundations, would not need to be so deep. The biggest problem for any structure so tall, is the mass, and thus the compressive stress at the foundations. One could envisigage a structure, that has cast iron at the foundations, up to a certain level, then steel, then an aluminium monocoque structure, there on up to the top. For stability, the width to height ratio has to be just right, and thus the foundations would have to cover a huge area, akin to the Effiel Tower. Maybe, they just scale up the Effiel tower design, with material adjustments for mass and stress, because that structure, has done pretty well so far. Can it be done, yes of course, when money, and sense is no object! But whoever designs it, will need to know what they are doing, especially when it comes to identifying all the possible loading conditions. Once it is built, the real practical problems start, like emergency staircases, you walk a freakin 2Km down, or up, if the lifts dont work!
You’d probably need to switch to exotic materials like carbon fiber for the higher parts especially. Maybe even some high compressive strength ceramic materials like porcelain being added to the concrete in the foundation to make it handle the insane compressive loads, and keep holes for cables to keep tension across the different internal parts of the building so it won’t topple by wind. Also make ceiling height for each floor higher to reduce the number of floors and thus reduce the weight and occupancy. Also, unlike current skyscrapers with their counterweights dealing with wind, such a tall structure would likely experience low frequency standing wave oscillations from the wind and would require multiple pendulums to counter the motion for the peaks of the wave where constructive superposition would occur. Either way, this is a Richard measuring contest rather than practical. Still interesting from an engineering perspective.
@@deadmxss roads are the only place in the UK which hasn’t converted to SI. This is an engineering video and engineering is exclusive done in SI in the UK. And I’ve lived in the UK for the past 9 years, I work in engineering and the only place I see imperial units are roads or people height/weight.
03:47 I don't quite understand 133 m2, is 11,5×11,5 meters. If the average city block is 80 meters wide, that should be more than enough. I'm not sure that the units of measurement are ok.
The two guys said it correctly. What that extrapolation gives you is a building with a footprint of 133m x 133m. The video editor just incorrectly „transformed“ that into 133m2.
Yeah I think the structural engineer went above his skillset trying to calculate a surface area. Hope he's not the one who was contracted to build the house I live in.
@@Nounooonneither of them are structural engineers, but Arup have the best engineers in the world. Clearly the video editor has misunderstood what they said.
Actually there is a good reason. Oil states want to bring in other business to create a service based economy. That can be self sufficient, but you need a reason to start moving there. Projects like this are supposed to kill two birds with one stone: loads of services move to the city to complete the project, and they stay because there's all this great stuff around. In theory. But I don't have any better ideas other than going back to camels when the oil runs out.
3:28 There's a pretty big mistake there. 432 Park Ave isn't 28m² (28 square meters), it's 28m squared - thats over 700m². Same for the proposed tower - that would come out to over 17000m² with 133m sides.
Really interesting and technical (but easy to consume) video to watch - seeing whether the design could work conceptually at a high level and key challenges that would be faced. More like this Fred!
The notion of a 2km building calls to mind the huge mega-buildings depicted in Blade Runner (1982). I wonder how feasible it would be to build such a structure with a large, wide base, rather than as thin as possible.
It would be like Neom, but square. :) Too expensive to build. It could use more material than a couple of Three Gorges Dams and some 20 years of construction.
What I want to see is a 2km tall building that's also 2km wide and is an entirely self contained city. Just a massive cube in the middle of the desert.
The King of All is preparing a 1,500 mile cube city (with new physics) that will come down to a new earth in His good time! Only those of the faith of Abraham will see that city though.
@@llook Pyramid building was proposed a few decades back for Tokyo. It was envisioned to be 4 km high. The project was not even considered seriously because a) no construction materials could bear such load b) not enough oxygen on higher levels,
432 Park Avenue footprint is not 28.5m2! Each side is 28.5m long, so it is 28.5m x 28.5m = 812.25m2. Still very slim for such a high building, but it definitely is not 28.5m2 shown at 3:27. Same applies to a suggested footprint of the 2 km high building. I assume is side would be 133m long, thus the footprint would be 133m x 133m = 17689m2 and not 133m2 shown at 3:52.
You can see the look on the other guys face when that happens. This was not a great video in my opinion. Why would we want to see them tracing and drawing images that are out of proportion 😂
Few architects look to tripods. They work great. Large floors could be spanning between the three legs to form parks. Like Eifeltower has 4 legs. With the leaning-in legs, elevators could even be simply vertical cables like orbital elevators proposed. Bypassing the structure, supoorted from above, very lightweight and efficient way to do it. When building the 2000 meter tripod, from the first cantilevered park, you have the support needed to be stable.
I think there needs to be a follow up video - Experts explain why certain rulers, governments, etc. feel a need to build a tallest building just for the sake of being tall - when there's no practical need for it nor for the accomodation and facilities such a building brings.
This was awesome guys. You guys already put out insanely high quality content....but this was perfect. Its always nice to hear professionals in the field giving their opinion on the feasibility and possibilities of projects around the world. Always gives us a very unique point of view of the challenges and techniques. Also having a bit of a sneak peak into how some great minds would go about getting something like this built.

Chances are you're quite late to the party, the idea is to get in early on blue chips before it becomes public. There are lots of life changing opportunities in the market, and maximize it.
I designed a hypertall in 15 minutes using an X shape and 9 interconnected skyscrapers starting from lower thinner ones on the edges and then increasing the height by 100% and the width by 30%. Two rows of them x4 wings excluding the central and most robust tower in the middle. There are two interconnections (30% of the total height, then 60% and the tower in the middle is maximum elevation. I'm really drunk but i've been designing skyscrapers for fun since 2000, lol. It's an accurate 3D sketch but i can't really show it cause youtube sux
I designed one too, by skipping the first 1.98 kilometers I was able to drastically simplify the design. Getting it up there and making it stay there without anything underneath will be a challenge, but I'll leave that up to the construction teams to figure out.
@@jamesogden7756 hey not to crack wise or anything but you might be onto something there. Imagine if they spread that shit all over the desert instead. LUSH
6:51 this is an easy problem to solve just have 1 fast lift which stops at every 25 the floor and then have another lot of lifts which go from every floor between 0 - 25 or 25 - 50 etc that way you only have 2 shafts which can take the same as 20 lift shafts

We need a series on how skyscraper / building is built from start to finish. I want to see the differences between architects and engineers and who exactly designs what etc.
the footpring of 432 park avenue is 28.5 m² ? thats 5 x 5 meters? and the upscaled version with 133m² is 11 x 11m. some things wrong. one side of the square with 28,5/133m is what was meant i guess.
Great video, as usual! The funny bit was hearing ARUP's engineer ( Vini ) talking about the potential use of wind turbines in order to generate power... in split-screen with some stock footage of the Strata tower in London, with its wind turbines turned off ( forevah )
Fascinating engineering. I’ve been in Jeddah, that building is horrifying and it’s sucks. I would not like to spend any time in a 2km building like this
7:30 cable elevators won't cut it in a 2000 m high rise building. No word about about options like the Thyssen Krupp "vertical magnetic levitation elevator" which they call "MULTI" ? Bonus, it can not only move vertically but also horizontally, so you have a vertical shaft and when you reach your level you take the exit to a parking position and leave the cabin. Bsically dozens of autonomous cabins zipping though the building. They go at a targeted speed of 6m/s sp 2000m in about 5min 30sec, but passengers will have access to a cabin every 15 to 30 seconds.
I wish someone would suggest the Prince to build a skyscraper to the moon, to really show of the Arabia superiority. I mean why settle with the Line horizontally, when you can have a VERTICALLY line?!
How about completing: Oxacon, Sindalah, The Line, Trojena, Leyja, Epicon, Siranna, Utamo, Norlana, Aquellum, Zardun, Xaynor, Elenan, Gidori, Treyam, Jeddah Tower, Qiddiya and the Dragon Ball Theme Park before announcing a 2km skyscraper???
Wind sheer is the biggest challenge, but don't forget the thinning atmosphere above 1km. There may be some air pressure differentials above 1000 metres. It could be on a rotating base and shaped like a fin and the tower rotates based on wind direction. If fixed, the basement would need to be about 1/4 -> 1/3 the height.
I don't understand the footprint at the beginning at 03:25. It says 432 has a 28.5m² footprint. That's a studio apartment. I don't understand how it goes on to say the 2km building has a 133m² footprint either. What are these figures supposed to mean?
432m tall building has 28.5sq.m. footprints so 2km building, which is about 4 times as tall, should at least have 4 times bigger footprint. The point is that the footprint would be stupidly big for a super tall building.

Quite the best video you've given us this year, thank you. No doubt a great insight and explanation of behind the scenes considerations engineers are faced with when architects come a-knocking on their door, for those of us who fancy that we know a thing or two already, it was an interesting reminder and led to so many more questions. Was there no room to mention the latest in pre-booking lift journeys; effects of gravity on pumps getting water that high; even the benefits of cylindrical towers with those wind blades spiralling up them? And and and? Please can you consider a part two going into such details.
Because they are talking about pushing boundaries and because no-one is forcing us to watch, we could just turn the page, but we are still curious, I think...
That's a second time I've heard of Arup at this channel. Seems like some hi-skilled engineering company and the guys here are really explaining stuff pretty nice. Would be great if you'd do a video about that company.
Oddly enough, they don't mention simply making the base of the building huge. That would work fine - a 1km diameter building on the base should be easily enough foundation to build 2km high. Ofc the cost would be massive - you are effectively building a mountain, but it would relatively simple to design and build in concept, and definitely strong enough.
I agree that any building that tall is going to need to rewrite the rules regarding looks. I don't think it can be a tall, slender tower like we are used to--at least not without some significant material breakthroughs.

Once it is built, the real practical problems start, like emergency staircases, you walk a freakin 2Km down, or up, if the lifts dont work!
This comment needs to be pinned....love from an architect ❤
You’d probably need to switch to exotic materials like carbon fiber for the higher parts especially. Maybe even some high compressive strength ceramic materials like porcelain being added to the concrete in the foundation to make it handle the insane compressive loads, and keep holes for cables to keep tension across the different internal parts of the building so it won’t topple by wind. Also make ceiling height for each floor higher to reduce the number of floors and thus reduce the weight and occupancy.
Also, unlike current skyscrapers with their counterweights dealing with wind, such a tall structure would likely experience low frequency standing wave oscillations from the wind and would require multiple pendulums to counter the motion for the peaks of the wave where constructive superposition would occur.
Either way, this is a Richard measuring contest rather than practical. Still interesting from an engineering perspective.
Excellent content. This is exactly the sort of thing I subscribe for. I learned a lot here, cheers Fred and team

Having those two experts explaining this stuff was really interesting, nice video!
I just wanna thank everyone in making this video for using the SI units

03:47 I don't quite understand 133 m2, is 11,5×11,5 meters. If the average city block is 80 meters wide, that should be more than enough. I'm not sure that the units of measurement are ok.
I guess they meant 133 * 133 m2 and 28.5 * 28.5 m2
So: 17689m2 and 812m2
The two guys said it correctly. What that extrapolation gives you is a building with a footprint of 133m x 133m. The video editor just incorrectly „transformed“ that into 133m2.
28.5m2 should have been 28.5x28.5 m^2, the 2000 meter tower was 133mx133m. They messed it up :)
Yeah I think the structural engineer went above his skillset trying to calculate a surface area. Hope he's not the one who was contracted to build the house I live in.
@@Nounooonneither of them are structural engineers, but Arup have the best engineers in the world. Clearly the video editor has misunderstood what they said.

Actually there is a good reason.
Oil states want to bring in other business to create a service based economy. That can be self sufficient, but you need a reason to start moving there. Projects like this are supposed to kill two birds with one stone: loads of services move to the city to complete the project, and they stay because there's all this great stuff around.
In theory.
But I don't have any better ideas other than going back to camels when the oil runs out.
Tower of Babel itself couldn't be infinitely high to reach God since the ancient builders will lack of oxygen.
3:28 There's a pretty big mistake there.
432 Park Ave isn't 28m² (28 square meters), it's 28m squared - thats over 700m².
Same for the proposed tower - that would come out to over 17000m² with 133m sides.
Really interesting and technical (but easy to consume) video to watch - seeing whether the design could work conceptually at a high level and key challenges that would be faced. More like this Fred!
The real question is not how.
The real question is Why?

The area measurements in the beginning of the video are wrong.

I’ve been noticing lots of mistakes in their videos recently
Yeah, 3:53 … puny two bedroom apartment has a footprint of 60 m²
28.5m2 should have been 28.5x28.5 m^2, the 2000 meter tower was 133mx133m. They messed it up :)

Given that KSA has scaled back The Line to about 2% of its original length, I’m not holding my breath for groundbreaking of a 2km skyscraper
Always a good day when there is a new B1M video!
"There are other ways to keep something tall and thin upright"
That's what she said
What are you saying? The tower should be covered in blue-coloured glass, and called Burj Viagra? 😂
I was going to say something like "Now you have my attention."
😂😂😂😂😂😂😂
@@citibear57 👏🏻🤣
The notion of a 2km building calls to mind the huge mega-buildings depicted in Blade Runner (1982). I wonder how feasible it would be to build such a structure with a large, wide base, rather than as thin as possible.
Good idea.
It would be like Neom, but square. :) Too expensive to build. It could use more material than a couple of Three Gorges Dams and some 20 years of construction.
Now I want them to build it just so I can look at a facade full giant commercial with an Asian woman drinking Coca Cola...
Notice the were pyramid design, not skinny pencils
I'm not sure concrete and steel could support that
432 park avenue is not 28.5m2,it’s 28m on both sides. So it actually 784m2. Also 28m2 is like two parking spaces.
current height of Jeddah tower is 252 m from planed 1000m+. They just about build a quarter KM tower and they already talking about building a 2KM one
What are they compensating for?
Idk
The failure of the line.
Probably the fact they havent finished the Jeddah tower yet.
trying to distract us from all the human rights violations that take place there
They have 0 women in decision making positions and it shows. If you only have fat old men smoking hooka making decisions, that's the result.
What I want to see is a 2km tall building that's also 2km wide and is an entirely self contained city. Just a massive cube in the middle of the desert.
The King of All is preparing a 1,500 mile cube city (with new physics) that will come down to a new earth in His good time! Only those of the faith of Abraham will see that city though.
@@slaveofjesus3878 I bet MBS thinks you're referring to him.
Or a pyramid!
@@dw5s was thinking the same thing
@@llook Pyramid building was proposed a few decades back for Tokyo. It was envisioned to be 4 km high. The project was not even considered seriously because a) no construction materials could bear such load b) not enough oxygen on higher levels,
432 Park Avenue footprint is not 28.5m2! Each side is 28.5m long, so it is 28.5m x 28.5m = 812.25m2. Still very slim for such a high building, but it definitely is not 28.5m2 shown at 3:27. Same applies to a suggested footprint of the 2 km high building. I assume is side would be 133m long, thus the footprint would be 133m x 133m = 17689m2 and not 133m2 shown at 3:52.
Came here looking for this comment. 28m2 is basically the size of a standard living room; would have thought they’d know a bit better.
thought as much, such a mistake is quite embarrassing for a channel promoting engineering
You can see the look on the other guys face when that happens. This was not a great video in my opinion. Why would we want to see them tracing and drawing images that are out of proportion 😂
Different kind of B1M video, but I really like it. I hope we get more like it
Few architects look to tripods. They work great. Large floors could be spanning between the three legs to form parks. Like Eifeltower has 4 legs. With the leaning-in legs, elevators could even be simply vertical cables like orbital elevators proposed. Bypassing the structure, supoorted from above, very lightweight and efficient way to do it. When building the 2000 meter tripod, from the first cantilevered park, you have the support needed to be stable.

I really liked this format of video! Hopefully it does well, I look forward to more
I love the way they are trying to be incredibly polite just in case they win a contract for work in the middle east...
I think there needs to be a follow up video - Experts explain why certain rulers, governments, etc. feel a need to build a tallest building just for the sake of being tall - when there's no practical need for it nor for the accomodation and facilities such a building brings.
I brings investment and diversifies the economy. Its that simple.
they are building a lot of stuff besides the big cold projects that get attenton.
They usually go more into context of video topics on their podcast
This was awesome guys. You guys already put out insanely high quality content....but this was perfect. Its always nice to hear professionals in the field giving their opinion on the feasibility and possibilities of projects around the world. Always gives us a very unique point of view of the challenges and techniques. Also having a bit of a sneak peak into how some great minds would go about getting something like this built. Really unique and fascinating work. Would love to see more of these two and/or others sprinkled in every now and then on new and proposed infrastructure and projects. Im not a very smart person so I love hearing people a lot smarter than me dumb it down and simplify it. Either way, I love hearing people who know a bunch about their field and love what they do. It really shows, and it always fascinates me. Keep up the awesome work!

You know most of said land is worthless wasteland. Like, you spend time outside it's so bad.
why not
I designed a hypertall in 15 minutes using an X shape and 9 interconnected skyscrapers starting from lower thinner ones on the edges and then increasing the height by 100% and the width by 30%. Two rows of them x4 wings excluding the central and most robust tower in the middle. There are two interconnections (30% of the total height, then 60% and the tower in the middle is maximum elevation. I'm really drunk but i've been designing skyscrapers for fun since 2000, lol. It's an accurate 3D sketch but i can't really show it cause youtube sux
X shape? Sell it to Musk.
I designed one too, by skipping the first 1.98 kilometers I was able to drastically simplify the design. Getting it up there and making it stay there without anything underneath will be a challenge, but I'll leave that up to the construction teams to figure out.
So essentially using 1000 year old flying buttress technology. Good idea.

6:51 this is an easy problem to solve just have 1 fast lift which stops at every 25 the floor and then have another lot of lifts which go from every floor between 0 - 25 or 25 - 50 etc that way you only have 2 shafts which can take the same as 20 lift shafts
one of my fav channels. more videos with construction guys and architects drawing and teaching!

the footpring of 432 park avenue is 28.5 m² ? thats 5 x 5 meters? and the upscaled version with 133m² is 11 x 11m. some things wrong. one side of the square with 28,5/133m is what was meant i guess.

Fascinating engineering.
I’ve been in Jeddah, that building is horrifying and it’s sucks. I would not like to spend any time in a 2km building like this
7:30
cable elevators won't cut it in a 2000 m high rise building. No word about about options like the Thyssen Krupp "vertical magnetic levitation elevator" which they call "MULTI" ? Bonus, it can not only move vertically but also horizontally, so you have a vertical shaft and when you reach your level you take the exit to a parking position and leave the cabin. Bsically dozens of autonomous cabins zipping though the building. They go at a targeted speed of 6m/s sp 2000m in about 5min 30sec, but passengers will have access to a cabin every 15 to 30 seconds.
Ahh... a Turbolift.
I wish someone would suggest the Prince to build a skyscraper to the moon, to really show of the Arabia superiority. I mean why settle with the Line horizontally, when you can have a VERTICALLY line?!
How about completing: Oxacon, Sindalah, The Line, Trojena, Leyja, Epicon, Siranna, Utamo, Norlana, Aquellum, Zardun, Xaynor, Elenan, Gidori, Treyam, Jeddah Tower, Qiddiya and the Dragon Ball Theme Park before announcing a 2km skyscraper???
As I practised commercial architect for 20-years, I agree with everything the two gentlemen said
Wind sheer is the biggest challenge, but don't forget the thinning atmosphere above 1km. There may be some air pressure differentials above 1000 metres.
It could be on a rotating base and shaped like a fin and the tower rotates based on wind direction.
If fixed, the basement would need to be about 1/4 -> 1/3 the height.
I don't understand the footprint at the beginning at 03:25. It says 432 has a 28.5m² footprint. That's a studio apartment. I don't understand how it goes on to say the 2km building has a 133m² footprint either. What are these figures supposed to mean?
432m tall building has 28.5sq.m. footprints so 2km building, which is about 4 times as tall, should at least have 4 times bigger footprint. The point is that the footprint would be stupidly big for a super tall building.
Yes but the numbers are wrong… 25sqm is 5x5m, which is the length of an SUV (which should be a common us measurement 😉)
Yeah, it should be 28.5m each side, which gives 812.25m². For the silly tower it would be 17689m²
they mean (28,5m)².... 28 meter squareD. understandebly this is very different from 28 square meter... i guess some writer/editor got this mixed up
@@Samuel_J1 That makes more sense, it's the length of one side, not a sqm value.
Nothing to explain because it will never work. just like NEOM, the line the palm islands etc etc.
Actually everything that has been made in Dubai works : Palm Jumeirah, Burj al-Arab, Burj Khalifah

As a fan of Adam Something, I expected my viewing experience to just be me laughing and/or shouting about stupid giant ego-projects.
But I was VERY pleasantly surprised to see these guys taking a real crack at "what if" - some of their concepts actually look pretty interesting. Hopefully we'll see them implemented in a (much smaller) building that actually gets built.
Got some good world-building ideas for my spec-fiction work too, so thankyou! Have a sub!
Quite the best video you've given us this year, thank you.
No doubt a great insight and explanation of behind the scenes considerations engineers are faced with when architects come a-knocking on their door, for those of us who fancy that we know a thing or two already, it was an interesting reminder and led to so many more questions.
Was there no room to mention the latest in pre-booking lift journeys; effects of gravity on pumps getting water that high; even the benefits of cylindrical towers with those wind blades spiralling up them?

That's a second time I've heard of Arup at this channel. Seems like some hi-skilled engineering company and the guys here are really explaining stuff pretty nice. Would be great if you'd do a video about that company.
Oddly enough, they don't mention simply making the base of the building huge. That would work fine - a 1km diameter building on the base should be easily enough foundation to build 2km high. Ofc the cost would be massive - you are effectively building a mountain, but it would relatively simple to design and build in concept, and definitely strong enough.
Great work , I wouldn't be surprised if they did use some of your ideas. Great episode.
I agree that any building that tall is going to need to rewrite the rules regarding looks. I don't think it can be a tall, slender tower like we are used to--at least not without some significant material breakthroughs.
