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.

Instead, I believe that they should make Transit Oriented Development ( TOD ).

One more reason to not make a giant skyscraper is the sun.

Excellent content. This is exactly the sort of thing I subscribe for. I learned a lot here, cheers Fred and team

[@aftonline]

I would probably build not one tower, but a set of say 6 or 8 slender towers arranged in a circle, interconnected with horizontal sections between them at regular intervals, and a central tower which houses the express lift shaft that goes all the way to the top. The office or residential space would be in the horizontal sections as well as the vertical sections. The entire building would be cross braced for rigidity because of those horizontal sections, which could extend from the outer towers to the centre as well as connecting the towers around the perimeter. The idea is to minimize the vertical loading by restricting each tower to one lift. If your destination is in the top part of the tower you take the central express lift to the closest horizontal level, and then walk horizontally to one of the peripheral lifts to go the rest of the way up. The towers wouldn't be separated by more than about 50 to 100m so your horizontal walk would not be very far.

[@drgeoffangel5422]

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!

[@azeemabdul143]

This comment needs to be pinned....love from an architect ❤

[@tokiomitohsaka7770]

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.

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.

432 park avenue is not 28.5m2,it’s 28m on both sides. So it actually 784m2. Also 28m2 is like two parking spaces.

[@tobik2627]

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.

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.

[@sohovulture87]

'.....you're welcome...' hahahaha! Very interesting indeed. Like this format with engineer and architect hypothesising. Good stuff!

[@fuzzylon]

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.

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

[@ThexBorg]

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.

[@darringreen8630]

What about 5 towers that are 200 floors tall, and then the remainder of the tower extending from a platform on top of that? Distribute the weight evenly between the 5. Yes, there will have to be an elevator (lift) change to reach the top floors, but that can take place on a rain protected vegitation platform, like a park 1km in the sky.

[@koaschten]

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 appreciate that the engineer and architect are conforming to stereotypes in how they look. That's always reassuring.

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?

[@passakornkarnprawatlerdwat5246]

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.

[@andreas.richter]

Yes but the numbers are wrong… 25sqm is 5x5m, which is the length of an SUV (which should be a common us measurement 😉)

[@Samuel_J1]

Yeah, it should be 28.5m each side, which gives 812.25m². For the silly tower it would be 17689m²

[@sebastian85429]

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

[@NSaNelydangerous]

@@Samuel_J1 That makes more sense, it's the length of one side, not a sqm value.

They better install Showers in every Elevator. Plenty of time to take a shower and get yourself ready to go out during the elevator ride from top floor all the way to the bottom! 😏😏

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

[@velisvideos6208]

X shape? Sell it to Musk.

[@Zebra_M]

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.

[@jeremytheimer7443]

The structure shape used by the Jedda tower and the CN tower really does limit space. The CN tower is purely a vanity project, the lower 2/3 of the building only has enough space for an elevator and stairs. The main load is a restaurant and viewing area in the middle. The biggest challenge of building 2km is finding a way to make it profitible.

[@Sanobot]

The numbers for area in the beginning around 03:50 are wrong. What they meant is (28.5m)^2, not 28.5 m^2 and (133m)^2, not 133m^2 respectively.
