JEDDAH | Kingdom Tower | 3,303 FT / 1007 M | ON HOLD

[samsonawane08]

Interesting Idea ! Though the idea of a building having height above 1000 metre seems quite far fetched to me if a 828m high tower like the Burj Khalifa ,which
some years back was thought to be quite impossible, can be built there is a
possibility that buildings this tall can also be built. But the problem is Burj Khalifa has a base that covers a wide area(Its a 2,80,000 square meter skyscraper) ,
the base of this building on the other hand looks comparatively narrower and thus I doubt it will be able to support a building that tall. A taller building must also have a wider base. So the design of this building seems quite risky. Yes they have used aileron like fins to counter any problem arising from wind pressure but the problem is the base of the building doesn't seem strong enough to support the load caused by the height of the building.
By the way what technology have they used to build this building.I have heard
slip forming is a very quick and efficient way in building high rise buildings
but is there any new technology that has been introduced lately

You're right, this building will probably just topple over once it gets to a certain height. The designers are probably just guessing how strong it needs to be and hoping for the best.

^^LOL! I'm going to borrow that response when people think they're the very first to consider that we get earthquakes in California and wonder why developers are building tall glass buildings.

it'll probably just tip over on its own no matter how tall because they are building it in the sand.

On a serious note, how far down would they need to go below the sandy surface to reach bedrock?

Contrary to what you might think, the surface isn't that sandy - certainly nothing like the Sahara or other sandy deserts. The geology of the area is mostly depositions of fossiliferous limestone and sandstone, formed when the area was under a shallow sea. A good analogue for Jeddah's geologic condition is Miami, where the compressed coral bedrock (oolite) is rarely more than 6 feet beneath the topsoil.

Edit: The analogy between Miami and Jeddah doesn't expand to Saudi as a whole. Florida is obviously flat, sandy and wet, covered with silt and sand runoff from the eroding Appalachians. The Arabian Peninsula, meanwhile, is arid, rocky and home to terrain both flat and mountainous. Jeddah also sits atop a thin sliver of land known as the Red Sea Rift Basin, formed where the Arabian and African continental plates shift against each other. That means oceanic basalt is somewhere in the mix, but I couldn't tell you where.

I'd normally show image but its way to large.

Hey Fury!
You still around?
You think it passed the 2nd worlds tallest...The World Building in 1890 (94m)?

[kenratboy]

Nice. Certainly past the 'giant hole in the ground' stage.

That is one enormous crane on top.

uh, that's a crane closer in the foreground.


I love this tower, will make a visit in a few years to see it in person when it's done.

[chris08876]

Keep in mind that one reason this is taking a while to rise is the subterranean work. It spans 30 floors underneath.

In terms of engineering, this is a marvel.

Uh there's clearly a huge crane on top of the core as well as tons of other cranes

Kingdom Tower is enormus.Pretty tall in construction so far. Could be 100m by now.

[sakau2007]

I believe they are at the 25th floor now.

Massive shear walls of concrete. Hope there is planning for some light entering the interior!

Burj Kalifa pushed the boundaries of pumping concrete vertically, I wonder where this one will transition from concrete to steel.

No, there isn't. The boom you are referring to is in the foreground, you just can't see it's base.
