first this fact and the second thing is, off course developers are exeggarating, they will sell their product and make it more attractive on adverts what renders particularly are.

Actually it's not exaggerating at all. That building mistaken for the Princess Tower (Emirates Marina Serviced Apartments) is 254 meters tall, so the Pentominum not counting the spire will be just over twice as tall. When you take into account that it's slightly closer in that render, you discover that it is a perfectly accurate render, and not exaggerated in the least.

Actually it is. Compare it with the 215 m tall tower nearby, and it will make the Pentominium looking like it is at least 600 meters tall ... which is still just a 15% exaggeration.

That project become even more crazy now. So how they've done it ? It seems that piles were i in place all the time. But then, how they were able to dig there ? I supose one posibility is that they pour concrete only to lower parts of piles, and fill higher parts with sand or something neutral for diggers.

I have the feeling that they will continue with this one without putting it temporarly on hold. I am so excited to see, how they will build those "balconies", the roof feature and if they will build an antenna which will be pushed upwards! This project will be after the Burj Dubai is finished, my next favourite project UC!

IMRE many many many thanks for this enourmos update!!!

From my observation of a few hundreds construction sites:

They dig a hole in stages and fill it with a viscose liquid that prevent the sand/earth around the dog hole to collapse into it, and then they dig further adding more liquid in the process. Sometime they also stick metal tubes for the same reason, but only if the piles are not that long.

Once the entire hole (in this case up to 60 meters deep) is dug, they lower inside the metal caissons and pump concrete inside. The pumped concrete being heavier then the liquid, goes straight to the bottom pushing it out of the hole. The liquid is then collected and reused for the other pile. They pump concrete up to the depth they want the pile cap to be so the walls around the rest of the hole on top of the pile cap will collapse once the remaining liquid is pumped out.

Basically: If you want to put 60 meters long piles and the raft would be 10 meters below grade, then you other dig a 10 meters deep hole and face the logistic nightmare of lifting up from there the super heavy pile rigs and crawling cranes once job is done ... or you dig a 70 meter deep hole (well) from the ground level and lower inside 60 meters long (in parts) metal caissons and pump concrete till it reaches 10 meters from the top of the well. Repeat the same for each pile and you're done. Then dug the hole with the much lighter excavators that can be easily lifted up when work is done.

I guess you get the idea.

What i've said in one sentence apart from the fact that it was not necessery to fill higher part with sand. But i've never seen such method before.

It has the potentials to be completed before them if the developer has all the funds needed for s speedy construction process.

Pentominium is now U/C after being "on hold".
I was wondering: there is a direct link with the rush of financial markets last few weeks, and the restart of Pentominium (and others projects in Dubai)?

Sry for my english

It wasn't actually on hold, just speculation that it might be in the future.

Altin well done that is exactly how its done. The liquid is called bentonite and the long pipe to put concrete at the bottom of the pile forcing the bentonite out is called a tremmie pipe

i'm not sure, but the sears isn't considered a spire because it serves a purpose. that's why both patronas towers and taipei 101 were held statuses as world's tallest buildings.


btw, excellent render, addiction. i'm saving that one.
