Whoops, I didn't realise that!:bash:
It has now been fixed:cheers:

Most large structures these days that have a basement start off with a massive round hole like that.
Ping An (small hole), Shanghai tower (medium hole, similar to Greenland Centre), Goldin 117 (holy crap HUGE hole!:nuts all had round holes.
The reason is physics. A circle is the best shape for keeping open a large hole. The holes are usually square, notice the heavy duty framework in the corners.
If the circle structures weren't built, then the middles of the sides would likely slump inwards like this:nuts:hno:

Great update! They're progressing well, next steel should be placed soon i think.

What is the purpose of the structures in the last picture?

 

[tinyslam]
