One tower crane can lift those big columns? How much do the columns weigh?

Carbon fibre only has tensile strength (elasticity) that is greater than iron. It cannot withstand pressure as well as iron (it breaks quicker). It isn't ideal for construction unless a really unique design requires it. Also, it's very expensive.

Carbon Fiber could be used to reinforce concrete in place of steel.

However the extrusion method to create the steel rebar is much much cheaper.

Hello,
so what can we see the metal structure is the inner facade, i mean that artium's frame can't be seen yet? And the floor will be fully made of metal or will it be layed out of concrete on these metal beams?

Hi Little.
Yes the circular beams are the inner wall. The rounded triangular outer wall hasn't been started yet.
They lay corrugated metal on the floor beams then pour concrete on that.
Here is the corrugated metal.



Uploaded with ImageShack.us



So they are laying the beams for the floor of level 10.
The next triple level supercolumn sections are going up.
Looking at the number of columns at the top they could be jumping the form soon.

Morgan Stanley bought a 10% investment stake in the entire building while it was still under construction. The only individually sold floors are at the top of the office zone (57th to 77th floor) and 3 or 4 around the 70th floor have sold for 80,000 rmb a square metre. They're around 256 million rmb a floor, so yeah 40 million USD. Still a lot of space left for sale, but they make you sign a lot of use restrictions in the purchase agreement.

Ray.
Great info Ray! It should probably be pointed out to everyone who is unaware that the trussed mechanical floors (which Fury picture shows quite well) will actually not be round like the main floors but take on a rounded triangular shape like the tower. The cladding will connect to these rounded triangles and create large atriums for the regular round floors. It's very unique! The only almost similar building is The Bow in Calgary, however many of it's "sky-atriums" had to be cut back due to costs. Still a fantastic building of which I'm sure Ray already knows as a fellow Canuck
