whats the reason for such a floor height difference of a meter or 3.28 feet? I know modern office towers have larger ceilings for wires, air ducts, and such but an extra 3 feet??

They seem to be very fast at building ordinary floor plates, but taking a long time on the truss belt.

Hi all.

The next double level columns are going up fast - levels 23 and 24 I think. I think levels 20 to 22 are behind the climbing form. The top crane supports are at level 18 and the top level we can see below the form is 19.

Levels 20 and 21 are the next belt truss levels with 21 as the next radial truss level. The core of these are done so I expect the succesive double level columns and crane raisings as needed will be happening fairly quickly.

The first belt truss is on levels 6 and 7 with the radial trusses on level 7.
The floor beams of level 9 look near complete and the circular beam of level 10 is in place. Whether or not they lay the floor beams of level 10 next, they will have to add the next sections of the supercolumns before working on level 11.

This project is really moving along.
The outer (rounded triangular) curtainwall may be started when the the steel gets up a few more levels.


Ray.

Truss belts are quite complicated and will hold tons of mechanical equipment, not to mention the trusses themselves. They also differ from the shape of the other floor plates so things take a bit longer. The good news is we'll see things shoot up from here towards the next truss level.

The newer VAV air conditioning takes up more space in the ceiling cavity than the older FCU air conditioning. Newer buildings also often have floors raised up with a cavity above the concrete to run cabling underneath as it's much easier than having to dig channels in the concrete. Higher head room is also much nicer, older buildings usually only have 2.5 metre ceilings which is cramped, 2.7 to 3 metres is much more comfortable

Why don't the Chinese put the number of floor on the core? It would be a lot easier to follow.

I know we are talking offices here, and I'm pretty sure most residential homes in the US have near 3m ceilings, but here in the UK, the average for houses, I would say is about 2.4m, which is what our ground floor has. The first floor has only 7.5ft ceilings. They don't feel low at all. I suppose when you have a very large space, a ceiling of 2.4m would probably feel really low. Ignore my comment, I'm basically thinking out loud.

Most newer residential homes in the US have near 2.7m ceilings (9feet),
and old ones have 2.4m ceilings (8feet).

Man if I had a few mil I'd definitely buy office space near the top. Then I'd put on a suit and pretend to work while actually playing Pokemon on my Nintendo DS

...how much does office space in such a building usually cost, anyways? Does anyone have links to any financial info of that sort? Would be greatly appreciated

It doesn't look like there's going to be much space on each level, the core is taking up so much of it.
