Quite a lot from memory, but relatively slowly. I had a coffee with one of the structural guys early on in the design who showed me a model and I recall thinking "You'll never get me up there".
This is how they did it.

You guys been up the Gloucester Tree in WA? I started up that one in what was a little bit of wind at ground level. As I got to the top she was moving over a metre each way into the wind and back with gusts. Had to change the undies when I got down!

I spent a bit of my time installing lifts.
When we were building 120 Collins in Melbourne we tried a laser to plumb the shafts but couldn't use it due to the sway of the building especially when a crane took a load.
We went back to conventional plumb lines and learnt very quickly to respect the plumb line integrity . If you broke a line it was a nightmare of tangled wire depending where on the 65 floors you were located.
It was also pretty scary looking down the full length of the shaft. I respected heights shall I say.
