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".

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.
