Cranes, Formwork etc

G'day from South East Queensland, Australia
A friend in California pointed me here re the Infinity drama. I've not worked on high-rise for 30 years so am rather out of the loop. Back then >100m was tall for Brisbane! I'm now a residential Building Designer specialising in remodelling.
I have a few questions:
  1. Are core walls formed by self-elevating systems similar to the Lubeca system common in the mid-70s?
  2. Is the predominance of hammerheads due to lack of supply of Favco-type cranes or just the sheer footprint of the projects?
  3. @Malec: What software did you use to model the twisting tower?
  4. What mPa concrete do they use & how far away is their aggregate source? The logistics of so much construction in such a small area boggles the mind.
