Hello,
Google opal tower Sydney.

It is a skyscraper which is cracking. Terrible for the residents.

I have a typical floor plan, but I was hoping some clever soul could rustle up a few more floor plans. The position of the terrace garden move from one floor to others, it's that change i am interested in.

I am just generally interested in engineering stuff and it's an unusual tower with a triangular shape on plan.

Any help is much appreciated.

If not, then, I've just got the kill team commanders book, been away from the hobby for a bit, what are your thoughts on commanders in the game?

They don't know exactly what caused the cracking so far (limited to one apartment, afaik). Engineers are still going over it.

But the 2000 Olympic precinct site is all a reclaimed dump site and former landfill (was used as the dumping ground for a bunch of obsolete power station transformers up until the 70s/80s (pcb leaching into the soil and river was one of the reasons for the "no swimming or fishing" in that part of Parramatta river nearest to it). Settling from that, however, should probably have resulted in more cracking in more apartments.

I'm thinking it is a stiffness problem. The core walls in the centre are not stiff enough to stop the perimeter trying to twist when the wind blows on it.

There are walls at each corner which, usually, would stop any twist but the wall position changes at each roof garden level and the floor slab / parapet at that level has to transfer massive horizontal forces from the shear wall above to the one below. Usually the wall would be top to foundation.

That is consistent with the pattern of damage in the photos, I just see more floor plans to think through it.

Agree about if a foundation fails then more wide spread damage would be expected, I am wondering if this damage has occurred but not presented itself as it is still hidden under plaster board of spandrel panels.
