^Bumping this to thank you for the answer to what both Mr Saturn64 (IIRC) and I were asking.
But it doesn't seem to answer why the technique hasn't been used
far more often here in NYC.
Is it cost, generally speaking?
One more note:
IMO, the dual-tower planning used quite often in Calgary is indeed reflected in this project; but most likely not by necessity.
There, however, it
is, IIRC because it's more feasible overall rather than to have just one hella tall tower.
The up-side (albeit for Calgary and other towns that follow this model) is density.
The old expression "more bang for the buck" goes both ways.
