They discovered...In the red bubble is an area where the concrete appears suspended. And the shale looks undercut back into the side.
There was a group of men there discussing something close to this area.
It won't really matter in the end since they will all be connected to the same podium to access the amenities., this tower has a smaller plot of land to begin with, but perhaps if it has been give a bigger one the end result would still be the same podium space as now when it connects with the other podiums
If you want to see some awkwardly small footprints for even taller towers I point you to Billionaire's Row in NY a few of those have very tiny lots and the towers are 100m taller.
The reason the first podium is larger is that it has a community centre in its base with a gym and pool and running track, etc etc; it's not a matter of the podium being large enough to support a taller tower… In fact tall towers don't need podiums simply for support purposes. (Toronto prescribes podiums to create urban street walls at ground level while keeping towers separated enough to provide natural light and some views to the units, and to stop wind that races down the sides of buildings from knocking pedestrians off their feet: podium level deflect the wind away.
I would say they are just at the top of P5 and they need to go down to P6. So 1.75 floors to go. If you see on on the west side there is a large area that has plywood that is the loading dock opening for phase 2 on Parking level P2They've excavated so much, but still one more level or so to go.
