The support for them anyways - the supercolumns are much narrower - and each will be supported by around 4 of these (except for the two along Bloor)

From this afternoon...
Creating a level bottom...
the 'great leveller'...at the SW notch.
Some close quarters for hefty equipment...and a blue water tank? (facing to the NE)....
Hefty 'drill bits'...

Why would they lay fill or aggregate when they are about to drill holes for the columns? Thoughts?

Connection to the PATH?

Path connection wouldn't be down at this level - it's likely to allow a steady safe base for the drilling platform to work. It's a Ministry of Labour requirement.

They will lay a bed of aggregate and compact it this will serve as platform for the crane and the caisson drill to move on.
due to their size and wight the equipment will sink and possibly topple if they are on native soil.

What makes these super columns so super? Also, are we taking the exoskeleton support columns here?

Because they are so large and only 8 of them. Yes, they are the exoskeleton ones.
Yes they are large
