Westside Story:

Another jump and the HINES sign is looking directly into our family room. We should be able to read the computer monitors when the office floors are full of workers :p

The lower section shows additional steelwork and some corrugated sheeting similar to that used on the roof of the elevated park over the train tracks. They appear to be leaving the southwest corner (lower left) next to Bay St, as a work and storage area for supplies coming in and being prepared for a lift

A closer look at the steelwork and corrugated sheeting. There are three separate floors being worked on at this time, the top layer is at the same level as the roof/floor of the elevated park

Eastside Story: (same zoom as the previous pictures)

A lot of formwork has been taking place for the level 02 bus depot floor, you may be able to see the curve of the ramp that will service departing buses from the 02 level to street level. Just as an observation the westbound Gardiner is mostly slow going most of the day, it gets better later in the evening but the eastbound Gardiner is almost always open, freewheeling, high speed unblocked travel.

A Closer look at the east side formwork of level 02 bus depot. In the lower right you may be able to see the carpentry skills required to form conical shapes created from plywood that will top-out the concrete pillars that will eventually be supporting this floor. They've done this to all the of concrete pillars in this area

What are those steel posts around the elevator core for? And why is it taking so long for the main structure to rise?

The 'steel posts' are the structure of the actual building and they ARE the main structure (or part of it). The floors will be supported by and go out from them. Frankly, this project is moving at record speed so I am not sure why you seem to think it's 'taking so long'.

Got another community update email with a short presentation in it today that I thought people might be interested in. They're targeting curtain wall installation to start in Q1 2019 - really excited to see how the glass will start matching up with the renders.

Nice little representation of the elevated park-fronting food hall, in that deck:

I knew that they were per se but only a minuscule part of it, but the main bulk has not risen above ground level. An elevator core rising so much first to such a degree is not typical in highrise construction in Toronto.

Makes complete sense to me.

Certainly, it's pretty normal for a concrete core and steel frame building. The trades are normally separated by a distance in height - mainly for access reasons I guess. If you're used to looking at all concrete residential towers, then yes the pattern is different as the concrete structure and concrete core are all tied together, get poured at the same time etc. For commercial towers think of it as a series of trade waves 'rippling' up the tower.

Regarding the 'main bulk' not rising, again, I suspect the clue is in the differing construction methods being used. The concrete slabs for the bus terminal are post-tensioned according to the update posted above, and you can see the tendons being laid out on site for this. This is a method of making concrete slabs span larger distances without increasing their thickness, but takes time to do. You wouldn't want the tower having to 'wait' for this. As this is to the side of the tower however, it would seem entirely sensible to launch the tower concrete core, get the tower steel chasing it (followed in time by the flooring, then the cladding), and once both are clear, start on the post-tensioned slab. All three can then proceed alongside each other without one waiting on the others.
 
Though we are still waiting for the City and Waterfront Toronto come up with (or announce) final (??) recommendations about the Queen's Quay East LRT and how it will get to Union Station, there is a connection (in every sense) with CIBC Square as they had to turn over the western section of one (or more?) of their basement levels for a new transit stop. Presumably that space is now sitting there 'waiting' for a transit decision as to how (or if) this space will be used. Something to keep our eye on once the new Council starts getting staff reports.
 
That space was visible while they were pouring the basement. There's a long tunnel along the western edge of the basement
 
Why do some Toronto office towers use steel frame and others use precast concrete? Surely one method is better than the other, however uilderscand developers define better.
