I'm curious what those parallel concrete-looking things embedded in the ground are (last photo above).

Footings for the ground level structure (?) - here is one of the supports the crane is digging up on the far right.

Denzine - good eye - those were just to assemble the large flying forms - here they are after being removed.

Digging for the footings that will sit on the caissons.

I found this slipped in plywood interesting...

The area of the slab around the columns is a high stress area, so maybe the plywood is left on the slab to keep it moist giving a longer cure time. Just a WAG:shrug:

Part of the form that didn't come down easily with the rest - remove when ladder handy ?

Thanks George, can't wait to check the status on this one in person in a few weeks!

A few more...

Updating the figures for this downward. . .

WAS = CHICAGO | 435 N Park | 635 ft | 54 FLOORS

IS = CHICAGO | 435 N Park | 569 ft | 49 FLOORS

. . .

its comical how difficult its becoming in this city to build taller buildings (600ft> )as the standard.. our style of architecture needs to change and get away from the boxy squat designs into the more thinner tapering style.

When did this get shortened? I haven't seen anything on them revising the design or height.

What the fuck. I can't believe this got shortened.

Project rarely get revised to be taller lately. Sign of the time I guess.

This is very disappointing since it is a prime lot in Streeterville. At least David Hovey is ambitious enough to go 60 stories on his next building.

Excellent news for the "Streeterville shelf"

Your tension may vary - note the different sized rebar on the inner and outer faces.

The braided copper is for lightening protection.
