As has been mentioned ad nauseam, there are concerns about them casting shadows over the park. Is it possible that had these buildings been not only supertall but also significantly wider, they would have had an even harder time getting approved?
All the supertall towers along the 57th Street corridor comply with zoning, so they are as-of-right. This means that they can be built without approvals from the City's Planning Department. 111 West 57th needed Landmarks Commission approval because it is integrated with the landmarked Steinway building. Their form are purely a function of economics and zoning envelope.

Likewise, CPT only need approvals for the cantilever over the landmark next door (Arts Students League). Of the new group of supertall residentials in Midtown, only 53w53 went through the full ULURP (approvals) process. And it suffered for it.

I'm sure that this has been discussed already, but how did they make the tower so skinny without being structurally unsound?

Just caught up on this project and am intrigued.

It has thick concrete walls on the east and west face and there will be a tuned mass damper on the 88th floor, both prevent swaying. It's currently on the 86th floor and 83% up

It's basically a circulation core without any building attached, and the core does most of the work anyway, ask the Rainier Tower in Seattle.

It never ceases to amaze me when I look at it from various vantage points that there are only 40 some odd units in this thing, but that's what you get when all your square footage has to fit inside the core. An amazing amount of work and materials for so few people.

A snapshot in time on the city's skyline. There's someone being born right now, or maybe a year or two ago who will only know the skyline with these towers on it, same as we know the skyline with the Chrysler or the ESB. An image like this will be even more amazing years from now.

Would anyone in the know care to tell me how deep they drilled the rock tendons for this tower’s foundation? The excavation process was obscured to the point I am scratching my head how it works. We never got much of a look at “the pit” like we did for 432 Park.

That seems so long ago, I don't even remember if that was covered here. But no doubt there will be some documentary about the construction of this building as well. Maybe somebody can shed some light on that.

Hard to believe the skyline didn't have these towers on it a few short years ago...

88/91, 1,216 feet tall, 85% to the top

so how will the crown be assembled? piece by piece or like a giant cap? this is going to be wild to watch!

Piece by piece. It certainly will be wild. It should go up quick. There is even a slim chance that during the crown installation, this tower overtakes CPT in height, albeit briefly. :runaway:
