Me too amigo! Another 400m+ tower for New York! And it's already U/C.

Re: Nordstrom: apparently the height is still not final and could be well above 1,522'.

The city is on fire!

How tall can NYC's skyscrapers go?

As towers surpass 1,400 feet, one structural engineer predicts 2,000-foot spires are around the corner—and maybe even half-mile-tall spires will follow suit.

Quote:
The growing list of super-tall, ultra-skinny towers—reaching higher than 1,400 feet—has raised the question of just how far New York City developers will dare venture into the sky.

Although it may be difficult to predict what materials and engineering advances will permit, one structural engineer who has worked on several soaring buildings, including 220 Central Park South and a spire planned at the site of the Park Lane Hotel, said it won't be long before 2,000 feet or even a half-mile high will be possible.

According to Stephen DeSimone, who operates his own firm, DeSimone Consulting Engineers, cement and steel have doubled in strength in the past 10 years and already make structures up to 2,000 feet possible. Mr. DeSimone expects those materials to become 50% stronger in the next five to 10 years, allowing developers to build even higher structures with less bulk.

"The whole point of going high is to have big windows to enjoy the view," Mr. DeSimone said. "If you have thick concrete supports and structural elements everywhere, it impedes that. But that's changing."

The last major roadblock to building upward has been creating sophisticated dampening mechanisms to reduce the natural sway that gigantic towers experience from wind.

"People who buy $90 million penthouse apartments don't want to feel like they're in a boat," Mr. DeSimone said. "Right now, engineers and builders are exploring the idea of advanced dampening systems that will anticipate the motion of a building and counteract it before it even sways. This is the last hurdle in building taller than we are already."

New buildings like 432 Park Ave. use an internal pendulum—a gigantic pile of steel plates hung on cables inside the top of the tower—to stabilize the building during gusts of wind. As the tower moves, the pendulum stays put and counteracts the shifting. The building at 220 Central Park South, which is even more pencil-like than the 1,400-foot tall 432 Park Ave., has a 1,000-ton dampening pendulum on its unoccupied top floors, according to Mr. DeSimone.

But those systems are reactive, Mr. DeSimone said: They resist movement once it happens, but don't anticipate it with sensors that detect wind and building sway in time to offset it. Towers that soar even higher than those properties will need such technology because structural movement becomes more pronounced at extreme heights of 2,000 feet and beyond.

"Systems are being developed where a building's interior pendulum can be controlled to move ahead of time," Mr. DeSimone said.
I say it's about damn time NYC gets its first 2,000 footer!

Still a vision though.

Its nice to see the affect that the JC supertall will have on the skyline. Complements Lower Manhattan nicely. From certain angles, JC looks like its fused with Lower giving the effect of a massive, bulky skyline. Quite dramatic coming on the Goethals Bridge.

Seems like just yesterday the total completed was in the 50s. Now it's in the 80s, and proposals alone have hit 50.

I know right? Since last year, the 200m+ count really took off! And now all the supertalls are coming online. Only Shenzhen can rival New York, which has 71 buildings completed and U/C, respectively. Could be a bit more, since CTBUH is not that accurate on Chinese buildings. But most 200m+ buildings are well covered.

EDIT: I forgot Dubai: 82 buildings over 200m completed and U/C, respectively.

Most of these proposals will happen too. Its nuts. Not just for supertalls, but everything below it.

What to look forward too:

Pardon my ignorance, but in the renderings posted by Hudson, what's the building between 15 Penn and 432?

I think thats the supposed SHoP tower for the MSG area. Although it might be a matter of perspective from that angle (+/- 5 blocks). If I had a closer look at the area, and could see the adress, I'd be able to tell you.

Thanks for the info. Once the Hudson Yards and the WTC get built out, and East Midtown rezoning gets going, I imagine that'll be the next district to see a truly radical transformation.

YIMBY reports that 56 Leonard (821ft/250m) has topped out! --> http://www.yimbynews.com/2015/07/con...-tops-out.html

50 West (783ft/239m) has about 6 floors left + parapet and hence should top out next. And then 5 Beekman (687ft/209m).
