Nice, if you didn't add the extra sky it would have look endless. Btw, it doesn't look that slim.

It looks pretty slim to me. Keep in mind that the bottom of it is near the bottom of the photo... you just can't see it.

Can somebody please tell me what is the purpose of the white coverings on the windows, but they decided to put four rows of windows up without the white coverings .

They're actually blue coverings now. It's probably to prevent scratching or something.

Over the past week or so, Earthcam has been playing with both the 59th St and 53rd St cams, occasionally having them looking downwards at a work platform, and of buildings around Lexington Avenue.

It's time that they raise them to keep up with growing 432 Park Avenue. Yesterday, while they were playing with the cams, I caught this widened view taken from the 53rd St cam.



Then a few minutes later, the cam reverted back to the current view, with the core climbing form now nearly out of view.

My question: how difficult is it to just raise the cams to follow the progress? Come on folks, it couldn't be THAT hard!!

Time flies. I remember watching the Piling work at the end of 2012, when the diggers were on site. This has progressed so fast and well.

I think it's all about appearances. They want the building to look taller than everything else around it so prospective buyers will be impressed. After a couple more floors it will appear taller than One57, so the camera shot will be widened to look like the screen grab you got.

I know this structure has unusually high floors, or at least I think so and I've been trying to look into skyscrapers which have very tall floors but can't find any kind of article or page, anyone have any ideas?

I don't know about such source with that exact info. But I do know some buildings with very high floors.

The floor-to-floor heights are 15 ½ feet with 10-inch-thick slabs, though at the top of the building the slabs are 18 inches thick in order to add more mass to combat acceleration.

In Detail> 432 Park Avenue

How Rafael Vinoly Architects is building Manhattan's second-tallest tower.

http://www.archpaper.com/news/articles.asp?id=7202

Quote:
Topping out at around 1,396 feet, 432 Park Avenue will be the second loftiest building in Manhattan when it is completed late in 2015. It will not hold this title for long. Already there are taller buildings in development, including the 1,550-foot-tall 215 West 57th Street just around the corner. But even once it is surpassed in height, 432 will stand out among the crowd of super-tall residential buildings in New York City by dint of its unconventional and elegant structural system.

In addition to being very tall, 432 is very slim. Its footprint is 94 feet square. This extremely slender height-to-width ratio created several challenges for Rafael Viñoly, whose studio designed the tower with executive architect SLCE and structural engineering firm WSP USA. For one, the wind vortex acting upon such a spindly structure promised to create a very uncomfortable amount of acceleration in the upper reaches of the tower, unless strong measures were taken to brace against it. And then there was the challenge of devising a structure that would not only keep the residents from becoming sea sick and the water from sloshing around in the toilet bowl, but would also provide efficient and flexible floor plates capable of being reconfigured by apartment owners.

The team began by locating the core in the center of the plan and moving the rest of the structure—all reinforced concrete as is typical of residential construction in New York—to the perimeter, leaving clear span bays of 27 feet. The conventional structural solution for managing lateral forces in this type of construction is to use shear walls, which are wider at the bottom of the building and get narrower up the elevation. This, however, did not suit Viñoly’s goal of providing a maximum of flexibility, since it meant that lower floors would have less access to exterior views than those toward the top. Instead, the team came up with a “basket grid” solution of beams and columns based upon a regular, repeating module that would provide the necessary stiffness and the same permeability across the entire structure.

The dimension for the module that the team came up with is 3-foot-8-inch-wide columns and 3-foot-8-inch-wide spandrel beams, leaving six equal open bays across each face of the building—the basket grid. The depth of the columns ranges from 20 inches at the top of the building to as much as 5 feet 4 inches at the bottom. The floor-to-floor heights are 15 ½ feet with 10-inch-thick slabs, though at the top of the building the slabs are 18 inches thick in order to add more mass to combat acceleration

Still more had to be done to relieve the wind vortex acting on the structure. Here Viñoly struck upon a particularly ingenious idea: opening the facade at regular intervals and letting the wind simply pass through. Every 12 floors, two levels of the basket grid modules are left empty. Within these open floors are circular enclosures housing mechanicals that serve the six floors above and the six floors below. Breaking up the mechanicals in this way also meant that the architects could keep the ducting at a minimum, preserving valuable saleable square footage. Two large tuned mass dampers at the top of the tower and outriggers in certain of the mechanical floors further contribute to steadying the building.

At 432 Park Avenue, the structure is the facade. The building was literally designed from the inside out. The basket grid of 14,000 psi white Portland cement, cast around preassembled full-floor cages of #20 rebars with steel formwork, filled in with 10-foot-by-10-foot windows, is left without any fascia. It is as simple and elegant an expression of what makes the building work as one could hope to see in a New York City luxury condominium.

It sounds better if it says: How Rafael Vinoly Architects is building the third-tallest tower in the Western Hemisphere. Or second tallest by roof height in the Western Hemisphere.
