This photo by John Flint shows a contrast between a 3,000 year old Egyptian Obelisk which was given to NY in the 19th Century, and Extell's new "obelisk." Very few New Yorkers are even aware of this obelisk, which sits in Central Park behind the Egyptian wing of the Met.

432 Park will be a new, flat-topped "obelisk".

Central Park will get an incredible skyline. It is good that the new residential megaprojects rise next to it. If I could afford living in a supertall I would definitely want to be as close to some nature as possible

Btw, the 432 Park page loads ok for me

So over the last few days there have been long arguments over roof heights/ actual heights of buildings in nyc forums. Is the 426m to the highest occupied floor or to the roof of this building. Thanks

426m is the roof height. 398m is the floor slab of the top occupied floor, however, there are mech floors above it

I have started the second generation of my roof height diagrams where I hope to follow the construction of 432 Park and 3WTC

Roof height used below:

[IMG]http://i50.************/r70s9z.png[/IMG]

432 Park is now approximately 9 meters or 30 feet tall
3WTC is now approximately 62 meters or 203 feet tall

Seems like a lot of workers are at the sight right now. They also seem to be keeping the sight relatively clean, unlike One World Trade .

Because the site was always perfectly covered with fences so that no one could make good pics from street level, I think today was the perfect day to make pics because the fence was open on the 56th side.

Core rebar is now above street level as well, I recall months ago they said they would be at street level by the end of the year so things are really moving quickly.

I don't like to make predictions about what may happen at 432 Park Avenue as concerns progress (my percentages for being correct with my guesses are maybe 50%!!), as my predictions are based only on observations of the goings-on at the site.

However, I'll make a guess, that perhaps tomorrow, the south section of the current level that has been formed with reinforcement placed, and other appurtenances required, may be poured. I say this, because, I believe all necessary items have been completed as evidenced by the rebar placing crew relocated to placing core rebar, and other areas, and, by viewing the Park Avenue cam, one sees what most likely is an envelope to contain warmth beneath the south section to be poured ( the white sheet placed between the current level and the next lower level). Typically in colder weather such measures are taken to prevent freshly poured concrete from freezing while curing. Space heaters are placed below the formwork to keep the concrete warm, and the protective envelope helps keep the warmth in. Although concrete gives off heat during curing (hydration), the additional protection during cold weather helps prevent freezing, which would be detrimental.

Once again, we shall see.

Where would 2WTC rank on your diagram, if built? Higher than ESB with an approved spire, Or lower without spire.. Seems like all the talk, 2WTC isn't even included anymore,, I would love to see the diamond top out right where ESB antennae starts, then throw a spire on WTC2 to beat ESB.

The tip top of 2WTC is only 20 feet shorter than 1WTC's roof.

I can't tell yet what they are pouring. Is it the floor slab or some column?

2WTC is on hold atm, so I'm not including it in this diagram. It has 387 meters to the roof and 412 meters to the pinnacle, therefore in my diagram it would be between 1WTC and the ESB

I don't know when they started the pour today, but now they have poured the whole floor around the crane. Also there is a new parking spot for the trucks on the 56th side because they build that weeks ago.

im not sure what the plans are for this plaza area after the pour but I would expect this will allow them to stage material and trucks on the site. probably will improve the work flow overall.
