Love it.

Gotta get it done today. Tomorrow and Saturday will likely be lost to a big storm that is coming.

STORM WARNING: NYC is expected to get dumped on tomorrow, at first with rain and then later a blizzard. Don't expect to see anything other than a white screen on the cams.

Wow, what a change when I just looked at the cam. Now already nearly done with the floor pour.

Looks much better now.

That's pretty much a requirement, given that they are poured from the placement boom that's mounted on the core.

this part of the floor was not poured by the looks of it. No rebar either.

I find it interesting how quickly after concrete is poured I see people walking on it.

How soon can you go on freshly poured concrete without messing it up? I always thought that you couldn't walk on freshly poured sidewalks for a while - but maybe that is cheaper slower drying concrete?

Hope this helps.
I dont have much knowledge in construction, can someone explain what this means?

I am sure someone might be able to better answer but i would think once the core gets to around 6-7 stories we will start to see things normalize in regards to X amount of days per floor.

When people can walk on it, it has not the strength yet for another floor on it.

It will get significantly faster when they are building the regular residential floors.

432_CORE_CLOSEUP

So i happened to grab this closeup of the core, and for the life of me I cannot see anything protruding or any plugs that might be removed to reveal rebar in the core. The west side of the core looks completely smooth.

Are either of these mechanisms described installed and I just can see them?

If so, would someone point them out?
Thanks

What a busy day at 432 Park Avenue. Today, the floor slab was poured. On the Park Avenue (east) side, the stainless steel forms are currently being jumped up to the next level, and the core is also rising.

The workers were feeling ambitious today. That is tough to do when it is below freezing all day long.

Walked by the site a couple hours ago - snapped a few shots with my cell phone:

The three concrete pieces on the left give a sense of what the exterior will look like - the one in the middle has pretty much lost all of its blue tint at this point...even on a gloomy day like this, it looks pretty damn WHITE. On a sunny day, this tower is going to be blinding. I'm starting to think those of you who have been predicting this to be a real beauty when it's done may be on to something...


The building on the left in this pic (the Four Seasons hotel) is 682 feeet tall...when 432 Park reaches this height, it won't even be half way to the top -when it passes the one on the right (the Franklin National Bank bldg), it will still have over 1000 feet to go. This thing is going to be astonishing.


And....here's a Lomma truck delivering a bunch of....ummm.......really big pencils? Anyone know what thiese things might be?

Nice pics.
As for the bars, I don't think they are for underneath a floor laying horizontal. I think they are for temporary support helping the columns.

I love the four seasons. Thanks for the shot up and the update! Next 2 days I'll use the cams to see the NYC blizzard conditions.
