NEW YORK | One World Trade Center | 1,776' Pinnacle / 1,373' Roof | 108 FLOORS - Page 317

^Huh, thanks, I thought I heard a rumor that there was some sort of agreement that the core could only go a certain distance above the floors in NYC.

But, it was a rumor....

The floor decking has to be connected to the steel cage before concrete covers it. They used that same method in the construction of 7 World Trade Center.

I believe that they said that this tower has a moment frame design, i'm not sure if that has anything to do with it though.

Zen,

I now realize the column splices are indicated by the small dark spots - three per column, establishing the four "lifts" you mentioned. What I was looking at and thought were the splice indicators are the small rectangles just above the first row of small dark spots. The green stars are placed below the small rectangles and the red arrow shows where one is "missing". Do you know what these rectangles indicate?

Ahhhhh, that is a missing section profile. Here is an enlarged pic of the area of the print. (edited)

The 13 inside the triangle is just revision 13.

Alright, sorry I didn't get to take photos on Friday or Saturday like I said I would. The weather was pretty bad those two days..but I took some yesterday so here you go..P.S. The lighting wasn't the greatest at the time I went but I managed to get some decent shots.

^^Yeah I know the cab is in the way but this looked better than the second one.

wong21fr · #**6328** Posted **Oct 26, 2009, 3:52 PM**

Nice shots, thanks for taking them.

Looks like the NW plaza pour will happen in the next couple of weeks.

Ghost · #**6329** Posted **Oct 26, 2009, 4:09 PM**

Great update, thank you!

canadate · #**6330** Posted **Oct 27, 2009, 2:49 AM**

Don't know if this has been discussed already ... but has anyone got information about the spire? I know that even the most recent renders I've seen have portrayed an interim design.

Dirty Sandpit · #**6333** Posted **Oct 27, 2009, 9:07 PM**

How many columns are remaining? Have they put them all up yet?

Kieso · #**6334** Posted **Oct 28, 2009, 1:16 AM**

Just done a quick interpretation of this on sketchup, i hadn't quite realised that the tower didn't contain any curves, yet it still manages to maintain a curvy look. It has so many subtle illusions, starting to quite like it

BStyles · #**6335** Posted **Oct 28, 2009, 5:26 PM**

It never stops raining! They'll be lucky to get started on anything by the end of the month!

Raraavis · #**6336** Posted **Oct 28, 2009, 5:56 PM**

Can someone explain why work on the core couldn't be continuing while these exterior columns are put in place?

I think it was mentioned before in the thread. They want to connect the core with the exterior before they pour concrete, so it must be on the same level.

In most concrete core/steel buildings, the core is constructed of rebar/concrete and mounting brackets are poured into place. The exterior steel fits into these brackets after the concrete is sufficiently cured.

In this building, the core is constructed of steel beams/rebar/concrete. The exterior steel bolts into the core steel. This must be done before the concrete of the core is poured.

The concrete of the core cannot rise until all of the horizontal connecting steel for that particular level is installed.

Zen, am I right?

I got a full set from Tishman.

If you want a set all ya have to do is sign this 22 page non-disclosure agreement. (I think I get your car, wife/GF, kids, house and all your bank accounts if you break it)

Next you have to pay 10 cents a square foot to have your set printed. (The prints are 5 by 3 feet and there are about 1,200.)

And last, pay to ship them FedEx certified overnight. (all 340 pounds of em)

I started on a HQ version in Sketchup about 18 months ago but gave up when the files got too big to handle. But I was doing the interior too. (I think the skp file was up to 730megs)
