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

well that was fun. go back to discussing the construction of 1WTC please. theres a thing called Private Messaging for those conversations.

[winlinmac001]

Hey, is there any rendering of the Vehicle Security Center (VHC)--for the above-ground portion?

[RoldanTTLB]

There aren't 12 floors of mechanical, though, there are only 6. The numbering then starts at 20 for the actual floors. In an older building, like the one I'm in, a few thousand square feet on every single floor are dedicated to AC and venting and whatnot. In a new skyscraper, none of any given floor is devoted to that, and all of it is centralized onto a few floors. FURTHERMORE, on mildly older skyscrapers, think 50s-80s, the tops of buildings were devoted to mechanical floors. Take One Chase Manhattan Plaza. There are 3-5 mechanical floors on top of the building. The top floors are the most valuable, though, and other than water towers, you wouldn't dedicate the top of a building to mechanical equipment like that. In the case of 1WTC, where security has been made such an issue, this gives you 200 feet from the street to have be a bunker instead of an office building, so that's handy as well. One final note, because 1WTC is so tall, and the core is so large, the lowest floors that are devoted to mechanical are not particularly large as compared to higher floors, so the actual square footage of space committed out of the building is not what it seems.

I'd be curious to see the plans (whoever might have them) of how many mechanical type floors there actually are before floor "20."

(And I'm sorry if they're already posted somewhere on the 481 pages of this thread and I'm just too lazy to spend several hours searching.)

Now THAT ^ is a well thought out and clear answer. Thank you.

Isn't it, though? After all these years, to finally see the main building of the new WTC rising... I can't wait to see it rising above the other buildings from the White Stone.

When is that pedestrian footbridge in that shot slated to be torn down, anyway? Wasn't it supposed to be replaced with a tunnel?

[Innsertnamehere]

yes, but the tunnel isn't finished yet.

also looks like they have a buch of tiles in the pool closest to 1wtc.

That's for a different bridge, the one on the north end (west of the Freedom Tower).

[2-TOWERS]

the foot bridge you see in the background is believe is staying....anyway great updates on WTC #1

[2-TOWERS]

look at the size of the steel beams supports for the path station.....totally HUGE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Oh, they're keeping it as a sort of monument to the way things used to be at the site? I guess that makes sense - I've been visiting the place since I was a small kid, and even remember walking across that bridge with my grandmother (and she departed this world a long time ago). It's nice that some portion of the old state of affairs there will stay untouched.

[OneWorldTradeCenter]

That thing is damn tall right now!

Well, bye-bye Verizon building.

[steveve]

This has probably already been asked before but is it just a trend for a building with a square base to end up with 6/8 sided building, or is it for functional reasons. because its probably not the most ideal for maximizing floor space.
For example 1WTC and SWFC:
