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

Purely design related, not all of them going up have followed that trend either. Check the IFC and ICC in Hong Kong. The floor space is not really compromised much however, they are still extremely large buildings.

Not sure if you're keeping track, but 1WTC starts as an 8 sided building, tightens to a square, then finishes as a square. The whole time it also maintains 4 vertical faces, which do maximize floor area. It's meant to evoke the original twins without actually running ground to roof with 4 sharp lines.

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.

Excellent post, just 2 corrections, there are 11 floors of mechanical spaces and every office floor has at least one fan room. (See prints above)

Dear Members

I would just like to apologize for my part in Wednesday nights fiasco.

I well not let one member deprive this forum of my knowledge and experience.

I would also like to apologize to the mod who had to clean up the mess ( I assume it was NYGuy). I well try to be more tolerant in the future.

Chris

I would think they well have too. Otherwise the corners are going to be way to far away to offer any protection.

Why does it says 1,551 feet to the top of floor 100? Is the height measured from the lowest floor below grade level?

The PA uses an elevation system with the zero point being 300 feet below mean high tide at Battery Park Point.

The Lobby is at elevation 311' 2" or 11' 2" above mean high tide at Battery Park Point. (Subtract 311' 2" from any elevation shown on the prints.)

Try getting that info from another source !

Cool. I learned something today.

[Zensteeldude]

I am willing and able to answer any question I can.

Having so many tunnels in it's domain and the PA not liking negative numbers in it's elevation system they adopted the 300' below system. For example, the lowest point in the Lincoln Tunnel is 236'.

to Zen.

Pictures from today up later tonight or tomorrow... depending when I can upload them without my brother whining that I slow the internet connection while uploading.

[Zensteeldude]

Cool Dude, looking forward !!!. I would kiss you but, you're really not my type !

[NYCLuver]

Haha just my usual generic photos that I have done of 1WTC yet again.

[Zensteeldude]

Hey, you are going to win back that "Steel Porn Photographer " award, just a matter of time !

Play it out tonight with Joe Jackson One More Time. ( I well personally hunt down and tickle to death anyone who calls this the Taco Hell song.)

I am very appreciative of your informative posts. i am not at all versed in any thing that has to do with architecture or construction so i am learning a lot from all of you. Having been a skyscraper and bridge fanatic since i was about six, i most likely missed my calling. when others were drawing whatever when i was young, i drew skylines with a suspension bridge thrown in for good measure so, finding this forum to read and learn about my favorite city and all the new construction going on has been a lot of fun, thanks to you all!

I love all of the new green space around the WTC.

I bet Zen has a "A clean desk is a sign of a sick mind" plaque somewhere in that mess.
