Yep, I see forms.

There are floor openings for escalators inside the lobby in the two areas they are forming up so putting up those sections really wont affect access to the building.

OK, that's it ! I'm going to go teach that snow a lesson. The girls and I are off to do some X-country skiing. Oh bugger, I said the four letter word.
Due to the limited number of perimeter columns, the facade of Tower 4 is designed to flex like crazy. The window panel joints, while only 1.5" wide normally, can flex to be over 3" wide.

I got 144'3" at the very top of the parapet, corner to corner, which is chamfered slightly as shown below.

Renders like that and others, make me wonder how the curtainwall panels will be affixed to the building on some of the double-height floors like the observation levels and higher mechanical floors.

Some of those panels look like they are just floating with no underlying beams to attach them to.

^I believe that's where the "steel inserts" come into play in the sectional diagram above.

redux of the above render.

Conde Nast's WTC lease down to 'last drafts'
Signing could come as soon as late this month says Douglas Durst; if it and other pending deals are signed, the 1,776-foot tower would be 85% leased.

The deal for Conde Nast to lease 1 million square feet at One World Trade Center could be signed as early as this month but is more likely to be inked in March, says Douglas Durst, chairman of the Durst Organization, which has an agreement to buy a $100 million stake in the tower at Ground Zero.

“Things are going well,” Mr. Durst said . “”We are getting down to the last drafts of the lease.”

In the meantime, Mr. Durst is heading to China next week to prospect at an economic conference for tenants. So far, the only tenant who has signed a lease for space in the 2.6 million-square-foot tower is China-based Vantone Industrial Co., which is sponsoring the conference that Mr. Durst will be attending. Mr. Durst said Vantone executives told him that among the attendees would be firms interested in leasing space in the tower.

”This is the type of tall tower that will generate interest for Chinese companies,” Mr. Durst said. “It is the kind of building that stands out. It makes a statement.”

Typically, building owners don't make special trips overseas to market their properties. However, there has been international interest in the building for several reasons. At 1,776 feet, One World Trade Center is going to be the city's tallest tower, and it is a symbol of the city's resilience in the aftermath of the September 2001 terror attacks. In addition, the tower is expected to earn a gold Leed rating from the U.S. Green Building Council.


Last year, Tara Stacom, Cushman & Wakefield Inc. vice chairman, and Christopher Ward, the head of the Port Authority of New York & New Jersey, went to Europe to meet prospective tenants. The trip hasn't yielded a tenant, but Ms. Stacom said she is in contact with people she met, and she plans to go back later this year.

“It is an address that is known around the globe,” said Ms. Stacom, who leads the building's leasing team. “International companies are clamoring for information.”

Ms. Stacom said when she heads back overseas, she hopes to have more marketing materials to show than she took the first time. She notes the building still doesn't have an official logo or promotional materials, yet.

Even without materials, the effort has been going very well. Aside from the Conde Nast deal, the Port, which owns the building, and the Dursts are negotiating with two government agencies to take a total of 1 million square feet. If all the deals are signed, the building will be 85% leased.

The deal between the Port and the Dursts should close in the next two months.

Conde Nast's broker, CB Richard Ellis Inc. chief executive officer for the New York Tri-State region Mary Ann Tighe, declined comment.

I'm not sure what effect they're going for, but usually double-height curtain walls have some sort of structure behind them... thin vertical columns on the mullion lines that the curtain panels affix to. If the vertical columns are too obstructing, then you can move them further apart (every 5 or 6 curtain panels) and put in horizontal members to attach the panels to.

I'm not sure what the wind loading on this is, but it's gotta be pretty high 1300 feet above the earth.

Very nice progress. Really nice to see this tower goes up, means so much in so many ways. Can't wait to get back to New York and see it in person. Plus I just love Manhattan.

Though STR's renderings don't show them, there are girts to support the curtain wall every 13' 4".

The steel inserts are to give extra strength to the curtain wall where the wind loads are the highest.

I am re-posting this diagram here in order to convey something that many folks may not understand. The wind is by far the greatest force that this tower has to withstand. All tall buildings like Tower One are called cantilever structures because they are like a beam sticking out into open space, but it is not gravity that they have to overcome, it is the wind.


If you remember from my previous posts this tower is designed to withstand a hurricane. Think 150mph winds.

Is building is sooooooo beautiful and elegant in person.

Drove past it on a gloomy day and it sparkles! Wow!! Can't even imagine how amazing it will look standing at 1,776 ft!

In NYGuys first shot, there will be one day where from that same vantage point the tip of 1WTC won't even be visible.

Breathtaking
