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

[Mr. Lion]

I think this building is going to look best at about 5:00 p.m. in the winter months when the sun is setting and people are still in their offices with the lights on. That way you'll be able to see how many floors it has and it will appear even taller than during the light of day (see newhannibal's photo above for reference).

in my opinion, how a building looks at night is just as important as in day.

[uaarkson]

There isn't much in this world more beautiful to me than the blazing, horizontal streaks of a city's millions of office lights in the dark. This is why the twin towers looked so good at night.

I don't know if the subject was discussed as of yet, but is the tower going to have skylobby's. I think I saw that in one of the blueprint designs.
My point being that, with all the supporting structure outside of the building for getting material to and debris away from the building, shouldn't they be able to use the shafts - or are any of the elevator shafts completed.
I was looking at the start of the glazing on the north-west corner. Anything come lose or debri drop from the exterior stations and .... Well you get the idea.

[Zensteeldude]

There is One Sky lobby on the 64th floor. (Check out page one of this forum, first post, for the floor breakdown of the tower. You will also find links to web cams and such there as well.)

They are using some of the elevator shafts for construction hoists (east side) and there are temporary openings in every floor for 2 sets ( 4 cabs) of internal construction elevators on the west side starting at the 38th floor and up.

Contractors carry insurance for those rare miss-haps.:)

Thanks Zen... I knew someone had the "Inside" scoop. I can tell there's a lot of work going on inside, but you wouldn't know it looking at the pic of the xterior.
I was there a few weeks ago and realized that the N/W crane is mostly used for debris and equipment. Got me to thinking - they must be using the elevator shafts to move material and the like on the inside? And why wouldn't they?
Thanks again. :tup:

I reiterate that is the reason it took so long for these towers to start rising. All that work underground on the "bones".

I've been visiting this site for many years, finally decided to become a part of. Love the pictures, love the discussions, love the renderings. If at all possible can anyone get pictures of the actual erection of steel... it would be a sight to see! Also feel free to shoot questions my way, would love to share knowledge of the ins and outs of structural ironwork. Thanks for having me, and have a great day!!!!

Selling One World Trade Center not an option

http://www.reuters.com/resources/r/?m=02&d=20110125&t=2&i=316732892&w=460&fh=&fw=&ll=&pl=&r=2011-01-25T131458Z_01_BTRE70O10T000_RTROPTP_0_USA-SEPT11

Jan 25, 2011
(Reporting by Joan Gralla and Dan Trotta


New York state and the Port Authority of New York and New Jersey are both grappling with severe financial problems, but selling off One World Trade Center to bail them out would be a mistake, according to Port Authority executive director Christopher Ward.

Both Ward and Janno Lieber, who directs the World Trade Center's rebuilding for developer Larry Silverstein, agreed in interviews that the commercial market was firming.

The Port Authority's One World Trade Center now stands about 56 stories high. Four World Trade Center, one of three towers Silverstein is building, stands 13 stories high.

"People are starting to get excited about moving here as they are starting to see the buildings rise," Lieber said.

"The city's economy is leading the recovery," Lieber said, adding media and financial companies are drawn to the prospect of four modern "green" skyscrapers suitable for their high-tech needs, especially in a city where large office buildings often have to be retrofitted or lack open floor space.

Ward, who was just reappointed by Democratic Governor Andrew Cuomo, said the Port Authority was now confident that it no longer needed New York state to take space in One World Trade Center, partly because the state is too cash-strapped to afford the high rents.

"There may be a long-term decision to bring in less of the state or none at all," Ward said, noting New York now probably pays less than $25 a square foot for its downtown offices.

"We think we can definitely attract a higher-paying commercial tenant," Ward said.

Both the federal government and media giant Conde Nast are still expected to lease space in the complex.

Ward noted that the real estate market was far from as strong as it was when Silverstein signed a long-term lease for the properties just two months before the September 11, 2001 attacks.

"To sell out at the bottom of the market, in the market that we are in right, now would potentially be the worst mistake that we could kind of make," Ward told Reuters.

"The biggest mistake we would make now would be to sell short now -- to think that we could make up either the state's financial difficulties or the Port Authority's," Ward said.

"This has to be an asset that returns value to the Port Authority for years to come," he added.

One World Trade Center, called the Freedom Tower until that name failed to entice tenants, will likely be 85 percent or so rented by 2016 or 2017, Ward said.

The building, whose 1,776-foot (541-meter) height will match the year of U.S. independence, is expected to be finished by late 2013, around four years behind schedule.

Silverstein's Four World Trade Center should open in 2013, followed by Three World Trade Center in late 2014 or early 2015.

When Two World Trade Center is built depends on whether it attracts tenants, but Lieber said: "We are confident there definitely is interest in the marketplace."

Condé to 1 WTC: 'Matter of time'

By STEVE CUOZZO
January 25, 2011

Five months after Condé Nast and the Port Authority signed a non-binding "letter of intent," a completed lease for the glam-magazine factory to move to 1 World Trade Center is inevitable, sources predicted.

The only disagreement is over timing. While several sources believed the epochal inking could occur as early as March, others insisted it would take longer -- "not because anything's gone wrong, but simply because it's so complicated," one said.

Condé Nast is currently at 4 Times Square. Last August, the publisher and the PA announced they had a term sheet. But it was far from a done deal, especially in light of the WTC site's notorious complexities.

However, a final deal for Condé Nast to take 1 million square feet in the 2.6 million square-foot tower's lower half is clearly in sight.

Nobody's breaking out champagne yet. All-but-done deals can and do break down -- as in last year's last-minute scuttling by A&E Networks of plans to move to 150 E. 42nd St.

But the Condé Nast commitment would, at a stroke, make nonsense of widespread skepticism since 9/11 that major companies would ever return to the WTC site.

Condé Nast's stature as a singularly prestigious brand would make all of the site's office space a hot commodity -- at 1 WTC, at Larry Silverstein's fast-rising 4 WTC and in two towers yet to come.

Meanwhile, word that Gov. Cuomo has decided to keep Christopher Ward on as PA executive director is "good news for downtown and good news for the state," said Silverstein Properties' development director Janno Lieber. Downtown Alliance president Liz Berger similarly called it "great news."

Lieber's praise is especially meaningful given the past animosity between Silverstein and the PA -- a history of blame and counter-blame, public name-calling and lawsuits.

Ward, who was appointed to the post by former Gov. Paterson in 2008, reversed a pattern by predecessors who seemed not only ineffectual at getting anything done, but also out of touch with what was going on at ground zero.

On Ward's watch, progress has been remarkable on 1 WTC, the memorial, and the site's fiendishly complicated infrastructure. (When we'll see the Santiago Calatrava-designed transportation "Hub" remains to be seen.)

Ward also pushed through two crucial agreements -- with Silverstein over financing terms for his towers and with the Durst Organization, which will be the PA's minority partner in managing and leasing 1 WTC.

[jigglysquishy]

Can they not do glass in this weather? I only ask because its been almost a month since any glass went up.

[STR]

^They hung the NW corner piece sometime late last week. I expect they'll be filling in that part of the building next.

[Tumbleweed_Tx]

not being anywhere near the site, I'd still guess that they're either waiting for the fireproofing on floors above them to progress, or, they're waiting on another shipment of glass

[meh_cd]

I caught a flatbed with a bunch of glass on the Earthcam on the 20th.

I know some snow is expected in NYC every winter, but this winter it seems like we've (I'm in Philly) been hit more frequently than average. Does anyone know if it has affected schedules at all? Just thinking... some man-hours have to be lost to snow removal or storm prep (tarps?) for each storm. Especially since I imagine they can't use any salt (rust the hell out of the steel).

Thoughts?

Last nights storm put us over 3 feet of snow for January, over 6 feet for the session, so far.

Every long term project has weather delays built into the schedule but this is silly. There may be an "Act of God" clause in some of the contracts.

I bet that just about the only folks working at the site today are Laborers and some Operating Engineers for snow removal.

There are other products that melt snow and ice that are not corrosive.

PS: I didn't even try to go to work today, I don't care how good the AWD system is on my truck. (The weather man gets a D- for predicting 8 to 12 inches, 18+ is more like it.)

basically if not all, most of the answer are now posted (since a looonggg time ago) that are now on the PA website on the Q&A of 1 World Trade Center... I bet most of them don't even know about this forum, except now i know more about the base-concrete placement and that every one who has predicted when the tower is gonna surpassed 7 WTC, reach is final height etc etc... is CORRECT :D

[JSsocal]

Questions Answered: http://www.panynj.gov/wtcprogress/q_a_intro.cfm

In bold are the questions of the spacers in between the glass on the first floor, and as to the waviness of the glass, as well as other cool stuff.

Lynda Tollner is a program director in the World Trade Center Construction Department with design and construction responsibilities for One World Trade Center.

Ms. Tollner has more than 25 years of experience in project management and structural engineering and has worked for the Port Authority for seven years. In the past, she has managed design and construction of a variety of commercial, institutional and transportation facilities including projects at LaGuardia and Newark Liberty International airports and the Port Authority's current headquarters at 225/233 Park Avenue South.

One World Trade Center is scheduled for completion at the end of 2013.

(Note: We received more than 40 questions in response to our "Ask the PA" feature on One World Trade Center. Some of the questions were repetitive, so to avoid redundancy, we eliminated several of them).

Q. When do you anticipate that 1 WTC steel installation will exceed 7 WTC in height? – John, Washington, WA

A. John, we are getting real close. We expect to exceed the height of 7 WTC in February. Right now, we are on the 56th floor.

Q. What do you see as the greatest challenges looking forward toward completion of 1 WTC? – Mike, Moravia, N.Y.

A. We encounter challenges with this project every day and our staff works diligently to meet each and every one of them. Perhaps the greatest challenge we will face in the future is the construction of the 408-foot antenna concurrent with the completion of the roof and the rooftop mechanical systems. Essentially, we will be undertaking two separate projects simultaneously in very limited space.

Q. When do you expect 1 WTC to become the tallest structure downtown, as well as in New York City? Also, why does the first floor of glass skip to every other piece, and finally when will the plaza finishes begin? – Anthony, Commack, N.Y.

A. We anticipate 1 World Trade Center will be the tallest structure downtown by mid-summer when it surpasses the Beekman Tower, and the tallest in the City when it surpasses the Empire State Building by the end of this year. The missing panels of glass on the 20th floor were left out intentionally to accommodate supports for the protection required for the curtain wall glass installation.

Q. When I visited last week, I noticed something strange with the glass. The reflections of things close to the building are very clear, but buildings and objects that are far away seem to be wavy and odd. Is this because the glass has just started to go in? Is there a film on the glass? – George, Philadelphia, PA

A. George, there is no film on the glass. Once the building is fully enclosed and pressurized, the wavy reflection will be reduced.

Q. About what floor will 1 WTC reach by the 9/11/11 anniversary, and what floor will it reach by the end of 2011? – Michael, East Brunswick, N.J.

A. We expect to have steel up to a floor in the mid-80s by the 10th anniversary later this year and near the 104th floor by the end of the year.

Q. There appears to be vents in the façade that cover the large mechanical floors near the top of the building. These mechanical floors and vents also appear to correspond to the original impact site of Flight 11. Is this deliberate or simply a coincidence? – Kyle, Fargo, ND

A. If there is an alignment, as you say, it definitely was not intentional.

Q. How long will it take to reach the 75th floor? – Peter, Verona, N.J.

A. Our goal is to build one floor a week. Given that schedule, we expect to be at the 75th floor in about 22 weeks.

Q. When will the base of 1 WTC by completed in concrete, and how will this process happen? – Zack, Elkton, MD

A. Concrete work at the base of the tower is proceeding, but it must be carefully staged so that it does not interfere with other trades and delivery logistics at the base. Portions of the concrete wall will be done later so that various trades can drive trucks into the lobbies for materials deliveries. For example, all of the elevator rails are being delivered to the North Lobby. Fireproofing materials are delivered to the South Lobby.

Q. Does 1 WTC use the tube-frame structure system like the original Twin Towers? – Benjamin, Canberra, AK

A. No, it does not. 1 WTC involves a building system that consists of a steel frame and a concrete core.

Q. Since the tower is coming closer to being topped out, will there be a topping out ceremony toward the end of the year? – Dominic, Grants, NM

A. We anticipate the tower will be topping out in early 2012. Our focus right now is getting the tower built. When the time comes, we will focus on whatever announcements or ceremony is appropriate. For now, it's just build, build, build.

Q. 1 WTC seems about five floors shorter from street level than the neighboring 7 WTC, which claims a height of 52 floors. Why the difference in height and number of floors? – Josh, New York, N.Y.

A. The number of floors in office buildings does not correspond to a specific height. For example, the first office floor in 1 World Trade Center is the 20th floor, which is approximately 180 feet above street level. However, there are only nine floor slabs between the lobby and the 20th floor, which will accommodate the tower's mechanical systems.

Q. When will the glass façade for the base of 1 WTC be in place? – Tyler, New York, N.Y.

A. Installation of the podium wall glass will begin in early 2012. This work must be staged later to allow the tower's hoists to remain in place, so the podium glass won't be completed until the 2nd quarter of 2013.

Q. I was just wondering when the curtain wall will start on the mechanical floors under the 20th floor? – Spencer, Montreal, N.Y.

A. Just to be clear, the curtain wall and the podium wall glass are not the same. The curtain wall glass is currently being installed from the 20th floor to the top of the building, while the podium wall glass for the bottom 20 floors is in fabrication, with installation to begin in early 2012.

Q. I know that some steel recovered from the site after 9/11 was used to build the U.S.S. New York. Is any of the steel being used to build the new tower? – Joshua, Sparrows Point, MD

A. No. However, there will be two of the massive steel tridents that were part of the original World Trade Center towers on display in the Memorial Pavilion.

Q. When will the spire go on 1 WTC and how long will it take for the spire to be installed? – Logan, New York, N.Y.

A. Installation of the tower's spire will begin in mid 2012, and will take approximately six months to complete.

Q. I noticed a crane on the northwest corner of the building. What will this crane be used for? – Holmdel, N.J.

A. The “slider crane” on the northwest corner of the building is used by the concrete contractor to convey reinforcement and other materials into the building and to remove debris.

Q. How often do shipments of glass arrive at the World Trade Center site? – Erik, Baltimore, MD

A. The curtain wall panels are loaded into shipping containers in Portland, Oregon and shipped by rail to North Jersey, where they are placed on trucks for delivery to the site. We receive one major delivery at the site each week.

Q. Is it true that 1 WTC will top out this year? – Steven, San Diego, CA

A. We expect 1 World Trade Center will top out in early 2012.

Q. I noticed that the crane on the northwest portion of 1 WTC is still attached to the building and no glass panels have been installed on that section of the tower. When will the crane be disassembled in order for the glass to be put up? – Michael, East Brunswick, N.J.

A. As the slider crane moves up the building, the temporary steel on the lower floors is being removed so that the curtain wall installation can continue on this corner.

Q. How many workers are working at 1 World Trade Center at any given time? – Joe, Brooklyn, N.Y.

A. Currently, the total manpower of all of the trades is approximately 1,100 people.

Q. What brand of elevators will be used in 1 World Trade Center? What brand of chillers will be used? – Bob, Louisville, KY

A. Thyssen-Krup will provide 70 elevators and 9 escalators for 1 World Trade Center. There are no chillers in the building. McQuay is providing the self-contained direct expansion air conditioning units on each floor.

[STR]

Kind of cool that building pressurization will alter the glass panes. Makes sense, though it's unintuitive. You just don't expect glass to flex like that, but it does. Makes me wonder if temperature is a factor as well, and that it will "clear up" as things get warmer, since the glass won't be below freezing on both sides ever again.

One more thing I'd have added to this:

The office floors on 1WTC are shorter than the office floors in the other buildings, only 2," but over 80 of them it adds up to half a story.

[Innsertnamehere]

how much you want to bet that some of those questions where asked by people on this website?

They are full of it, do you know how many psi it takes to flex 3 layers of 1/2 inch thick glass ? Two of those layers are laminated ! The distortions we are seeing are not uniform over the width of the pain. no amount of pressurization will remove those distortions.

[STR]

I was thinking more of the temperature difference than anything. Generally, pressurization=heating and other air conditioning, which would cause a minute amount of thermal expansion, not generally noticeable, but since the reflections are caused by a layer that varies by a fraction of a mm, might be enough.

I'm not sure what that would do with a triple-pane insulated window. Are all 3 layers glazed? Might see a bit of difference. If the glazing is applied to only the out layer, I don't think it would, as it's supposed to be insulated.

But I'll defer to you. Either/or really.

[Acer1]

Knowing that the weather is bad for erecting steel, but does anyone know if this allows the concrete crew to 'catch up' a little at least? This way the steel can be put up at a little faster pace than normal once the weather improves, correct?

Yea, that's expansion vs. contraction...not air pressure...? :koko: You ok today Zen?

[meh_cd]

That woman has been wrong in the past, but at least she answers the questions I send in.

[OneWorldTradeCenter]

Wow, didn't expect it would take that long, but it's a huge and massive spire.

So we have to wait until late 2012 until it's really topped out and taller than the tip of the ESB's antenna. It's 1,454ft (443m), a few taller than 1 WTC's roof.

If anything, it will take the concrete just as long, if not longer in this weather. I'm pretty sure it takes concrete longer to cure in cold weather.

Keep up the good work with this awesome photos everyone!!!

Can't wait to see the completed 1 WTC from exactly that perspective, with Beekman in the foreground. It'll be one truly surreal, dreamlike image. Do you suppose reflections of Beekman will be visible in the 1 WTC glass from that vantage point? :banana:

we can only hope....... that is a great vantage point and when 1WTC is completed?:worship: surreal won't do it justice;)

[Zensteeldude]

Yea, that's expansion vs. contraction...not air pressure...? :koko: You ok today Zen?

Cabin Fever !!:crazy:

I'm getting tired of that four letter word that begins with S.

Like the interior of a modern locomotive or a tank, the building will have a slight positive pressure no more than one or two psf above atmospheric though. Like the tank it's for NBC protection.

Now consider wind loads. Even 2 psf pushing out is nothing compared to say 45 psf pushing in. A 130mph wind would produce almost 1.5 tons of pressure on one 5 by 13' 4" panel. (The load would not be uniform across the entire surface of the building and forces on the leeward side could even cause negative pressure, trying to pull the glass out of it's frame.)

Very complex stuff, fluid dynamics.

NBC= Nuclear, Biological, Chemical.

[Zensteeldude]

Notice the thermal break. If it's 4 degrees outside and 70 degrees inside the thermal break keeps the aluminum mullion from being subjected to the two extremes . I'm sure the hot summer sun would produce much greater temperature differences. Also notice that the glass floats inside the frame, to allow for thermal expansion and flexing of the building and glass under wind loads.

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.

When all is said and done this Tower is going to be beautiful !

The X-country skiing had the desired effect, all the girls are taking a nap or a nice hot bath.

So, the "four-letter-word" won again, for now.

Or did it?!?

The top of the columns in the pics above are 4 feet above the 56th floor. Hopefully they can get the 55th and 56th floors framed out before the next snow storm.

This week does not look good for steel erection.

Wow, with the glass so far in the place on the first few floors, it already appears those floors are occupied (according to the pictures shot above). Only time will tell. 2013 is not far. :banana:

[SkyscrapersOfNewYork]

how tall is it?

[Yankee]

Wow, it's going up so quickly. When is it supposed to be topped off, mid-2012? If it continues going at this rate, I don't imagine it taking more than another year tops.

The tower itself was originally slated to be topped out in December 2011, but now they're saying January-February 2012.

7 WTC is barely taller than 1 WTC now. So close!

[Traynor]

^^^UGH! Someone pushed the HDR too far. It ends up looking like a cartoon.

Anyway...The Discovery cams are still down.

:(

I know I am a big conspiracy theorist, but every time they are down, I think it's because they are installing some big piece of Government Spy equipment. and they don't want us seeing what it is.

:D

[RockMont]

The tower itself was originally slated to be topped out in December 2011, but now they're saying January-February 2012.



Can somebody offer a reasonable answer, as to why?

[Roadcruiser1]

Maybe due to the weather conditions. There has been a lot of snow in NYC recently, and it would slow down work on the site. You can't raise steel during a storm.

[RockMont]

That's what I thought. This has been a rather unusual winter there, i know, but during calm phases, progress has been on such a rapid rate, that it is hard to tell how soon or how much more time it will be.

[2-TOWERS]

7 WTC is barely taller than 1 WTC now. So close!

that is the Goldman Sachs Building not #7

[JSsocal]

^^^ 7 WTC = 741 ft
Goldman Sachs = 740 ft

It is very close to passing up both of them

[sw5710]

1 WTC is 670' to the steel splices

[STR]

^^^ 7 WTC = 741 ft
Goldman Sachs = 740 ft

7WTC is 741 to the glass parapet, there's a little half-floor in the middle that goes up to 750 feet. I roughed it out in my re-do of 7WTC's model:

STR your renderings are amazing, the only thing that better then your renderings are the finished product them selves, not even the Port Authority or Libeskind can do a rendering like you do. Out of complete honesty i think this is your calling.


I was wondering if you STR can make a rendering of how it will look like looking outside from the windows of the obervatory deck of tower 1v2 ?Thank You :)

[Islander]

If the largest cross section of the building is 200x200, then the roof will be about 141x141.

[CoolCzech]

They're computer enhanced. Nothing looks like that in real life.

[CoolCzech]

The tower itself was originally slated to be topped out in December 2011, but now they're saying January-February 2012.

And that doesn't include the spire -that will be another 6 months or so. Since the spire is a structural part of the building, it really doesn't make sense to say the FT will be "topped out" without it.

I know the base is 200 x 200 feet...and the roof is smaller , but what is the exact number ?

Actually, the 200 feet often quoted is the column centers. The overall dimension is 205 feet. At the top of the parapet the tower will be 145 feet, overall.

Hummmm, I need to go check that second dimension.

(Even the "half-scale" set of A drawings weighs 78 pounds, no small effort to drag them out of the gun safe and take a look. The full scale set was 5 by 3 feet, came in 3 volumes and weighed over 240 pounds. It was shredded about a year ago.)

OK, I remembered correctly, 145 feet overall at the top.

The building will appear the same width all the way up viewed from north or south. But you'll be looking at the 205 ft side at the bottom and the 205 ft diagonal at the top. So, according to some old Greek guy, the side at the top will be the square root of half of 205 squared, or very close to 145 ft.

New 9/11 Time-Lapse Documentary Debuts at Sundance

February 01, 2011
By Marlon Bishop

The Sundance Film Festival wrapped up this past weekend in Park City, Utah, leaving film bloggers abuzz with predictions about which of the festival's favorites will strike big theatrical deals in the coming year. Though it may not have won the big documentary award given on Saturday, Jim Whitaker's "Rebirth" is likely to be of special note to New Yorkers: it's a new documentary about 9/11 and Ground Zero.

"Rebirth" is more than a film. It's a non-profit organization called the Rebirth Project, which has so far raised funds to enact the Herculean feat of filming a time-lapse video of the entire reconstruction at Ground Zero, shooting one frame every five minutes for 24-hours a day, year in and year out. Whitaker's crew has been gathering footage for the past nine years, and plans to continue filming through 2015.

Whitaker got the idea to do the film about a month after September 11, 2001 when he went to visit Ground Zero for the first time. "I went down there and was looking at the debris and the rubble and I just had this feeling of dread and anxiety," he says. "But also, the sense that one day the place would look very different, and that gave me a sense of hope. I thought, 'How can I capture this feeling?'"

The answer for Whitaker was to set up fourteen specially-designed boxes containing solar-powered 35mm cameras around the Ground Zero site, and document the story of a massive hole in the ground being replaced by a gleaming new Freedom Tower that would stand tall and triumphant.

Although the distribution details haven't been worked out yet, "Rebirth" is expected to be screened on television on September 11, 2011, ten years after the 2001 attacks. A theatrical release is also possibly in the works.

This tower is so elegant and aesthetic, it reminds me of Empire State a bit...
Even now it looks like supertall, I just can't imagine how it will look when it grows tice plus this supermassive ultimate spire.
One of the best skyscrapers ever built.

[HSV Downtown]

I have read, and reread this thread from page one and enjoyed every word. I live in Huntsville, Alabama and visit NYC once a year to see my brother who lives there. This site has been so inspirational to me; it brings tears to my eyes watching this thing rise. Here, I can see all the great pictures you guys post and stay up on all the latest information involving WTC 1 (Freedom Tower to me).

I remember the topic of the trees being planted at the WTC site, but can’t seem to find out how many there will be when all is said and done. Also, what is the significance behind that number? Can someone please give that info?

[STR]

^I believe there's going to be one tree in the memorial for each first responder that died on 9/11. There's going to be 30 to 50 more in the commercial areas, but there's no significance to them beyond looking good.

A crap load of trees by any measure.
