The rebuilding schedule at the World Trade Center site is once again up in the air.

Arbitrators have given the Port Authority, which owns the land, and developer Larry Silverstein 45 days to renegotiate a construction timetable.

The decision was handed down after Silverstein sought damages and rent abatement for infrastructure delays.

The arbitration panel denied those requests, but relaxed a provision which would have stripped Silverstein Properties of development rights to Towers 2, 3 and 4 if they are not completed on time.

In statements, both sides had a positive reaction to the panel's order to head back to the negotiation table.

WTC developer Larry Silverstein denied $3.5B Port Authority payoff for Ground Zero delays

Developer Larry Silverstein was slapped down Wednesday in his bid to snag $3.5 billion in penalties from the Port Authority because of building delays at Ground Zero.

An impartial panel of construction experts nixed Silverstein's demand to pocket $788 million in rent relief and shut the door on his bid for $2.7 billion in future damages.

Silverstein had argued the PA's failure to build the Transportation Hub, Vehicular Security Center and other key structures at the World Trade Center site crippled his ability to finance and market three towers along Church St.

Claiming he was entitled to 10 years of free rent - plus a fat payday for damages - Silverstein took the case to arbitration in August, blaming the PA for blowing its obligations under a 2006 Master Development Agreement.

The three-member panel shot him down.

"We are not persuaded by [his] claim that the PA acted in bad faith and thereby breached the agreement," the ruling said.

The panel said Silverstein failed to show the PA's "action or inaction" at Ground Zero delayed construction of his WTC towers.

Gov. Paterson quickly applauded the ruling, calling it "the most responsible approach to rebuilding at the WTC site - to move the project forward in a way that protects the public's resources."

Moving to end the bitter and costly battle over the sacred site, the panel gave the agency and the builder 45 days to develop a new set of schedules to rebuild Ground Zero - or else.

If the feuding parties fail to come to terms, the panel said it would dictate how the 16 acres are rebuilt.

New timetables and funding schemes could also mean new delays at the troubled site and an uncertain fate for some key buildings.

"I'm ready to work with the PA 2-4/7 to hammer out a deal assuring that the World Trade Center is fully rebuilt as quickly as possible," Silverstein said.

"One thing is clear from the ruling," Mayor Bloomberg said in a statement. "There is a deal to be made."

A more in depth article regarding the arbitration situation.

From the Downtown Express,
"W.T.C. decision sends sides back to the table

By Josh Rogers

Both sides claimed qualified victory in the World Trade Center dispute after an arbitration panel ruled Tuesday on some issues, but ordered the parties to negotiate a new rebuilding schedule in 45 days.

W.T.C. developer Larry Silverstein, who was asking for a few billion dollars in damages from the Port Authority for numerous violations of their 2006 Master Development Agreement (M.D.A.), received no money Tuesday, but the panel voided the provision that would have awarded the development rights to the three most viable tower sites back to the Port if the buildings are not completed in 2013 — which is virtually impossible at this point.

The confidential, 22-page decision obtained by Downtown Express first came to light in a Crain’s article Wednesday afternoon, prompting each side to quickly release statements praising it."

It's St. Paul's Chapel. There's also graves at Trinity Church nearby at the end of Wall Street.

The graveyard shot is very cool...almost looks like the headstones are "watching" the building go up. Could also be one of the most expensive graveyards in the world, if the land were priced at its true value per sq foot!

I understand that this is not a webcam complaint forum, it is about the construction of 1WTC. HOWEVER, as I enjoy watching the daily progress of the site, I have to say that as THE MOST IMPORTANT CONSTRUCTION SITE IN THE UNITED STATES OF AMERICA, these should be the best, most reliable web cams in the country.

Someone please fix the HD cam (PER MAN ANT LEE), and then walk over to the RGZ cam and put a black velvet blanket around it to CUT THE GLARE!

Rant over

oh! my god! i love the freedom tower,
i must go there when it is finished.

It´s growing up fast! :banana:

I was just in Lower Manhattan, walked around the site, thing is huge already

My favorite tower ..........

Hello, I'm from Argentina and wanted to know who has the WTC steel structure that can withstand fire and other things that can cause people undue and It would begin with the first story "usable"

Im sorry, i dont quite understand that question... any chance you could re word it to help us answer it?

It sounded like:
What extra protection do the office floors of 1WTC have against terrorist attacks/disasters?

Im sorry, i dont quite understand that question... any chance you could re word it to help us answer it?

I think he's asking whether this new tower can withstand heat from a huge fire. If so it would be better than the previous towers which buckled. Also if it could withstand other disasters.

The answer is that it depends on the structure of the tower. The previous one had trusses which proved to be inadequate as the floors broke off from the core at the point of the bolts and then fell down upon each other, building up the weight on the floors below. Stress increased on the outer wall due to the buckled floors being angled down and a depletion of structure where the floors had come totally loose and due to the plane hitting the corner of the South tower and the combined effects of the above the tower gave way at that point.

The North tower with the aerial was due to a weakening around the top reinforced steel roof which held up and kept the core in place, distributing the weight in a balanced way. Once that balance was disturbed and the core had to carry its own weight and due to the compromised core levels the building collapsed with the core accelerating first, which in turned dragged down the floors and outer walls.

Both towers were extremely susceptible to fire. An office fire out of control could have taken one tower down in the due course of time.

It is doubted whether such tall structures could keep standing indefinitely after similar plane crashes and conservative opinion is that towers can now be built to keep up for 8-24 hours. Emphasis is on maintaining the structure for sufficient time to evacuate all those inside. Obviously all concrete structures such as the Burj Khalifa may be able to completely withstand a plane crash. IMO all tall structures are subject to collapse as a result of unbalanced weight distribution and a failure at some point to keep up that weight.

I haven't studied the new WTC diagrams so don't know how far up the concrete goes. The more reinforced concrete there is the better the integrity of the structure. One thing that will always occur is pancaking if the top structure can be toppled and act as a sledgehammer to compress the floors below. Which is why earthquakes are more of a danger to skyscrapers than terrorism. The effect of an earthquake isn't localised but felt by the whole tower. The domino effect, fire, burst gas and water mains, panic, etc. exceed anything that terrorists could ever plan.

It is Saturday morning, new beams are going up right now and a lot of steel is laying on the 6th floor, including some really massive red things. Probably not the corner nodes though, the Big Reds don't seem to have moved.

It's really progressing now. Good to see after so many years.

Sorry but my English is not very good but thanks ... I always liked the previous towers and rebuild it makes me happy.
I have also seen that I already explained a lot, since as you greetings from Argentina

Its growing a bit faster, thats good news, amazing pics, thx !

Can we delete post # 12766 it's so distrubing especially for someone who lives across the street from the site.


Thank you

hmm guys with recent dip in new york office rental market.

will this building be commercial successful?

You build office space for the future not the present. Yes the economy is in a funk right now but it won't always be that way. This tower won't be complete until 2013 so hopefully things will be much better by then.

I love what is planed for the future. But.

So excited for the 20th floor. :3 I'm so glad that this beast is rising. ^_^

oh! my god,
the freedom tower is growing up faster than i thounght, i would like that in Mexico the towers were built so fast.

1WTC FTW.

Should be around the same height as 7WTC and 3WFC center by years end :)

There's what seems to be a very large piece of steel near the SE corner, sitting on the crane track.

Someone else had mentioned the same thing but there is a street between the two buildings and I'm thinking it might just appear that way due to the angle of the photo. I'm also happy to see that suddenly we can see a building rising after so much delay but I agree that the progress has picked up significantly. It's not all that exciting to watch photos of the prep work because you really don't see anything taking shape.

No, I noticed the street. I definitely noticed it because I've walked up and down it a few times. And yes, it may just be prep work, but it's prep work on America's biggest skyscraper project and it's prep work on a building that has much more meaning than just a regular glass and steel skyscraper.

I dont know dude but sometimes i dont think we should justify the long period of time the Prep work took because of past history of this place...i think it was a slow process under all terms and that basing the speed on the significance of the building is just not right.

I mean, the Burj Dubai (Burj Khalifa) was so significant in its own way and was such an important milestone for Dubai and the rest of the world, but it didnt take that long to be topped out...

Does anybody else share my thoughs, agree, disagree?

p.s: am not trying to start some conflict here, just showing off some of my thoughts...I love New York, my City!!!

Many people will visit here when this building's completed, i think so.

what are they doing to the crane at the south pool? Taking it apart? They have not finished the steel at the south pool yet..

^^Hopefully they are just changing the length of the boom, or performing maintenance or an inspection.

I mean, the Burj Dubai (Burj Khalifa) was so significant in its own way and was such an important milestone for Dubai and the rest of the world, but it didnt take that long to be topped out...But it wasn't built atop the bodies of 2,752 people, atop the wreckage of several major buildings. Just cleaning up the debris took years, and making the as many of the human remains as possible were reclaimed was a long and painstaking process. Then there's the fact that it's being built on an island, with the slurry walls that hold back the Hudson river needing to be replaced. It took years to get to get that corner of the site to the equivilant of a bare patch of desert, and even that they were building over an active PATH line. Were there avoidable delays? Absolutely. But even in the best case scenario, it would have taken much longer than a normal site to really kick into gear.

Does anyone know where i might find the building schedule with major milestones?

I agree with what you're saying but as far as that building across the street is concerned I don't think many people will even notice it when this building is topped out. They had to work within the limitations of the surrounding area as well as the locations of the destroyed buildings where the memorials will be located. Besides, New York City is covered with skyscrapers and it's not unusual to see very tall buildings right next to each other.

Once the fencing and pedestrian bridge over Vesey are removed the area will feel more open. I was around the WTC last August and it sure feels tight and clustered.

I'm not crazy about this design, but it will be really nice when this building is completed. Good to see that the construction seems to be progressing more quickly these days.

I know exactly what you're saying. I've spent enough time in New York to know there are plenty of highrises in close quarters with each other. I just thought that, given they have a rather large plot (at least, for Manhattan it's large) of land to use, they wouldn't resort to putting their main building right up against the street.

totally agree, the construction is progressing very fast.
Can the yankees give classes of construction to the chilangos?
hehehe.

I just thought that, given they have a rather large plot (at least, for Manhattan it's large) of land to use, they wouldn't resort to putting their main building right up against the street.It's because they wanted to restore Fulton Street, which was was cut off at Church St when they build the WTC superblock back in the 1970s. That wedged the Freedom Tower into the short block between Vesey St and the future Fulton St.

You also have to remember that while the superblock is a huge amount of area for Manhattan, eight of the 16 acres, or half the site, is occupied by the National 9/11 Memorial. Part of the reason Fulton St and Greenwich St are being restored is so that the site will be divided into sacred and non-sacred spaces. When restored, Greenwich St and Fulton St will cross, dividing the superblock into four uneven quadrants. The largest quadrant, the SW quadrant, is the "sacred" part of the site. The surface will be totally dedicated to the memorial plaza and museum. The other three, smaller quadrants, were therefore freed to be non-sacred and open again for commercial development:

Both the North and East quadrants are long but narrow. 1WTC/Freedom Tower and a future performing arts center will be wedged into the North Quadrant. Towers 3 & 4 will be wedged into the East Quadrant along with the Transportation Hub. The NE Quandrant is just big enough for 2WTC.

Likewise, it's the North and East Quadrants that are long but narrow.

Looks like they've been doing some controlled blasting today down near the transportation hub area. They had the blasting mats in place a few hours ago and they are hauling off the chunks of rock now.

It is the north side, it has something to do with the PATH tracks below grade. It does look weird.

Every time I look at pictures of this, I feel proud to be a new yorker. I hate the cheesy 1776 feet thing, but I cant help but admit that it's looking to be a gorgeous building.

Good info, didn't know about that either.

Does someone know any new from Foster´s 2nd WTC building? Is still alive? Or has being cancelled?

It's basically on hold. They will proceed with the Freedom Tower and 4wtc first. If everything turns out to work well and there is money to build the other 2 towers (2wtc,3wtc) they'll be built.

It's to avoid the PATH tracks, since apparently putting them properly upright would mean the steel would be in the middle of the PATH track.

Seems to me this would make that column less load-bearing than the rest^^

It's to avoid the PATH tracks, since apparently putting them properly upright would mean the steel would be in the middle of the PATH track.

Only the lobby section is tilted. it's vertical below grade and shifts back to vertical again at the 3rd floor connector. The horizontal displacement is about 5 feet.

wouldn't it been better to reroute the path?

It would be an enormous project to move anything in that area an inch. Those columns are so strong the tilt isn't even a tiny factor. None of them are moving.

Steel installation for One World Trade Center has reached the 20th floor equivalent level, raising the tower to 200 feet above street level, the Port Authority announced today.

The agency's Commissioners were given an update on the project today at the Board's World Trade Center meeting. Commissioners were told that steel has risen to the 20th floor equivalent level. To reach the 20th floor, the Port Authority's steel contractor, DCM Erectors, has already erected nearly 8,000 tons of structural steel - 700 tons more than the total amount of steel in the entire Eiffel Tower.

Photos of One World Trade Center are available on the Port Authority's Web site - www.wtcprogress.com -- and on Flickr.

Currently, ironworkers are installing 16 giant steel nodes on the 20th floor level. Some of the nodes are as large as 175 tons and as high as three floors. These giant pieces act as joints between the steel framing for the building's podium and the steel for the remainder of the tower, and represent one of the signature elements of the building's unique design and appearance.
The above-ground height is in addition to the 60 feet, or four floors, of the building below street level, which will contain mechanical space, fuel storage, water tanks, parking, retail and a lobby for the observation deck elevators.

Since construction began, more than 60,000 cubic yards of concrete has been poured for the tower, both above and below ground, almost as much concrete as was used to build the entire Empire State Building.The initial 20 floors of the tower consist of a lobby and several mechanical floors, which required more complex construction due to security and the configuration of the floors. The next 69 floors will be standard office floors and will be built at a quicker rate. The tower is scheduled for completion in 2013.Port Authority Chairman Anthony R. Coscia said, "The construction progress on One World Trade Center is great news, but we know more challenges lie ahead. The Port Authority will confront these challenges head-on as we continue with the rebuilding of the site."

Port Authority Executive Director Chris Ward said, "This progress is one more sign that the site is not a pit anymore. At the same time, we must continue working aggressively each day to keep up the momentum."

At the meeting, the Board also authorized the following World Trade Center-related actions:

An amendment to an existing agreement with Cushman & Wakefield Inc., to serve as financial advisors to serve in the offering of membership interest in 1 World Trade Center LLC.

An additional $4 million for design and redevelopment coordination efforts at the site through March 2011.

Additional planning funds for the design of the Vehicle Security Center. Work will provide for design development to help mitigate the impact of the delay in the deconstruction of 130 Liberty Street and advance the design of the basement structure.

Additional planning for the design of the Eastside Tour Bus Parking Facility.

A supplement to an existing contract with DCM Erectors Inc., to complete site preparation work for the build-out of the WTC Transportation Hub's steel superstructure.

A supplement to an existing contract with Tutor Perini Corporation to complete site preparation work to support Greenwich Street corridor construction.

1 World Trade Center LLC, through its construction manager/agent, Tishman Construction Corporation, to enter into a construction trade contract with Island International Industries, Inc. for the spray-on fireproofing work at One World Trade Center.

1 World Trade Center LLC, through its construction manager/agent, Tishman Construction Corporation, to enter into a construction trade contract with Fresh Meadow Mechanical Corp. for steam utility service work at One World Trade Center.

1 World Trade Center LLC, through its construction manager/agent, Tishman Construction Corporation, to enter into a construction trade contract with American Architectural Incorporated for the cable net walls and canopies work at One World Trade Center.

Assignment of a Memorial Foundation trade contract with DCM Erectors, Inc., for the furnishing and installation of the bronze name parapets for the 9/11 Memorial project.

That's because there aren't. 20 is just what they decided to call the first office floor.

anyone have more details of the current transfer floor? There's literally tons more steel there you can see now on the earthcam. It will be interesting to see how much actually goes into it and how it all ties together.

Also, are there any additional photos off the diagonal/offset (mid building) jumbo column on the north side of the building, perhaps a shot from further away?

Lastly, it appears they may be putting up the retaining wall or possibly the foundation for the waterfall on the south side of the north pool? :)

I don't quite count 20 floors yet but good progress and this one is really booking.

the height is right around that of a 20 story tower..... on a different note the setai had a special on tv about how it was built so I can almost gaurintee that this will have cameras documenting start to finish for some type of a show.

nice up date picture and also detail information....

can't wait till the real floors start going up! btw: this thread has over 3,000,000 hits, congrats lol :D.

700 tons more than the total amount of steel in the Eiffel Tower.
Holy sh....... :uh: :eek: :okay:

Uh...175 tons? Doesn't seem likely they trucked anything like that in one piece.

Wait, so they only have ~6 floors in the lobby portion, and then they jump to 20? So it doesn't really have 108 floors, they just chopped out 14. Doesn't any find that to be a terrible waste of space when they were able to fit a full 110 floors in the original World Trade Center?

There's no rule, or law, that says how you have to 'label' each floor. If the first office floor is the height of a 20 story building, that makes sense. Regular people will never get to go to these mechanical floors anyway. Come to think of it, every building in the USA over 12 stories tall has a floor mis-match. There are no 13th floors (That I know of)

I think the 20th floor is figured from the lowest underground level at 13' 4" per floor. Up till then they just use the actual floor number from ground level.

They start the office floors higher for safety reasons. The podium is a designed to be a fortress/bomb shelter/panic room, whatever you want to call it. I do agree its kinda a waste of space. But this is the post 9/11 world. Some argue this tower has a big bull'e eye on it. So the goal is to make it the safest office tower in the world.

cam is working again after it got stuck yesterday

I don't know why most of you care about how many floors it is. Most of you will never see it from the inside. They don't need every itch of the building, for it to be what it is.

No, the original WTC didn't have a full 110. They skipped floors just like this one. Not as many, but they still skipped floors for the lobby.

The standard office floors may look very similar to the exterior of 7WTC? With bevels on each corner. From that picture above, you could almost envision 7WTC lifted and placed on top of the 1WTC podium structure.

1wtc is no longer dwarfed by it neighbours :-)
nice pictures onn

can you see the new one wtc in the skyline behind the wfc wintergarden from a ferry ore somewhere??

Can anyone show me if there are any threads for the other towers going up on the WTC grounds (especially the one with the sloped diamond-shaped top)? Seems like there's nothing on them.

I know, I was thinking the same thing. Even the 767's which hit the towers on 9/11 only weighed about 150 tons. Which would mean that that one piece of steel weighs more than an entire 767. I'm sure Zen could answer.

Sorry to be the one to have to break it to you, but there is no Santa Clause, and the original Twin Towers did not have an actual 110 floors. In each tower, there was the lobby which was designated as floor 1, then the very next floor above the lobby was labeled as floor 7. There were no floors 2-6. The reason is was labeled floor 7, instead of floor 2, was because the lobby was about 60 feet tall and if you consider each floor to be 10 feet in height, the 60 foot tall lobby would be the equivalent of 6 floors. So they just labeled the floor above it as floor 7. Also, there were several mechanical floors which were basically just one taller than normal floor with an upper and lower level, so they labeled them as two floors even though they were arguably just one floor.

The new 1WTC is just following the same convention as the original Twin Towers (and most other high-rise buildings). The lobby is about 60 feet tall so they're just considering the lobby to be about 6 floors of the building. Then there are 5 mechanical floors above the lobby, below the lowest office floor (floor 20). Those mechanical floors are really tall and some have upper and lower levels, so height-wise they're just labeling it as 13 floors instead of 5. The base is a little over 186 feet tall, so if you're using the convention of 10 feet equals 1 floor, then that's 18.6 floors, or, rounding up, 19 floors.

I already covered it, and it's been said a thousand times, but maybe your post will finally shut people up.

I'll just say that according to our man on the scene, Zen, starting the offices at floor #20 was completely arbitrary. It kind of makes sense if you divide by 10, but if you divide by the actual floor height of about 14 feet you only get 14 floors, so it is all meaningless.

Sorry, but you are wrong. Twin Towers did actually have 110 floors. The lobby was said to be 6 floors tall because the core had 6 different levels, as we can see here:

Also, there were several mechanical floors which were basically just one taller than normal floor with an upper and lower level, so they labeled them as two floors even though they were arguably just one floor.

Despite being taller than a normal office floor, mechanical floors were counted as one floor each.


Floors 106th to 110th:

http://911research.wtc7.net/wtc/evidence/plans/doc/tvmast/CD_ARCH/A-A-178_2.png


And it's the same with the other mechanical floors: 7-8, 41-42, 75-76.

The total number of floors on each tower was 116.

Inside one of the two 110th floors: ;)

It's okay if you guys compare the old wtc with the new wtc. As long as it stays with the designer/technical facts and features. No political and terrorism discussions please.

Totally agree. :okay:

There may have been cores on those levels, but there were no real floors like the rest of the building. It looks like, at least initially, they had an office or two in the core, locker rooms, the mail room, and some storage. All within the core. And I definitely don't know where you're getting 116 floors from.

Taken from the NIST report itself:

The lobby was pretty big I can't remember how many story the new one going to be. I just know the base is 200 feet. Is windows on the world going to be the last stop this time around.

That red steel just looks denser than normal steel, doesn't it? I wonder how much heavier, say, a linear foot of that stuff is compared to normal steel?

There may have been cores on those levels, but there were no real floors like the rest of the building. It looks like, at least initially, they had an office or two in the core, locker rooms, the mail room, and some storage. All within the core.

But those were considered floors anyway, as you can see.

You wrongly consider by "real floor" a "normal" office floor: a floor can actually have different sizes, shapes, configurations, usages, etc.

And I definitely don't know where you're getting 116 floors from.

Very easy: there were 6 subbasement levels. ;)

Being this is still the WTC, I hope they engineer the building so the core could be like a shelter just if someone retarted had a retarted idea like in '93 and 2001. If I worked in this building definitely if I worked on the higher stories I would keep a parachute in the supply room. I'm not trying to be funny or an asshole. Just saying.

I'm so glad that this building is being built, and not on hold. Great Pictures, Great Progress!!!!!!!!!!

Nice photos NYCD! :okay:

Great progress since last time I checked up on this thread. Slowly but surely rising. They have started working on the steel above the V columns. Good to see.

looks that tower construction more solid then previous WTC twin tower...

I believe that from all the wtc reconstruction projects that had been proposed in the past, this is the best. And im glad that its construction is going fast these days.

Personally i was in favor of rebuilding the towers as they were, but this project is very good also.

The first office floor in WTC1 being 20 isn't meaningless. They use 13' 4" just like the office floors, but they count from the lowest underground level to come up with 20. If you look at any floor number after 6, all the way to the roof, the number only makes sense if you figure it from the lowest level, not ground level.

These beams are huge!:nuts:

Does anyone know when the corner nodes will be installed? :)

Does anyone know when the corner nodes will be installed? :)

No one's sure. They may have to install the next level of core steel to anchor them securely. If that's the case it could be a couple more weeks.

If they don't need the core steel then maybe as early as next week.

This project seems to be a 21 century version of a 20th century building... They should build two of them.

They've been pouring all day on the south side of the tower. Does anyone know what exactly they are pouring, is it the walls beside the core or is it on one of the lower floors?

I think it's the core. If you notice on the cam, the north core is taller than the south core.

There well be refuge rooms within the core on every office floor. The vent system draws air from the top of the tower so unlike '93 the tower well not fill with smoke.

That almost works, (70+187)/13.3=19.3233. That's is the best reasoning I have herd so far.

PS: the base is 200 feet square (column centers) by 186' 8" high, not 200' high.

no its not, if i remember correctly( this is 600+ pages ago)... world trade center base was 208 ft x 208 ft.. freedom tower base is 200 ft x 200 ft..correct me if i'm wrong

it seems like finally is growing faster! great

no its not, if i remember correctly( this is 600+ pages ago)... world trade center base was 208 ft x 208 ft.. freedom tower base is 200 ft x 200 ft..correct me if i'm wrong

And the memorial pools are a little smaller, 187' square I think.

It's so frustrating watching this tower grow at a snails pace, I was in NYC 6 months ago and it's not changed that much since, anyway with the base almost finished hopefully it will rise a lot quicker, and surprise me when I come over in May.
We have the Shard U/C in London, and it's rise from basement to almost the same height as this in under a month!!

You are either blind or trolling.

I'd also like to see some strength comparisons between the Shard and Tower One. Some of those connections on The Shard's exterior columns look pretty weak, and what grade is the concrete?

well at least still any progress....

After seeing the before and after shots, its actually quite remarkable the amount of progress that's been made since September. The base is probably the most complicated steelwork in the whole building.

Amazing a truck can haul that much !

^^

http://www.spacy.me/forum/wtc8feb.jpg

There are a lot of wheels on that truck. If it truly weighs 170 tons, and the max of a normal 18 wheeler is 80 tons, then double the wheels should distribute the weight almost the same. I can only count about 24 on the trucks in that picture. I thought the weight limit was way lower in Manhattan due to all the underground stuff.

The final east side node is ready to install this morning.

Meh,

I am not even thinking about comparing the 2 buildings, They are totally different structures, and don't misunderstand me it's not about London is better than NYC, I think Tower 1 is as good for NYC as the Shard is for London, in fact everytime I am in NYC I make a point of staying at the milleum Hilton with WTC facing room , just so that I watch the construction.

I only wish they'd have rebuilt the original Twin Towers, they were as much a part of New York as Big Ben is to London.

Having looked at the photo's from Sept 2009, it has progressed quite a lot, it's just a bit misleading because it hasn't gone up in height too much, but anyway should be going up rapidly now the complex base is done.:cheers:

The max for a normal 18 wheeler is 40 tons, including the tractor and trailer. Each trailer axle can only take about 9 tons. Any more than that and streets and bridges couldn't take the load per wheel. One connector was delivered on a three axle trailer/three rear axle tractor combo , meaning the connector couldn't weigh more than about 50 tons.
That 175 ton comment was just another reporter using numbers he didn't understand.

I was down there four months ago and I live in this city. And I can tell you for a fact that alot of work has been done. Not to put you out there but I don't believe you, when you say you were down there sorry. Because had you been down there, you would have seen its grown by 100 feet. And there's red steel all over which wasn't the case half a year ago, the last time you claim you been here.

http://wirednewyork.com/forum/attachment.php?attachmentid=8406&d=1265651689

This floor almost done so its taking about 2 weeks to get it finish. I'll wait to visit it when its taller then the shortest building near it.

That there is progress is undeniable but the speed of the construction is debatable.;)
I heared not so long ago that they were aiming for a floor in a week or two, but reaching the top of the base has taken more time than that.
Perhaps the construction will speed up as they will begin with the 'normal' office floors, who knows.
Looking with some criticism at the wtc site is not that bad, you just need make sure that it doesn't become blind trolling.:lol:

I wouldn't call the current speed debatable. It's been moving quite fast in recent months. The 1 floor per week statement had nothing to do with the base, which, according to the Port Authority, is supposed to be done during the first quarter of 2010. We're pretty much right on schedule now.

looks the traffic management its not disturb by WTC construction activity....

Yeah they said nothings change in 6 months and we all that isn't correct.

they have installed all 3 nodes on the east side of the building. yay

This looks great,Freedom Tower Is powering along.Whilst SHARD in London is a Beautiful building and a fine addition to the London Skyline,you cannot compar these two they each have their own uniqeness.

It's looking more and more that the performing arts center won't be built and tower 2 and 3 will both only be 6 story nubs which will be converted to retail space.

So in other words, our beloved ground zero will be converted into a very expensive strip mall.

Normally, for obvious reasons, the concrete core is erected before the steel structure. So, I think they will complete the core in the base before to go further. Someone has a clue about this?

I'd think that since the concrete in the core can't go any higher than the lowest part of the crane structure it would always have to lag the erecting steel by a few stories. And so far, the outer steel has been going up as soon as the erecting steel for that level was done.

It is amazing that the Shard is going up at a extremely fast rate. Also the Tokyo Sky Tree is almost a supertall after 6 months! But this isn't a who is the fastest contest, is it? I think 1WTC is so much stronger (not going to debate, just pictures) and also check out the Pentamonium core rebar...

You're thinking of the slipforming process which was perfected in the 1980s. That process is ideal for less complex construction that requires little more than a hastily poured concrete service core and steel framing. This tower is more complex and has redundancies designed into it that you won't find in an ordinary tall. I think that there has to be variegated coreplates that disallow dragging the same form up as the framing slowly rises below.

that is so incredibly dumb. embarrassing. why'd they make the renders and all that if they wernt even gona be able to afford them?

Wernt even gona? Now THAT'S embarrassing!

It's looking more and more that the performing arts center won't be built and tower 2 and 3 will both only be 6 story nubs which will be converted to retail space.

So in other words, our beloved ground zero will be converted into a very expensive strip mall.

source? :? do you have some inside information we don't? or is it just rumors?

they have installed all 3 nodes on the east side of the building. yay

Looking good! We'll get to see that floor finished soon with the steel supports, sheeting, and the unique corners on this floor.

I also just noticed the lift on the south side of the building that has probably been there at least a week or so.

Theirs no news about it, since it still in court and the case is still up in the air. Silverstein hasn't giving up. And why are people talking about tokyo sky tree here that isn't a skyscraper so it going to get built much faster.

It is amazing that the Shard is going up at a extremely fast rate. Also the Tokyo Sky Tree is almost a supertall after 6 months! But this isn't a who is the fastest contest, is it? I think 1WTC is so much stronger (not going to debate, just pictures) and also check out the Pentamonium core rebar...

Faster... doesn't mean better... and after 9/11 ... you sure wan't a better construction than the twin towers... so ... wait...

it's a very tense situation right now, in the next weeks the future of the WTC will be revealed. there are a lot of rumors spreading around, most of them are BS, but i'm afraid of the ones which prove to be true. i'm going to search the WNY forum a bit, maybe there are some more reliable news...

These are not the "175 ton nodes" mentioned in the press release. These puppies only weigh about 35 tons.

The big nodes are at the corners, are about 90 feet high and come in two parts.

The one on the right.

I'm to really worried about that as long as they finish this building I can see it from jersey.

I wouldn't worry too much, a major contract is to be awarded by the end of the month (or early March) rendering most of the negative stuff moot.

What does that mean? A contract for what? The port authority can't do anything unless the court agrees to it.

You assume too much.

The PA controls the entire site except the Silverstein towers.

I refer to the Transit Hub.

One would be mistaken to assume it's just a pretty building above grade. It is probably the single most important (and most impressive) part of the WTC rebuilding, and it is going forward.

Oh okay, I got ya.

Big snowstorm on the way to NYC. Probably won't be much happening for a while...

It's snowing.:ohno:

I'd think that since the concrete in the core can't go any higher than the lowest part of the crane structure it would always have to lag the erecting steel by a few stories. And so far, the outer steel has been going up as soon as the erecting steel for that level was done.

You're thinking of the slipforming process which was perfected in the 1980s. That process is ideal for less complex construction that requires little more than a hastily poured concrete service core and steel framing. This tower is more complex and has redundancies designed into it that you won't find in an ordinary tall. I think that there has to be variegated coreplates that disallow dragging the same form up as the framing slowly rises below.

Thank you for your answers. But, according to this announcement, the construction above the base should be more standard:

http://www.panynj.gov/wtcprogress/index.html

(...) The initial 20 floors of the tower consist of a lobby and several mechanical floors, which required more complex construction due to security and the configuration of the floors. The next 69 floors will be standard office floors and will be built at a quicker rate. The tower is scheduled for completion in 2013. (...)

So, the question remains: When the base will be completed, does the concrete core will go beyond the steel structure? (sorry to be so picky, I still wonder why they build the core this way)

The concrete core well never be above the steel. The steel must be above the concrete core walls in order for the floor steel to bolt to the core steel.

Think of the core as the trunk of a tree and the floors are the branches of the tree, but the branches go up before the trunk.

couldn't put it any better. Its snow pretty good out here.

On the topic of snow, I am very disappointed that while the east coast is getting buried with snow,seattle hasn't had anything except a measly half inch this winter :ohno:

I thought I'd remembered that the floor connections to the core steel were outside the concrete, but I might have been hallucinating again. Dang the 60s anyhow.

that pic in the snow looks great!

Ewww...

Well Manhattan recived very little snow last satruday compared to southern Jersey (i live in somerset and didn't get much snow either") ,which is a good thing for 1 WTC.

On Saturday, here in Philly we got 28.5 inches of snow -- the second highest amount in a 24 hour period since they started recording these statistics 125 years ago. Today we are getting up to 2 more feet of snow. Philly is 90 miles southwest of NYC.

I wished it snowed in my country too:ohno: here in Portugal the only place we have snow is in the mountains :lol:

yeah its been pretty bad all day today (wednesday). around half a foot right now, but its supposed to snow through the evening.

couldnt imagine a snowy construction site. what temp would it be in NYC today.? here in sydney im sweltering at 35deg..

It's about 1deg (34deg F) right now. Feels like -5deg (23deg F) though.

in long island out in the east of nyc. blizzard conditions. this probably means slow progress in the wtc for the next few days

The Port Authority should be releasing its 2009 Q4 report any day now. Last time they released it (the 2009 Q3 report) on November 9, 2009 and it's usually about the same each time, like a month and a half after the quarter ends.

I was thinking the same thing, I've been checking wtcprogress.com a couple times a day looking for it.

Looks good:okay:

great job new york

out of curiosity... who and where is the pre-fab being done?

I heard that the snowfall in NYC in last hours was little heavy. Anyway that might cause a delay or problem to the structures (WTC1)?

I'm sure there are days 'built in' the schedule for bad weather. I can't imagine any structural issues.

It wasn't just a little heavy it was heavy.

its getting higher...

I reckon it helps restore the atmosphere in NYC to see a building rising in that spot... And what an amazing construction site!

we're not down in NYC. Alot of people out here aren't fans of skyscrapers. A handful of us will be happy to see it.

Uh, use RGZ cam to look at the SW corner. Is it what I think it is?

People shoveling snow off 1WTC?

construction is too slow.. when its done, it wont look modern anymore. It'll look like designs last decade LOL

I present another possibility, construction elevator tower sections.

I didn't want to speculate too much about the corner nodes untell I saw the first section go in.

After doing the math what we see in the pics is the bottom third of a corner node.

It's perfectly logical, the hight of the node section is roughly the same as the hight of the core steel column sections.

It is a crane after all, looks like a crawler. No idea what it's for though.
