4 World Trade Center - 150 Greenwich Street

Mr. Maki’s Tower 4 at 150 Greenwich Street, between Cortlandt and Liberty Streets, is the most understated of the lot, with a sheer curtain wall. The 61-story tower rises for most of its height as a parallelogram and then, nearly 700 feet in the sky, it becomes a trapezoid, reaching an overall height of 975 feet, with no antennas. The upper part of the facade inclines toward the towers to the north and is meant as a unifying gesture.

Out of Towers 2, 3 and 4, Tower 4 is the most ahead in terms of progress.

BTW, it's called "4 World Trade Center," not 2.

I thought Tower cranes were due to be erected over the weekend? For this??

Not yet; it was just a bigger mobile crane near the corner of the site and pics are in the old thread.

So, i guess oklahoma city didn't teach anyone anything. That beam and post arrangement for the lobby is so totally unsafe for a building of that height given where it is being built. All anyone who doesn't like usa or that building has to do is park a truck with enough stuff in it and down comes the whole thing across the street and into the memorial. Aside from that it's rather bland. I hope it doesn't end up like #7 big fortified metal monstrosity at street level.

ok mr engineer.

about time we got a thread for these tower. At less one for it by itself

@ Metsfan, this one and #7 have one major difference, #7 has got a substation in it's base and this one just a lobby. So i don't think this one's base will end up like #7 one's!

About the design, mhhh I really don't know what to say. Surely it will be one massive building, but mhhhh it's bland. It has no character, it's just a box, which has a diagonal cut at a certain point and from that point it goes further up.

ups, fixed it :)

A building shaped like a box can look pretty and having character but if this building has it?
I'm not sure.:lol:

This building is going to have a RC core so a truck bomb taking out one exterior post isn't going to bring it down. It also shouldn't suffer the same fate as #7 since the likelihood of an out-of-control fire burning for 5+ hours with no water to fight it isn't exactly high.

Yes, but the side where the post is taken out could in theory collapse. I feel compelled to write a email/call about this. It's setting off all kinds of alarm bells when i look at it. You would think they would include some other bracing like an arched truss or diagonal beam in the gap. I've rolled it over in my head since i made that previous post & it really does bother me even trying to think what they coulda done to strengthen it somehow without it being seen... thankfully there's still time to make changes if they do in fact need to.

^ I'm sure that you can teach the engineers a thing or two.

I'm very pleased with how it's progressing. :cheers: It's starting to look more and more like how FT once looked.

again, another retarded post. im sure you know infinitely more about construction than the engineers hired for this project... but who's to say they didn't do anything to strengthen it somehow without it being seen? because you know... you wouldn't be able to see it if they did.

I'm very pleased with how it's progressing. :cheers: It's starting to look more and more like how FT once looked.

11 times square also looked similar. Funny, the big hole that used to be there is filled with building now! :)

- A

cheers ebola, the site will look like the freedom tower's in a years time or less.

Without the PATH tracks interfering, this should progress much quicker than 1WTC.

^^^ VERY good point, man.

I almost forgot about that. Now the whole thing about Tower 4 topping out before Fredom Tower seems to make more sense. Also, I think the plot is less complex so it should go smoother. But for now, I think FT may top out first. Tower 3 should look like how Tower 4 looks now in a few months, and I'm sure that Tower 2 will be right behind T3.

I'm going in 2 hours. I'll get new photos if i can.

- A

Damn that's a big hole...
Nice to see some updates, thanks!

When are cranes being erected for this?

damn I had no clue it was this far along. And at 975 feet why shouldn't it top out first, It's only 375 feet shorter then FT roof top.

When are cranes being erected for this?

They'll be removing the 150 ton crawler crane in mid December. I'd imagine they wouldn't do that until after they have at least one tower crane in place so you might see one in less than a month.

Thanks for the info.

Man, after seeing how fast this tower has progressed in just a couple of months, I hate to think "what if" 1WTC had been built in this plot or maybe 2WTC's plot? 4WTC and 2WTC plots are going to be a lot more 'user friendly' than its current site in the NW corner. Think about how much further 1WTC could be right now. It'd probably be about 100 feet high already.

Oh well.... too late now. But really great to see this one progressing quickly.

Politics keep tower one from growing. design changes a little dumb sh!t. Alot of people would rather see it dead then see it built. No matter there somewhat on track now thats all that I care about.

Silverstein exec is ‘frustrated’ with Port’s W.T.C. progress
By Julie Shapiro | December 02, 2008
Downtown Express



Silverstein Properties maintains this wall, built by the Port Authority, is in the way of its construction of Tower 4 on the World Trade Center site, but the Port says the wall is outside the property line. The dispute is in arbitration. Silverstein's 7 W.T.C. is the tower in the background.

Janno Lieber, head of World Trade Center construction for Silverstein Properties, has no tolerance for unnecessary delays.

When a projector wasn't ready for his testimony at a City Council hearing Friday, Lieber decided to start without it.

"I don't want to kill time," he said. "It's the one thing I...I refuse to waste time."

That characteristic surfaced again and again as Lieber spoke about both the progress and the uncertainty at the World Trade Center site, where Silverstein is charged with building Towers 2, 3 and 4. Lieber responded to City Councilmember Alan Gerson's questions, painting a picture of a company quivering with anticipation to plow forward.

"Our organization is not interested in dragging this out," Lieber said. "We want to keep the construction we have underway going. We've got both general contractors and subcontractors hired, on board, ready to go."

But all the energy in the world can't change the fact that Silverstein's towers will not rise in a vacuum. They are dependent on many of the projects the Port Authority is building: the PATH hub, the Vehicle Security Center and a new Greenwich St., along with utilities and other infrastructure. The memorial, which the Port is also building, has a less direct effect on the office construction.

The Port announced a revised timeline for those projects in October, with dates years later than had previously been publicized. Lieber said he is still trying to figure out how those delays will impact Silverstein's towers. That is a particularly difficult task because the Port has not released the data and risk assessments that produced the new dates, Lieber said.

"We are all wondering and getting kind of frustrated with the progress, and rightfully so," Lieber said.

But Lieber pointed out that in the meantime, work at Tower 4, in the southeast corner of the site, is going forward at full speed, with the below-street-level appearance changing week by week. Tower 4 will be complete by the second or third quarter of 2012, Lieber said.

That is, unless the construction hits a wall - literally. The Port Authority was supposed to excavate the Tower 4 site, but rather than clearing it entirely, they put up a 400-foot wall right where the western columns of Tower 4 will go, Lieber said. The wall holds back a mound of land beneath the No. 1 subway box - land the Port was also supposed to excavate, Lieber said.

"They weren't able to get it done, so they put up the wall, and for whatever reason they elected to put up that wall smack on the foundation," Lieber said.

The wall hasn't slowed Tower 4 construction yet, but it could if it stays there.

A Port Authority official said the wall is outside the Tower 4 footprint, and it will stand until the Port excavates beneath the No. 1 subway and braces it with steel.

"The issue is whether the wall is on Silverstein's property or our property," said the official, who spoke on the condition of anonymity. "We're saying it's on our property."

The question of the property line could be an expensive one. Over the summer, the Port was paying Silverstein $300,000 a day for missing the June 30 deadline of turning over the sites for Tower 2 and a piece of Tower 4. The Port stopped paying in October, saying the sites were ready. Silverstein contends that the sites are not ready and that the Port still ought to be paying the daily penalty.

Silverstein and the Port could not resolve the dispute on their own, so they entered arbitration this week. A binding judgment will likely come next week, the Port said.

This will not be the last time the Port Authority's work affects Silverstein's towers. No matter how quickly Silverstein builds Towers 2, 3 and 4, the space will be impossible to rent if it still sits in the middle of a construction site.

"Companies want to come to a place that feels finished," Lieber said.

The city and Port have committed to lease 600,000 square feet each in Tower 4, which will fill two-thirds of the building.

Lieber spoke Friday of the many pieces of the site that will need to be in place for the towers to open - and all of them are outside of Silverstein's direct control. Silverstein will need access to loading docks through the Vehicle Security Center, which will not be done until 2012. The new PATH hub will help attract office tenants, but it's not scheduled to open until the end of 2013 or the beginning of 2014.

"We're working with the Port Authority to try to figure out how reliable those new dates are," Lieber said. "Then we will have a discussion with them about how that impacts our schedule."

One of the largest question marks in Lieber's mind is Greenwich St., the front door to Silverstein's towers. In October, the Port announced a new top-down construction of Greenwich St. that would allow it to open by the end of 2012, but Lieber said he has not seen details of how the top-down method will work. The Port is working out the details of the design, but the sooner they can share it, the better, Lieber said.

"If any adjustments need to be made because of their new top-down [construction], it needs to be addressed very, very quickly," Lieber said. "So we're urging them to pick up the pace on that dialogue."

Greenwich St. is a particularly complicated project because of the layers of infrastructure: mechanical space and parking on the bottom, then the No. 1 subway line, then utilities, then the streetscape itself.

"It is the north-south spine of this project," Lieber said. "So it is very, very clear that you cannot have a functioning rebuilt World Trade Center if Greenwich St. is not finished and operable."

Steve Coleman, spokesperson for the Port Authority, did not comment on Lieber's requests for information sharing. When Chris Ward, Port executive director, outlined a new direction for the W.T.C. rebuilding last summer, transparency and stakeholder cooperation were two of his key points. And while the stakeholders did meet over the summer, communication has apparently grown less frequent since then.

At Silverstein's towers, construction schedules for Towers 2 and 3 are behind Tower 4, and Lieber could not say Friday whether they would open by 2013 and 2014, as was planned. The dates will depend on work on the rest of the site. Work at Tower 3 was on hold for several months earlier this year while Silverstein negotiated with Merrill Lynch over a possible redesign, but that deal fell through.

During Friday's hearing, Gerson repeatedly asked Lieber if the financial downturn would prevent Silverstein from raising the money to build his towers. And, repeatedly, Lieber said it would not.

Usually, builders of office towers must secure tenants in order to secure private construction financing. But Silverstein already has the money to build the towers, a combination of Liberty Bonds and insurance funds, Lieber said. That gives Silverstein the flexibility to build even during a poor economy, and find tenants later. Across from the Trade Center site, Silverstein built 7 W.T.C. using the same financing method.

One potential wrinkle is that Liberty Bonds are set to expire at the end of 2009, which would not give Silverstein enough time to sell them. Usually the bonds are sold near the end of the construction process, not the beginning, so it would be hard to find buyers within the next year. The Port Authority is speaking to Congress about extending the 2009 deadline, said Coleman, the Port spokesperson.

The question remains, though, of who Silverstein's tenants will be. Silverstein is building trading floors, though few financial companies are looking to expand now.

"We're not building for this market," Lieber said. "We're building for another market five years from now. It may be good, it may be not, but it's a different market."

All of Silverstein's towers could be used as conventional office space if the financial sector is still suffering in five years.

Lieber, though, is more optimistic.

"New York is going to come back gangbusters," he said.

Good news, they've installed the first set of forms for the core walls of tower 4. They're also preparing parts of the first basement level for concrete pouring. I'm sure it won't be long before we will see this beauty rising towards the sky :cheers:

Impressed by what will be the new world trade center, and this tower is really impressive, good design, simple lines but the design of very good taste.

Surely without a doubt WTC4 is the most progresses construction in the ground zero after freedom tower. The site is getting very organised and starting to shape up.

The green rebars visible at the bottom left corner of the ground zero webcam, its installed recently and we should be seeing more concrete pour becore turn of the year then.

I'm really looking forward to see some new pictures from this part of the wtc site.

It seems like there has been a lot of progress on this tower in the past few weeks. Can't wait for the next picture update.

Edit: A bunch of improved renderings have been released.

20-FT. WALL HOLDS UP TOWER 4

http://www.nypost.com/img/cols/stevecuozzo.jpg

December 16, 2008

WHEN the Port Au thority and Larry Silverstein announced last week's arbitration decision involving World Trade Center construction, the big news was the $50 million in penalties the PA must pay Silverstein over delays in turning the sites over.

What matters more to the public, however, is the impact on Tower 4 - the first of three skyscrapers that Silverstein is to build at Ground Zero.

After all, there's still a World Trade Center to rebuild - to some extent irrespective of the financial meltdown and a widely predicted lack of demand for new office space.

Tower 4 is the smallest of the new structures, but it's still a massive, $1 billion-plus project with 64 floors with 1.8 million square feet of office space.

Even ardent enthusiasts of getting all the towers up as soon as possible recognize that the PA and Silverstein might have to recalibrate the time frame for sites 2 and 3.

But the Fumihiko Maki-designed Tower 4 is another story. The PA has committed to leasing one-third of its 1.8 million square feet to use as its headquarters.

Silverstein also has an option "to require" the city to lease 600,000 square feet more.

With so much going for it, New Yorkers expect to see it rising skyward by the 10th anniversary of the 9/11 attack.

But a wall the PA put up to shore up the earth beneath the No. 1 train subway line box stands on the western side of the Tower 4 site - causing the arbitrators to say the PA did not deliver the site to Silverstein "in construction-ready condition" by a deadline earlier this year.

Sources familiar with the project say the wall "impedes the footings and foundation" on the Greenwich Street side. Until the PA can get rid of the wall, it will potentially have a serious impact on the tower's completion date.

"The footings and foundation are basically done except for where the wall is," said a source familiar with the project.

"If Silverstein could go full-bore, it would probably be done in 2012. If they dismantle the wall fairly soon - like next spring - they might be able to accelerate things and still make the deadline.

"But if it takes longer, who knows?"

Silverstein reps declined to comment. PA spokesman Steve Sigmund said, "There is ongoing construction on the Tower 4 foundation and the wall is not an impediment to that construction.

"The two portions of the retaining wall that need issues resolved make up about 20 to 25 feet of the approximately 200-foot wall. We are working with Silverstein on how to resolve the issues on these parts of the wall to support the foundation footings."

ooo woopy do :ohno:

of people dont know what wall it is, here it is..

what the hell was they thinking put that wall up there. that just looks lazy as hell.

ooo woopy do :ohno:
If it's in the way, it's in the way and a problem. Nothing trivial about it, just a small piece of the wall can hold up the $1 billion building.

^^^^ Yeah I didn't get it either. The walls in the way because thats where the tower is going. It means they haven't removed all the dirt the wall is holding up and that's the problem.

Some new images of tower 4 from wtc.com (http://www.wtc.com)
Pictures were taken on the 5th of December. The foundations of the core are finished and forms for the first walls are already in place. The foundations for the perimeter columns are also progressing very well. I assume they are ready by now. Within a few weeks this building should start to rise :cheers:

The progress is amazing on this tower. I wouldn't be surprised if this one overtakes 1WTC by next spring. I wish the webcams had better views of this site.

yeh, a better webcam for tower 2-4 would be nice

what the hell was they thinking put that wall up there. that just looks lazy as hell.

It was constructed to get the 1 line running again to south ferry. Not sure how many people realize this, but the subway line right now is basically a temporary box constructed from the remnants of the mostly crushed/destroyed tunnel that ran through there before 9/11.It may look sloppy, but it's only because it's not a technique that involves aesthetic concerns. It's strictly what needed to be done when it was done, no frills, but not lazy.

I'm pretty sure the PA thought leaving the braces in was a good idea, or they would be gone. There is very little shoring up that tunnel right now. There is still a lot of work to be done to reconstruct the subway tunnel and station, and the PATH station to its permanent configuration. You can't expect a building's time frame to have higher priority than a tunnel carrying passengers at speed.

I wish this tower could rise as smooth as it can unlike its unfortunate brother freedom tower, where its growth hormone still hasn't kicked in for it for 7 years.

It'll be interesting to see how they remove that retaining wall without disrupting service on the 1 line.

Good progress. I guess the formwork is just the core of the tower?

As excited as I am about the core developing for tower 4, I can't help but glance over at the future outline of WTC 3... it's going to be just a massive tower.

Its starting to get more exciting now. Ive lost all enthusiasm for 1 WTC now.

I 'd like to see more recent pics. :)

Awesome, it really taking shape now:)

When are tower cranes going to be erected?

When are tower cranes going to be erected?

probably not until spring/summer, this is a guess question you are asking here

At least one tower crane will be erected in about three weeks.

Hurrah! I'm not going to go on the WTC 1 thread, I havent done for many weeks, Im focusing more on this beauty because progress is 100 times quicker.

When are tower cranes going to be erected?

lowermanhattan.info reports it will be installed Feb 14th.

4 World Trade Center a Rising Reality

The muddy floor of the east bathtub has become mostly concrete at the site of 4 World Trade Center (WTC). It is a tangible sign of progress, and a long-awaited one for leaseholder Silverstein Properties. The developer has eagerly prepared for this phase of physical construction, spending months planning, finishing design documents, drawing up contracts, and procuring materials.

At the same time, the Port Authority, which owns the WTC, devoted countless man hours over the course of roughly two years to excavate the site down to bedrock -- an effort that allowed Silverstein’s groundwork to begin last winter, even as Port Authority crews continued digging on the site’s western edge.

“It’s a long duration, and there have been challenges,” says Scott Thompson, Silverstein’s project executive for the tower. “There are a lot of uncommon logistical issues, like coordinating our work with the [WTC Transportation Hub] project, and working next to the 1 train box. But we have a great architect and a great design team, and we are building.”

Located at the site’s southeast corner, with the future address 150 Greenwich Street, “T4” was designed by Japanese architect Fumihiko Maki. His minimalist vision for the 64-story tower completes Daniel Libeskind’s master plan, which uses the four WTC towers as an abstract spiral descending towards the National 9/11 Memorial.

At 975 feet, Maki’s is the shortest of the east-side towers, standing out for its sleek, glass façade and two distinctly shaped floor plates. From the base to floor 46, the 44,000-square-foot floors will take the shape of a parallelogram, echoing the shape of the WTC itself. From floors 47 to 63, the 34,000-square-foot floors form a trapezoid. The result is a major setback on the western side, like a single step downward toward the Memorial plaza. (Read more about the design here.)
Work on the tower’s foundations began in earnest in fall 2008, but only after a major pitfall was overcome -- or filled in, rather. This summer, Tishman Construction crews excavated the site’s soft schist to reach 40- to 60-ton bedrock, the sturdiest form of earth at the site, and the only kind that allows such a massive skyscraper to rise.

As test borings were done, geologists began seeing rocks considered unusual for this area, such as red shale, sandstone, and gray basalt. Knowing that Lower Manhattan is home to a glacial valley formed roughly one million years ago, geologists determined that the T4 rocks were deposits from a glacier that advanced from the Palisades an estimated 20,000 years ago.

When its ice began to melt, raging streams of water flowed in front of it. The sand, gravel, and boulders it carried downstream were caught in the currents, bouncing across the bedrock -- essentially sandblasting away the softer layers of rock. As a result, deep potholes and larger basins were carved out to form a “glacial swirl.”

“We thought we had hit a boulder,” says Thompson. “But the more we excavated, the more it was clear this was something very different.”

Construction crews continued to dig deeper, eventually uncovering the full pit the glacier left.

In order to build, the hole was filled with high-grade concrete. The level surface, surrounded by steel-and-concrete footings now being installed, forms the tower’s base slab and foundations at about 80 feet below the street. That base construction also includes the future WTC’s Vehicular Security Center ramp, which curves around the building’s southeast corner.

At the center of the site, the tower’s sub-cores are taking shape, and installation of the first of three tower cranes in mid-February will make construction progress even more obvious -- and faster.

Thompson says that as long as harsh winter weather doesn’t cause more concrete-curing delays, the next few months of building will bring the cores up several levels, creating the sub-grade mechanical floors and lower-level retail concourses that will link to other WTC structures.

Infrastructure, including T4’s fuel cell, electrical, and other utilities, is being built as well. That work includes details like finalizing contracts with the various subcontractors and trades to keep the project moving ahead towards substantial completion in 2012.

By this September, Thompson says the tower base will begin to rise above street level, with the steel superstructure following soon after. His team also is coordinating with the Port Authority’s excavation on the building’s west side, expected to wrap up in late February.

“This job is unique not just because of the site’s history,” Thompson says. “It’s unique in its own right for the level of complexity. Beyond the regular construction, we’re building 36-inch-thick core walls, redundant safety systems, green-building components -- and there’s tremendous coordination through all of it. Most other buildings in New York are simply not like this.”

street level by september he had better live up to that or he want be able to live it down.

Good pictures. We should be seeing the first tower crane in one week.

As i've seen these are mostly mobile cranes. The BIG mobile crane that was next to the PATH entrance is gone and replaced by a much smaller mobile crane. THe site seems to be swarming with much more activity as well. I'll take more photos next week but post the few i got here & tower 1 thread because they show the whole site.

Nice progress :)

There will be a fuel-cell in the basement?

There will be a fuel-cell in the basement?
Yes, it's their contribution to reducing their carbon footprint. The hydrogen will be trucked in after being generated at a remote site with electricity produced by windmills. Personally I think the idea of putting fuel cells in the heart of Manhattan is just inviting a terrorist attack.

wow what a close up of the work. Those concrete at the foot of the tower must be dense.

It's not just a contribution to reduce co2 emissions, it is simply a way to store energy. Just like most other skyscrapers have oil tanks with generators for emergency situations,to keep up emergency systems and vital functions such as fire alarms, lighting and other things. Depending on the storage system and generator used to transform the hydrogen into electricity, it will be less/more/same advantage compared to oil storage. As for chemical instability, it depends on the storage system used to store the hydrogen (and I'm pretty sure the engineers have thought about it enough time, since it is their job). Same problematic can be found with oil (highly flammable as well), therefore it depends on the technology used. If it was riskier than oil, engineers wouldn't have used hydrogen in a multi-billion dollar project for absolutely no reason.
As for the risk in a terroristic attack, it is stupid even to consider: it will be in an underground chamber made out of reinforced concrete as a plus other than the reinforced container that will keep the hydrogen. A risk that is not even worth to discuss in an internet forum for skyscrapers.

Hydrogen is definitely a lot more riskier than oil, but i agree there will be a good fail safe system.

is this just a wild-ass guess or do you have some knowledge that fuel cells pose a special hazard?
Fuel cells are fueled by hydrogen which is extremely hazardous to handle and use. Even in very small concentrations it can explode or burn. In addition it's molecules size is very small so it's very hard to contain leaks at any joints in the system. Detection systems are absolutely required to detect leakage.

How they decide to built a fuel-cell in WTC area knowing that its dangerous...?

It's not dangerous. My goodness. Two terrorist attacks in 200 plus years of NY City. If they want to attack, they are going to do it regardless of how any building gets it's power.

did you just ignore my comment? I'm not going to write it again.....

What you people are saying about the fuel-cell is dumb. Terrorist didn't attack WTC with Hydrogen powered cars or the Hindenburg, they did it with Jet fuel powered airplanes. We been through this a thousand times on the WTC threads, it most be safe enough otherwise they wouldn't be using.

You folks obviously don't have any idea how dangerous hydrogen is. It's colorless, odorless and extremely volatile. Having it stored in the basement of any building makes no sense, having it in the basement of a skyscraper in Manhattan is just ridiculous. One person in a couple of minutes could very easily sabotaged the system to create an explosion to instantly level the building that was contained in. I don't care how safe people think it is the potential is so great that I don't see how they could justify its installation. I guess being "green" trumped everything else in this case. :bash:

^Yes, because that's all they think about when designing buildings. Green is all they go for when designing the look and feel of a building, as well as it's power source. Designers will use whatever they please just so they can get a green rating on their building....please, get a grip on what comes through your keyboard. That statement makes you look completely ignorant. :ohno:

Those are some great pictures. Nice to see what is actually going on over at the T4 site since it's mostly blocked from the webcams. It's exciting to see the whole site really start to take some shape.

natural gas is tastless, colorless, odorless and extremely volatile. But that doesn't stop me from using it in my home. So what you'd just said has no legs to stand.

Talk about blowing stuff out of proportion. I don't think hydrogen fuel cells work the way you think they do. It isn't like the Hindenburg. Oh, and did you know that vehicles run on a volatile hydrocarbon called gasoline? I can't believe that they allow them in NYC!

So were gonna start seeing the first floors till September???

When did they start all of the construction?

construction started last year and yes you should see first floors in fall.

just for fun of semantics... fuel cells do not mean hydrogen :)

It's incredible how much ignorance you were able to show in only one comment. You have the arrogance of justifying with futile reasons the expertease of dozens of engineers telling them how to do their work. As a civil engineering student, I can just pity you, but remember how absolutely useless your thought is regarding things you have no word in.

I'm not talking about terrorist :nono: absolutely not
I was talking about human error, an accident...

I'm glad you're a student because you'll learn over time that expertease is a relative term and used much too often. We've already seen that with this complex of buildings politics trumps reason in many cases. Common sense has nothing to do with the design of these buildings. Politics is a reason it's taken so long to see anything happen is also the reason that many decisions that were made were not based on solid engineering. The fuel cells is one of those decisions, they were only installed for political reasons not for any truly economic nor engineering reason.

Does anyone know if they are still erecting a tower crane up this weekend?

^^^^I haven't heard anything about it.

All I know is this, I don't care what they use to power the building. As long as it gets built and as long as it safe. I can't say why they do anything, I wasn't there. And Silverstein is one of my fav five so we don't talk. So anyword on the matter outside the box is hear say. Big pitcure, thats what we need to focus on here.

whoever lives in NYC keep an eye on WTC4, they should start installing first crane this week according to the schedule :)

I wish I could but I stay in scranton Pa home of Americas the office it really sucks sorry.

I personally don't see a lot of intrinsic danger in having hydrogen stored in the basement. I am sure there could be accidents, but the fuel cells will probably have redundant safety systems. I do agree with Msradell on the fact that this was a political decision. No engineer who has ever heard of efficiency would support this kind of thing. They want to take an inefficient process and turn it into three processes. Instead of having the offsite wind turbines directly supply their electricity into the power grid, they elected to have the wind turbines produce electricity to produce hydrogen gas to transport to the site and produce electicity again. I would think that at most this elaborate scheme is half as efficient as directly supplying the power grid with clean energy. If they really wanted to have the WTC site be associated with green building, then why didn't they allocate money to build wind turbines elsewhere and claim that the site is funding clean energy or specify that the site only buys renewable energy from the energy company? Instead they created this fuel cell idea to make sure everyone knew these buildings run on clean energy.

Hydrogen is hardly a 974ft skyscraper killer.

But what's the deal with having it trucked in? That seems very inefficient.

It's my understanding that the World Trade Center project is financing the turbines and the hydrogen production equipment in addition to the fuel cells so they're paying more to get less energy? It certainly doesn't make any sense from an engineering perspective which proves it's politically driven like everything else in New York.

That's one week from today. Finally we get to see a tower crane at Tower 4.

Weren't they supposed to install it back on the 14th? I wonder what happened and what the odds are we'll actually see it installed this time?

More setbacks on this tower would have been great. This way it looks pretty boring, missing any special structure or facade to it.

I just hope for hiqh-quality cladding and the whole architectural ensemble of the new WTC to turn out great.

DIG THIS: Workers on the 64-story WTC Tower 4 have moved on to the long-awaited superstructure.


Don't look now, but that's a real Tower 4 - oops, 150 Greenwich St. - getting built at Ground Zero's southeast corner.

The photo on this page clearly shows that work on the first of Larry Silverstein's World Trade Center skyscrapers has moved from the foundation to the superstructure stage.

The boxy structures on the floor of the pit are the first stage of what will be the concrete core of the 64-story, 1.8 million square-foot tower, designed by architect Fumihiko Maki and expected to open in 2012.

Concrete for the building's basement and part of the core was poured in the past two weeks. It's unclear when structural steel will rise, but Silverstein has ordered enough for the whole job.

When completed, 150 Greenwich St. will be the new home of the Port Authority, which has committed to leasing one-third of its space. Silverstein also has an option to "require" the city to lease 600,000 square feet more.

The project isn't entirely out of the woods yet. A "soldier pile" wall built by the Port Authority to shore up the earth beneath the No. 1 line subway "box" oversteps a segment where some of the tower's footings will go on the western side.

Sources said Silverstein and the PA are working together to resolve the issue.

Matters involving security, underground vehicular access and utilities also need to be worked out.

But after years of little activity in Ground Zero, it's heartening to see Tower 4 and the PA's Freedom Tower pushing ever so slowly skyward.

how many stories down from the ground level is this? looks about 7

maybe 4-5 i would say

how many stories down from the ground level is this? looks about 7

It's only 80 feet below street level, I'm pretty sure their will be 4 basement levels (similar to all the rest of the WTC towers).

Will they connect the underground floors of tower 2, 3 and 4? It would result in a large parking garage.

Maybe it will be at street level by the end of the summer, lets cross our fingers and hope.

they said it's will be:) so I'm 99.9% sure it's going to happen. Liverstein wants this tower up asap.

nice :)

Will they connect the underground floors of tower 2, 3 and 4? It would result in a large parking garage.

Yes they will all be interconnected with two levels of shopping space around pedestrian commons underneath. It all ties into the new PATH terminal which will have its own underground connections to the WFC and to the Fulton Station subway terminal to the east.

Will they connect the underground floors of tower 2, 3 and 4? It would result in a large parking garage.

There won't be any parking because of security reasons, especially the first bombing of the WTC. There will only be vehicle access for deliveries (and I'm sure some VIP's) but there won't be any general parking. Only shops and transit terminals as mentioned elsewhere.

^^ There will, however, be a bus parking garage right beneath the PATH Terminal entrance hall. I believe that will be the only underground parking on the site.

Weren't they supposed to install a crane yesterday? Anyone could confirm if they did? I can't see it correctly on Earthcam...

earthcam is not working at the moment :(. but yesterday i thought i could see already the base of a crane.

wirednewyork.com forums are reporting that the bracings for the crane have been installed. I'm sure we'll have pictures to confirm it soon.

Well if they didn't install it today then we have to wait another 3-4 days then vc NYC will get snowed in with a foot of snow tomorrow.:lol:

I will visit this area and get some photos & videos either tomorrow or friday.

First tower crane going up:

and so it begins...
hopefully it moves faster than that other tower'across the yard. I remember high anticipation and excitement when we saw the first tower cranes 2 years ago. man how time doesn't fly!

Awesome.

There no subway under this building and its much smaller, so the speed should go pretty fast.

Should be moving a lot quicker now!

^^^^can a mod please delete this spam

whoa nelly...that one grew

This should make it to street level by September. I can't wait!

Very Exciting!

Wow, they already have a quarter floor done. That was fast, glad to see this one going up. It should be completed around the same time as Freedom.

wow, they're really fast. we've the first floor poured already and the tower crane is almost installed :cheers:

I can see lot of concrete have been poured, and they're rising quite fast.

I'm really looking forward to see this tower rise.
Strange that the smallest of the 3 Silverstein Towers is the fastest.:lol:

they are really fast. nice progress.

I don't find that strange small buildings should be built the quickest because there smaller thats how I see it. Everyone should remember tower 7 has all these other buildings beat by 4 years.

How many Tower Cranes are going to be installed for this tower? I agree about the web cam being moved some. This crane is not even visible in the Ground zero cam.

This good for WTC but there's going to be a lot of crane traffic, when the other towers start rising. And I can't wait I'll watch all the work closely.

In most places WTC7 would be a pretty impressive building. By the time the Trade Center and Goldman Sachs is done, it's going to look like the runt of the litter.
Is it too much to ask for Larry to spend $20 million add two stories to WTC4 just so I won't have to waste two mouse clicks going from supertalls to highrises.

goldman sachs is shorter the tower 7 by a foot. So its not gooing to look like a runt next to it.

Maki the architect on WTC 4 used minimalist techniques on this tower. So making it a supertall just to please us who use that loose conventional term would be out of the question.

There is a hazard now of cranes hitting each other, so till the new big boy is completed don't expect a huge amount of stuff to happen quickly on tower 4.

Gave me a chuckle there :lol:

I know theres three cranes for each WTC Tower, so does anyone have any idea when Cranes 2 and 3 will be erected for this?

New York City has revoked work permits for two cranes at the World Trade Center site after a crane part was placed in a nearby street.

The city says that contractors building one of four planned office towers at the site didn't have permission to put a crane boom down in a street before raising it. Tishman Construction was using one crane to lift a taller crane for the skyscraper under construction. It is one of three office towers being built at the government-owned site by private developer Larry Silverstein.

The cranes have been out of commission since Thursday.

Tishman spokesman John Gallagher says contractors are meeting with the city Tuesday to address crane concerns.

Are you asking me to believe a crane contractor in NY is ignoring rules? Get real.

^^ Based on some recent incidents a better question might be to they ever follow them? Of course there is a big difference between rules created by politicians and rules for safety and in many cases they are very different. :ohno:

This isn't exactly bad news. I think there should be zero tolerance for carelessness on the job on all construction sites but given this site's significance and audience size it should be about perfect. No harm, no foul...get it right already.

I agree, there should be no room for messing around with safety. :)

The first time I saw this building, I thougt it has a dent (in the upper section, left corner)
But last time I was there I stood right there on the corner, and everything seemed to be in line.
Somehow my eyes play tricks on me (no difference between pictures and standing there "live"). :nuts:
Anybody with the same problems? [sorry for going OT]

Metsfan should stop making a big deal about it.

just lik the scene at WTC1 2 years ago.

There is a hazard now of cranes hitting each other, so till the new big boy is completed don't expect a huge amount of stuff to happen quickly on tower 4.

- A

when the cranes are installed, they are designed around all the adjacent cranes! Also they are jumped and installed at different heights. Im not sure on the rules but uslally when there is more then 1 crane ona job site, they all rotate clockwise.

I'm sure Tower 4 is going to go pretty fast. It's definitely not going to be as grueling as 1WTC is. It's everything to the right of Tower 4 that's going to be lagging behind.

if the port authority is involved then they will drag everything as long as they could. Any job asscociated with them weird weird weird. But i know i will always make good money when im on a ta or pa job!!! How much money are the trade center over budget already? and hom much did it cost to erect th worlds tallest buildings LOL

Really... you sure about that one?? I mean its not the fastest ever, but these are almost exactly two years apart... nice try

^^^ Yeah their total different, you just cover a whole page reposting pics. You could have just said that without reposting. And hellrisellc what you talking about is that some kind of joke. You want to praise the Tallest building in the world go to its thread and do it.

Very simple but very elegant and nice !

I don't know where you read that the Freedom Tower is gonna cost more than the Burj Dubai:

Costs of the Burj Dubai: US$4 billions
Costs of the Freedom Tower: US$2 billions

EDIT: Sorry I just noticed you were talking about the whole complex. Forget what I said...

yeah, i read somewhere between 11 billion, omg is that true?

There's 5 building how much do you think it's would cost. The underground mall, subway, memorial, transit hub I'm amazed it doesn't cost more.

TheShark, I don't know where that place got their figures from, but it's clearly wrong. I don't know about the BD in US dollars, but I know 1WTC is costing way more than $2 billion, and the WTC as a whole is around 22 billion or something.

like the tower design :cheers:

Here's a pic from the rebuildgroundzero.org webcam from today. Nice progress so far. Should make it to street level by fall as promised.

that would be a great feat. From what I can see street level does seem a few months away.

When will they install the second crane at Tower 4?
This month?

I don't think anybody knows but it should be soon (next few months)

i can't wait to see the whole project complete...

^^ Wow! Thanks for the photos jwalas. What a difference not having to build over the PATH tracks makes. I won't be surprised if this one overtakes 1WTC by the end of the year.

I think a more correct statement would be "What a difference it makes having a project managed by a private corporation instead of a governmental agency"! :cheers:

The 1 WTC project is being managed by Silverstein not the Port Authority. So I think the PATH statement is more correct.

It doesn't matter who's doing it. Tower 4 is suppose to finish before tower 1 because it much shorter. I don't see it get over 100 feet by the end of the year. We'll have to wait and see.

Update from lowermanhattan.info,

-Foundation work including pouring concrete
-Port Authority turned over "offset" area near 1 train box; SPI now completing foundations
-Paving for Vehicular Security Center ramp on southeast corner
-Tower crane was installed in early March 2009; second crane to be installed in August 2009

So fast! :banana:

From everything I've read the Port Authority is in charge of Freedom Tower (1 WTC) and financing it while Silverstein is building and financing towers 2, 3 and 4. That's part of the reason there are so much controversy with the designing of Tower 1 because politics got in the way of good decision-making.

This tower is really moving along, nice updates!

Downtown 2020: Manhattan's Lifeline Into the Future
By Charlotte Cuthbertson
April 8, 2009

NEW YORK—Retaining Manhattan as the epicenter of the world is the work of many minds. “Downtown 2020,” a report researched and written by a team connected to the Steven L. Newman Real Estate Institute, was discussed at a forum in New York Tuesday.

The main principles of the report outlined a vision of sustainability and vibrancy that centered around critical transport solutions and completing the World Trade Center.

I don't like looking that far ahead in life, lets take it one day at a time.

Good,pictures,i love the style of this tower,the new wtc are absolutley fantastic.

I'm looking at that #1 line retaining wall, and all I can see is one small section of it that looks like it was backed off a couple of feet.
Is that all it took to keep Larry happy so he could get on with the foundation? They only recently ordered the steel for the permanent underpinning, so it should be quite a while before that wall is gone alltogether.

:righton: thank you onn

Talk about a building that's really progressing fast! Construction is proceeding so much faster than FT, it's amazing. :cheers:

It's incredible the difference in speed of 4WTC vs 1WTC. I can't get over it.

And the VSC ramp construction is very quick as well.

tower 4 doesn't have a superbase or subway or mall under it. And its just a skyscraper just like tower 7, goldman sachs, beekman tower or any other building in NY.

Great pictures Onn, I wish all pictures updates could have those great angles.

40% nearer to the ground now.

I'm really impressed, they doubled the size of the construction in about two and a half weeks. That's amazing, compared to the pace of 1WTC. Everyone should be excited about the progress here.

Yeah we get it, moving fast then tower 1. do you guys have to bring that up everytime you write here. The PA are clueless we get that, Who ever running it should be fired. Giving slivertain all the contral. The first WTC might have open earlier if the PA weren't running the show.

Any chance this will be topped out and have all its cladding by the 9/11 10th anniversary in 2011? It would be nice to have a building done at the WTC site by the time it rolls around. I know the memorial is scheduled to be done by then, and a new tower to accent it (even if only finished on the outside) would be great.

I like how this building is a bit reminiscent of the Twin Towers. When you look at/up the facade, especially on the side without the setback, it reminds me of the towers.

#7 is complete!

I'd say we're looking at least a 50% chance it could be topped out by the 10th anniversary. Probably not cladded all the way though. We gotta hope Silverstein and the Port Authority don't decide to muck everything up with more lawsuits and work stoppages though. Some of the news articles posted the last couple of days sure are pessimistic to say the least.

You know what I mean.:nuts:

Tower one should be over a 1000 feet by then. I don't really care if they finish this building by then. I'm hope when gets some more supertall built in NY. Tower ones the most important to me since they made such a big deal about.

^^ Wow! Looks like there starting the B2 level around the crane. At this rate they'll be at street level by the fourth of July! :banana:
