First visit to this thread for a month or so...

I'll check back in another month to play my monthly game of spot-the-difference.

Work stopped on the core to allow the steel to get far enough ahead so that both the steel and the core could rise uninterrupted.

As stated, work on the core has resumed and should be continuous from here on.

It turns out that the very strong concrete being used generates more than enough heat while curing to prevent freezing even in temps as low as 20 degrees F. Insulation is usually enough. In the heat of summer icing the mix and chiller blankets may be needed.

I remember reading somewhere that the base of this building was going to be constructed in such a way that it could withstand an explosion from a truck bomb. I'm sure they're taking every precaution they can because it's such a high profile location.

You are correct, the lobby well be protected by blast walls and the structure is redundant. This is probably the safest tower ever designed.

I like hearing how it's the safest building...but alas the Titanic was also "unsinkable."

The Titanic was a ship, and a flawed ship at that. There is considerable question as to the quality of the material used in her construction.

Nothing is "unsinkable" but some things are more unsinkable than others.

Nothing is indestructible, but some things are safer than others.

looks like east crawler crane will be moved this weekend

Looks like they are removing the big white tent from the North pool that has been there forever! :( Oh well, it was just for holding equipment used during concrete pours, and now that almost all of the concrete has been poured for the memorial and museum (at least, within a few hundred feet of the North pool), I guess they don't need it anymore.

I wouldn't be surprised if we see it pop up inside the South pool shortly, where there is still a lot of concrete pouring necessary.

Core thingy jump! Southwest corner.

Core thingy jump! Southwest corner.

Yup, the scaffolding moved up. Hopefully we'll see some core steel this weekend. And maybe a crane jump.

they should leave it in red :D like golden gate :)

West Street (southbound) has been realigned (new pavement near 1WTC), so that must be good!

no new steel for the core yet? why it's taking so long?

they should leave it in red :D like golden gate :)

It well all be encased in sheet metal column covers.

I am neither architect nor engineer, but in my non-expert view, I guess the metal (red color) are small and perhaps are not strong enough for the weight and height of this building in case of earthquake or alike.


Thx.

Enlighten us!
These are one of the thickest steel beams I have ever seen. Compare them with the workers on the site. Some beams are 3 or 4 times as wide as a human.

Earthquakes don't happen in New York.

Do they want to build another one after an hurricane ??? I'm not sure.

Earthquakes don't happen in New York.

I watched the discovery channel and analysis show they do happen as they have in the past and another major earthquake is certain to strike at one point.

On Topic:

This tower is progressing nicely. I hope we don't see more delays from the Port Authority.

i think that you saw the beams as hollow but in this case, the beams of this tower are solid-steel...and if I am wrong, someone please correct me :)

iv never been to america but theres something about new york that really attracts me to it, ground 0 should be class when finished.

any reason why its so slow at going up? is it a complicated design or something?

I think - because of both: financial problems and technical complexity.

Although the most of Manhattan locates on rocks, this area is artificial and the whole basement here was strengthened when initial WTC complex was built in 60-s. After 9/11 it took a lot of time to check and fix damage to basement walls and to ensure that the walls are able to safely serve new construction.

Also this place is very important transportation and infrastructure junction: many existed subway lines, communication, plumbing and sanitation networks had to be repaired and rebuilt after disaster to allow normal functioning of the whole downtown district before any new construction began. Unlike a lot of the new construction sites you have a huge city around here...

Technical complexity ? How do they build Taipeh 101 ? It's more complicated than this tower !

So many engineers on SSC. :|

I won't ask you how do you know that...

Anyway, I forgot another possible reason for WTC1 delay:
guess, America itself is a bit more complicated then Taiwan...
(sure I respect them both :) ).

We also had alot of government stonewalling and community disagreements on the plans. Construction couldnt start untill everyone agreed on a plan to get it done, and since there were so many different interests that wanted different things, the fact its getting built at all is a small miracle

Well, given the fact that you are not an engineer nor an expert, you should trust that the people that are engineers, that are paid for this and who's entire career depends on this building NOT falling down because of some miscalculation, are doing their jobs and know what they are doing.


Technical complexity ? How do they build Taipeh 101 ? It's more complicated than this tower !

No, it's not.
The Taipei 101 tower, other than using a completely different kind of structure, whose main support is a series of columns made out 80 mm thick steal plate and hollow, subsequently filled in with reinforced concrete.

Picture of one of the columns used for the Taipei 101 tower:
http://farm3.static.flickr.com/2779/4414522585_67acf7f7e4_o.gif

The WTC 1 tower has a main structure based on a double core of reinforced concrete each of which can stand in case the other part is damaged, that is complimented by a series of steel columns. These columns are made COMPLETELY out of steel, are the biggest columns money can buy: they were especially brought from Belgium, the only place on earth where these kind of columns are made. And in case these columns were to fail to keep the structural load that they were designed for (that is, in case of explosion given a terroristic attack like the one happened on september 11th), the core would still be able to support the load of the superstructure to be able to evacuate the building without the structure collapsing, exactly like it has happened in the past.

Lets just keep the "engineer's" statements out of this forum, or there is a possibility of making a fool of yourself.

:lol: but that is very interesting. I was unaware of that :D

:applause:

good on ya romanamerican!

I have read before (maybe in NatGeo) that old fault lines are present in the NYC area and a significant earthquake (5+ on the Richter scale) could very well happen in or near Manhattan. Maybe not tomorrow, or even in this century, but the possibilty is there.

Those diagonal beams on the base remind me of construction you see in California. I'm betting siesmic activity was considered by the engineers.

We'll be sure to let the engineers know about your non-expertise, then.

LOL.

Anyway, special thanks to all the guys (and presumably girls) who keep us updated with pics and news.

I don't comment in this thread often, so I figure I would use this chance to say "Thanks!"

Alot of Modern NJ Gold Coast High Rises and skyscrapers are built to withstand 6.0 and a few years ago a few Viaducts and Bridges were Earthquaked proofed. There are alot of small 2.0-4.0 Earthquakes each year in the NYC Metro.

An observation that perhaps someone in the know can verify?

I noticed core steel goes up before rebar or anything else is wrapped around and the concrete pour.

In the pictures the outer steel and floor supports and trusses are attached directly to the steel frame of the core then rebar and reinforced concrete catches up where the steel, floor supports etc... is totally encased in the hardened concrete of the core? Looking at London's shard the outer steel is basically bolted to the concrete core where here outer steel appears to be encased as the forms, rebar and concrete catch up? If this is the case we have hardened concrete and especially strong steel interacting with each other?

Fuck me this is going to be one tough tower!

Is my observation correct? Hopefully what I wrote makes sense...

^^

:lol::lol::lol:

Actually I agree with him, the steel columns do look a bit thin for the mass that they'll have to support. I don't think his comment is silly at all.
Also the thicker lower columns are at strange angles.
No doubt this has been calculated on a computer and various scenarios have been factored in, but to the human eye it looks weak and suspect in places.

Probably you don't realize the scale of the project, those beams are everything but thin :nuts:

I noticed the same thing on the steel ==> concrete order. In the picture below you can see quite well that only concrete has been used in the core in the first few meters. If you look at the first level however, you can look right trought the building, indicating that there are no concrete walls in the core blokking the view.

I'm a geologist. There are virtually no places on earth where faults are absent - earthquakes can happen anywhere. What matters is the likely size of earthquake, and the frequency. In places like NY, far from tectonic plate margins, significant earthquakes are likely to be very rare, and generally of small magnitude.
Even the UK gets occasional earthquakes, but when we are hit by one of the rare mag. 5 events it is national news, despite only knocking down a few house chimneys.

NY city is classed in zone 2a per UBC, the building has to be built with respect to this siesmic classing. I know the elevators have to comply to ASME seismic zone 2 in NY city.

These are all sections of columns, subtract 311 feet from the elevation in the pic to get the true elevation. Beams are in red, plates in blue. The flange of a W14x730 is 126mm thick (slightly less than 5 inches).

So is the Freedom Tower an earthquake-resistant structure? What if a magnitude-7 earthquake or even 8 strike Manhattan? I know it is unlikely in the near-future, but who knows.

As a site-wide observation, in the big hole to the E/SE I see a bunch of large rubber mats. I think they might be setting up to blow up some rock. :)

Bad luck then? ^^ I mean what if a meteorite hits Manhatten or a giant tsunami (which is possible when some volcano near Hawaii in the ocean gets active) or terrorists drops a nuke? You can't take care of every possible disaster only the most likely ones. Yes you could build the WTC to withstand an 8.0 earthquake but what's the point of that if no other building in New York is build to withstand, lets say even an 7.0 earthquake.

I have read the past few pages of this thread and will just say this and then refrain from further comment. If you do not have updates, knowledgeable opinion, pictures, articles or comments directly related to this building. Why post? Please think about this as people who are actually interested in the evolution and construction of this building don't want to read about your 6th grade opinion on steel columns or load bearing conjectures.

Regarding earthquake, tsunami, ebola outbreak, hang nails or whatever else you crack heads are going to talk about, it isn't relevant. Go make a thread in skybar about it or rent the movie "2012".

Thank you have a nice day.

I asked a question about the Freedom Tower, not asking the same questions all over again, "Wow, great updates", "nice" etc. if you don't want more comments then why reply?.

^It was more so a general comment, especially to some of the knuckle heads in the previous pages. Though I find it interesting you edited your comment to make it more specific in light of my remark. I think that speaks for itself.

So where is your update, pictures or news. Look you can't bitch about something and do what your bitching about at the sametime doesn't make much sense doesn't it. The weather is good today, best it's been in months.

The south crane is jumping.

So is the Freedom Tower an earthquake-resistant structure? What if a magnitude-7 earthquake or even 8 strike Manhattan? I know it is unlikely in the near-future, but who knows.

The inteligent answer to you question is: Yes, Tower One is designed to withstand the strongest earthquake predicted to hit the NYC area in the next 100 years.

The odds of a 7 or 8 hitting New York in the next 10,000 years is . . . . . you will win the Power Ball lottery 6 times before that happens.

you do know where hawaii is, right? and if you are talking about la palma in the canary islands, that's not gonna happen. incorrect assumptions were made about the risk of flank failure and a resulting tsunami. and obviously it received inappropriate attention from the media.

The earthcam won't show a good view soon. :P What's the link to the other webcams?

dunno why but i dont like the number of this page ...
btw nice update, first i though it was the core ! This tower will be thiner than i though but i like it !

hmmm...

Does anyone know the dimensions of the tower now, and how close to a cube it is? because it looks like it is about as high as it is wide.:)

Excellence progress. :banana:

To look at the latest picture, it's hard to believe how intricate the construction is below grade level. One would never know looking at the site today.

hmmm...

It nearly is a perfect 200 ft cube. I think height wise it's just shy of 200'. Probably 190-195' high. The floor is 200'x 200'.

^^when America built the empire state building it was the great depression...now as the freedom tower is taking up shape America is experiencing the same financial crisis...

Of the USA's major cities, ISTR that the ones in Texas are at the least risk from earthquakes, also the MStP area. Chicago is at relatively minor risk and has a 3 to 4 or so shaking every few years (one hit them a couple of weeks ago). When the next 'big one' hits the New Madrid zone, I would fully expect some tall-building sway and minor damage to smaller buildings (some cracked walls/foundations, fallen chimneys, tipped bookshelves, etc) in Chicago. Also, taller buildings are much more earthquake-worthy than shorter ones.

The cities at greatest risk are all of the ones along the west coast, plus Memphis, TN and Saint Louis, MO.

Mike

any news what's up with the long delayed quarterly report?

damn, I miss it, I want to know for example how far they are with the corridor under West Street, just noticed that they moved the street lines in north-south direction

btw: the white tent in the north pool is gone :-)

Steel trucks lining up for off-loading this morning! Hopefully this is the beginning of weekly growth!

Is there any possibility the high def cam will be angled up as the construction rises?

I've got a question to Zen or anybody else who could answer this: when will the core start to change shape?

I would expect them to put up the remaining corner node parts before fully standard floors start going in.

As for the cam, its main purpose is to show the construction of the memorial museum and plaza. I guess they could raise it a few degrees or even better, set up a dedicated 1WTC cam, but I doubt Earthcam is willing to spend that much. After all, 1WTC is also visible from the street, the memorial is not.

I hope this question doesn't sounds childish or naive (and I did re-check all the posts for the past 7 or 8 pages) ... but does anyone know the actual Floor Count by now? :?

The first of the office section core steel is in. It looks like three floors at one time.

Floor 20 now.

The first of the office section core steel is in. It looks like three floors at one time.

I was thinking the same thing earlier, when the core columns looked big enough for three floors, but now that they have the beams in place it's definitely just two floors at a time. The columns rise a bit further to the connection points but just a few feet.

Hey, we can see the yellow Subway Box again....hehe

I've got a question to Zen or anybody else who could answer this: when will the core start to change shape?



I would expect them to put up the remaining corner node parts before fully standard floors start going in.

The core has already changed shape, though the walls are not in yet. It is much smaller at the 20th floor than at the 3rd floor. It won't take on an octagonal shape untell somewhere around the 65th floor.

The construction of the 21st & 22nd floors well look almost exactly like the 20th with the corner node sections going in last.

I hope this question doesn't sounds childish or naive (and I did re-check all the posts for the past 7 or 8 pages) ... but does anyone know the actual Floor Count by now? :?

The actual count is seven full floors and four mechanical mezzanines.

I was thinking the same thing earlier, when the core columns looked big enough for three floors, but now that they have the beams in place it's definitely just two floors at a time. The columns rise a bit further to the connection points but just a few feet.

Yea, the column splices are 3 to 4 feet above the floor beam conections, less moment stress there.

The new side beams on the South side do not appear to be red coated.

that is true..but they are up finally:banana::banana::banana::banana::banana::banana::banana:

Yeah I'm happy things are moving again. the best view has to be from the FDR after the Battery Park Underpass. I hadn't seen it from there because I usually take the Brooklyn Bridge.

very clear up date picture..

Uh oh soon its gonna pass the Earth Cam then i wont be able to see it being built :(

I dont know if anyone has asked this question, but when are they going to start with the cladding? If I'm not wrong, some towers began when they were almost completed and some of them, when they were between 10 to 40 stories high.

I see that the office floors will start to rise now

Anybody know what today is? The eight and a half year anniversary. That in and of itself isn't significant, but anyone who has been following the progress on the memorial knows that construction really began (except for a few columns that went up a couple days earlier) on the 7 year anniversary (September 11th, 2008), and it was announced that the memorial would be open in exactly 3 years. Today is the halfway mark. It's been exactly a year and a half and we have exactly a year and a half to go.

So, it's up to you to judge for yourself whether you think they're on schedule... whether or not it looks like half of the construction is done. In just a year and a half, they've made HUGE progress on the memorial, nearly all of the steel and concrete is in place. I'm hoping that exactly 6 months from now, they will have 100% of the steel and concrete in place, which would leave them a full year to do the final landscaping and tree planting and whatnot.

I would vote "No" to moving T3 to T2's spot. Let's hold out for T2 to be built. NYC is filled with old office towers that will be unsuitable in the coming years. Their will be demand for newer "green" office space eventually. NY's vacancy rate is around 10 or 11%. Most cities would kill for a rate like that.

the spire almost 100m long...

I'd rather see Two tower 1's then to see tower 3 next to this. Oh that pictures a lil off the ESB isn't to the left that should be Jersey we're looking at.

I have to admit it kinda takes the amazing height of the 1 wtc away when you put them so close

the spire almost 100m long...

And the antenna on the original 1 WTC was almost the same height, it just didn't count. Who really even cares?

anybody know how big a boom in a big white now? looks like they extended it, looks huge.

80 feet of boom and 190 feet of luffing jib

Duetche bank is now less than 20 floors high. Why don't they just implode the ramainder and get it over with?

I wouldn't worry too much. He/She just likes to get on daily and make multiple inane comments.

It may have someting to do with the fact that it is 5 feet from the nearest street and has buildings within 2 feet of it on 2 sides.

I think it looks best in the pic without tower 2. Tower 2 is way too flashy for not being the tallest building on the site and it is screaming look at me architecturally. All of the other buildings have flat roofs which go with the the old towers theme. The focus should be on tower one and how its New York's new tallest building they have ever had and is one of the tallest towers in the world. Tower 2 needs to be a little more anonymous while still being and extremely nice building. Call me crazy but thats just what I think.

crane parts for 2nd memorial crane has arrived

80 feet of boom and 190 feet of luffing jib

I thought it was 80 and 290? It sure looks that long.

I'm sure you say the same when playing mikados or jenga :D

Just look back at the Singer building.

I wish Singer was still there, but had it stayed and the events of 9/11 transpired I'm not sure it would have survived.

How about we re-build Singer at the DB site instead of 5 WTC? :p

I second this. Now all we need to do is get a substantial following and find the blueprints or revive Ernest Flagg. :P

On topic: It's pouring out. I doubt we'll be seeing any steel go up today.

New pics of the preliminary office flooring are up here: http://www.panynj.gov/wtcprogress/index.html

You never know. If nothing happens in the pit where the proposed 200 and 175 Greenwich street towers are meant to be started, there is room for them there. Time will tell.

You never know. If nothing happens in the pit where the proposed 200 and 175 Greenwich street towers are meant to be started, there is room for them there. Time will tell.If they had enough money and company's that would want to move in they wouldn't build the twin towers again they would build 200 greenwich and 150 greenwich :bash:

I know when these towers are up they will focus attention but looking at the panorama pic #13342 those two original footprint memorials attract my attention right now. Those towers were proud and well sited on the superblock. Because current thinking is for security will new through streets really be open roadways so close to the new towers ? If not......the former layout was OK. I know we have moved on so I accept what's going into the site. But you can see everything including the new WTC 1 is squeezed around the former footprints.

ok so by that picture in the top post on this page, does that mean 2wtc is not going to be built? :cry: :badnews:

and yes the singer building should have never been demolished, even though that was more than 40 years ago it shouldnt have happened :ohno:

That would be seriously amazing, if some sort of campaign could be organized... Is there any precedent for that, anywhere? Has a building, once demolished, ever been replicated, years later? I would absolutely join a "Rebuild the Singer Building" campaign... especially for the Singer.


ok so by that picture in the top post on this page, does that mean 2wtc is not going to be built? :cry:

It most definitely does not.

Guys.....well anyone ? rebuild the Singer Bldg. ? I don't see that happening. Don't you realise the world works on dollars and cents.....OK usually just the dollars......can't figure what you guys do with all those little pennies? ..anyway, In Europe many structures from whenever were recreated after WWII many cities were almost totally destroyed yet if you visit now you see replica buildings built in the 1950's....or 60's....some great and often shallow copies of what was once grand. Buildings like the Singer if still around now become either apartments or boutique offices.....so the maximum dollar return only happens when a building is saved from destruction because it is on the National Trust.....like who would demolish the ESB or Chrysler........even though Hollywood does regularly ?

Singer Building had impractical office space, that is why it was knocked down. It was a nice building, yes.

No more "rebuild the twin towers" BS here, please! That discussion is over - get over it!

Yep, that's what it was about when it came down.....obsolete office space....even here in Melbourne we had 'almost' the worlds tallest building back in 1880's and now a 5 story office with shops at street level have replaced something that can never be replaced.....It had thick load bearing walls....and a deep hydraulic shaft that pushed the lifts to the top !............Now it would be a tourist attraction or at least upmarket boutique offices.The world moves on and we keep replacing. New York is the prime example....a city that's never finished....Just let's hope developers and architects keep imagination and wonder as part of the equation.....in the 60's efficiency seemed to rule ?

Nice to see the office floors have begun.
If 2 & 3 WTC are not to be built, then a second 1 WTC should be !

This whole project and all the circumstances surrounding it must be almost as painful as that day in September.
I don't see why the federal government hasn't stepped in to straighten this mess up.
This project is much bigger than the city of New York, and must be an embarrassment to all Americans.

I can imagine that Bin Laudim is in his cave and still laughing.
(that is, if he had something to do with it...)

wow is this going to be like the tallest in america then

The Twins should be built in GZ!, because when they go up in NJ it will show new york's failure to rebuild itself, the FT plan now is a American Disgrace!

That's one of the best descriptions I've read yet about this entire fiasco. It took a Canadian who accurately describe what's happening in NYC and he hit the nail on the head.

Yeah build crap copies of our buildings in Jersey won't make Jersey any better, it's still gonna sick over there and they'll still be faking like their New Yorkers. This is the real world buddy remember that when you talk BS about something that's never going to happen.
Msradell and mclancer that's the job of the state government you don't like what our city and state doing down there writing your governor about. Believe me ppl in NYC aren't embarrassed in the less bit.

Says YOU

The Twin Towers were not Crap, they symbolized Americas financial strength

Don't try to flip my words buddy it's not going to work. I said crap copies of our buildings, where did you get twin towers from. I could be talking about any building in the city. And you mean Lower Manhattan financial strength. Midtown's number one in that department even when the WTC was around.

Hopefully some pictures will get this thread back on topic......

I see that the "wind frame" design of the office floors allowed them to put up the next section of corner node on the SW . (The mechanical floors are a braced wind frame)

The perimeter steel resists almost all of the wind load and about half of the gravity load (the core takes the rest).

Wow, so have they completed the bottom half? and now there doing the actually building?

^^ If the tower were to be 374 feet high the bottom half would be finished.

The base is finished, as far as structure goes, and now the office floors rise.

Why only one tower? Are they gonna built the second one later? Two of these will look nice. Maybe in another ten years will see the second one.One world trade center wont be twins

no just the 1 tower

so very true.

The Twins are gone, deal with it.

who is that aimed at?

All the "rebuild the Twins" folks. Nothing 20 years of therapy can't fix.

Remember the past, live in the present, build the future.

I meant the base :nuts:

I thought you did, I just wanted to be crystal clear.:)

true, the twins were very ugly to look at (white rectangles, hard to believe they were tallest in the world at one point :P) but that doesnt undermine the fact that thousands died on that day they collapsed. may they rest in peace

what are you chatting about? loool
im sure people are over the twin towers lol its just the deaths people may not be over!

maybe the people that want it rebuilt are under some cazy notion it will all be better and everything would be forgotten, well sorry something that big just doesnt go away

what are you chatting about? loool
im sure people are over the twin towers lol its just the deaths people may not be over!

I wish that were true, but there is an entire group of people out there who actually believe that they can influence Silverstein and the PA to destroy and remove what has already been built at the site in order to make way for these abortions:

what are you chatting about? loool

There are a large number of people who can't separate the two.

1960's architecture isn't going to work in 2010's. Wishing I could have seen the original towers. I like the design of the site as it is now. They need to go overtime on this bitch.

maybe the people that want it rebuilt are under some cazy notion it will all be better and everything would be forgotten, well sorry something that big just doesnt go away

i doubt they want that because it would be extremely disrespectful to all the people who lost their lifes and the people who lost their love ones, but if that is what they want then they are selfishly unfortfull in my opinion.

Original Site wasn't built all at once...
1 WTC: 1966–1972
2 WTC: 1966–1973
3 WTC: 1980-1981
4, 5, & 6 WTC: 1975-1979

4, 5, & 6 WTC: 1975-1979
7 WTC: 1985-1987So they built Wtc 4 5 & 6 before 3? :nuts:

looks like it acording to iamxeddiex but i dont no for sure but it would all depend on the funding at the time for example

Number 3 was built after 4,5 and 6. #3 was the hotel built next to #2 south of #1.

http://911research.wtc7.net/mirrors/guardian2/wtc/site-plan.jpg

The plaza building probably weren't named 4,5 and 6 WTC at the time. I don't know..or maybe 3 WTC was in the original plans but they decided to build it later for some reason

according to Wikipedia...

They are building WTC 4 before 2 and 3.

#3 was built after 4,5 and 6 due to being privately funded. #7 was not in the origonal WTC plan.

The court better rule on the site regarding construction, I think we've had our fair share of bickering by now. Tower 3 needs to be built.

Great to see Freedom coming along!

That explains it. Although I find 3 and 7 WTC to be different from the rest of the complex itself..

Well according to The associated press Silverstien and TPA are dragging it on some more despite the deadline :bash:
NEW YORK — Both sides negotiating a new completion plan for the World Trade Center site say they're continuing to talk despite a deadline.

Developer Larry Silverstein and the Port Authority of New York and New Jersey said in a statement Friday that they are continuing to negotiate.

Both sides say they've given an update to the arbitration panel that set Friday's deadline.

They say that after "substantial discussions," they "have made progress toward resolving the issues surrounding the eastern portion of the World Trade Center site."

The building of planned towers at that part of the site has stalled in a dispute over financing. Silverstein wants more public money to build the towers, but the authority says it's better to delay construction on two of the towers until the real estate market improves.

Hi, it is a bit of topic but maybe i can help with you discussion.

I have a link here with all the original 1963 World Trade Center Master-plan, where 5WTC actually was the hotel and 3WTC was just an office building.
And 6 and 5WTC where like one big building.

http://911research.wtc7.net/wtc/evidence/masterplan/index.html

I guess they just came up with a better plan and new design for the WTC hotel. Because it was originally called the Vista hotel owned by the PA like the rest of the complex, but later (late 80's or mid 90's) sold to the Marriott Hotel group.

so i have a question:

in the new world trade complex, where would the sixth building go? it goes from 5 (jp morgan chase) to 7 (7wtc). would the goldman sachs take the honor of 6wtc?

Hopefully some pictures will get this thread back on topic......

Nice updates, many thanks! :banana: :cheers:

I hope the construction process will accelerate. But its difficult to bring all the construction material on stie in the middle of a big city. There is not so much space on site with all the other construction sites nearby.

according to Wikipedia...

They are building WTC 4 before 2 and 3.

Yes they are :nuts:

I recall that owns all the land on which the previous which was a newly built complex of the World Trade Center, the Port Authority of New York & New Jersey since the early '60. The current developer Larry Silverstein is the sole tenant of the former World Trade Center complex, and now land in lower Manhattan. Another tenant is the Westfield Group, which is leased areas below street level or ex Mall. So just three people / companies having rights to land can not get along ... that is, the dispute has no end. Fortunately, the power of New York and the Lower Manhattan Development Corporation gave the delivery person "concerned" at the time because it speaks to the conflict in the whole city is suffering and its citizens. In the absence of compromise, the consequences will be disastrous.
In my opinion, even better, that suspended construction WTC2 and WTC3 the simple reason that if the One World Trade Center will be the dominant object in Lower Manhattan is in the vicinity should not be in places like the height of WTC1, and even slightly lower than the object dominant. In my opinion, LMDC should consider spatial development plan for this place and take into account the fact that WTC1 (not) be the dominant object in Manhattan. I am not here to make this part of the site has been built up, on the contrary, but as I build it with his head. Had WTC2 and WTC3 built their height coincide or differ very little up to WTC1. Currently, an object which is not dominant, but on the contrary is currently being built "four". I recall what he looked like the skyline of Lower Manhattan before 9 / 11. Twin Towers were the objects of the parent building and none dared to approach the height of the Twin Towers. A similar situation is in Upper Manhattan, where, surrounded by the Empire State Building is not equal to those of his building height.

I see that the "wind frame" design of the office floors allowed them to put up the next section of corner node on the SW . (The mechanical floors are a braced wind frame)

The perimeter steel resists almost all of the wind load and about half of the gravity load (the core takes the rest).


Zen,

Would you mind talking a little bit more about "wind frame" design vs. "braced wind frame?" I know for some that might seem very obvious/elementary, but I'd really appreciate it if you could explain it a bit more.

Thanks bud!

Looks like they started installing columns through the electrical station at the very southern end of the memorial.

this is my first post. i believe i updated this correctly. I used to work in the cranes that operated inside the memorial pit when construction first began

someone has informed me that i stole someone else's work. i am sorry and i will delete if asked:ohno:

wow.. im glad to see that its growing up.. i went there 4 months ago and it was almost in the second floor Unless I\'m mistaken.. (not including the hall). congrats.

Wow, we have a long long long way to go :ohno:

Well now that the foundations have been laid and the base of this tower, at least the "bones" of it anyway are done, this thing is going to shoot for the sky rather fast, and be done before we know it, and it will be spectacular rather soon. Remember it took a while for the originals to take affect, so why all the fuss?

Are they going to lift up the web cam soon? I can't see a quarter of the top of the tower.

If you're talking about the earthcam, it's for the Memorial, not 1 WTC.

Once the tower is out of view, we can only rely on photographers. But it's interesting to see the memorial completed too.

All a wind frame is is how the beams are connected to the columns. They are connected with both a shear and moment connections. The braced wind frame just has diagonals in it.

well,it's a 541m tall building,what do you expect?..remember that the original towers took a few years to be built until the entire project was finished,not to mention that this is obviously a reconstruction of world trade center..:)

^^^ took ten year to finish the twin towers. Hmmm the other towers was started much later. as long as it gets finish I don't care how long it takes.

Edit: Already brought to his attention.

Though it's a little bit hard to follow and a little more technical than I wanted here is a good pick of shear and moment connections.

Thanks Zen. I'd been wondering about those connections. They can't be more than 20 times as strong as the originals.

I will be curious to see where the additional crane is going to end up. I was surprised last time when it ended up in between the memorial and the track. I don't see where it can go on the tower. My guess is that it will end up in the gap between Tower 1 and the structures to the south east.

It's gonna be in te gap a little bit more south from the crane that's already there...

Thank you for the pictures! Its going to get hard for us to find good pics as the earth cam stays focused on the memorial site. Keep it up!:applause:

very clear up date...

I love steel structures!

You can see the sheer scale of this building when you notice the two people in the uppermost base floor.

damn fast, thats the speed we need :nuts:

New York it seems fine - but not to London. :)

NY has out paced London for over 200 years... the shard might be going up quickly, but London will never experience overall growth at a rate that would bring it anywhere near NY. How many towers are going up in NY right now? I can think of at least 5 that are skyscrapers or taller. There are 6 super-talls that are approved or are in preparation, and there are 4 more regular skyscrapers approved/in preparation. NYC is now has more super-tall projects than skyscraper projects! London has what, Canada Square as its next tallest? Its only 50 stories! NY alone literally has 56 buildings 50 floors or taller. Get off your high horse. People in the US like the Shard, we think its great that its going up fast.

Show some camaraderie for the architecture of both cities instead of being a jerk.

Both cities are great but in highrises and supertalls London doesn't stand a chance. That's just how it is

This gonna be the best tower of New-York!

It just struck me. At around 8oo feet up, this building is going to be an equilateral octagon. I can't believe that has not occurred to me before.

:lol:I was there for the first time today i took pictures from that same place:cheers:

:lol: yeah, i saw a few people taking pictures too, i was there around 1:30 - 2:00

BeanHead,

You are the best! Those are exactly the shots I was hoping to see today. Especially the closeup of the corner beam showing how the top of it begins it's division into two. Awesome!

Thank you!

glad you enjoyed them!

Great News Folks! The answers from www.wtcprogress.com regarding One World Trade Center are now on there. According to Lynda Tollner, program director in the World Trade Center Construction Department with design and construction responsibilities for One World Trade Center, she projects the Tower will reach between the 55th and 60 Floors by the end of 2010 and it will have a total of 105 Floors. So feel free to examine some of the questions and answers.

Then it should be almost the height of 7WTC by the end of the year.

glad you enjoyed them!Yea me too! :nuts:

2nd crane boom is now attached to a crane :). I though they will wait until daylight to do this kind if things. I guess not :)

Should move quickly up now. :cheers:

Will the core start rising above the steel now? Or, will the core and steel be constructed successively, one floor at a time rather?

Just interested to know, seeing as London Bridge Tower's core shot up 20 floors and then the steelwork was erected...

^ The core will always be slightly below the steel.

Why is the new steel a different colour ?

Different construction methods and different scheduling.

1WTC initially sounded (from the outside) like it would be core-first, with everything apparently waiting for the core that was over the path tracks, which was very tricky / slow to start. Then the steel just went up without the core anyway, and the core stopped to wait for the steel to go ahead. It will proceed from here with steel first and core following - so the latest wait on the core kind of makes sense to allow the steel to get up to the standard floors where everything can then get into a nice rhythm.

They are on the standard (although they change shape as they go up) floors now, and the steel looks to be going up two floors at a time. LBT is doing that too - it's probably the optimal point in terms of how much gets done at once, and convenient size of steel to lift and work with.


At LBT, some steel actually went up first while the base of the core and the slipform rig got started. Then the core went up and the steel is now following as soon as the core was cured to attach to. The core is now stopped (upwards) to let the steel catch up but also to build the core and basements downwards. So everything (concrete and steel) is still proceeding at once but in different areas. The whole core that we see at LBT is sitting on steel columns set into the piles, while they dig out the basement and build the lower levels of the core, above/around the underground train lines that I believe are down there. All that is now happening out of our sight, where we saw it happen in the open as the first stage with 1WTC. I don't know if the LBT core could have gone up to full height without the basement levels being completed - quite possibly not.

Well it just seems, to me, to add to the confusion on the "floor 20" thing.

Now we can see the standard floors going up, scaling crudely from posted photos it looks like about 12 standard floors equivalent in the base - about 15ft per floor which roughly fits with overall height/floors. 20 floors might add up right if you started counting from the bottom of the basement - I thought that they might be doing that for some reason.

According to these answers though, it's based on the 200ft above ground and a typical 10ft floor height. That just doesn't make sense looking at the actual standard floors in the photos. It would also be extremely agressive (maybe impossible) in a skyscraper.

I don't believe 10ft can be the floor height in this building, equally I don't understand how a program director for the building doesn't know or can't find out (for a public response) the real floor height. Makes no sense to me. :dunno:

The construction photos of this building give me the impression of solidity and permanence - as if the form is saying, "this building will still be standing here come doomsday!"

LBT's construction, on the other hand, evokes a somewhat more delicate "leaping for the sky with poise" image.

Given the setting of each, and the symbolic role this building occupies as part of the 9/11 legacy, I think these differences make perfect sense.

I'm finding both buildings fascinating.

Why is the new steel a different colour ?

Different types of fireproofing. The lower levels use a red fireproof paint that foams up when heated. The upper floors will have standard spray-on fireproofing which is applied after the steel is erected.

What is the height of the building without the spire? I heard something around the 1300 foot range.

Wikipedia says the roof height is 417m (1370ft)

Does anyone know what they placed over this one part on 1WTC?

The office floor height is 13 feet 4 inches.

It'll be 1,368 feet to the top of the parapet, same hight as the First Tower One's roof.

Wikipedia says the roof height is 417m (1370ft)

Wikipedia is wrong, there's a shock .:lol: The roof hight is 1,334' 8".

Will the lower floors have more fire protection then the higher floors?

No, the entire building well have the same, high standard, of fire protection.

Great pics Momo1435 !
