In the picture posted earlier, does anyone know what accounts for the protrusions in this column?

Those are anchor points for the cable net wall above the entrance. Just like #7 there well be a glass wall above the entrances supported by highly tensioned steel cables. The pic of the east plaza at the bottom of the last page shows the anchors, before the cement was poured, for the vertical cables. There are also anchor points on the beams above the entrances.

There are also anchor points for the stainless steel plates that well suround the entrance. (They are 2 inches thick by 3 feet wide)

The columns on the east and west sides do not have them becouse the cables are anchored into the blast wall.

PS: THe pic is of the north side.

Port Authority Preps for More WTC Truck Traffic

October 8, 2009

Port Authority work is continuing on the fast track

Truck traffic through the World Trade Center (WTC) site’s west side is ramping up, according to the Port Authority. The agency told Community Board 1 this week that it is preparing new access and egress roads through the northwest corner of the site, as steel installation continues at 1 World Trade Center.

The update was delivered by Quentin Braithwaite, the Port Authority’s assistant director of WTC construction. He told members of the board and the public that 12 of the tower’s 24 jumbo-steel columns are now in place around the perimeter, forming the base from which its 102 stories will rise. Those 70-ton beams are to be complete by late November.

Around the tower’s base, the steel and concrete plaza is being built, and will soon accommodate trucks delivering materials for 1 WTC. A plan to extend the Vesey Street Pedestrian Bridge to the east side of Washington Street is being finalized -- and would mean that by late March 2010, trucks will be able to drive under the bridge and onto 1 WTC’s plaza without disrupting pedestrian flow. They would then exit through a new gate to be built at West Street at Fulton.

Man, I can't wait for that final pour of the plaza in the NW corner. When that is done that should be it for the ground level concrete wise (I think) and all the action moves to the tower.

Anyone know when the Fulton Street tunnel will be covered?

Thanks Zensteeldude :worship: . I was going to call you out specifically to answer my question, but I didn't want to be presumptuous. I think this tower is really going to impress people after it's been completed for a while. People might say it's boring now, but it's all in the details.

Anyone know when the Fulton Street tunnel will be covered?

Not anytime soon. Visibly, the tunnel hasn't reached the World Financial Center, and it's probably, or no less than 40% excavated.

I don't like the idea of having reucks trot all over the plaza, as it leaves nasty tire marks upon completion, so I hope there will be a different method of doing this.

Zensteeldude

Oct 14, 2009, 11:29 PM

They solved the truck problem by not driving trucks on the plaza level. The slab that can be seen now is the structural slab, that is what the trucks well be driving on. The plaza level is 6 feet above the structural slab.

Zensteeldude

Oct 15, 2009, 2:17 AM

Well, from the looks of it the 18000 put up the 3rd column from the west on the north side and the beam above the north entrance. By the way, those are the toughest lifts the 18000 has to make, everything else is closer and/ or lighter.

Zensteeldude

Oct 15, 2009, 2:47 AM

Zensteeldude,

Don't they have to complete the pour along the NW corner in order to provide the lateral strength for the NW columns? If so, does that mean that we have to wait for another pour before seeing the rest of the base columns go up?

The concrete encasement of the columns and the B2 and B1 slabs below the plaza/lobby should be more than enough lateral stability for the jumbos to go up.

The previous lift of perimeter columns is also shorter on the north side thus reducing the unbraced hight. But of course that makes the current lift of jumbo columns longer and thus heaver. The media totally missed the fact that one of the largest, heaviest perimeter column went up today with no fan fair.

The loads the columns and slabs are placed under today are a drop in the bucket compared to the loads they well support when the tower is toped out.

PS: I have 3 kids, 7, 5 and 6 months, believe me when I say, there are no stupid questions. And I am happy to answer any questions I can.

I don't think that there is anything special here, the outer structure is always connected to the core.

Actually, from the lobby to the first office floor, it counts as floors 1-19(different ceiling height must be the culprit), and there are only 5 mechanical floors.

The Shanghai WFC's exterior was connected to the core(only that the concrete core rose faster than the building itself, vice versa for this project), however this building requires that the steel rises faster than the concrete. I was a bit skeptical about this last year, but it all makes sense now.

There are no floors 7 through 19 and they are erecting the 4th floor on the east side so we'll see office floors before spring.

The forms are modular and there really aren't that many beams to work around. It's also made simpler because the floor slab is actually keyed right into the core wall.

Another column this morning, the 19th of the 24.

NYguy, do you have a schematic showing why the column installed yesterday is slightly tilted? I know it has to do w/ the rail system, but a schematic showing the column and the base column installed long ago on which yesterday's column was attached and the relative to the location of the tracks will be instructive. This anomaly will be the source of questions for years to come and it will be great to have an instructive illustration.

Would you settle for a pic of the north side from foundations to the 4th floor ?

http://farm3.static.flickr.com/2521/4014781985_ac6cf14f7b_o.jpg

And maybe a plan view too. The column in question is the third one in from the left near the top. The curved dotted lines are the PATH clearance envelope.

Ah, my eye wasn't tricking me with the second picture. The northeast corner of the tower was slightly less chamfered than the other three corners, but I believe that's where the diagonal column is. It manages to come out to a perfect tapering when at street level, so it's hardly noticeable. And the North core...it's amazing that they managed to span the concrete over the PATH tracks without reducing it's payload. This tower never ceases to amaze me.

Thanks. It's nice to have a little clarity on just what's going on with the top of this tower. The ring will give an open "dome-like" appearance with the spire being the final piece of the puzzle.

Oct 16, 2009, 7:39 AM

Zen, thanks for the schematics, much appreciated. I see that the "base column" is in fact vertical, but offset due to the tunnel, and then the tilted column making up for the offset. I was trying to visualize if the "base column" was also tilted but see that is not the case.

I curious to know if the tilted column on the north side will be visible through the eventually fancy prismatic glass wall or if cleverly hidden so that everything appears symmetric for each side.

BStyles

I hope not. That will ruin the symmetry of the tower, especially when it's backlit at night.

Canadate - excellent close in shot of all the big steel. Thanks. And iamtal, thanks for indirectly alerting us that the hi-def earthcam is back!

Also, I noticed that they are building some kind of a new roof for the PATH station, Maybe first step before building the memorial plaza above the station.

They are actually demolishing more of the roof, to the North of the part they took off a few months ago.

Wow, I think of skyscrapers as being a metal frame that is mostly empty inside, but this thing packed so tight with crossbeams and concrete that it's had to visualize where the people will fit! I've seen skyscrapers go up before and they've appeared more loose and open.

Did the first WTC look like this?

I realize that more structural components are necessary in a supertall skyscraper due to weight increases with scale, especially one that needs to be able to withstand a terrorist attack. It's just incredible to think about how much material is being pumped into such a small amount of real estate.

Impressive progress. I love it!

The structure of the beams now visible is reminiscent of the original twins to a degree. (I mean the way they split from one large to three smaller beams. The old towers went into two, but it still reminds me of them.)

Wow. Those coloumn 'trees' in the center heavily remind me of the old twins design/construction site! All the progress being made is just wonderful to look at. Will those beams be covered by concrete in the future?

Wow, this is the first shot where I really feel it looks like a building. Can't wait to see this one rise above Manhattan! Definately the most exciting project in the Americas currently, if not the world. Keeping a close eye on it up here in Canada.

Remember that this portion that we see under construction is the "bunker" upon which the occupied floors will stand. So, it's going to look a little chunky until we start seeing the office floorplates go up in Q1 of 2010.

But usually there's some kind of atrium or impressive entryway for a high-profile building, and I'm having a hard time visualizing where that would be when this section of the building is chock full of beams and cement. I'm not complaining, just curious.

There is a drawing that refers to floor 110 but I have only been able to find 109 numbered floors. That 109 includes the communications rings above the roof.

The actual floor count is around 92, not counting the basement levels. With those it's 97.

OK, Thanks.:)

The "bunker" is a myth invented by the media. Tower One is designed to withstand 2 things the Twins never were. One, a 5.0 earth quake and two, a force 4+ hurricane. Either one of these well put more stress on the tower than terror.

The blast wall, added well after the tower design was finished, extends up to the underside of the third floor. It's there to protect the lobby from truck bombs.

The core is so large in the base because there are several MEP shafts that terminate at the lower mechanical floors. The largest of these shafts is an air vent for the PATH tunnel under the Hudson. (There is another one built into the Memorial for the in-bound tunnel.)

Like a tree trunk, the core well get smaller as it gets higher and take on an octagonal shape, mirroring the outer walls.

The pic is not sideways it's drawn that way to convey the principle of cantilever tower construction. Gravity is the weakest force acting on the tower.

Ugh, now one part of the tower is moving faster than the other again:haha: . At least the steel cage is up, nothing to worry about.

@Pizutti: This part of the building, when completed, will be clad in glass prisms, and just like the original towers, will have underground passageways that lead to the Mall, WFC, PATH Station, and Fulton Street Transit Center via escalator. The lobby is pretty massive.

Oh, and it's about time the earthcam is up!

@Zensteeldude: The shafts in the memorial and the core of this tower are for loading supplies from the PATH tracks? Or are they for emergency evacuation purposes?

That will be interesting to see.

They are to vent the Tunnels under the Hudson. A train in such a small tunnel acts like a piston, the air has to go somewhere.

Oh, and it's prismatic glass panels, not glass prisms. And some of them wont even be glass, they'll be blast resistant plastic. (nothing is blast proof)

PORT AUTHORITY BOARD APPROVES SEVERAL ITEMS TO ENSURE WORLD TRADE CENTER PUBLIC PROJECTS MOVE FORWARD

Date: Oct 22, 2009

In addition, following a request from New York Governor David A. Paterson in August, the Board also authorized $20 million in planning and design money to allow various consultants to modify certain components of the WTC Hub to permit the Port Authority to complete the construction of the public components of the WTC site independent of construction of Towers 2, 3 and 4.

The development of this option also will require certain modifications of various aspects of One World Trade Center, the Vehicular Security Center and other infrastructure. The design modifications will not compromise the integrity of the design of any of the projects.

Wow I am impressed. They've really ramped up the construction. It's starting to looking a building now. Thanks for all the updates!

I have seen supertalls in the construcion phase where the core rises above the floors, but why isn't this one doing it?

wong21fr

Oct 23, 2009, 1:03 AM

^Something about New York City construction guidelines. The core can't rise above the rest of the building during construction.

Isn't it a union issue?

Yeah, I should have mentioned the mechanical elements. I didn't realize that 1 WTC also had ventilation tunnels for the PATH, that's pretty interesting.

However, with blast walls and blast resistant paneling, the description "bunker" does work. While it's not a true bunker the additional blast resistant elements certainly earn a better moniker than "force protection". Bunker sounds better.
