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.

Sorry about that! It's one of the official ones from Joe Woolhead. I just added the credits to the image. Sorry for the confusion. I do, from time to time, get in interesting places to take photos, but unfortunately this is not one of them.

And these cables will hold the glass wall in place for the rest of eternity.....it's amazing how far technology has gotten.

Update from morrongiello (Oct 13)

One more corner to go...

Already a little dated, signs of how fast things are moving now...

Port Authority Preps for More WTC Truck Traffic

October 8, 2009

Quote:

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?

vandelay · #**6208** Posted **Oct 14, 2009, 9:31 PM**

Thanks Zensteeldude

. 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.

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 · #**6210** Posted **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.

took a tour today.......Oct 14, 2009

great day!

colemonkee · #**6212** Posted **Oct 15, 2009, 12:31 AM**

Carlos is back!!!! And Leo's getting larger!!!!

JACKinBeantown · #**6213** Posted **Oct 15, 2009, 1:16 AM**

Hey Carlos! Nice shots. I would expect nothing less from you.

(And Leon's getting larger.)

No column today (Wednesday). What was M18000 doing today.

Zensteeldude · #**6215** Posted **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.

Notice the "flying beam"

PS: NYGuy, I haven't forgotten those pics, haven't had the time, yet.

wong21fr · #**6216** Posted **Oct 15, 2009, 2:30 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?

Zensteeldude knows more than anyone here what's going on at the site. And I'm sure he doesn't mind.

No problem. No rush.

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.

uaarkson · #**6219** Posted **Oct 15, 2009, 5:06 AM**

Isn't setting the pouring/setting the forms for the core going to be a huge pain in the ass with all that steel already connected? How are they going to go about that?

scalziand · #**6220** Posted **Oct 15, 2009, 6:51 AM**

^^I'd presume the same way that every other major recent office tower has done so.
