That transfer beam should be this think marked by the red circle. below the 6th floor, when the reatail podium finishes and the tower facade begins. it would be about one and a half stories high. about 24 feet or more than 7 meters thick.

not sure how fast 432parkave will rise but it should rise quicker then Mumbias World One due to simple floor plate, gonna be close
The date of completion is wrong on the diagram. This tower is scheduled to be completed in 2014. Nice diagram by the way. I liked it.

The 225 West 57th Street is going to blow them all away.

I wonder if they're preparing to install the windows.

As I''ve previously commented, I think that this tower will be a nice eastern bookend on the southern Central Park skyline contrasting with _225 W 57th at the west end and with Torre Verre and One 57 between them.

Looks like its going to be a whole wall that will transfer the load rather than a transfer beam. The opening you see in the section drawings would indicate an opening for a door way/walkway linking the two retails area together. Further you go up, the less strength concrete you need, therefore weight of each floor is reduced by a certain factor each time you go up. Plus this building is not even the large in terms of gfa per floor, so this transfer point will easily handle everything above. Highest strength concrete will be found at this transfer point.

They might, but I think this is just a fence stopping workers from falling down.

Working deck and trailing decks. Trailing deck(below) allows the workers to strip off and cure the concrete properly whilst new forms can be installed and poured on the working deck(above). Same principle as core construction.

just been watching that, looks like it take them a while to thread it through to get it in the right place.

As 432 Park Avenue continues to grow, and the new floor level is being formed up, several things are going on now. A large rebar cage is being placed at the north side, for a concrete beam. An interesting observation to be seen from the 57St cam, is what appears to be a new barricade on 56 Street. I am wondering if this new barricade will be for a new concrete pump, as the truck-mounted concrete pump that has been used to pump concrete up to the core-mounted placing boom can no longer reach the top of the core. In addition, if you look closely at the Park Avenue cam, there appears to be a protective canopy being assembled for pedestrians.

This floor is going to be post-tensioned. You can see the steel fixers laying out conduits and running cables on 57th St cam. This must be the floor before 4 columns become 7 columns. Btw black forms for the floor slab makes no different from wood coloured forms. Same thing.

Preparations begin for jumping the 57 St crane. Currently the trolley beam is being installed onto the slewing ring, in preparing for the arrival of the tower sections.

No doubt, the same will happen soon to the 56 St. crane as well as the building rises..

Currently, the 57 St crane is lifting a new tower section from the large opening on the southwest corner. It most likely will be placed on its trolley beam for jumping. The tower section is now suspened in air, as the crane workers prepare to transfer the tower section to the trolley beam.

With the first tower section now on the trolley beam, a second tower section hangs supended. The crane must be in a state of equilibrium, hence the suspended tower section, while the workers unbolt the slewing ring from the tower section it currently bears upon. The slewing ring is bolted also to the clinbing frame. The climbing frame will rise, by hydraulic cylinderson each side, and the tower section that is currently on the trolley beam will be slid into the climbing frame.

The first new tower section has been slid into position within the climbing frame, and placed atop the previous section that the crane had rested upon. Workers now bolt the new section to the previous section. Meanwhile, work continues with forming the new floor level on the 56 St side.

Up she goes. The crane goes up another step to accept tower section number two.

Actually they have a third piece on the cable - so I guess they are jumping three levels today.

Might just be me but the crane on the 56th street side looks taller in the webcams too.
