Live cam shows 9 construction workers on site, while two cranes are moving dirt.

That's all I need to know.

Trucks line up along the realigned barricades on 56Street, and can no longer back into the site entrance as before, as the ramp disappears. They are currently being loaded in the street by the triple-boom Hitachi EX800, the last of the big Hitachis that worked on the foundation. As predicted, the other Hitachi EX850 excavator that worked below has left the site. As foundation work has now reached the remains of the ramp, there is every possibility that truck-loading operations may continue this weekend, as slab construction has proceeded at a brisk pace.

Workers apply waterproofing to the future depressed slab area at the nook, with rebar being installed at the future slab section at 56St.

Marcatio, I've got a question about the crane footing.

You mentioned several pages ago about the template being placed. I remember it being a wooden form placed about 30 degrees clockwise compared to the slab. You can now see the "shadow" of that template.

Can you explain what that template is/was, why it is not square with the slab, and does it connect to the tendons placed around the perimeter of that 56th St. slab?

Thanks alot... This stuff fascinates me.

xnyr,

The template is a metal guide that was placed atop the steel legs that are embedded within the concrete. It is used to line up the legs that the crane tower base will be bolted. to. Reccaping the process, the footing was excavated, the footing pad was poured, the pad was drilled for the rock tendons, the tendons were installed and grouted, the reinforcement was placed, the four crane legs were then placed, plumbed and aligned with the template, then concrete poured to complete the crane footing. You can see the template just above the poured footing.

The tower for the crane does not necessarily have to aligned with the building. Perhaps the reason it is skewed is for structural reasons. The crane tower must resist the reactions from the crane as it works.

Here is a building that had a tower crane with its tower skewed in reference to the building being constructed.

This stuff also fascinates me as well!!

Thanks for the clear explanation - I must have missed the embedding of the crane legs - they're going so fast!

One more question - what do you think the 4 grilages in the core will be supporting? I know in Chicago, those were used to support foundations in the soft soil/mud.

Visited the site today to watch the truck loading operation. The big triple-boom Hitachi spending its last days at the site digging and loading out the ramp remains. Spoke to the crew there, the excavator will wind up out in the street, digging out the remains, loading trucks behind it. Digging should finish perhaps by Tuesday. Took some photos, and a video of the truck loading.

Rebar fully installed in the slab section around the crane footing and the pad for the Alimak material hoist that will be mounted alongside the tower, along with the east area by the nook. Concrete will commence on Monday.

With the big Hitachi digging out the ramp remains, slab construction will continue towards Park Avenue.

On the west perimeter wall, workers on the man lift ground the wall to expose rebar which is bent out to be embedded in future intersecting walls.

Does anyone know how tall the building will be at Xmas 2012 and also in a year from now. THANKS!

NewYorkDominates · #**2147** Posted **Aug 25, 2012, 3:05 AM**

Based on how fast the progress is,I think it's safe to say that by Christmas we should see a tower above ground level.A year from now:700-800'?

I've done a little reading on what is currently the tallest residential tower in the world.... and what is proposed to be the tallest residential tower in the world (under construction).

What I'm seeing.... is that quite a few of the ones under construction (in the UAE and India) are on Hold.

So.... with that said.... is there POTENTIAL that this might be the tallest residential tower in the world if completed on schedule???

Well, the Pentominium (516m), Dubai, is on hold. But World One (442m), Mumbai, is under construction.

So by 2014 / 15 the list will most probably read like this:

1. World One, 442m (roof 442m, top floor 420m)
2. Diamond Tower, 432m, Jeddah (roof ~ 360m)
2. 432 PA, 426m (roof 426m, top floor 397m)
3. Damac Heights, 420m (roof 420m, top floor ~390m)
4. Princess Tower, 414m (roof 392m, top floor 358m)
5. Marina 101, 412m (roof ~ 370m, top floor 354m)
6. 23 Marina, 393m (top floor 313m)

All those Dubai towers have a very large crown and / or spire. That's why the last occupied floor is so low.

I thought the Burj Khalifa was all residential and therefor the tallest residential building in the world.

^^

There's a hotel on the lower part of the BK, and 25 or so floors of offices towards the top.

Cool..... thanks Hunser.... so 432 Park Avenue would likely be the tallest residential building in the W. Hemisphere....... with the highest residential unit in the W. Hemisphere.....

and although "No. 2" doesn't capture the headlines quite like "No. 1"...... by highest occupied floor .... it would also likely be the 2nd tallest all residential building in the world upon completion??? Think that's a fair statement???

The Burj Khalifa is the tallest mixed building in the world.

Even if it won't be the tallest, it will be the tallest one in the best place. The New York views will also be incomparable.

I agree.

The only problem with living in this building, will be on cloudy days. You will only see clouds.

But with the weather cleared, the resident of the higher floors have amazing views of Central Park. Aahh, that lucky guy!

That list is a fail. Several projects are on hold or even canceled. 432 PA is not even included, together with some other 300m+ projects currently under construction.

Try CTBUH* , it's a way better source ... or even better yet: this forum.

Thanks, looking forward to the crane arrival.

Monday morning, 8-27-12:

As the big Hitachi at street level continues its digging, concrete is being poured into the section of slab on grade that was prepared last week. Concrete trucks back down, opposite to the normal one-way street flow, to the concrete pump, while truck loading by the Hitachi takes place. A steady string of dump trucks line up to receive their loads.
