^ While not exactly sure what this means or its specific importance, I think I really hope they are too!

Staggering of Rebar Splice Laps

Hello Texcolo

That is a good observation and point, but is it required in this situation, and should one do that?

From a load perspective, one normal to the ground and parallel, not orthogonal with the seam, would it not be better for a high rise to have that seam be as vertical and short as possible? Thus, generating less horizontal shear load component along the seam, producing a wall with greater torsional and tensile strength along the major load axis, in this example being vertical, not horizontal.

A similar analogy would be a non-wrapped seamed linear pipe. A pipe with a linear longitudinal seam being stronger than a pipe with a zigzag longitudinal seam.

Excellent work andy! I always look forward to these videos. It will be cool when this tower makes it to upper street level and we'll be able to get views from across the river.

When I was in college, worked with lots of rebar, and gunite. Later, as an electrical contractor in the life safety industry, worked on and visited many high-rise job sites, and massive public projects.

Hence, though carrying no weight, want to share that from what I can see, the team doing the rebar work looks SOLID. That if I were a project lead today with similar needs and requirements, would definitely give this team priority attention in the selection process.

Lap Splicing is used in splicing long sections of rebar together, these square core sections are made up of 4 long C bars, joined at the corners.

From an official looking PDF



What appears on the smaller photo to be a series (of non-lapped) splices is the ends of the long C sections that have the back along the inside of the core and the ends wrapping around the columns on each corner.


For the ties on the closing bar (making an O) an additional bar (of varying length) to augment the assembly.


The above articles mentions that extra rebar should be installed on the bottom of the walls to prevent catastrophic structural failure should a support column be lost.

Hello Texcolo and Harry C

Here are a few more comments regarding lap splices.

Post Tension

Cable are run through the concrete members and slabs before they are poured, later they are tightened down to compress the concrete (tension the wires). More at NYPT

It's breast cancer awareness month




smoothing the concrete.


I guess the re-bar will be installed and the floor poured before the forms are closed and the wall poured.


It's nice and dry between the form walls.


A really long post stress run.

I really agree with whomever said earlier they had a feeling this one is going to shoot up fast.......it really is going to fly........topping out could very realistically be less than 12 months from today I think...

I definitely agree with that statement, at the rate this already seems to be moving along, I can see this thing popping up over Upper Wacker Dr. very soon!

Just curious and a little off topic but does anyone know the next parcel they plan to develop in LSE?

Yeah I guess when you only have 425 ft for 49 floors it speeds things up. I think my neighbor would have to duck in these units he is literally just under 7ft tall

Yeah, I think between top of finished floor to bottom of finished ceiling it will be something like 7'-8"

Just measured the ceilings in my apartment and they are 9'-4" Don't think I could stand the low ceilings, but the view would make up for it.
