Looks like the floor rebar is done on the lower level. So maybe they could do a pour tomorrow? I would think they'd like to do it on Fridays so it has a few days to cure.

Whenever you post stuff like this, I feel like you know something! I read on WNY that the buildings concrete will have chamfered edges, and the developer wants the concrete as smooth as possible and white. Anything you can add?

If anybody knows anything about new buildings, it's Bob. I learned to trust him on this stuff more than any other source on the net

No. Irish on WNY has better info than I do because apparently, he's directly involved engineering/construction end. I only get indirect info on the legal end and therefore, defer to him.

Yeah, far from being ready.

It's only 1 layer of steel. Expect about 5-6-7 layers. Floor will be dark gray before the pour.

How can they have so many layers of steel? How think are these floors generally?

That's what I call a neat construction site, damn! lol Look at that! Anyway, I'm still not sure about this. I bet once it's built it will convince me, but for now..mmm =/

First step, depends on what type of building is. It's different for houses, skyscrapers, etc.

Second step, depends on how how big is the surface (floor slab) from wall-to-wall.

Third step, depends on how thick is floor slab, which depends on second step.

Fourth step, depends on what is gonna be in that room (offices-people or mechanical room-heavy machines).



Engineers get info on what is planned for which part of the building, get architects blueprints and then they calculate how thick floor slab should be, how thick rebar should be, how many layers of steel should be in every slab, is it the web or single rebar, in which direction should be layered how close rebar should be in the web of rebars, etc.

I remember when we were doing those calculations for houses in the high school. Pretty cool stuff. Specially if you get project like this, thin and tall. I'm sure engineers spent impressive amount of time and knowledge in this project.

By the way, there are no further plans to increase the height.

I'll take that bet. $100, easy.

And I can show on this board where completed projects have changed my opinion so that you know I'm not snowing you.

Another thing I've learned from this cam: I thought constrution was often shut down by inclement weather. Now I know it isn't. It is a horrible yucky day in New York and they are plowing ahead on the site.

Love it.

The floor slab would typically have four layers of reinforcing steel. The size of the bars used depend on the floor loading (live and dead loads in pounds per square foot) and the span between supporting columns. Typically noted as an example: "#6 E.W. top and bottom, meaning #6 (size of bars in 1/8" increments) E.W. (each way) top and bottom (near top and bottom of slab).

Rain slows this type of construction, but work can still proceed. As floors go up, rain may slow work on the topmost weather-exposed floor, but other trades can continue work under cover on lower floors. In earthwork-type construction (for example, highway construction), rain can stop work (muddy conditions, machines getting stuck, slowed production).

When we did the mock up for the building, it was indeed white concrete and chamfered slab edge. It would have been to hard to make the building white. The consistency of concrete color and have concrete trucks and a concrete plant dedicated just for this project.
Does anyone know who the surveyors for concrete sub contractor are? This will be one difficult of a project for them!!

I really need to learn this professional terminology in English language.

That's right. Although I'm more familiar with metric system, grams and kilograms per square metres (newtons and kilonewtons).

E.W. means grid made of bars, connecting the reinforced steel of floor slab with all four walls or concrete beams on columns.

Bars are located on the bottom and near the top because of tensile forces.

Which means that 426 meters/1398 feet is the final height?
