^ looks like they’re setting up supports for the 2nd level decking.

Form work moving on up on the beams.

 

[jibsta]

that next pour is like 100,000 lbs of cement, crazy the form can hold it.

The angle irons supporting the forms only support the weight of the forms regardless of whether concrete is poured or not. Based on the height of the form you would be looking at a pressure of about 20 psi at the base reducing linearly to 0 at the top of the form.

If that's prep work to construct the first floor above grade, it seems a lot lower down than I was expecting it. Perhaps I missed something in the rendering fine print.

Presumably there’ll be another layer of scaffolding on top of that first one to bring it to its final height,

I don't think that's the level they're forming the first above-grade floor at. I imagine because of the ceiling height, one set of supports are not tall enough to hold the forms in place and as such a second 'level' of supports will be needed above these - and they'll be placed on top of the level it's at currently.

Yeah...that sounds just about right. Thanks for explaining that you two. /bows

Forming could easily go the full height here. I suspect we have something more interesting going on.

In my 40 years in the business i have never seen jacks that would extend that high to support the formwork.

I've been on sites with uninterrupted scaffolding & formwork slab support at these heights in industrial applications, however I don't believe jacks were used. Commonly done in bridge construction work too.
