Cement pumper here, guys scurrying around finishing the forms.
Pouring above, adding bracing below. No cement vibrator in sight.
They all packed up and went home, but it looks like they forgot to finish one section.
You mentioned you didn't see a single vibrator For a pour that high they must have used super plasticizers and maintained a very low air entrainment factor with small to medium aggregate not more then 1" the plasticizers would allow for a high workability with a high slump without the need to have a very wet mixture.
You also mentioned they were still adding more bracing could they also have been slapping the forms to settle the concrete. I doubt if I will ever understand why here in the states contractors use that OSB panel instead of Phenolic film plywood for their forms. I guess it boils down to cost and availability here in the USA.
We tend to think of it as an exotic form of plywood while in many countries it is considered the norm to be used as forming materials. One thing is for sure the 18mm phenolic plywood will yield a glass smooth finish to the pour.
Never try to tell me it can't be done

Amen to that, Frank. Not only will the surface finish be smooth, but also when cutting these sheets,Originally Posted by Frank S
the edges and its splints are sharp like razor wire, and won't easily bend or break away,
and these mothers will cut right thru your glove and into your hand like a surgeon's scalpel if you're not attentive.
This morning they topped off the part of the form that wasn't finished last night. I can't believe they left it partly filled overnight, that's got to make a poor seam.
They've spend the day stripping and cutting up the rest of the forms to haul off. I'll see about getting a photo when they knock off for the day.
Topped off the part they forgot.
Some patching needed
You see, they were going to use vibrators but when they called Good Vibrations and asked for a 14 foot vibrator the sales person passed out.

That's a poor quality pour the jack hammers should already be hammering away. But they will probably just spray it with shotcrete or gunite like you would do a pool and tell the homeowner that is how it should be done.

A lot of the forms are still up but I see they're carving on the bit they did uncover.
something sure doesn't look as if it went exactly as planned but maybe they are having to carve due to a change after the forms had been put in place or maybe what ever needs placed there it is easier to carve out the relief. But for what ever reason there still seems to be a lot of voids tat are going to require filling which should not have happened. If you see voids like these in as many places as we can from our limited view angle there are probably even larger more numerous voids we cannot see. This pour needs sounded 100%.
If not then let's hope it is only a 1 or 2 story But I'm not up on residential all that much all I know is any civil engineer I ever worked with would have that entire pour brought down he wouldn't even consider allowing an inspector seeing it to write up a report. What would have been the big deal to rent a few vibrators for a day?
