I note they only place the concrete one small section at a time (to reduce cracking?), but that results in cold-joints/seams... what kind of sealant/rope-caulk/etc. is used to seal the seams?
Sure you want to put roofing finish on that. 50+ years ago we'd do asphalt strips and that was it. These days you do something like bitumen paint or asphalt strips, blue min. 150mm thick insulation boards, hydro insulation foam.
Don't know if you're still watching the comments, but a few questions. Did you do anything over the concrete for a finish, or is the exposed concrete the finished roof? What PSI rating was the concrete 3000 PSI? 5000? Something else?
Guessing they might not know what the PSI rating was. Nor did they care. They are not going to be driving semi-trucks on it. Slump might be a different matter as they needed the concrete to be easily worked on a sloping roof. Would guess that roof ended up being multiple time stronger than a wood roof.
@@ArnieD17 For sure the PSI matters. To get the permit in CA, the PSI would be specified by the engineer of record and the mix design would have to be certified by the pre-mix company to meet that spec. Given that human occupation occurs under that roof, it is also likely that an inspector was required to take sample cylinders during the poor and have them compression tested at specified intervals (especially before the falsework (form supports) are allowed to be removed.
Def looked like a 3 slump pretty stiff stuff and foundations in my area r poured around 3000-3500, I pour all my driveways 4000psi, when u order concrete they ask u what psi u want and how stiff ur gonna pour so they know how much water to add when they leave the plant, also they wanna know if u want air entrained concrete or not
Sure gets my goat when I see a bunch of clowns almost intentionally ''walking the steel down' instead of stepping between the grids. Seems most of them don't have anything to do and shouldn't even be on the roof! In your opening minute and a half almost every one on the roof is standing on steel even with clear space around them while doing nothing.

I would have liked to see the Bracing th on the underside of the roof and what carring the roof load..on the valley and small gable
Is that reall enoug rebar? All concrete pours I've witnessed there was twice as many intertwined rebar connections as this...

I would also be interested to know "Did you do anything over the concrete for a finish, or is the exposed concrete the finished roof?"
Latex paint at minimum, but probably--since there are seams and micro-cracking and concrete porosity to worry about--a rubberized coating like R400.
Could rubber the roof and pvc glue and fiber coated

Good *fireproof* construction method for PRKali... ;')
No food for termites
@@nunayobusiness3384 yeah they like to tunnel through foam...but if the roof is concrete?

@@ArnieD17 I would think PSI rating would be one of the specification of the concrete order.

Concrete PSI always matters when used for structural purposes.

How the heck did you film that?
drone
flying robot 😂😂
really tall guy
Go-go gadget arms
He called Superman to be the cameraman
I’ll bet those guys were happy to get that job...LOL.
But seriously, nice work!
How.much does it cost ??
Typically ICF increases the cost of a building by 5%-10%
why? huricane proof?
Why? 🤷♂️
Boy oh boy. I can't wait to hire 10 guys to stand on my roof and waste my resources!? Sign me up.
Bombproof?😄

8 guys for a 3 man job lol
Get into concerte work you’ll soon find out why.
One guy wearing a hardhat. No fall protection. "Real professional crew"
Wow, and in regulation-heavy California of all places!... sad.
Looks like a government job
