I have attached this video , very long , but the important part is the early part.
My takeaways
Incredibly code and inspection compliant , re for builder experts on here
The walls are single leaf concrete blocks.
Steel protruding from slab
In this case wall on rebated slab edge , from video more of a best practice thing.IMO , would make it easy for external walls by Hadrian , as bricks in internal wall would be at a different level.Would not be surprised if demo includes walls on rebated slab.
Talks about bonded beam blocks , concrete lintels and how windows are inserted , techniques .
I found it very interesting , reinforced all the work and direction FBR have done .
Hadrian glued blocks , just replace the concrete block and mortar part of the home and single leaf wall construction
