I'm curious about the (I assume Sch 80) conduits coming up in the midst of the foundation. I've never seen this before. Only inside or outside.
Was it done for security or some other reason?
What does the finished product look like? What happens if you need to replace your service equipment?

All are sch 80, yes. We do our custom homes like that and especially in the higher snow country around Lake Tahoe. Although there is no code that sez you have to, long as you use sch 80 above ground.

That little room under the stairs and deck is more for sheer load as the structure is 35 feet high and the engineer wanted it so I put it to use and gained some floor space. We have a wind rating here much like Florida with 120 mph wind load + snow load.

It is interesting. We run many conduits through slabs, but not foundations or wall footings. We use concrete encased PVC below the slab, transitioning to rigid galvanized steel for elbows and where it comes up through the slab. I assume structural issues have been checked?
