I am in the design portion of this business (that for background). I once did the design and followup inspections/observations for a project in Va. for the Univ. of Richmond. It was a major re-work of a mens dormatory. Almost all the conduits were chisled into stucco type walls, including receptacles, light switches, and to the light fixtures. The contractor did a great job of concealing the conduits. Boxes were generally 4X4 welded construction.
I think it would be very difficult in solid concrete. I would probably get it roughed-in, then let the concrete be poured.
Just my opinion.
