If electrical and plumbing needs rework can the walls be safely cut without to much structural damage? How would repairing the cuts work?

If one needed to re-run electrical wires, I assume you could drill holes and pull new cabling through the walls into the attic space.

If you had to re-run water or sewer, you have to jack hammer the foundation. But that is the same a wood frame homes.
