all our walls are made of reinforced concrete. The electrician therefore has a lot of work creating the channels and holes for cables, sockets, switches, etc. Some of the holes have a diameter of 6cm (2.4 inches). Some empty conduits are also present, through which the old cables were routed. However, the electrician says they cannot be used because the diameter is too small. Since we want more power outlets overall and also LAN cables in some rooms, too many cables would have to go through the existing conduits, and for the new sockets he would need a diameter of 80mm (3.1 inches). Is this all normal? Or is it reasonable to ask that at least some of the conduits and holes still be used—for example, in places where no new socket is added, wouldn’t the cables still fit through the conduit? Or would that seem too picky? Overall (it’s a large house), it adds up quite a bit if everything has to be newly drilled, milled, or chiseled out...
Thank you very much for your tips!

hampshire31 Oct 2020 22:33Sounds like a planning error. If the space inside the designated conduits is insufficient, chiseling into the walls is necessary. Installing some cables in the chisels and others in the conduits may seem practical at first, but overall it makes everything more complicated and less clear than needed. I would recommend placing everything in the chisels as advised by the electrician.

I forgot to mention earlier that the house was built in 1966. So, the design was probably suitable for the needs at that time.

Are all the walls, including the interior ones, made of concrete?
Putting grooves in concrete is a huge amount of work and can also cause structural issues. You should definitely have someone knowledgeable take a look before the electrician starts.
I would probably try to do as much as possible through the floor since the grooves will be shorter there. For walls with a lot of installations, you could also consider a drywall partition.
