The cable routing is not straight. In ceilings, the cables partially run diagonally across the room, the cables are tangled, in the utility room they first run in front of the pipes, then behind them, then in front again, so in a zigzag pattern, the cables do not have the correct length (the recess in the styrofoam therefore had to be cut wavy), cables were forgotten and were supposed to be laid loose in the screed (at least I put the foil for the underfloor heating over it). The switches are 12 cm instead of 15 cm from the doors. Empty conduits were not embedded deep enough, cables were forgotten, electrical plans were not understood, but he didn’t ask anyone (those were the forgotten cables), empty conduits were pulled where they were not wanted, too many holes were chiseled.
