In connection with training, I have been given an assignment where we, among other things, will convert a storage room with a slab on grade to a living space.
I am a bit unsure about what is commonly embedded in concrete slabs. In this case, a portion of the slab will need to be broken or sawn to lay sewer pipes. But what about water pipes? Are these embedded somewhere or are they allowed to come up from the ground and into the wall? Considering the risk of frost and such, I am thinking about where you connect water pipes from the water supply network.
I assume that electrical wires are not typically embedded, but instead enter through the wall. Right?
We have a water pipe that enters the basement about 1-1.5 meters below the ground surface, so we have nothing else to compare with.

My amateur answer is that incoming water comes up from the slab, but not electricity, as it is connected to a meter cabinet located on the facade. I don't know how they do with fiber in new constructions. Then it's very common to cast in floor heating pipes throughout the slab.
Edit: But cast-in floor heating requires the slab to be insulated underneath, so probably not applicable when converting a storage room.

Are we talking about electric or waterborne underfloor heating? A bit off topic but considering the current energy situation. However, I know an acquaintance who only uses underfloor heating for heating, but as you said, it requires insulation underneath.Magnus E K said:
Drains should of course be embedded, as well as water, "pipe in pipe" is the standard. You run electricity by laying a yellow 50mm conduit through which you pull the wires, and you also lay another conduit for fiber. As for insulation, a storage slab may be poorly insulated, so you can advantageously propose floating EPS insulation. If you plan to have hydronic underfloor heating, it's available with grooves for pipes and heat distribution plates, and the supply and return pipes for the underfloor heating should be led through the concrete slab as well (insulated pipes for both supply and return). However, an air/air heat pump seems best, and then you can use standard smooth EPS S200 or S250.
One can cast in a solid part. But it's only the drainage and possibly the incoming water that must be there. However, if one plans for routing from the start, it is easy to lay other things there as well.
I can imagine that it gets quite complicated if you have to dig up a whole lot of trenches in the slab. Thinking about future load-bearing capacity and such if you're in and demolish too much.
But water and sewage at least should be dimensioned for?
But tearing away the whole slab and recasting is probably even more expensive.
Forgot to write that there is insulation under the slab, some form of foam plastic, it's not clear from the information, but the drawing shows insulation underneath.
