Defects in the screed - empty conduit missing!

Now the underfloor heating and screed have been installed at our place. Unfortunately, a few things went wrong.

1) A conduit pipe intended for the stove connection in a kitchen island in the granny flat was simply 'buried' or pulled out beforehand. Now we cannot put a stove on the kitchen island (you can’t just let the cable hang from the ceiling). So I basically see only two options: break up the screed and lay a new conduit, or not have a kitchen island. But shouldn’t the cables actually be under the underfloor heating? So does that mean the heating also has to be removed and reinstalled? Two other conduits are also not where they should be. But with those, it’s just annoying and not that serious.

2) At one point the edge insulation strip was missing. Now the screed has run into the manifold of the underfloor heating (picture).

3) In many corners the edge insulation strip is also not ideally installed. There are gaps of several centimeters between screed and wall.

4) Inside the house, the insulation strip near the connections for the kitchen island there shifted, so that part of the pipes are now in the screed (picture).

5) For the actually square (30x30 cm) laundry chute shaft, the opening was made about 25x35 cm now. They simply stuck a box that was lying around there into it, which was not square. So the planned insert no longer fits, unless you partially remove the screed and fill in on the other side (picture).

6) At the transition from the utility room to the corridor, the insulation strip also shifted, so that the screed is connected between the rooms. Doesn’t that create a sound bridge? Especially in the utility room where the washing machine is, it shouldn’t be like that (picture).

7) The installers let some pipes come out directly at the walls. Some of the pipes are now enclosed by the insulation strip, while in others it runs between pipe and wall. That seems rather random. How should it be done now?

8) The offer stated anhydrite screed, but cement screed was laid instead. The screed installer said there were delivery problems with the anhydrite screed, so they took cement. I am supposedly not disadvantaged by this. Actually, I don’t have a strong preference for either type, but just changing it without discussing it first seems strange to me.

All in all, I think quite a lot has gone wrong here. Or is it still within limits? Additionally, there were several cigarette butts lying on the screed throughout the house. That’s certainly not a defect, but I found it rather strange.

I would immediately report the kitchen island and the laundry chute as defects and ask the screed layer for clarification. You can also address the other points at the same time. Do you have an external expert or a site manager?

I wouldn't accept that. It was just botched... Were the things discussed beforehand?

That was a recommendation from acquaintances. Probably not a very good one. We have not yet involved an expert. I wanted to first see if these are even defects, because the screed layers are of course downplaying everything. But I still find the switch from anhydrite to cement strange. I googled it once, but didn’t find out if one is more expensive than the other.

Oh yes, I have one more: In the bathroom of the granny flat, the underfloor heating was supposed to stop about 20 cm before the tub, because a railing for getting out is supposed to be installed there at some point (it’s for my parents-in-law, who are not exactly young anymore). And what do we have now? The underfloor heating goes almost up to the tub, but the screed stops 20 cm before it.

What does your site manager say about that?

Raise the alarm immediately and get expert advice. This is madness...
