Statics

Hello,
in our house, 3 walls were demolished over 6 months ago.
An exterior wall, which was supported with 2 steel beams over the adjacent masonry (masonry consists of bricks).
A load-bearing wall inside, which is supported by 2 wooden posts measuring 16*16 and a 4-meter-long 16*32 beam under the ceiling.
A non-load-bearing wall, which we also supported in the same way with wooden beams as the load-bearing one.
Before the renovation, a structural engineer was here and said everything was fine.
Now we have hairline cracks on the walls in some rooms, but only in the plaster.
The floor has also settled slightly, about 8mm-1cm, which I can see on the door frames that are no longer exactly flush with the floor.
All only in the areas above the load-bearing wall.
Is it normal that the house might need to settle at first?
From the lower renovated floor, nothing can be seen.
None of the beams are bending or showing any cracks.

What does the structural engineer say about that? And what does the construction company say?

I wouldn’t find it very funny if the floor/the ceiling moves.

The construction company says it would be completely normal as everything needs to settle. I am a student and live with my parents. They are satisfied with that, but it still worries me. Maybe someone has had similar experiences with such a renovation?

Have an independent expert come in at a cost and check whether that is true. Everything else is negligent.

To get straight to the point: I have no idea about extensive renovation measures in an old building. However, the screed in a new building settles by about 1 cm, so one can deduce that a new screed in an old building, provided it is not a dry screed, also lowers by a few millimeters. Besides, one probably always has to assume settlement cracks where a lot of "mass" is processed? Regards Yvonne
