ᐅ Exterior walls built with a deviation of approximately 4 cm from vertical alignment

Hello forum community,
we are currently quite unsettled regarding our construction. Our shell builder has constructed an exterior wall with a slope of about 4cm (1.6 inches) from bottom to top. According to the site manager, this should not affect the structural integrity, but now the plasterer has to compensate for this error at the shell builder's expense. Since we are not experts, our question is whether this is actually acceptable and how the plasterer would correct this issue. Obviously, it means applying more plaster, but does the plasterer need to use any additional materials or tools to compensate?

About 4 cm ... I just can’t believe it.You can’t either, Büro_manager_, right? But you still want to act like you know better, even though you have no idea what impact 4 cm at this point can have...? How fortunate that the original poster can rely on your emotions!Almost as helpful as:

Your quote referred solely to the statement that demolition is unavoidable and, exaggerating somewhat, that the lawyer should already prepare the lawsuit.
@TE: once again, very clearly: I have no expertise, and please do not take my statements here in the forum as professional advice ... you should only rely on your construction supervisor for that, whom you are paying for this purpose.
It largely depends on the wall thickness... a 15cm (6 inch) wall with a 4cm (1.5 inch) deviation is seriously uneven and simply cannot withstand a downward force... with a 40cm (16 inch) wall, the situation is quite different (however, a 40cm wall is also significantly more difficult to build straight, I assume this is referring to a thinner wall)... Still, a lot of leveling has to be done with plaster. This means many additional tasks for all subsequent trades, and all because the mason did such a poor job...
P.S.
Structural engineering was a constant part of my entire studies...

This is definitely better than shoddy workmanship on site. So 4cm (1.6 inches) is already outside the limits specified in DIN 18202.
However, I still can’t imagine how something like this looks (except in houses from 70 to 80 years ago). Especially because the wall has to bulge in one direction. This means that corrective work to fix the defects is needed on both sides—the interior and the exterior wall.

Knallkörper13 Mar 2017 12:14The wall has to be removed without any ifs or buts, regardless of the structural situation. I’m not exactly sure how the rest of the wall assembly is designed or how the windows will be installed. However, I can already see several disadvantages and potential issues for the ongoing construction if it remains as it is. Just as an example:
- Will the exterior plaster be 4 cm (1.5 inches) thicker at the top than at the bottom? Has the plaster manufacturer approved this? Will it adhere properly to the polystyrene insulation, if present? Or will a sloped insulation layer need to be added to the building?
- Will the windows be installed flush with the masonry? If so, flush at the top or bottom? Or will there be a frame installation – possibly using profiles of different lengths?
This could easily lead to the next patchwork solution out of necessity.
