Column in the basement ceiling

Hello!

I am currently in the shell construction phase of my house and the basement ceiling was installed a few days ago.

There was already a problem with the basement walls, namely that they were spaced too far apart. The reason I was given for this was (in essence) the following: The surveyor included the Styrodur insulation in the external dimensions of the basement. However, the shell builder did not take this Styrodur insulation into account – consequently, the connecting irons (on which the hollow elements of the basement walls are "placed") were positioned too far outward. When the walls arrived and were "assembled," gaps of a total of 10-20 cm appeared on each side. These were shuttered and then "filled" with concrete. A new insulation was then calculated, as it now has to be "thinner."

I already had an uneasy feeling about this, but my construction manager assured me that this is absolutely fine, and I have received a letter from the shell construction company stating that the basement was built according to a DIN standard (number not currently in mind) and is therefore "safe."

The basement ceiling arrived the day before yesterday. Although it was asked twice whether the dimensions of the ceiling were corrected due to the incorrectly calculated walls and this was confirmed, the ceiling elements also arrived with gaps of 10-20 cm each.

Is this to be classified as a defect?
Am I being too picky here?

Here are a few pictures:

My layperson's opinion: Total botch job - I wouldn't accept it like that! I would be afraid that the structural stability wouldn't be correct - with these gap dimensions.

Have the calculation of the plates provided. If there are any discrepancies, file a complaint. Consult a structural engineer.
