Three years ago, I enlisted the help of a structural engineer to calculate the load-bearing beams for my basement. It was an older gentleman who never visited the house but seemed knowledgeable and took the safe route in his calculations, so everything ended up being over-dimensioned.
One beam he calculated is the one measuring 3920mm in the attached files. Now I'm finally going to start fixing the basement and have begun to wonder if the wall is load-bearing at all. I've tried to get in touch with the structural engineer who helped me before, but he seems to have retired, so I'm turning to the forum for help. I might have missed providing him with some important information or similar, which led him to assume it was load-bearing when it actually might not be.
For example, there is a doorway in the middle of the wall today without any support towards the ceiling. It's just aesthetically bricked above the door.
The house was built in 1939. It has a solid concrete basement with floors, walls, and ceiling. On top of the concrete, there are wooden beams parallel to the wall I'm talking about. The house is a 3-story building with approximately 45 square meters of ground floor area.
Is it clear-cut that it's a load-bearing wall, or could it be worth investigating further? Or can we even dismiss the wall's load-bearing or non-load-bearing status in this forum?

It is the base drawing except that two non-load-bearing interior walls are also drawn (which I marked in red in the first drawing), these are newer/are yet to be built. Could it be a question of supporting the core wall/the house against horizontal forces? Maybe it isn't needed when the basement is cast like a bunker with walls and ceiling in concrete... it should become torsionally rigid, I think.TomasJor said:
It is a somewhat tricky drawing that unfortunately cannot be used as a basis for this type of question. An original drawing would have been much better. Much suggests that it is not load-bearing, but to say this with certainty, a reinforcement drawing is needed. The construction year, 1939, affects the assessment. It was very popular to give basements some form of shelter standard. Since you live in Stockholm, there should be a copy of the drawing at the City Planning Office.
