Who has built with an architect? Experiences??

I guess that was a civil engineer? As far as I know, only architects or civil engineers are allowed to submit construction plans?

Term "Planzeichner".

With us, they are called planning office or construction planner. As WildThing has already said, they are often civil engineers.

Yes, that's why the whole thing seemed a bit strange to me. According to the builders, he could do everything, so I also assume that he submitted the construction plans. Hm.. but I don't know for sure.

That doesn't have to seem strange to you. The most optimal would actually be plans from the architect and construction execution with the civil engineer. That way you would have the respective specialty from both.

Now you say something... I just checked and our "architect" was actually also "only" a civil engineer. I had no idea...

You are good

Both are graduate engineers! Only those who are listed in the register of consulting engineers are allowed to call themselves civil engineers.
