Our case is similar. Own property, construction with a general contractor. The boss has a planner who makes construction drawings and an external structural engineer. The boss is authorized to submit documents to the building authority as an engineer. After the last conversation and handshake in his office, we received all the drawings as PDFs, we said yes, that’s how we discussed it, the general contractor then completed the building application, we went to his office and checked it again, including site plan, elevations, etc. The structural analysis was also included, although I don’t understand it, the Excels must be correct, we’re not building the Elbphilharmonie, and then we signed three copies. One for me, one for the city, and one for the district. With these, I then went to the city building authority, submitted them, they put their okay stamp on it in my presence, off to the district, three weeks later the permit plus fee notice arrived. And now we are bound by that. That’s how it is. Honestly, was it very different in your case?
