How does it work when hiring a structural engineer?

Hello!

The building permit unit requires construction drawings/dimensioning. How does it work when hiring the help of a structural engineer? Does the engineer need to be certified in the same way as the control manager? Who decides what in the construction needs dimensioning drawings?

What are you applying for building permission for?

Large extension with a 120 sqm building area. Last time I built, a structural engineer wasn't needed since I built a single-story. Now that I'm building two stories, the municipality wants dimensioning of the intermediate floor, among other things.
