I find it a bit odd that money is charged for something so small. I had a load-bearing wall opened, so a passage with a lintel, without a door. Other changes were not load-bearing walls. Nothing extra was requested in terms of structural calculation. Maybe it is actually the sequence, that something already happened in the background.
Okay, that means we pay a completely new calculation because of a wall.
More for the fact that the file is even taken up again and has to be thought through.

Often a flat rate service with GCs. As soon as a type house is changed, one charges 1500€, another 3000€. Why individual planning causes costs again, i.e. the structural engineer is already involved during the planning, the OP would have to tell us. Because we don't know to what extent the planning has already been completed. The contract certainly states one or the other thing that could be helpful for clarification.
There are probably regional differences.
See above, rather contractual conditions of the GC
Rather to ensure that the file is even picked up again and has to be reconsidered.
Often a lump sum service with GUs. As soon as a type house is changed, one charges 1500€, another 3000€.
Why individual planning causes additional costs, even though the structural engineer is already involved during the planning, the OP would have to tell us. Because we don't know to what extent the planning has already been completed. Surely the contract contains one or two things that could be helpful for clarification.
See above, rather contractual conditions from GU
I can only assume that the structural analysis has already been calculated and it was assumed that no further changes in this regard would occur.
However, there seems to be no clear regulation regarding the procedure for when the structural analysis is checked. In the end, we just have to write off the whole thing as a learning experience. If it is not an unusual procedure, then one cannot really blame the GU.
