hehe yeah and the BG-Bau will also come knocking at the door with so much "assistance" at the construction site...
Well, let him do it...he can report back...
from a mechanical engineer to mechatronics technician...looking for another forum makes no sense...in Germany there are regulations, laws and ordinances...which unfortunately have to be complied with in construction and also apply in other forums...
no reputable company will build a basement or floor slab on a plot without a soil survey. Because then you can hold that company liable for any damages in the future, etc. this has nothing to do with the users here we simply live in a state governed by the rule of law...
P.S.
my turnkey house ended up costing 25% more than the list price at the bottom right, among other things because of all the incidental construction costs and the landscaping were extra on top
