What was included in the offer? Are you from Bavaria, can you recommend it to us?
To me, as a layperson, it looked quite extensive. Geological preliminary investigation and engineering geological report.
Soil structure, groundwater depth, load-bearing capacity, and always recommendations included.
This is one of the offices that our general contractor always recommends. So they are satisfied with it. It wasn’t expensive, so I am satisfied too.
I am from Bavaria, they are not. They are from Central Germany, but the travel costs are flat rate anyway.
