Hi,
thanks for your answers. Ah, thanks for the note, I was able to identify potential options through small asterisks. I wonder if the creators realize that as a layperson you don’t immediately notice this and the offer might possibly "drop out" even though they would actually be cheap because you simply don’t need certain tasks. So—now it already looks better, we are now between 900-1200 euros. I assume that a contaminant analysis will not be necessary, but if something turns up, of course, it has to be done—but I have the soil report for the road extension. One survey is about 25-30 m from our house and the other about 120 m, and both samples are almost identical within a few centimeters, so I’m just being optimistic and hoping it will look similar for us. An inspection will of course be made, but I am not expecting any surprises now (which one can experience even with a report during construction—and suddenly there was a rock). Thanks for the info—it has already helped a bit.
