What costs should you roughly expect per cubic meter if the soil report comes back unfavorable?
Our soil has a high clay content, and we are concerned that we might need to carry out soil replacement.

Of course, you only know for sure after the soil report, but we want to have it done as soon as possible so it can be included in the financing if needed.
Such a report doesn’t expire, right? Especially since soil conditions usually don’t change.

Thank you.

That’s quite a summary, thank you!
I’ll now look for a local provider who can prepare a soil survey according to DIN 4020.

Thanks!

One more question right away:
Where should the drill holes be made if the building permit / planning permission window is not yet finalized?

I can only agree! Our soil report included a foundation recommendation. The slab contractor could do little with it, but your earthworks contractor certainly can.

Our report specified exactly that "Schroppen" of a certain size should be incorporated and how deep this should be done.

Since our soil turned out to be less problematic than expected, our earthworks contractor, in consultation with the soil expert, modified the foundation slightly.

I have a very good feeling about it.

Since this is a prefab house and we are ordering the foundation slab through the supplier, we will probably have the groundworks done by the same company, so we would have everything from a single source.

Of course, this depends on whether the price is reasonable. Otherwise, we will look for another groundworks contractor.

And one last question, just to make sure it’s not overlooked... Where should the drillings be made if the building permit / planning permission window is not yet fully finalized?

Regarding your question: I’m not sure... we had the survey done shortly before.

For your information: the earthworker is responsible for excavation and backfilling, while the foundation slab is constructed by a masonry/concrete company.

Have you already ordered a house, or are you still in the land purchase phase?

Thank you! It's clear who is responsible for what.
Our prefabricated house company works with a firm that handles the earthworks and the foundation slab, so both parties can usually rely on each other, and it is ensured that everything fits together properly.

The plot of land was inherited, and a contract securing the terms was signed.
