Costs for soil replacement, soil survey for construction ground, clayey

I expressed myself incorrectly regarding lead time, according to the manufacturer it is not a requirement for execution, but it is recommended. So you can interpret it however you want. But as you already said, I will have the report done to be on the safe side, of course. Because the farmer doesn't care what happens in 5 years. But now I know what to do, thanks to you!

So, I have now found a company that even works with my house construction company. It was the cheapest offer of all requested, whether it is the best one, is unknown, but in terms of the service description it is identical to the others. The company for the soil survey even offers to request all necessary information from the architect and to forward the results to them as well, included in the price. I will probably wait a few more weeks until we have the initial meeting with our architect.
