ᐅ How much additional cost is expected based on the structural engineer’s calculations?

I see both parties as problematic. On the homeowner side, there’s a toxic mix of ignorance and resistance to advice. On the builder’s side, there are questionable business practices where houses are sold to naive customers at rock-bottom prices, only for half the cost to be added later as change orders.
I’m building for the second time now, and neither of the two builders I worked with ever pulled or even attempted anything like that.

Well, it was our mistake for not researching the basement issue more thoroughly. The offer (cover page) did mention that depending on the soil type, there could be significant additional costs. So it was our responsibility to commission the soil survey independently before signing the contract, not only as part of the detailed planning phase.

This is just an offer

If I understand the last 20 pages correctly, you are defending a company that wants to sell you a basement without waterproofing and at the same time charge you €30,000 (about $32,000) for the waterproofing (black tank). Now it will at least be a white tank. By the way, this term is not a protected or strictly defined one. The quality and composition of the concrete are what matter here.

However, the construction company is not the problem here. You simply have no idea what you’re doing, so the general contractor can do whatever he wants with you — and he is doing exactly that.

and which two construction companies did you build with?

Regardless of your soil conditions, EVERY basement needs waterproofing. They tried to sell you a black tank membrane at an extra cost, even though the offer states "including basement". Without knowing the exact contract text, this sounds very unprofessional.
