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

Hello,

I have to admit that we approached the house construction quite naively...

We have already signed the detailed construction plans, and now the construction company wants us to waive our right to special termination in writing – is that even legal?

Now to the main question: we signed a fixed price contract (turnkey), but the site manager said that the price might change again after the structural engineer's calculations???? I mean, we won’t make any more changes to the plans, and we have already budgeted with the bank based on the known price – is this normal? It feels like buying a pig in a poke!

Best regards

Of course, there are other good construction companies, but I wouldn’t have paid less than with h&h either. And with contaminated soil, I would have had problems with any other builder as well.
And the soil contamination testing costs 1000 euros.

With another construction company, you might have paid significantly less by the end of the project, once everything is truly finished.
Here, you are comparing apples and oranges.

It’s like comparing a car bought from a reputable dealership with one where someone tells you: "This car costs €10,000 less than the one from the other dealership—fully complete! (* Headlights cost extra. Windshield wipers cost extra. Tires cost extra. Power windows cost extra. Gearbox oil costs extra. Fuel tank costs extra... we have a wide selection of alloy wheels (which cost extra))."

That can’t be the entire contract... my construction contract is 52 pages long...

This is just an offer.

Just as a note – with Hein von Haiden, the city villa with a basement would have cost me 530,000 euros, over 100,000 euros more, and I wouldn’t have been allowed to move the walls at all, only exactly as shown in the catalog.

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 euros for the waterproofing (black tank). Now it will at least be a white tank. By the way, that is not a protected or strictly defined term. The quality and mixture of the concrete are what count here.

However, the construction company is not the problem here. You simply don’t know what you’re doing, so the general contractor is doing whatever he wants with you – and he is.

This is an advertising brochure.
An offer includes a precise description of what will be done and, above all, what it will cost.

I see both parties as problematic. On the client side, there is an explosive combination of ignorance and resistance to advice. On the construction company’s side, there are dubious business practices where houses are sold at bargain-basement prices to naive customers, only for half the cost to be added later through change orders.
This is my second time building, and neither of the two construction companies I worked with have ever pulled or even attempted anything like this.

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

However, the construction company is not the problem. You simply have no clue right now, so the general contractor does whatever he wants with you—and he is doing just that.

Well, it was our fault for not informing ourselves better regarding the basement. It was stated in the offer (cover sheet) that depending on the soil type, significant additional costs could arise. So it would have been our responsibility to have the soil survey done independently before signing the contract, not only during the construction planning phase.
