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

Some neighbors built partly without a basement and partly with a concrete basement.
At least you already knew that a concrete basement is necessary.

they said they can’t start the detailed planning otherwise.
That would have meant for you that you wouldn’t have to pay if you cancel. Why do you think you were advised not to accept that?

We don’t have it in writing yet, but as soon as I do, I will post it.
There is already something stated in the contract!!! I have requested this here several times.

I'll try again. If you are building a waterproof concrete basement ("white tank"), make sure to have an expert (who is managing your construction supervision) oversee the building inspection. Just imagine how many mistakes can happen. It already starts during the planning phase.

We do have a site manager, and so far we are very satisfied with them.
