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

Created on: 11 Jun 2023 11:17

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

No, it’s the black tank.

For now.

Soon it will be the additional reinforcing steel, changed construction schedule, bad weather, excess excavation material, soil replacement (since no load-bearing soil was found during excavation), material price increases, wage cost surge due to an extreme collective bargaining agreement, and so on.

I understood the original poster to mean that they initially had a budget that covered the waterproofing (black tank), but now the builder has said that after the structural engineering calculations, an additional vague surcharge is expected.

It’s already mentioned in the headline.

So, I honestly don’t understand the concept of the company HDH.

I do. It’s called change order management.

That’s lesson one in any site manager training.

You might be right about that.

For how many square meters? A proper storage basement or for living use?

The basement is 70 square meters (750 square feet). It is not intended for living, only as a hobby room. The basement will not be finished for the price quoted but will remain in its raw state. Only the anteroom will be completed.

I understood the original poster to mean that they initially had a budget buffer allocated for the waterproof concrete shell (black tank), but now the construction manager is saying that, based on the static calculation, there will be an additional unexpected charge.

That's correct. However, we haven't really included much of a buffer in the budget...

How is the waterproofing specified in the contract, and is it made of concrete? Is a plan part of the contract?

I would need to check the documents.
