ᐅ Additional Costs Due to Revised Structural Engineering Calculations

Hello everyone,
We are currently in the final stages of our detailed planning. We wanted to convert a bathroom with a shower into a pantry and a guest WC. This would involve moving a wall on the ground floor by 45cm (18 inches) and adding an additional wall on the ground floor to divide the former shower bathroom. So far, we have not signed off on the detailed planning, but now we are being asked to pay €1500 net for a new structural calculation. Is this common practice?
I had assumed that the structural engineering would only be calculated after completing the detailed planning.
What do you think? Do I really have to cover the cost of a new calculation?

Just a basic question: Are you actually moving a load-bearing wall? I assume so if new calculations are required – but I can only confirm that on Monday.
I find it a bit strange that a fee is charged for something so small. I had a load-bearing wall opened up, creating a passage with a lintel, but no door. Other changes were not load-bearing walls. No additional structural calculations were requested. Maybe it really is about the sequence—that something was already happening in the background.

Okay, so this means we have to pay for a completely new calculation just because of one wall.More like it means the file has to be reopened and reconsidered at all.Andre77 schrieb:
I find it a bit strange that they charge money for something so minor.Often a flat fee with general contractors. As soon as a standardized house is modified, one charges 1500€ (or approx. $1500), another 3000€ (or approx. $3000). Why an individual design causes costs again, although the structural engineer is already involved during the planning phase, the original poster would have to explain to us. We don’t know to what extent the planning has already been completed. The contract probably contains some information that could clarify this.Tolentino schrieb:
There are probably regional differences.See above, more likely based on general contractor’s contract terms.W

More to the point of actually revisiting the files and putting thought into them.
Often a fixed service with general contractors. As soon as a standard house model is altered, one charges 1500€ (about $1,650), another 3000€ (about $3,300).
Why an individual design incurs additional costs, especially when the structural engineer is already involved during the planning phase, the original poster should explain to us. Because we don’t know to what extent the planning has already been completed. The contract probably contains some clauses that could help clarify this.
See above, more about the general contractor’s contractual conditions. I can only assume that the structural calculations have already been done, assuming no further changes would be necessary.
However, there seems to be no clear procedure on when the structural analysis is reviewed. In the end, we just have to accept this as a learning experience. If this is not an unusual practice, then the general contractor cannot really be blamed.
