one more window question

Hello

The warranty work on our apartment is due. For this, we have reported all defects that we noticed to the architect. Among other things, these are draft points / leaks of about 10 cm between the window frame and the masonry (I hope you understand what I mean). Furthermore, there is a draft at the points where the crank for the blinds was drilled through the frame, i.e., through the metal cover. The architect(s) have now confirmed the appointment for correcting the defects, but they reject the two mentioned issues. The reasons given are: - No claim to tightness, as it is not Minergie standard (according to SIA xy) - The cranks were properly installed.

Can someone tell me how I can still get sealed windows? Or rather, which leaks must be accepted?

Thank you very much Andreas

The Swiss construction industry aligns its execution with EU standards, accordingly, the applicable standards in Switzerland would be "SIA 331 Windows and Window Doors" (this also regulates connections and thermal insulation!) and "SIA 118/331 General Conditions for Windows and Window Doors - Contractual Conditions for Standard SIA 331:2008" (this also concerns construction execution and defects).

Your architect cannot simply allow windows to be roughly thrown into the wall and then excuse it by saying "It's just not Minergie." Refer to SIA 331 and 118/331 and demand that he refers to the standards; preferably, he should bring the text of the standards to a meeting and explain the execution accordingly.
You do not have to accept leaks.

This is a clear case and we had it too. It is outrageous that the architect claims the windows do not need to be sealed. I have set a deadline for the architect to remedy the defects or I will go to a lawyer. In any case, he was reasonable and fixed it. This botched work must not be tolerated.

That is clearly shoddy workmanship. Such gaps of 10 cm, that just can't be true. They even have the audacity to claim these are not defects. Kind of like, audacity wins.

In this case, I can only shake my head. That the client has to accept such shoddy workmanship is unbelievable. This is a case for the court.

Or which leaks must be accepted?

There is no leniency in this matter, because I want tight windows, period. Standards still exist and must be adhered to. If that didn't work, then it must be corrected.
