Cost comparison: reinforced concrete + ETICS vs. brick or wall + ETICS

Yes, that’s what this is about here:

The OP asks in the first post about the alternative "brick monolithic with plaster."
That would be a Poroton brick, and of course that works as an alternative. A single-family house where that doesn’t work must be very special, but the OP hasn’t posted the floor plans. It is also common to locally embed reinforced concrete columns into the masonry if necessary.

Sorry
but you’re writing nonsense again.

The OP isn’t reading anymore anyway, so there’s no point in replying.

Just because the OP's assumption is 99% wrong.
Why should a structural engineer then come up with reinforced concrete or calcium silicate brick,
if standard masonry would be sufficient?

Maybe the SFK and MG from the OP's structural calculation will be posted,
then you'll know.

The structural engineer said about our design that due to the window cutouts, it is probably best to execute both floors in reinforced concrete.

1) So the structural engineer has not done any structural analysis yet. 2) He says nothing about KS. 3) "Probably best in reinforced concrete," there is nothing here that in his opinion no alternative is possible. 4) For a structural engineer, reinforced concrete is always best, you don’t have to think much. 5) Is it possible that the structural engineer has no idea? 6) but all this has nothing to do with the question of the OP, who wanted costs and, as he himself writes, these are highest with reinforced concrete.

1) does not matter, because the structural engineer will not be an idiot. what is understood by "design" we do not know, but often a design suitable for building approval is meant. 2) just another false claim from you 3) there is always an alternative, which simply does not become apparent to you as a layperson. I even suspect that KS has already been named as an alternative. 4) just another false claim from you as a layperson 5) here it seems rather that you have no idea,... 6) nice that you have now understood the question as well

Frankly, as the client, I would interpret the structural engineer's statement as a suggestion to check whether the window openings are excessively sized.

2) only another false claim from you
3) there is always an alternative, which just isn’t apparent to you as a layman. I even suspect that aerated concrete was already mentioned as an alternative.
4) just another false claim from you as a layman
5) here it seems rather that you have no idea,...

In my opinion, competence-insulting among fellow responders is a bit more part of the culture of the community in the green forum than here

You don’t really believe that he is a civil engineer and so qualified that he can question another structural engineer’s competence, do you?
