ᐅ Cost Comparison: Reinforced Concrete with Exterior Insulation and Finish System (EIFS) vs. Brick or Masonry with EIFS

Well, that’s what this seems to be about:

The original poster asks in the first post about the alternative "solid brick with plaster."
That would be a Poroton brick, and of course, that is a valid alternative. A single-family house where that doesn’t work would have to be quite exceptional, but the original poster hasn’t shared the floor plans. It’s also common to incorporate reinforced concrete columns locally into the masonry if necessary.

Sorry @nichts zu schwör
but you’re just writing confusing stuff again.

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

@Lumpi_LE

That would be a Poroton block, which is certainly a viable alternative.

Just because the original poster’s assumption is 99% wrong.
Why would a structural engineer specify reinforced concrete or calcium silicate bricks,
if standard masonry would be sufficient?

Maybe the load-bearing capacity and bending moment from the OP’s structural analysis will be posted,
then you'll know for sure.

The structural engineer said about our design that, due to the window openings, it would probably be best to build both floors using reinforced concrete.

1) So the structural engineer hasn’t completed the structural calculations yet.
2) He doesn’t mention anything about sand-lime brick.
3) “Probably best with reinforced concrete” does not mean he considers there is no alternative.
4) For a structural engineer, reinforced concrete is always the safest choice because it requires less consideration.
5) There is a possibility that the structural engineer lacks expertise.
6) But none of this is relevant to the original poster’s question, who wanted to know about costs—and as he himself states, reinforced concrete is the most expensive option.

1) It doesn’t matter, since the structural engineer won’t be an idiot. We don’t know what is meant by “design,” but often a design suitable for a building permit / planning permission is meant.
2) Just another incorrect claim from you.
3) There is always an alternative, which may not be obvious to you as a layperson. I even suspect that calcium silicate brick has already been mentioned as an alternative.
4) Just another false statement from you as a layperson.
5) Here, it seems rather that you don’t have any expertise...
6) Good that you have now understood the question as well.

To be honest, as a builder, I would interpret the structural engineer’s comment as a suggestion to check whether the window openings are oversized.

In my opinion, insulting the expertise of fellow contributors is somewhat more part of the community culture in the green forum than it is here.

@11ant You don’t really believe he is a structural engineer qualified enough to question another engineer’s competence, do you?
