Hi,
We've just had the drawings back from the Structural Engineer and he seems to have specified a ridiculous amount of rebar! Part of our build is a sub-structure/part basement, so I can kind of understand the need for rebar there, but there is also a huge amount in the rest of the building. We've recently been to a site to help with the building of an ICF house, and there was very little rebar in that build (just the corners and above the windows and doors). I suspect that my Structural Engineer has little experience of building ICF houses and instead thinks he is building a bridge or a carpark or something. We have approximately 4km of rebar for a 200m^2 house...and that even includes a garage with nothing on top of it! Horizontal rebar is ever 25cm, and vertical every 20/25cm as well.
Does anyone have any experience of Structural Engineers over-specifying? What options do we have? The Building Warrant was just approved today based on his specifications.
Thanks,
Alan.
