Does anyone know of an online source for above and below grade cast-in-place concrete walls? I am bidding on an addition to a commercial building. It is drawn for an 8" wall with two horizontal #6 rebar every 18" oc and one #6 vertical every 9" on each face. These walls carry, wall and roof, TGIs spanning all of 16'. Just a little over-kill.

The rebar sounds heavy.

I discovered in the last month after 'Discussing' rebar size and spacing with a particular engineer he was not taking the 'perfect' cure environment into account in his walls which explains the excessive bar he had me trying to deal with as well as the wall thickness. What he designed was fine for regular cast in place but not necessary for ICF, which as we all know gives us a little advantage if designed properly

We encourage all of our installers to bid as drawn. As soon as you start messing with rebar schedules to get an advantage on price, you're playing with fire -- unless of course you're a PE and willing to bear the liability. Just sayin...

Sorry for the duplication -- not sure how that happened...

Good advice Bruce, I advise the same and I did bid as drawn, but since I know it is way overkill and the customer's engineer is "on something" I was looking to provide an alternate with money better spent.

HI ICF,

To my knowledge there are no rebar tables for commercial jobs. The closest you have is IRC which gives you the option of going either with IRC itself or PCA-100. PCA-100 is basically the most comprehensive prescription for residential ICF construction.

Advice - if the commercial job is large enough (large enough being a relative term you can go back to your ICF manufacturer to recommend you a "lean" engineer. I had one in TEXAS that used FEA on already engineered jobs, it paid for his work and saved the customer a bunch of $$. FEA (finite element analysis) is is basically drawing it up in 3D and analysing every cubic inch of the structure... bet there's different methods...
