Re: Q: Tolerances for Cast-in-Place Concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The tolerances for rebar bending, rebar placement, formwork, etc. are found
in ACI 117, " Standard Specifications for Tolerances for Concrete
Construction and Material.

I could have sworn I remembered seeing dimensional tolerances for concrete
in ACI; however all I can find are tolerances for placement of rebar (and
even then it's limited to "d" and "clear cover" (RE: ACI 7.5).

I've got a foundation stemwall, nominally 12" that in reality tapers to the
top of the wall so that it is only about 10" at that point. But how can I
complain if there are no published acceptable tolerances?

What am I missing?
