This may be a violation since rebar degrades when exposed to soil. I had heard this but am not definite about it.I have the concrete guy stub a piece of rebar out from the footing. Then I go to the site and bend the rebar down so it will be below the poured floor level, attach my #4 and a listed clamp and tie it off to a form tie until I can get back to install the service.
No Dennis.....The rebar and clamp end up embedded in the concrete floor.
IRC [R403.1.3.1] Are there any inspectors here that are aware of this requirement?
R403.1.3.1 Foundations with stemwalls. Foundations with stem walls shall have installed a minimum of one #4 bar within 12 inches of the top of the wall and one #4 bar located 3 inches to 4 inches from the bottom of the footing.
Well here is the POV of an engineer who is guilty of this practice.
In the industry I work in we have engineering and installation practices to follow written by geeks like me. Makes life simple. The industry practices meet or exceed any code requirements. Basically we error on the side of caution, vs an EC POV of meeting the minimum (financial/code) requirement.
Now I do not say that to start any flaming, we just have different POV?s and interest at stake.
Thanks Chris, How would this be applicable in slab floor construction where the slab portion is used for the UFER and the floor thickness is the minimum 4"?
Floor slabs are not footings. There are monolithic slabs that do incorporate a footing within the slab.
Sorry for not being a little more specific. Occasionally a garage slab poured into a stemwall with ledge has a stub up in the floor. This is I believe a non-compliant use of a CEE due to less than the minimum encasement and the location of the stub up without protection.
This brings up conflict as a poor method for using the slab as an electrode encasement. Most installers do not include a protective raceway over the GEC in this method. Would you tag this particular lack of encasement thickness over grade configuration as unacceptable? rbj
The ACI 318 and 332 standards deal with the requirement for minimum concrete encasement for structural reinforcing bars.
I would fail a CEE that used #4 re-bar that did not meet the required concrete encasement of these standards as referenced in the building codes.
