Code Accepted Chairs for Foundations on Grade
Code Accepted Chairs for Foundations on Grade
(OP)
Hi, Please help! I know contractors are not supposed to use rebar resting on the ground to support rebar - for all the obvious reasons... but, I've tried to find what code or where this is specifically stated and I can't find it. Some posts on these forums say it's CRSI, another post specifically said CRSI does not specify chairs. Unfortunately, I do not have the CRSI Manual... so, I'm at a loss.
If anyone knows where it is and what it says and you could post it, that would be awesome.
Thanks.

Chapter 3 of the CRSI Manual of Standard Practice is devoted to bar supports. I can't do justice to 17 pages of information here. Bent rebar standees are commonly used to support reinforcement in deep mats and footing. They should be avoided against formwork, earth-formed sides, or other exposed surfaces. As with any bar support, select the material based on corrosion-resistance, appearance, durability, and tolerance requirements.
