Footing Tolerance

Footing Tolerance

Footing Tolerance

Hello All ,

So I took an exam recently that asked the questiion

Q   What is the tolerance of the concrete for a footing as far as the width .  It gave I believe 1/2 " , 3/8", 1% and a couple of others.
Not asking for the answer, as I would like to review this. The test referenced ACI 318 and 301 . I don't recall ever seeing this in either one of those books. Can someone point me in the direction of the section that may be in ?
Thanks  for the help  

RE: Footing Tolerance

ACI 117 covers tolerances (look at section 3.5).  Most other references (in 301 & 318) have been moved to 117.

RE: Footing Tolerance

Could the question have been asking you to calculate how much eccentricity the footing could withstand for a given load without overstressing the soil matrix?
