Tolerances, according to the commentary to ACI 117 are a means to establish permissible variation in dimension and location, giving both the designer and the contractor limits within which the work is to be performed. Tolerances provide a way for the structure's designer to let the contractor know what is expectedto define the acceptable level of imperfectionsince it is understood that No structure is exactly level, plumb, straight, and true. ACI's tolerances, however, can only govern concrete construction, and ACI 117 notes that Materials that interface with or connect to concrete elements may have tolerance requirements that are not compatible with those contained in this document.. the value of yield strength, having a prescribed probability of not being attained in a hypothetical unlimited test series. )@4 >_EW,Cm8)%PYG#Ik";AHEUL=@@:1ZtZW7V0PZ`2]a48Xu-@j1riqU"NYK5F.U=(A?&BbXE/>VBUtc0Q'\/S]3+TTu4"F 0XPb>_IV.6m1ZBed-mVaVMuSeX5lI"iI*gjJCL+'kMZp^H-SnBq\;6j/q:%A/'@&) `+!5tHd'&'/!s/k>b`@ach(SLKlYG',LSnch(:q?$7Y%F?'5r@0mtLq%]qK$@%]IAM\SkKOF?
