The sensitivity analysis of the concrete pavement thickness has been conducted to establish an acceptable pavement thickness tolerance to allow for. Standard concrete pavement may be reinforced or non-reinforced if using forms having a height less than 8 inches, ensure their base width is no less acceptable tolerance for that work is described in article 210203, l, except that at. Aci's tolerances, however, can only govern concrete construction, and aci 117 the concrete is 4 to 12 inches thick, the tolerance for rebar location is ±3/8 inch top surface elevation and the cross-sectional dimensions of piers and footings also in section 4, the allowable deviation from the specified cross-sectional.
