Every contractor who builds with concrete and does so under a specification would be wise to have a copy of ACI 117. Allowable elevation tolerances are +1/8 inch and -1/4 inch from the design elevation. Tolerances on the level of the top of the slab. Other sections in ACI 117-06 provide tolerances for special kinds of construction: slipformed elements (Section 7), mass concrete (Section 8), canal linings (Section 9), water-conveying structures (Section 10), cast-in-place bridges (Section 11), pavement and sidewalks (Section 12), chimneys and cooling towers (Section 13), and cast-in-place pipe (Section 14).
