Tolerances for concrete construction from ACI 117
and other industry standards developed by trade and standards-
writing organizations are discussed. Tolerances and
suggested methods of mitigating tolerance conflicts for
common concrete construction procedures and typical
construction materials that interface with or connect to
concrete elements are described. This guide is not intended
to apply to special structures, such as nuclear reactors and
containment vessels, bins, prestressed circular structures,
thin shell structures, and single-family residential construction.
Construction projects may require tolerances that are
less or more stringent than contained in this guide.
