Published by the American Concrete Institute (ACI), this standard is the industry baseline for preparing structural drawings and the associated "placing" (or shop) drawings. Its primary goal is uniformity. Because reinforced concrete is used globally, a standard language of symbols and notations is required to prevent costly, dangerous errors.
The "-18" designation indicates that this version was published in 2018, superseding the previous 1999 edition. This update was significant, as it modernized the standard to align with major changes in ACI 318-14 (Building Code Requirements for Structural Concrete).
