It references standard fabrication and placement tolerances so field inspectors know what margin of deviation is legally acceptable. How to Properly Use the ACI 315-18 Guidelines
It differentiates between Engineering Drawings (created by the structural engineer to show design intent) and Placing Drawings (created by the detailer/fabricator to guide the field crew).
For decades, structural engineering offices relied on ACI 315-99. However, the rise of computer-aided detailing, advanced structural modeling, and shifts in legal liability necessitated a structural rewrite.
