Details and Detailing of Concrete Reinforcement (ACI 315-99)
Prepared by the licensed design professional (structural engineer). They show the overall sizes of members, concrete strengths, and the intensities/locations of forces and required reinforcement zones.
: Covers building information modeling (BIM), tolerance considerations, and drawing types. Chapter 4: Structural Drawings aci 31518 pdf
To understand the value of the 2018 edition, you must know what was revised. While the 2014 version focused on traditional detailing, introduced:
Provide complete, unambiguous general notes regarding concrete strengths, rebar grades (e.g., Grade 60, Grade 80), lap splice schedules, and clear cover. Details and Detailing of Concrete Reinforcement (ACI 315-99)
This chapter establishes the guide's objective: to facilitate the proper preparation of reinforcing steel fabrication details and placing drawings.
: To provide a bridge between the structural designer and the fabricator, detailing tolerances, bar marks, and bending details. Related Research and Technical Papers Chapter 4: Structural Drawings To understand the value

More specifically, ACI 315-18 is a guide titled "Guide to Presenting Reinforcing Steel Design Details." It was developed to help engineers and designers clearly communicate reinforcement requirements to detailers and fabricators.
This guide provides the necessary link between the prescriptive requirements of the building code and the practical, on-the-ground reality of reinforcing steel placement. It does not claim to be the only way to satisfy code requirements—engineering judgment is always necessary for unique project conditions—but it offers a proven, standardised methodology that saves time, reduces errors, and improves construction quality.
