ABOUTTHISBOOK The 2020edition oftheACIDetailing Manuai, MNL66,provides answerstomany detailing questions askedby design engineersarchitectscontractorsdetailersand enginering students.TheManual is divided in three sections: Section 1 includes a copy of ACI 315R-18, Guide to Presenting Reinforcing Steel Design Details; Section 2 includes individual details with corresponding checklists; and Section 3 includes a pilation of Concrete International articles chosen for their relevance to detailing reinforced concrete. Appendix A has tables to help the engineer in the detailing effort. to prepare reinforcing steel fabrication and placing drawings. The guide stresses the importance of this informa- presenting it in a manner that is clear and unambiguous to the reinforcing steel fabricator and placer. tion to ensure that the reinforcing steel detailer effectively and accurately captures the intent of the designer, Section 2 illustrates methods for presenting necessary design information through over 100 individual details that provide examples of ways to municate design information effectively and pletely to the contractor. The details conform to ~Building Code Requirements for Structural Concrete (ACI 318-19)* and were prepared with the U8] assistance of a task group consisting of detailers, contractors, and practicing engineers. Each detail is placed on one page with dimensionsandbarsizesleft tobepleted bythe userAlongside eachdetailnotes totheuser are LLC, listed as a reminder of the main code requirements that need to be satisfied for that particular detail. This section is planned to be interactive with the engineering munity. It is anticipated that engineers, architects, contractors, submit other relevant details to be added to future editions at techinq@. Section 3 includes a collection of 37 articles published in Concrete International related to concrete detailing that were authored by detailers and practicing engineers. The articles identify constructability issues specific to rein- forcing steel. Common problems found on engineering drawings are discussed along with solutions drawn from the experiences of knowledgeable practitioners in the industry. The article topics vary from describing the toler- topics. These solutions are not offered as official ACi-remended practice. ance cloud to addressing constraints in reinforcing bar modeling to avoiding ambiguous callouts, among other Supporting reference data in Section 4 includes specific chapters on reinforcing bars, wires, bar supports, spirals, mathematical formulas and tables, and mon symbols and abbreviations. This guide is intended to provide examples and guidance for how licensed design professionals may satisfy the prescribed provisions of ACI 318-19, Building Code Requirements for Structural Concrete. It does not, however, purport to represent the only suitable way to satisfy the requirements for every project. Engineering judgment before applying to a project.

ACKNOWLEDGMENTS A o samsue sad osa au-isn e s e ua oia go uadap a detailing questions asked by design engineers, architects,contractors,detailers, and engineering students.The structural drawings conform to the *Building Code Requirements for Structural Concrete (ACI 318-19)." ACI would like to thank the review group for this manual consisting of Chair Richard Birley, James Cornell, Jason Draper, John Hausfeld, Christopher Perry, and Tom Schaeffer. Their careful review and dedication to the project maintaining the quality expected by the industry. on top of all their other volunteer time made it possible to develop and revise this guide in a timely manner while the drawing in this detailing manual.
