The American Concrete Institute (ACI) announced today that the printed version of ACI CODE-318-25: Building Code Requirements for Structural Concrete and Commentary is now available. ACI CODE-318 is the document that presents the requirements for the design and construction of structural concrete that are necessary to ensure public safety. It is addressed to the engineer responsible for the contract documents and the building official. As ACI’s flagship standard, ACI CODE-318-25 sets the foundation for structural concrete design and construction in buildings and nonbuilding structures. Developed through an extensive consensus process, the document addresses all major structural systems, including cast-in-place, precast, shotcrete, plain, nonprestressed, prestressed, and composite construction. This latest edition introduces significant updates, including a new sustainability appendix that reflects modern construction practices, revised requirements for post-installed reinforcing bars, and enhanced provisions for shear friction. Additional updates include improvements to deep foundation requirements across all seismic design categories and clarified guidelines for cantilever and basement wall shear design. “As the global reference standard for structural concrete, ACI CODE-318 has been adopted into building codes in the United States and is used in more than 75 countries,” said Mike Tholen, ACI senior managing director, technical operations. “The printed release of ACI CODE-318-25 makes this essential standard even more accessible to jobsite professionals, university classrooms, and engineering firms worldwide.” The 2025 edition is already accessible through the ACI 318 PLUS platform and is now available for purchase through the ACI Store. A PDF edition is also available. ACI 318 PLUS is an interactive digital platform that provides access to ACI CODE-318-25 and ACI CODE-318-19. It offers powerful in-document search, digital notetaking, and direct links to related resources. Subscribers also receive full access to the ACI Detailing Manual and the ACI Reinforced Concrete Design Handbook. ACI 318 PLUS is continuously updated as new resources and references become available, ensuring that users can always access the latest tools and advancements in structural concrete design. To learn more about ACI CODE-318 and ACI 318 PLUS, visit concrete.org/ACI318. You can also learn more by watching the new ACI CODE-318-25: Building Code for Structural Concrete video. ### For more information, contact: Brian Wheeler 248-848-3834 brian.wheeler@concrete.org About the American Concrete Institute: Always Advancing – The American Concrete Institute (ACI), a 501(c)(3) nonprofit organization, is the leading global authority for the development, dissemination, and adoption of its consensus-based standards, technical resources, and educational, training, and certification programs.
