What ACI does

The American Concrete Institute (ACI) is a 501(c)(3) nonprofit standards organization founded in 1904 and headquartered in Farmington Hills, Michigan. It develops and disseminates consensus-based codes, specifications, and technical documents for the design, construction, and materials of structural concrete, with its flagship ACI CODE-318 serving as the reference standard adopted into US building codes and used in more than 75 countries. ACI serves civil and structural engineers, contractors, educators, students, code officials, and the broader concrete industry, supported by a global footprint of approximately 40,000 members across 120+ countries, more than 90 chapters, and 371 student chapters at 113 recognized universities.

ACI's product portfolio centers on standards publications (ACI CODE-318-25, ACI/PTI CODE-320-25, ACI CODE-318.2-25, the Detailing Manual, and the ACI Collection of 300+ documents and 13,000+ pages), delivered via direct e-commerce, the ACI 318 PLUS interactive digital subscription platform, and authorized multi-user partners including IHS, MADCAD.com, Intertek, Nimonik, and BSB Edge. Complementary revenue lines include tiered membership programs (Individual, Student, Young Professional, Organizational, Sustaining), ACI University on-demand courses and certificate programs (e.g., Anchorage Design at $279, ACI 318-25 Changes course at $375 / $79 member), certification programs with quantity discounts, advertising in the 60,000+-subscriber ACI eNews, and event revenue from bi-annual Concrete Conventions and the 24 Hours of Concrete Knowledge virtual conference.

Through its wholly owned subsidiary NEU: An ACI Center of Excellence for Carbon Neutral Concrete (established 2022) and the affiliated ACI Foundation, ACI has extended its mission into low-carbon concrete research, scholarships, and resilience. Recent strategic moves include the July 2025 release of ACI CODE-318-25 with a new sustainability appendix, the 2025 launches of ACI 318 PLUS and ACI/PTI CODE-320-25, MOUs with GLOBE (April 2025) and the Resilience Action Fund (June 2026), and the May 2026 AI governance policy restricting use of generative AI on ACI standards content.

Broad incumbents

• ASTM International: ASTM International is a globally recognized private standards organization that develops voluntary consensus standards across multiple industries including concrete materials testing. It is comparable to ACI as a peer standards publisher serving engineers and materials professionals with subscription-based technical content.
• British Standards Institution (BSI): BSI is the UK's national standards body that publishes codes referenced globally, including concrete-related standards. It is comparable to ACI as a peer private standards publisher offering subscription-based access to consensus-built standards across multiple industries.
• ASHRAE: ASHRAE is a global technical society publishing standards (including ASHRAE 90.1) for HVAC, refrigeration, and building systems. It is comparable to ACI as a peer nonprofit professional society with a similar revenue model (memberships, publications, certifications, continuing education) serving building industry professionals.
• ISO (International Organization for Standardization): ISO is the world's largest developer of voluntary international standards, including ISO 9001 and standards covering concrete (e.g., ISO 22965 for concrete production). It is comparable to ACI as a peer global standards publisher with consensus-based processes, though ISO operates across all industries rather than specializing in concrete.

Direct peers

• International Code Council (ICC): ICC publishes the International Building Code (IBC) which incorporates ACI 318 by reference. ICC is directly comparable to ACI as a competing/overlapping building code publisher with a similar standards-development mission and member-based model serving code officials and building professionals.
• American Society of Civil Engineers (ASCE): ASCE is a parallel professional engineering society that publishes standards and codes (e.g., ASCE 7 for loads) referenced alongside ACI standards. It is comparable to ACI as a peer nonprofit professional society serving civil engineers with membership, publications, standards, and continuing education.
• Portland Cement Association (PCA): PCA is the US trade association representing cement manufacturers and promotes concrete construction. It is comparable to ACI as a peer nonprofit organization supporting the concrete industry through publications, education, and advocacy, with a closely related membership base and mission.
• Post-Tensioning Institute (PTI): PTI co-developed ACI/PTI CODE-320-25 with ACI and is a peer standards organization focused on post-tensioned concrete. It is comparable to ACI as a smaller, more specialized nonprofit publishing concrete-related codes, certifications, and educational content for a niche technical audience.
• National Ready Mixed Concrete Association (NRMCA): NRMCA represents ready-mix concrete producers and offers certification programs (e.g., Concrete Plant, Concrete Delivery Professional) analogous to ACI's certification offerings. It is comparable to ACI as a peer nonprofit serving the concrete industry with certifications, education, and sustainability initiatives.

Regional players

• American Concrete Pavement Association (ACPA): ACPA is the US trade association for the concrete pavement industry and offers certification, education, and technical resources. It is comparable to ACI as a peer nonprofit organization with a similar structure (memberships, publications, technical committees) but focused specifically on pavement applications rather than the broader concrete industry.
