The ACI SP-4 (8th Edition), "Formwork for Concrete," is regarded as the industry standard, integrating ACI 347R-14 and updating design loads to align with ASCE 7-10 and ASCE 37-14 standards. Authored by David W. Johnston, this comprehensive manual offers 18 chapters covering planning, design, and construction, featuring both ASD and LRFD methods for engineers and contractors.

Published by the American Concrete Institute (ACI), this manual—often referred to simply as “SP-4”—is the definitive guide to the design, erection, use, and removal of formwork systems. While the ACI 347 committee produces the industry standard “Guide to Formwork for Concrete” (ACI 347), SP-4 serves as its comprehensive companion handbook, bridging theoretical standards with practical application.
Appendix: useful tables, abbreviations, and resources
Formwork is the mold into which concrete is poured. If the formwork fails, the structure fails. Recognizing this, the American Concrete Institute (ACI) has published the definitive industry standard for decades: ACI SP-4, “Formwork for Concrete.”
