Preventing catastrophic formwork collapses, structural failures, and jobsite injuries.
), usually measured via field-cured cylinder testing or maturity meters.
Targeted advice for complex projects such as bridges, shells, mass concrete, and underground work.
Historically, a significant portion of structural collapses in concrete buildings occur during the construction phase, not after completion. Proper shoring design prevents these catastrophes. aci 34714 pdf
The official PDF of "ACI PRC-347-14(21) Guide to Formwork for Concrete" is a copyrighted document available for purchase from ACI. Due to copyright restrictions, through public websites. Many third-party sellers also list the document, often at a comparable price to ACI's own store.
The 2014 version places heavy emphasis on the cycle of shoring (supporting the fresh concrete) and reshoring (supporting the slab after forms are removed but before the concrete reaches full strength). It provides detailed calculations for determining loads transferred to slabs during multi-story construction, which is essential to prevent slab failure during high-rise construction.

The ACI 347-14 guide is organized into 10 comprehensive chapters that walk the user through the entire lifecycle of formwork from design to removal. The official table of contents from the ACI store provides a clear roadmap of the document's structure:
For any professional involved in concrete construction, procuring a copy of the ACI 347-14 PDF
According to ACI guidelines, formwork design must balance three primary, competing objectives: comprehensive guidelines for modern construction practices.
): How fast the concrete rises in the form (measured in feet or meters per hour). Temperature (
Ensuring that the molded concrete meets the structural tolerances, shapes, alignments, and surface finishes required by the project specifications.
, not a code. If an architect or engineer wants these provisions to be part of a legal contract, they must restate them in mandatory "shall" language within the project specifications. Relationship to Other Codes: While ACI 347 focuses on formwork,
ACI 347R-14 serves as a guide rather than a strict code, providing recommendations for safe and efficient formwork design and construction. This 2014 version replaced previous iterations, offering updated, comprehensive guidelines for modern construction practices.
