This is the most referenced section in the PDF. It covers load calculations, including:
The guide categorizes formwork into distinct systems:
The ACI 347R-14 Guide to Formwork for Concrete provides industry standards for the design, construction, and safety of concrete formwork. It serves as a comprehensive reference covering materials, loads, and removal procedures, available for purchase as a PDF or hardcopy.

): How fast the concrete rises in the form (feet or meters per hour). The internal temperature of the concrete mix ( ∘Fraised to the composed with power F ∘Craised to the composed with power C ), which dictates setting time. aci 347r14 guide to formwork for concrete pdf
ACI works with global resellers to distribute its documents. These are excellent, legitimate sources for the PDF, often with slightly different pricing or regional availability. Examples from the search results include:
Refines lateral pressure formulas to better predict the pressure exerted by concrete, especially with the use of modern admixtures. Wind Loads: Updated to align with ASCE 7-10 standards.
The structural engineer designs for a 28-day concrete strength. The general contractor wants to strip forms at 3 days to reuse them. ACI 347R-14 provides the definitive method (using elastic analysis of shoring/reshoring systems) to determine how many levels of shores and reshores are needed. This calculation prevents a progressive collapse. This is the most referenced section in the PDF
The guide details how form lining materials and release agents affect the final appearance, from "Rough" surfaces (unexposed) to "Smooth" architectural finishes.
Help you locate a specific chapter in the . Compare ACI 347R-14 with the older 347-04 version .
ACI 347R-14 serves as the premier industry standard for the design, construction, and materials selection of formwork systems. Unlike mandatory code documents (such as ACI 318), ACI 347R is a guide . However, it is frequently incorporated into project specifications by reference, making its guidelines contractually binding on most commercial and civil infrastructure projects.

Accounts for environmental loads (wind, seismic) and construction live loads. 3. Design Allowances and Loads
ACI 347R-14 is the design and engineering standard for formwork, but it is not the only regulation that applies on a job site. It works in concert with other codes:
is a report providing recommendations for safe and effective formwork design and construction. It emphasizes the structural safety of formwork, particularly regarding the excessive deflection, collapse, or premature removal of forms, which are common causes of serious construction site accidents.
The guide specifies what information should be included in contract documents, ensuring that the engineer/architect provides enough detail to guide the contractor without overstepping into "means and methods".
