Reapproval: Note that this version was reapproved in 2021, ensuring its continued relevance in the field. Typical Users Guide to Formwork for Concrete
ACI 347-14: Comprehensive Guide to Concrete Formwork ACI 347-14, titled "Guide to Formwork for Concrete," is the definitive standard for the design, construction, and inspection of formwork systems in the concrete industry. Published by the American Concrete Institute (ACI), this document serves as a critical bridge between engineering theory and job-site safety, ensuring that temporary structures can safely support the immense weight of freshly placed concrete. Overview of ACI 347-14
The guide is based on three core objectives: safety, quality, and economy. Because formwork can often account for over half the total cost of a concrete structure, the ACI 347-14 PDF provides the necessary framework to balance material efficiency with the structural integrity required to prevent catastrophic failures. Key Definitions in Formwork
Formwork: The total system of support, including the mold (sheathing), hardware, and all necessary bracing.
Shoring: Vertical or inclined support members designed to carry the weight of formwork and construction loads.
Reshoring: The process of placing shores under a stripped member after the original forms have been removed, allowing the new concrete to deflect and support its own weight.
Falsework: Temporary structures erected specifically to support work in progress, often composed of shoring and lateral bracing. Core Components of the Guide

I couldn't locate a specific document titled “ACI 347.14 PDF” in the American Concrete Institute’s current or historical catalog of standards, guides, or reports. It’s possible there’s a typo in the number, or you may be thinking of a different ACI committee document.
Here’s what’s most likely based on common ACI numbering:
- ACI 347 – Guide to Formwork for Concrete. This is the main committee document (ACI Committee 347). It covers design, construction, and safety of formwork.
- ACI 347.2R – Guide for Shoring/Reshoring of Concrete Multistory Buildings.
- ACI 347.3R – Guide for Formwork for Concrete (a shorter, earlier version).
- ACI 347R-14 – This would be the 2014 edition of the ACI 347 Report (likely the “Guide to Formwork for Concrete”). Many ACI documents use a format like “ACI 347R-14,” where “R” stands for “Report” or “Guide,” and “14” is the year.
If you meant ACI 347R-14, here is a summary of that informative paper:
ACI 347-14 vs. ACI 347-22: Should You Get the Older Version?
As mentioned, ACI updated this guide to ACI 347-22 in 2022. Why would anyone still want the 2014 version?
| Feature | ACI 347-14 | ACI 347-22 | | :--- | :--- | :--- | | Latest Research | No | Yes (new data on self-consolidating concrete) | | Digital Tools | Basic PDF | Enhanced with hyperlinks and interactive elements | | Code References | References IBC 2012/2015 | References IBC 2021 and ASCE 7-22 | | Relevance | Good for existing projects | Required for new designs under modern codes |
Recommendation: If you are working on a new design, purchase ACI 347-22. If you are troubleshooting an existing structure built between 2014-2022, or if your contract specifically calls out "ACI 347-14," then you need the 2014 edition.
What is ACI 347-14?
ACI 347-14 is an "ACI Committee Report." Unlike the Building Code Requirements for Structural Concrete (ACI 318), ACI 347 is not automatically legally binding unless it is referenced by a local building code or a project specification. However, it represents the standard of care for the industry.
The document provides guidance on:
- Structural design of formwork systems.
- Materials and fabrication.
- Shoring and reshoring procedures.
- Safety during erection and removal.
- Special considerations for architectural concrete.
5. Safety Requirements (Throughout, but emphasized in Chapter 9)
Formwork collapse is a leading cause of construction fatalities. The guide emphasizes:
- Erecting forms to withstand all loads without excessive deflection.
- Proper bracing for lateral stability (wind, seismic, vibration).
- Shoring inspection checklists before concrete placement.
Key Updates in the 2014 Version
For those familiar with previous versions (such as ACI 347-01 or ACI 347R-03), the 2014 revision introduced significant organizational changes to align with modern construction practices.
