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
The ACI 347-14 document is divided into specialized chapters that address every phase of the formwork lifecycle: Aci 347-14 Pdf |verified|
Report: ACI 347.14 PDF
Introduction
ACI 347.14 is a standard that provides guidelines for the design and construction of high-strength concrete. The standard covers the materials, design, and construction of high-strength concrete structures, including buildings, bridges, and other infrastructure projects.

- Mix design and proportioning
- Construction practices, including placing, finishing, and curing
Key Provisions
Some key provisions of ACI 347.14 include:
- Materials: The standard specifies requirements for materials used in high-strength concrete, including cement, aggregates, admixtures, and reinforcement.
- Mix Design: The standard provides guidelines for mix design and proportioning, including requirements for compressive strength, workability, and durability.
- Construction Practices: The standard covers construction practices, including placing, finishing, and curing of high-strength concrete.
- Quality Control: The standard emphasizes the importance of quality control during construction, including testing and inspection of materials and finished concrete.
Benefits
The benefits of using ACI 347.14 include:
- Improved Durability: High-strength concrete structures have improved durability and resistance to degradation.
- Increased Strength: High-strength concrete can withstand higher loads and stresses, making it suitable for high-rise buildings and other large infrastructure projects.
- Reduced Maintenance: High-strength concrete structures require less maintenance and repair over their service life.
Conclusion
ACI 347.14 provides guidelines for the design and construction of high-strength concrete structures. The standard covers materials, design, and construction practices, and emphasizes the importance of quality control during construction. By following the guidelines in ACI 347.14, engineers and contractors can build high-strength concrete structures that are durable, strong, and require less maintenance.
ACI 347R-14, Guide to Formwork for Concrete, serves as the essential technical standard for designing and constructing safe, economical concrete formwork. The 2014 edition (reapproved 2021) introduced key updates, including Load and Resistance Factor Design (LRFD) for wood and refined lateral pressure calculations, while emphasizing the contractor's responsibility for safety.

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:
What is ACI 347-14?
ACI 347-14 is the definitive guide published by the American Concrete Institute (ACI) covering the design, construction, and use of formwork for concrete structures. The "14" in the title refers to the year of publication—2014. Note that as of 2025, ACI has released an updated version (ACI 347-22), but the 2014 edition remains widely referenced in existing project specifications, textbooks, and legacy contracts.
The full official title is:
"ACI 347-14: Guide to Formwork for Concrete"
This document is produced by ACI Committee 347, a group of industry experts specializing in formwork engineering. It is not a code of law in itself, but it is frequently adopted by reference in building codes (such as the International Building Code) and project specifications.

3. Shoring and Reshoring
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.
