An Overview of ACI 347R-14: Guide to Formwork for Concrete
Abstract This paper summarizes the American Concrete Institute (ACI) Committee 347 document, "Guide to Formwork for Concrete" (ACI 347R-14). The guide serves as a critical reference for engineers, contractors, and inspectors, providing industry standards for the design, construction, and safe use of formwork systems. It emphasizes load calculations, lateral pressure management, material selection, tolerances, and safety protocols. This overview highlights the guide's key chapters, including updates from previous editions on environmental loads and high-strength concrete formwork design. Updated references to newer plywood and aluminum beam
Scenario 1: The High-Pour Wall A contractor wants to pour a 20-foot-tall foundation wall at 8 feet per hour. The concrete temperature is 50°F. Using the outdated 2003 guide, the calculated pressure might be 1,200 psf. Using ACI 347R-14’s updated SCC and high-strength adjustments, the pressure calculates to 1,800 psf. Without the PDF, the contractor would under-design the ties and walers, leading to a blowout.
- Vertical Loads: Includes the weight of the concrete, reinforcement, formwork materials, and construction live loads (workers, equipment).
