Alignment with newer standards like regarding design loads during construction. How to Access the PDF
ACI 347R-14 (reapproved in 2021 as ACI PRC-347-14(21)) is a key technical standard covering the safe, economical design and removal of concrete formwork, including guidelines for lateral pressure and shoring. The document provides comprehensive requirements for structural safety, quality finishes, and specialized construction methods like slipforming.

Formwork must be engineered to withstand a variety of vertical and lateral loads. ACI 347.1R-14 provides standard formulas to calculate these forces accurately. Vertical Loads Vertical loads consist of both dead loads and live loads: aci 34714 pdf
Over-engineering formwork wastes expensive materials, while under-engineering invites structural failure. ACI 347-14 provides the precise mathematical balance needed for optimization.
The application of ACI 347-14 to excavation support is best understood through the lens of load path continuity. When an excavation is opened, the soil’s natural state of equilibrium is disturbed. The potential for cave-ins creates a lateral load that must be transferred to a support system. The standard’s guidance on formwork acts as a surrogate framework for understanding these lateral forces. For instance, the design of wales and struts in a trench box or a sheet pile system mirrors the design of wales and ties in a vertical concrete form.
