The guide begins by clarifying what formwork includes: It distinguishes between formwork for vertical elements (columns, walls) and horizontal elements (slabs, beams, decks).

ACI 347R-14 recommends that formwork surfaces be designed to limit deflection to prevent unsightly bulges in the finished concrete.

ACI 347R-14 remains a foundational guide for formwork design. Its emphasis on safety, load prediction, and material compatibility continues to evolve with concrete technology. Practitioners should always use the current version (check for any newer edition, e.g., 347-22 if released) and pair the guide with local building codes.

The guide emphasizes the importance of proper formwork construction and safety practices, including:
