SP-004: (8TH) Formwork for Concrete
ACI SP-4, titled Formwork for Concrete, is the definitive manual for the design, construction, and use of forms in concrete projects. Authored by the late Mary K. Hurd and updated in its 8th Edition by David W. Johnston, this guide is recognized as the "Bible" of formwork, providing a comprehensive bridge between the theoretical requirements of ACI 347R and practical field application. Core Objectives of ACI SP-4
The manual is structured around three primary goals to ensure the success of any concrete structure:
Quality: Ensuring forms are stiff and accurate enough to maintain required tolerances for size, shape, and finish.
Safety: Guaranteeing that the formwork can support all dead and live loads, including the weight of fresh concrete, reinforcement, and workers, without failure.
Economy: Minimizing costs and time through efficient planning and the reuse of formwork materials. Key Features of the 8th Edition Whether you are designing formwork for a residential
