ACI SP-4 is a technical publication from the American Concrete Institute that consolidates best practices, design criteria, and construction guidance for formwork used in cast-in-place concrete. It addresses temporary structures that shape, support, and contain fresh concrete until it attains sufficient strength.
Shoring supports the formwork until the concrete is strong enough. The manual covers: Vertical support systems.
