What is the required thickness when using plywood in shoring systems?

When using plywood in shoring systems, the required thickness of 1 1/8" ensures that the material has sufficient strength and stability to support loads during construction. This thickness is particularly important because shoring often has to bear significant weight and resist the forces that can act on it, such as lateral pressures and dynamic loads.

Plywood at this thickness strikes a balance between being robust enough to fulfill structural requirements while also being manageable for installation. Thinner plywood may not provide adequate strength, resulting in a risk of failure in the shoring system, while thicker plywood could be unnecessarily heavy and cumbersome, complicating handling and installation.

In shoring applications, using materials that meet specified thickness standards is crucial for safety and compliance with building codes, which usually require specific guidelines for the strength of materials in temporary structural applications.
