What are wales in the context of formwork?

• A. Vertical supports for scaffolding
• B. Members in the longitudinal direction on the exterior of the formwork
• C. Cross braces used for stabilization
• D. Temporary flooring systems for construction workers

Answer: (B)

Wales in the context of formwork refer to members that run longitudinally along the exterior of the formwork system. Their primary function is to provide support and stability to the framework that holds concrete in place during the setting process. These longitudinal members help distribute loads and prevent deformation or movement of the formwork, which is crucial for achieving the desired shape and finish of the concrete once it has cured.

Understanding the role of wales is important for ensuring safety and structural integrity during construction. They play a vital part in maintaining the correct alignment and positioning of the formwork, particularly when dealing with large or complex concrete pours that require precise control over the formwork configuration.
