What is a whaler (also spelt waler)?

1. A. a corner brace on concrete walls after the forms are removed

2. B. a brace on concrete walls after the forms are removed

3. C. a vertical brace on concrete forms

4. D. a horizontal brace on concrete forms

The correct answer is: B. a brace on concrete walls after the forms are removed

A whaler, also spelled waler, is specifically used as a horizontal brace that supports concrete forms during the curing process and after the forms are removed. It is a structural element that helps maintain alignment and stability of the concrete walls, ensuring they remain plumb and resist lateral loads from the wet concrete. This function is critical during the pouring and setting of concrete, as it prevents deformation or failure of the walls before they gain sufficient strength. The correct understanding of a whaler highlights its role in providing essential support and stability in the construction process. While other elements like corner braces or vertical braces may serve different purposes, they do not fulfill the specific function of a whaler as it pertains to horizontal bracing within the framework of concrete forms. This distinction is important when discussing structural support systems in construction, as each component plays a unique and vital role in ensuring the integrity of the project.
