What is the purpose of batter boards in masonry work?

Batter boards are primarily utilized in masonry work to accurately locate points after excavation. When initiating a construction project, batter boards are set up around the perimeter of the proposed structure. These boards provide a way to create reference points for the layout of walls, foundations, or other elements of the building. They enable the mason to mark precise measurements needed for the construction, ensuring that everything is aligned correctly with respect to the design specifications.

By positioning the batter boards at specific distances and using strings tied between them, workers can easily visualize and maintain the intended layout even as soil is moved or other site preparations take place. This approach is crucial for achieving accurate dimensions and avoiding mistakes that could occur if measurements were based solely on excavation marks, which may not remain visible or consistent.

The other options, while related to construction, do not accurately reflect the specific function of batter boards in the masonry context: they do not primarily enhance wall strength, provide structural support, or control water drainage, all of which are roles played by other tools or methods in masonry and construction practices.
