In building, what is the primary purpose of a batter board?

The primary purpose of a batter board is to outline building corners. Batter boards are temporary structures used in the construction process to provide a reference framework for setting out the corners of a building and ensure proper alignment and positioning of the foundation. They are typically constructed using two horizontal boards that are secured to stakes driven into the ground, forming a triangle shape that helps builders accurately mark where the corners of the building will be.

This configuration allows contractors to establish the layout before excavation or foundation work begins, ensuring that measurements are directly related to the intended design of the building. By using batter boards, builders can guarantee that the dimensions are correct, which is essential for the overall accuracy of the project.
