What is a grade line in construction-related contexts?

The grade line refers to the soil surface where it intersects with a building, specifically indicating the level of the ground around the structure. Understanding the grade line is essential for various construction activities, including excavation, foundation placement, and ensuring proper drainage away from the building. It helps establish a baseline elevation from which various measurements and construction details are determined.

By using the grade line as a reference point, builders can ensure that the foundations are laid at appropriate depths and that water management systems can be effectively designed to prevent moisture intrusion. This concept is crucial in ensuring that buildings are constructed safely and effectively in relation to their surrounding terrain.
