Pier excavation refers to the process of digging, clearing, and preparing the ground for the installation of piers or foundation supports. Piers are structural elements used to support heavy loads, such as buildings, bridges, or elevated structures. Pier excavation involves excavating the designated locations where piers will be installed, ensuring the ground is stable and suitable for bearing the weight of the structure. This process may include removing soil, rocks, debris, and any obstructions to create a level and compacted surface for placing the piers. Pier excavation is a critical step in construction projects that require deep foundations or structural support systems.
