The process of digging near existing underground infrastructure such as gas lines, electrical conduits, or water mains. Subcontractors must locate and expose utilities safely before major earthworks begin. Requires ground disturbance permits and adherence to provincial Dig Safe or Click Before You Dig protocols.
