For example, mechanical equipment such as excavators and bulldozers may more easily damage the soil structure when carrying out earthwork. Since the soil and water loss problems caused by mechanized construction are more serious than those caused by traditional construction methods, it is necessary to evaluate the impact of mechanized construction on the ecological environment.
