Earthworks is a specialized skill related to the construction, modification, and shaping of the earth's surface to create landforms that meet specific project requirements or designs. It involves manipulating soil, rocks, and other natural materials to adjust the slope, gradient, and elevation of the land, and can be used in various construction projects such as roads, bridges, building foundations, and land developments. Earthworks require a thorough understanding of the soil types, environmental conditions, and technical expertise to ensure that the terrain is stable, safe, and sustainable for its intended use.
