Introduction to Bulk Earthworks
Bulk earthworks involve the removal, relocation, or addition of large quantities of soil or rock from a particular site to create a desired landform. This process is essential in construction projects such as building foundations, roadways, and other infrastructure developments. Understanding the fundamentals of bulk earthworks is crucial for anyone involved in civil engineering and construction.
Essential Steps in Planning Projects
