Typically, before starting earthwork or carrying out an action at the surface of the ground, clearing shrubs, plants, trees, brush, weeds and trash that might be in the field, this operation is called a punt and clearing.
Once the field is clean and free, involves the redesign and excavation begins.
Sometimes the levels of proposed ground and sub-ground poses a midifcation on the natural soil profile, being necessary in some cases to reduce those levels, and in some other cases to raise them.
In the first case 
we run a job of "cutting or excavation", and on the second "fill or embankment".
At Constructora Jod & Do we do the least possible impact to the field, so our machines: Trolleys, Back Hoe, Compactor, etc. perform the task efficiently and quickly, considering the safety of both people and the environment.
