Introducing changes to the existing topography may be difficult or even impossible for various reasons. For example, you shouldn't make major changes to the vicinity of large trees, because they always have an adverse effect on the growth and development of these plants.
Lowering the height of the ground is often impossible due to the existence of various underground utilities in a given place or the presence of bedrock difficult to detach in the ground.. Low groundwater levels or the presence of blackwater are often the reasons for limiting the depth of excavation.
Carrying out earthworks, in which significant volumes of soil are obtained, requires proper management. If the excavated masses of land cannot be used in the area, a significant reduction in works should be sought. Also, do not design large changes in configuration, if it requires the delivery of significant amounts of land to the designed embankments. As can be seen from these reservations, always when designing earthworks, it is necessary to strive to equalize the volume of excavations and embankments, that is, to balance them.
Works related to shaping the land surface are always performed on the basis of a design and specially prepared design and cost estimate documentation. Such documentation consists of a technical and working project. topography depicting with the help of contour lines, elevation ordinates or other markings, the existing condition and the planned shape, as well as calculations of the volume of earth masses from excavations, required volumes needed to create the designed embankments and to indicate the most economical direction of movement of soil masses from excavations and other data depending on the size and type of earthworks carried out.
