Site preparation is necessary and indispensable in every project. We can no longer imagine an area where there is no parking space, green zones or other small architectural features. Road construction or site improvement activities are very specific due to the strong seasonality, and many of the processes have to be implemented according to a strict timetable. However, this area is also specific because it is very difficult to accurately estimate the quantities of materials, and even more difficult to verify the actual quantities installed. This situation is due to the fact that the construction of roads and sites is mainly based on fill soils, which have different compaction ratios and other installation conditions, which makes the calculation of the material demand more difficult.
