What does construction of a building start with? Construction of any building usually starts with excavation. Excavation is a process necessary for the construction of every modern building.
It is a well-known fact that there exist different kinds of soil. It is also known that the structure of the soil is of great importance for excavation. The foundation of a building should never be placed on organic soils because soils of this kind are easily decomposed. They are decomposed because water and wind change their structure. So, if the upper stratum of soil is organic, it must be removed from the construction area in order to guard the foundation of the building against water and wind erosion. Further excavation may take place only after the upper organic stratum has been removed. In colder climates the foundations should be placed below the level to which the ground freezes in winter.
