Excavating For Foundation:
Before the actual excavation process begins, the site is “set out” using wooden pegs and strings to mark the area which is to be excavated. The level of depth will also be predetermined by the general contractor.
Excavation is the equipment-heavy task of removing the earth from the allotted area in order to make room for the foundation. Depending on the depth and hardness of the soil, the trench may need to be reinforced as earth is removed. If the earth is extremely loose, planking will be put in place to hold the sides until the foundation can be poured.
