Whenever do excavation we should consider two things. Such as the level that we are going to excavate and space needed for workers. If we don’t consider the following things then we should meet some problems. If the bottom level is excavated more than the needed level then it should backfill.
So the unnecessary excavation and backfill consumes time, money and labor. If the space is not found for workers then it is necessary to excavate again. It is trouble to excavate and consume time and workers. Excavation was done in this site by using excavator and JCB
