A powerful machine for leveling ground is called a bulldozer. A bulldozer can be used both forward and back to level ground by the use of its massive plow on the front. A road grader is also used to level ground, The road grader uses a blade to pile the dirt up into a row beside the road and then has to back over the area in the opposite direction to flatten the pile.

If the soil is so lose that it cant hold the building even with pile foundation. So, piled raft foundation is used which make the building to float like a boat. That obeys Archimedes' principle-it is buoyed up by the weight of the earth displaced in creating the foundation.
A bulldozer or a grader.
motion
Yes, a pile of soil sitting on the ground exerts force on the ground beneath it. The soil has mass, and gravity pulls it down on the whatever is under it. A red ant standing atop the pile of soil exerts an extra force on it, to continue the figure.
A timber pile is not soil, it's a pile of timber.If a substance does not support plant growth or have the capability of supporting plant growth, it is not soil.If the timber pile decomposes to a point where the remaining organic matter can support plant growth, it would be considered an organic soil, provided the layer of organic matter was thick enough. Organic soils are known as Histosols in US Soil Taxonomy.

its depend on the soil bearing capacity
Bulldozer
it is a soil constant (coefficient of sub grade reaction)
It does not meant that pile foundation is only applicable for soft soils alone. For other type of soils it will not be much economical.
Five materials necessary for a successful compost pile are bokashi, earthworms, manure, natural soil and unpackaged food.
