The short answer...
excavation gets you to grade, over-excavation gets you below grade and is based on engineering requirements.
The longer answer...
In grading work there may be times when plans specify to cut or excavate to a particular elevation. There are other times when an over-excavation will be specified to remove unsuitable soils to a certain depth. So lets say that you are at a site where the native elevation is at 460' and plans call for finished grade at an elevation of 450' with an over-excavation of 5.' What this means is that you would excavate down 10' (from 460' to 450') and then over-excavate down an additional 5' (from 450' to 445')
At that point the bottom of the over-excavated location will usually have x number of inches to be scarified, moisture conditioned and compacted to a certain percentage of the maximum dry density obtained in laboratory testing. The removed soil (aka: over-ex or OX) will then be replaced with suitable material in lifts of a specified thickness with an optimum moisture content and compacted to a particular percentage of the maximum dry density.
Excavation means removing materials like soil and rock, to make a hole in the ground.
"Earthworks on leads" is a definition given to the process of the excavation and stockpiling process i.e. "Earthworks on leads" shall comprise of the excavation of material on the site to achieve design lines and levels detailed on the drawings and to cart, place and stockpile the excavated material in other locations on the site as designated by the Superintendent.
Setting out refers to examining the building plan. The outline of the excavation needs to be clearly understood, as does the center line of the walls.
In construction the term "unclassified" means the site contractor/GC is responsible for the onsite material. An unclassified site contract puts a great deal of risk on the contractor but is much more costly for the owner of the land.
when we undergo underground excavation ,some times it happens that cover above tunnel excavated part is not sufficient so it shows exposed surface and daylight comes inside ,such condition is called daylight condition.

Excavation is a noun and so doesn't have a past tense.The past tense of excavate is excavated.
An Eskimo snow house., A cavity, or excavation, made in the snow by a seal, over its breathing hole in the ice.
The answer depends on where in the world the excavation is to take place.
There are three main types of excavation: topsoil excavation, rock excavation, and muck excavation. Topsoil excavation involves removing the top layer of soil; rock excavation involves breaking and removing solid rock; and muck excavation involves digging soft, wet, and unstable soil.
Otzi's excavation was controversial because of its location on the border between Austria and Italy, which led to a legal dispute over ownership. There were also disagreements among scientists on how the body was handled and preserved, as well as ethical concerns about studying human remains. Additionally, some critics argued that the excavation disturbed a sacred burial site.
Yes, words ending in "ion" are almost always nouns. The noun excavation is a singular, common noun, a word for the act of excavating or the site of excavation, a thing.
Excavation season refers to the period in the year when archaeologists undertake fieldwork (normally excavation) and is most often in the summer months. There is no seasonal division in commercial archaeology, where excavation takes place year round.
