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.
"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.
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.
The safe height for excavation support typically depends on various factors, including soil type, excavation depth, and environmental conditions. Generally, excavations deeper than 5 feet (1.5 meters) require some form of support, such as shoring or trench boxes, to prevent collapses. The Occupational Safety and Health Administration (OSHA) recommends specific guidelines based on the depth and type of soil, emphasizing that no excavation should be left unsupported beyond these safety standards. Always consult local regulations and engineering guidelines for specific requirements.
Excavation means removing materials like soil and rock, to make a hole in the ground.
A company that lays road beds and foundations for buildings is typically referred to as a civil engineering or construction company. Specifically, they may be categorized as site preparation contractors or foundation contractors, depending on their focus. These companies specialize in excavation, grading, and other foundational work essential for infrastructure and building projects.
An archaeological site can be called many things. If it is in the process of being excavated it is either and excavation site or and archaeological site. It the site has already been excavated and has cultural significance it may become a National Heritage site.
it's a site where they dig or escavate
Construction 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.

An excavation site
An excavation site is an area where archaeological research is being conducted to uncover and study artifacts, structures, or other evidence of past human activity. Researchers carefully dig, document, and analyze the findings to learn more about the history and inhabitants of the area.
Carter is the miner that works in the excavation site, which is in the top right corner of the map. Flora works there too, and they both live in the tent near the excavation site.
It appears in the excavation site in Year 6.
An archaeologist prepares a site for excavation by conducting surveys to determine the location and extent of the excavation area, creating a research design to guide the excavation process, obtaining necessary permits and permissions, setting up an on-site laboratory for artifact analysis, and establishing proper storage and documentation procedures for recovered artifacts.
