What is the importance of earthworks before the realization of a building ?

I agree with except answer >>>>>>>>>>Thanks

Earthworks can be described as "the disturbance of land surfaces by blading, contouring, ripping, moving, removing, placing or replacing soil or earth, or by the excavation, or by cutting or filling operations". (ARC, Sediment Control Regional Plan)

Soil Disturbance - The disturbance of land surfaces by any means including blading, blasting, contouring, cutting of batters, excavation, ripping, root raking, excludes normal maintenance of legally established structures, roads, tracks, and railway lines. The definition also excludes those activities that are identified as vegetation clearance activities. (Environment Waikato)

Roading and tracking activities - Earthworks associated with the formation of any new road or track or the upgrade of any existing road or track excluding normal maintenance of legally established roads and track. (Environment Waikato)

Earthworks - Any activity that exposes, disturbs, places or deposits land and soil. Such activities include, but are not limited to, tracking, roading, cleanfill sites, cut and fill operations, quarrying and mining and re-contouring. Excludes area-wide treatment (pavement overlay and strengthening) and road resealing (pavement rehabilitation) of existing roading, normal domestic gardening practises, maintenance of roads and tracks, (including railway tracks), the formation of walking tracks, cultivation (except where re-contouring is involved), maintenance of linear network utility support structures, and maintenance (including minor realignment) of existing foot tracks within public reserves and the conservation estate. (Environment BOP)

Soil Disturbance - Soil disturbance means the disturbance of soil by any means including blading, contouring, ripping, discing, root raking. moving, ploughing, removing, cutting and blasting (Hawkes Bay Regional Council)

Soil Disturbance - means the disturbance of soils by any means, including blading, blasting, contouring, ripping, root-raking, moving, removing, excavating, and cutting. Soil disturbance excludes:

• Soil disturbance as a result of vegetation disturbance activity;

• Non-motorised soil disturbance activities;

• Thrusting, boring, trenching or mole ploughing associated with cable or pipe laying;

• Soil disturbance undertaken by a mine or quarry operation which either had a currently valid mining licence, or was lawfully established, at26 April1997 (the date the Regional Soil Plan was publicly notified);

• Cultivation and grazing; and

• Foundation works for structures.

  (Greater Wellington Regional Council)

Earthworks The disturbance of soil or earth by any means including excavation (including subsurface), tunneling, drilling, infilling, land rehabilitation or restoration, stockpiling, dumping of soil or sand, and the construction/reconstruction of any track, embankment, or drainage channel. Earthworks does not include:

• Disturbing the topsoil for domestic gardening

• Vegetation disturbance that does not affect the topsoil or the root plate of trees.

• V-blading, flipping, humping and hollowing (West Coast Regional Council)

Earthworks means the excavation of, and/or filling with topsoil, subsoil, sediments, rock and/or other underlying materials on which the soil is formed. Earthworks include, but is not limited to, the construction of roads, tracks, firebreaks and landings, and ground shaping (re-contouring), root raking and blading. (Environment Canterbury)

Earthworks means modification of land surfaces by blading, contouring, ripping, moving, removing, placing or replacing soil or earth, or by excavation, or by cutting or filling operations, including the importation of fill (see definition of clean fill, provided that within the Special16 (Omaha South Development) Zone, earthworks exclude the cultivation of land and the digging of holes for the erection of posts or the planting of trees, landscaped area and gardens. (Rodney District Council)

Earthworks - "earth-moving operations carried out by any means for development purposes and includes: -(a) The removal of vegetation; (b) The disturbance of land surfaces by moving, removing, placing or replacing soil, or by excavation or cutting and filling operations; (c) contouring;(d) Road, driveway, and access construction." (ACC Operative Isthmus District Plan).

Earthworks means the alteration of land contours on any site including: (a) Disturbance of land by moving, removing, placing or replacing soil or by excavation or cutting, filling or backfilling (b) Re-compacting of existing natural ground. (Tauranga City Council)

Land Disturbance means the disturbance of land by any means including earthworks; blading, trenching, sidecutting, surface excavation, overburden and spoil disposal, ground levelling, construction of earth dams, cultivation; and the construction, maintenance, realignment or widening of roads or tracks. In respect of Chapter4- Natural Heritage: cultivation is excluded from the definition of land disturbance (Gisborne District Council).

Earthworks means "the removal, relocation or deposit of earth (which includes any substance constituting the land such as soil, clay, sand and rock) from a natural or constructed land formation. Topsoil stripping, turf farming, ground cultivation, and quarrying are excluded form the definition of earthworks": (Wellington City District Plan).

Earthworks - Any modification of land associated with subdivision or development, including excavation and filling, removing and replacing soil, contouring, cutting , levelling, deposition of cleanfill, and road, driveway and access construction (Hutt City)

Earthworks include any alteration to the land contour or disturbance of land including the deposition of cleanfill and the excavation and backfilling or re-compaction of existing natural ground, but excludes cultivation and domestic gardening. For the Residential, Commercial/Retail, Paraparaumu Town Centre and Industrial/Service zones, any earthworks associated with the construction of buildings subject to a building consent, provided all work is contained within2 metres outside the exterior foundations, shall be exempt from the permitted activity standards. The limits on earthworks in the Standards apply to any earthworks within any12 month period except in relation to overflow paths, ponding areas and the river corridor zone. (Kapiti Coast District Plan)

Earthworks means the disturbance of land surfaces by the removal or depositing of material, excavation, filling or the formation of roads, banks, and tracks. Excludes the cultivation of land and the digging of holes for offal pits and the erection of posts or poles or the planting of trees. (Queenstown Lakes District Council)

Very important. Earthworks are works created through the moving or processing of parts of the earth's surface involving quantities of soil or unformed rocks. The earth may be moved to another location and formed into a desired shape for a purpose. Much of earthworks involves machine excavation and fill or backfill.

I agree with Mr. Alex........................

It is very important before realization of a building for earthworks to commence.

Earthworks involves numerous activities under gone by small to large scale machinery.

Plant such as Excavators back hoes dozers graders tippers haulers and a lot more machinery under go numerous activities.

Blasting could also be required due to the uniformity of rock beds or strong aggregates.

The uniformity of a terrain can be ripped down and molded back up into a desired shape for strength and structure purposes.

Being able to determine the ecological impacts and the kind of material at hand is of high importance to the whole area and its surroundings.Earthworks can be your stepping stone or building block to any solid foundation or terrace and is a critical step in any process.

Before realization of the building we need at least Plane Plot - leveling, Footings / Piing, back filling, Basement. 

We can use machines  like Dozer,  Excavator. Rock Breaker and many more machinery as requirement.

Thees all operations are called earthwork. So its important before realization of the Building.
