Earthwork Modeling: What, Why, and How

The Basics of Earthwork Modeling

In short, earthworks modeling takes “into account the regrading of sites to achieve development plateaus that recognize drainage levels, subsurface structures and any contamination.”

Earthworks modeling is generally the first step for engineers and architects looking to build a structure from scratch.

It not only illuminates issues that could affect the stability and safety of the building, but it also incorporates geological information, such as strata elevations, which help to develop schema for contoured surfaces and determines soil materials.

Putting the data into action allows “for calculating an optimal cut/fill balance which minimizes haul distances and material removed offsite,” as well as estimating “the quantity of surface/subsurface hard material that can be crushed to form 6F2/6F5 material that may be required for use as road/pavement areas capping, piling platforms or as structural fill.”

Earthworks modeling also aides in assessing the need for soil inversion, the burial of the non-absorbent topsoil, which reduces or eliminates the need to export soil and materials offsite.
