3D Ground Modelling and Volumetrics

Highly accurate cut and fill calculation of earthworks can be determined using ground modelling and volumetrics. This can be used to support the design process of landscape regeneration. Ground modelling turns a topographical survey, with levels and heights, into a 3D contoured or triangulated map. This provides a visual representation of the shape of the site measured.

Useful in earthworks projects, state-of-the-art software enables different planes of the site to be viewed. Volumetrics is the process by which cubic metres of land/material mass can be calculated to create a desired outcome – for example, providing accurate areas of volumes for cut/fill balancing, or creating a mound or depression in the land to suit your design needs.

Key Benefits

  • Comparing the original ground model of an area with a new ground model will show what land has been removed or added. This can be used to assist disputes regarding landfill or excavation
  • Volumetrics identifies the materials available, and the cut and fill material required, to create the desired landscape. This is helpful for landscape projects, including golf course design and areas of urban regeneration
  • To view large areas of land to be re-landscaped, remediated or regenerated, we can produce an isopachytes analysis drawing, to show areas requiring cut and fill in a colour plan
  • Accurate volume survey calculations enable earthworks monitoring during construction, ensuring that time is not wasted excavating or moving incorrect volumes of materials

We’ve engaged Powers on survey projects in the past and have always been very impressed with their efficiency and professionalism. They share our ambition and we were able to communicate directly with the owner and discuss our requirements for this complex and large scale project.
