Volume calculation

SURFACES&VOLUME

• Multiple volume calculations can be performed and stored within the same job.

• Both the calculated results and their graphical representations are saved, allowing them to be reviewed at any time.

• To access the volume calculation page select Volumes from the Volumes page.

  

• The Volumes table displays all calculated volume computations. For each calculation, the software reports information such as the calculation method used, cut volumes, fill volumes, and other related data.

Perform a new volume calculation

• To perform a new volume calculation press New.

  

• Select the calculation mode.

  • Reference elevation: the volume is calculated between the surface and a reference elevation.

    

  • Reference point: the volume is calculated between the surface and the elevation of a reference point.

    

  • Stockpile/Pit: calculates, in reference to the reference surface, a second surface considering only the points present in the perimeter of the reference surface. Calculated is the volume between the reference surface and a second surface representing the bottom, in case of stockpile, or representing the top, in case of pit.

    

  • Reference level: the volume is calculated between the surface and a sloped plane by 3 points.

    

• Press Next.

• Depending on the calculation mode, enter the requested parameters.

Volume Relative to a Reference Elevation

• This method calculates the volume between a reference surface and a horizontal plane at a specified elevation.

  

  • Elevation: elevation of the horizontal plane used as the reference for the volume calculation.

Volume Relative to a Reference Point

• This method calculates the volume between a reference surface and a horizontal plane whose elevation is defined by a selected reference point.

  

  • Point: point whose elevation is used to define the reference plane for the volume calculation.

Stockpile / Pit Volume

• This method calculates the volume of a stockpile or excavation pit.

• The software generates a secondary surface based on the perimeter of the reference surface and calculates the volume between the original surface and the generated surface:

• For a stockpile, the generated surface represents the base of the material.

• For a pit, the generated surface represents the top reference surface.

• The resulting volume corresponds to the material contained between the two surfaces.

Volume Relative to a Reference Plane

• This method calculates the volume between a reference surface and a plane defined by three points.

  

  • Point 1: first point used to define the reference plane.

  • Point 2: second point used to define the reference plane.

  • Point 3: third point used to define the reference plane.

Calculation Parameters

• After selecting the calculation method and defining the corresponding parameters, configure the following settings:

  

  • Name: name assigned to the volume calculation.

  • Cut Swell Factor: expansion factor applied to cut volumes. The value can be entered manually or selected from a predefined list of materials.

  • Calculate Weight: enables calculation of the weight of excavated and filled material based on its unit weight.

  • Weight (t/m³): material unit weight expressed in tonnes per cubic meter. The value can be entered manually or selected from a predefined list of materials.

  • Auto Adjust Cut/Fill: available for calculations based on a reference plane. The software automatically shifts the plane vertically, while maintaining its defined slopes, until cut and fill volumes are balanced.

Performing the Calculation

• Press Calculate to start the volume computation.

• The software displays the list of available surfaces. Select the reference surface to be used for the calculation.

  

• When the calculation is completed, the software reports:

  • Total volume.

  • Cut volume.

  • Fill volume.

  • Cut and fill areas.

  • Additional calculation statistics.

• Press View to open the graphical representation of the results.

  

• In the graphical view, the color of each triangle is determined by the cut or fill difference:

  • Red: areas with maximum excavation (cut).

  • Yellow: areas with little or no cut/fill difference.

  • Green: areas with maximum fill.

• This color gradient provides an immediate visual representation of material movement across the site.

Viewing Calculation Results

• To review a previously calculated volume, select the calculation and choose Details.

  

• To graphically display a calculated volume, select the calculation and choose Details.

Deleting a Volume Calculation

• To permanently delete a volume calculation, select it from the volumes list and choose Delete.

• The calculation results and their associated graphical representation are removed from the job.
