How to calculate the elevation value that makes the amount of cut and fill ±0 in the selected range.

Introduction

This article provides a detailed explanation on how to set up the calculation of elevation values that result in a cut-and-fill soil volume of ±0 within a selected range.
Calculating the elevation at which the amount of soil to be cut within the selected area is ±0 allows the excess soil volume to be calculated at the same time.

feature

The area for earthwork calculations is defined by the selected terrain data area.

Initially, the system automatically references the maximum and minimum elevations within the selected terrain data to calculate the earthwork balance (cut volume and fill volume) within that terrain data, determining the elevation at which the terrain becomes flat.

The calculated height can be adjusted using the adjustment bar, and recalculating the earthwork balance (shortfall/surplus) based on the change
is possible.
The range within which the earthwork balance can be adjusted is up to ±100m from the design data height.

As an example of application, when checking the progress of a construction area within a land development project, the earthwork balance is adjusted to the finished surface height, and it is also applied to calculate the required quantities.

Procedures and Explanation

1. Click on the 【"1" measurement icon】 in the side panel.

2. Select 【"2" Polygon】 from the annotations.
The "Polygon" is a measurement tool for a partial area.

Left mouse click to enclose the desired area, right mouse click to exit and 【"1" save.】

3. Click on 【"1" Add new measurement】 and select 【"2" Reference volume.】

4. Select the 【1 Measured Data】from Source then choose 【"2" Terrain or Designs】 to be calculated and click 【"3" Calculate】.

5. The calculation results will be reflected in the tabs of the polygon you created.
Click ▶ to display the heat map.

6. Clicking on 【"1" Compute cut and fill balance】 to set the amount of soil cut and fill to zero within the selected area.

You can change the 【"2" Compaction coefficient.】
