How to measure the construction progress rate of a selected area.

Introduction

This article provides a detailed explanation on how to measure the latest construction progress.

By comparing the base topography, current topography, and target shape, it is possible to determine the construction progress rate relative to the target shape.

Procedures and Explanation

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

2. Select 【"2" Polygon or Site】 from the annotations.
Polygon: Measurement tool for a partial area
Site: Measurement tool for the registered design data area


Left mouse click to enclose the desired area, right mouse click to exit and 【"1" Save.】
Click here to customize annotation information

3. Click 【"1" Add new measurement】 and select 【"2" Progress.】

4.  Confirm the 【"1" Initial, Current and Target.】

Calculation is performed based on the selected "Initial", "Current" and "Target".

5. Select 【"2" Heatmap or Classification】 for the displayed results

6. Click on 【"3" Calculate.】

7. The calculation results will be reflected in the tab of the created polygon.

If the heat map is not displayed, click the "▶" button to display it.

When "Heatmap" is selected in the results display.
8. Visualize the progress rate against the target terrain and the reference terrain within the target area.

When "Classification" is selected in the result display

8'．It is possible to classify according to the area of construction.
The planned amount of cut and fill can be classified only when the initial terrain is used as a reference.
