Calculating Layerwork Volumes

This Tech Tip explains how to calculate layerwork volumes.

Solidifying the Layerworks

The first step is to solidify the layerworks, this function converts the layerworks in the road template into road layers.

Section Menu › Solidify Layerworks


Dialog in Version 6.3


Dialog in Version 6.4 (note the additional graphics to make the options easier to understand)

Start chainage Enter the first chainage in the range of chainages to process.
Stop chainage Enter the last chainage in the range of chainages to process.
Batter layer Select the layer that was generated using a template.
Initial destination layer Select the first layer on which to create generated cross sections. This layer will be used for the first layerwork definition. Subsequent layers will be used for subsequent layerwork definitions. For example, if you specify Layer 3 as the initial layer and there are three layers in the layerworks definition, then layers 3, 4, and 5 will contain the generated cross sections. These layers will be renamed to the Layerwork descriptor value specified in the Template Editor, if they were not renamed manually.
Include outside points from Batter layer for: This option is used to include points in the batter layer cross section that lie outside the layerworks in the generated layer. See the illustration below.
Step in Fill Only This option is only available if "Only last layerwork detail - stepped" is checked. If this option is checked then the layerworks will only be stepped when in fill. In cut situations a box cut, with a width equal to the first layerwork in cut, will be created.
Try to intersect with batters: Left and/or right This option is not available if the "None" option is checked. If one of these options are checked you must specify a ground layer. Check these options to have the routine try to intercept with the batter slopes on the respective sides..
OK Button Click this button to accept the current entries in the dialog.
Cancel Button Click this button to cancel the function.

Once the layers have been solidified, the road cross section can be viewed with the additional layers.

Section Menu > Graphical Edit

With the cross section shown.

Section Menu > Layer Details


The new road layers can be selected and displayed (Note: the names are the names used in the road template). Once the layers have been solidified, areas have to be recalculated.

Re-calculating of Areas

Area/Volume Menu > Recalculate Areas


I want to calculate the volume between layers "Ground" and "G5 Natural gravel", the areas will then be calculated between these 2 layers. If the output window is show, the calculated areas will be shown in the output window.

Calculating the Volumes

Area/Volume Menu > Masshaul Volumes


Make sure the batter layer selected, is the same layer used for recalculating areas.

Click OK to calculate the volumes


Click Print Results to have the final results displayed, saved to a file or printed.
