Cross Sections and Quantity

What

Use this function for the following:

To calculate cross-sections and/or quantities of selected trenches of the active Water and Sewer project.
To define the sub-surface layers of the terrain.
To define the calculation interval, intermediate stations (extra stations), terrain boundary, quantity boundaries, bulking factors, accuracy, etc., settings for calculations.

Where

Select Cross section under Calculations in the WS/Cable ribbon.

How

The dialogue box WS - Calculations will pop up. This contains a list of all the trenches available in the project.

Select the trench(es), for which cross-sections and/or quantities are to be calculated.
Multiple trenches can be selected using the key Shift or Ctrl.
Mark the check boxes Cross-sections and Quantity to calculate.
The button Settings will be enabled when a trench is selected for calculations.
Define the settings (Cross-section and Quantity settings) and click the button Build to perform the calculations.

Cross-section settings

The sub-surface layers and their respective depths for different sections (stretches) along the trench route can be defined using this button. The dialogue box Sub-surface Layers will pop up. For further details, refer the topic Sub-Surface Layers.

Quantity Settings

The basic settings for calculations are to be defined on the dialog box Settings, which will pop up with the button Settings.

Refer the respective topics (Stations, Terrain Boundaries, Elements, Quantity Boundaries, Bulking Factors, and Accuracy) for further details.
Bulking factor for calculating volumes can be defined on the tab Bulking Factors. For further details, refer the topic Bulking Factors.
Bulking factors are used to calculate the in-situ volumes of excavated soils, rock, etc.
Basically, all volumes are engineered quantities, i.e. prior to application of factors.
Bulking factors can be defined sectionwise if the bulking factors are not the same all along the length of the trench.
One can add as many sections as desired along the trench route, which are represented linewise on the tab Bulking Factors of the dialog box Settings.
If a value is defined as To station in a line, it represents that, the section between the To station value defined and the To station value of preceding line holds the bulking factor details of that line.
The value To station of the very first line indicate section from chainage 0.0 to the value defined.
The default To station value is whole section.
Accuracy can be defined on the tab Accuracy. For further details, refer the topic Accuracy.
