Volumes
Volumes calculated from the reference alignment use end area calculation methods. If the design package volumes are generated using a different method there may be some discrepancy in the volumes calculated.
When calculating volumes Quantm projects a vertical line up or down to meet the DTM surface from the edge of the Template. The vertical line will be added to the template area used to calculate the volume in Quantm.
If the projected vertical line at the edge of the template is outside of the acceptable range set in Quantm, it will be flagged in error. This type of violation is referred to as Land Mismatch. The amount of Land Mismatch can be set in the Warning tab in the Preference settings. The default setting is 0.1 m.
Import a Reference Alignment
Click Insert / Import Reference Alignment. The Import Reference Alignment window appears:
In the Alignment file field, browse for the alignment source file.
In the Import alignment as field, enter the name for the imported alignment file.
Click OK.
The alignment format must be in LandXML for reference alignment import.
After the alignment has been found, the Alignment Import window appears:
Available Alignments
1. Select the alignment to be used as the reference alignment from the alignments found in the LandXML.
2. Click Next.
Cross-Sections
Choose the cross sections used to generate the earthwork volumes.
Bridges, Tunnels, and Culverts
You can import the location of Bridges, Tunnels, and Walls using data in the formats of:
XLS
Comma or Tab text files
The format for the file should be:
Name – Name to be assigned to the structure after import
Station – The start location along the alignment
Length - Length of the overall structure
Type - The type of structure to be created. If a structure Type is not found or doesn’t match an existing structure in Quantm a warning will appear prompting the user. The alignment can’t be imported if this occurs. The user has to exit the import and generate a matching entity in the cost parameters.
Using the browse button navigate to the file to be used to define the bridge, tunnel, wall and culvert locations.
For XLS, the following can be defined:
Sheet data is contained – Use the drop-down menu to select the sheet
Header row – Check if there is no header row present in the file. If there is a header in the file, the header titles will be assigned to the tabs in the data display table.
For text files the following can be defined:
Select the delimiter format
Comma
Tab
User-defined
Header row – Check if there is no header row present in the file. If there is a header in the file, the header titles will be assigned to the tabs in the data display table.
A preview of the information is displayed in the data display box at the bottom of the window.
Note: Culverts will not be rendered in the Quantm software.
Walls
You can import the location of Walls using data in the formats of:
XLS
Comma or Tab text files
The format for the file should be:
Name – Name to be assigned to the structure after import
Station – The start location along the alignment
Length – Length of the overall structure
Side – The side the wall will be constructed. Left or right
Type – The type of structure to be created. If a structure Type is not found or doesn’t match an existing structure in the Quantm software a warning will appear prompting the user. The alignment cannot be imported if this occurs. The user has to exit the import and generate a matching entity in the cost parameters.
Using the browse button navigate to the file to be used to define wall locations.
For XLS, the following can be defined:
Sheet data is contained – Use the drop-down menu to select the sheet
Header row – Check if there is no header row present in the file. If there is a header in the file, the header titles will be assigned to the tabs in the data display table.
For text files, the following can be defined:
Select the delimiter format
Comma
Tab
User-defined
Header row - Check if there is no header row present in the file. If there is a header in the file, the header titles will be assigned to the tabs in the data display table.
A preview of the information is displayed in the data display box at the bottom of the window.
Templates
You can define the templates at specific locations along the alignment. To import templates, you can use
the following formats:
• XLS
• Comma or Tab text files
Templates to be assigned must be created in Quantm prior to import. If the templates are not created and the templates names in the file do not match or do not exist in the Quantm software, a warning appears. If this occurs, the alignment cannot be imported. You must exit the import and create the templates in the Template editor.
The format for the file should be:
Station – The start location along the alignment
Left – The name of the template to be assigned to the left had side
Right – The name of the template to be assigned to the right hand side
Use the browse button to navigate to the file to be used to define wall locations.
For XLS, the following can be defined:
Sheet data is contained – Use the drop-down menu to select the sheet
Header row – Check if there is no header row present in the file.
If there is a header in the file, the header titles will be assigned to the tabs in the data display table.
For text files, the following can be defined:
Select the delimiter format
Comma
Tab
User-defined
Header row – Check if there is no header row present in the file. If there is a header in the file, the header titles will be assigned to the tabs in the data display table.
A preview of the information is displayed in the data display at the bottom of the window. Once the alignment has been imported, you can generate reports using Quantm’s report functionality. The alignments cannot be used for optimization or duplication in the Quantm software. Alignments imported using this method is for viewing only. If alignments are required for optimization the alignments should be imported through the Alignment Import wizard.
