With Propeller, you can compare your current survey to a design surface. The cut/fill components of the takeoff report will help to determine the amount of material removed since your last survey and how much material is needed to complete the project.
Creating a Takeoff Report
Select the SITE and SURVEY from the drop-down menu within your portal.
Select the OUTPUTS tab, and choose Takeoff Map under the MAPS section.
A grid will appear, covering the entire existing site. You can size the grid by dragging the corners in and out. You can also pan the map to the location you want on the Takeoff map.
Select the design you want to compare from the Design drop-down menu.
Please note: a Takeoff report cannot be calculated without first choosing a design, and it is not currently available for pre-processed data.
Choose the grid size you want to view on your Takeoff Report.
The processing times will depend on the grid spacing and the size of the overall takeoff map selected. To increase performance, we recommend exporting smaller areas separately if you are working with a large site. For example, a large area with small grid spacing will take longer to calculate than a smaller area with similar or larger-sized grid spacing.
You can also change the colors and values of the heat map. Select the color block to adjust the color scheme or type in the heatmap increments of measure. Select APPLY.
To add contours, choose the MINOR and MAJOR value and color—black or white— to display on the map.
Survey layers
If you want to see your entire site's elevation or contour lines in the Takeoff Report, you can turn those on in the SURVEY tab.
Exporting the Takeoff Map
Once satisfied with the preview, select the paper size in the drop-down menu. Size options are organized by standard international sizes and standard U.S. sizes. Click EXPORT TAKEOFF MAP.
Depending on the size and detail of your Takeoff map, it may take several minutes to render. Once finished, a preview and the option to print will appear.
Once ready, the Takeoff map will automatically open.
You can choose to print it or save it as a PDF.
Reading the Takeoff map
Each grid has a crosshair noting where the measurement was calculated. It shows the amount of cut, fill, and material moved for that location.
The report will also contain additional information in the legend, including:
Site name,
Surface comparison file,
Date of the survey,
The person who created the report,
Date created,
Area summary with cut, net, and fill totals for the area within the grid you set for the takeoff map,
A legend noting the heatmap colors.
