2.2 Create an Excavation Plan

How to create an excavation

In this tutorial you will learn how to create a detailed excavation plan.




  • The excavation tool creates an editable volume, the "excavation boundary", to manipulate through operations such as cuts, fills, and ramps
  • Access the excavation tool from Excavation, on the toolbar
  • The Excavation menu is comprised of two tabs:
  1. Add Operations - make cuts, fills, and ramps
  2. Excavation Plan - view and edit operations per milestone, edit excavation boundary and settings, and view and export the excavation breakdown


1. Excavation Operations

Cut and Fill:

    • Go to Excavation
    • Under Add operations, select Cut to remove material, or Fill to add material
      • Add anywhere on the map (and the boundary will appear)
        • Alternatively, under Excavation Plan, click Create Excavation Boundary
      • Click points with polyline tool to create a polygon (3 points min.)
      • Click Done
    • Cut/Fill Menu -
      • Define the cut depth (or fill height) by inputting an elevation, or by adjusting top or bottom sketch elevations
        • Simply minus the depth or add the height from zero for a flat map Eg. -3 [m]
        • Use a sea-level elevation for a topographic map Eg. 42 [m]
        • Find and use the local sea-level elevation by clicking Select From Map
      • Check Slope Walls to angle all the walls of the cut/fill
        • Slope inwards or outwards from the sketch
        • Define the slope ratio (Apply to all or set ratio for each slope)
        • Selective slope walls

    • Go to Excavation
    • Under Add operations, select Positive Ramp or Negative Ramp
      • Note: Ramps are only available after making a cut or fill
      • Position the ramp along the wall of a cut or fill
      • Click Done
    • Ramp Menu -
      • Define width, height, and percent grade (slope)
      • Define calculation type
        • Left unexcavated - ramp volume will be subtracted from the total bulk excavation volume
        • Backfilled - ramp volume will be added as a fill volume
      • Define stable soil angle (side-wall slope)
        • Enter x-y slope ratio or '0' if a lateral slope is not required



2. Excavation Plan

  • Go to Excavation, and then Excavation Plan
    • See the excavation operations listed and separated by milestone
  • On the operation card, click on the three dots to see options, such as:
    • Edit Details - reopen the cut/fill edit menu to adjust the operation
    • Duplicate - make a copy of the operation, which can be dragged to move
    • Create fill from cut - to use the shape of a cut to create a fill
    • Move operation
    • Delete Operation


Editing Excavation Settings:

    • Under Excavation Plan, Click Edit Excavation Settings
    • Here you can edit the sketch of the boundary, and change the color of the boundary or excavation operations
      • Existing Grade - Calculated sea level of initial excavation surface
      • Boundary Surface - Select default texture or color for the area surrounding the excavation operations
      • Excavation Color - Select default texture or color for the excavation operations areas
      • Edit Polyline - Use polyline tool to edit excavation boundary sketch


Earthwork Takeoff:

    • Under Excavation Plan, click Earthwork takeoff
    • Here you can view and export a breakdown of the excavation operations performed to date
      • Overview tab -
        • Swell Factor - percentage adjustment representing the increase in volume
        • Project total cut - calculated compact and loose volumes of cuts
        • Project total fill - calculated compact and loose volumes of fills
        • Milestone Breakdown - summary of milestones and volume of materials used
        • Export breakdown as a .csv file
      • Detailed Breakdown tab -
        • Tabular breakdown of each element, occurring milestone and volume used
        • Export breakdown as a .csv file
