Process Overview

  1. Create the earthwork file
  2. Create sample lines for volume calculation
  3. Compute materials through project
  4. Create detailed reports from computed materials for individual earthwork divisions throughout the project
  5. Create a summary report that summarizes the earthwork quantities from all detail earthwork divisions
  6. Include all Earthwork reports in the construction data packet
    1. FDM 19-10-43.5 PS&E Transmittal and Composition (wisconsindot.gov)
  7. Include the Detail Reports in the 09-Earthwork Data area of the plan
    1. FDM 15-1-40 Earthwork Data Sheet
    2. Earthwork quantities sheet
  8. Include the summary report in the 03-Miscellaneous Quantities area of the plan.
    1. FDM 15-1-30 Miscellaneous Quantities
    2. Miscellaneous quantities sheets

Average end area volume

Volume is calculated by determining the section areas at sample lines and calculating an average between adjacent sample lines. The average section area is then multiplied by the distance between the lines to calculate volume.

Volumes in intersections

Sample lines will be shortened so that they do not overlap and quantities are not double counted.

Exercise files qnty-erthwrk-03-data-c3d22.zip

To calculate earthwork, Civil 3D uses sample lines to capture the average end area and perform the earthwork calculation. When not within the limits of an intersection, It is best practice the sample lines match the exact locations and widths as the cross sections. Within the intersection, because of the varying geometry of the roadway, the frequency of sample lines should be increased so a more accurate calculation of earthwork volume can be made.

Match lines are used in Civil 3D when sample lines from separate alignments intersect (intersections, ramps, loops at interchanges) and are used to automatically establish limits for sample lines within intersections so the sample lines do not overlap. For complex intersections and interchanges, these match lines are also shown on the earthwork match line detail sheets. Per FDM 15-1-20.5 Interchanges and complex intersections should have earthwork match line details for use in computing cut and fill yardage. Refer to Earthwork matchlines sheet for tips to create the earthwork match lines sheet.

Establish intersection limits

qnty-erthwrk-03a.mp4 3:55

Before match lines are created, create drafting lines that represent the extents of the intersection. The intersection extents will assist in the creation of match lines and will help establish where the sample line frequency must be increased. The drafting lines will be perpendicular to the sideroad alignment located at the end of the curb furthest from the intersection. Another set of drafting lines will be perpendicular to the main road alignment located at the furthest extents of the intersection.

  1. Set active layer to P_MISC_Text
    1. WisDOT Sheets Tab > Annotation Panel > Set P_MISC_Text
  2. Draw lines perpendicular to the sideroad alignment at the curb return limit furthest from the intersection
    1. Home tab > Draw Panel > Line
      1. Select the end of the curb return furthest from the intersection.
    2. Shift > Right Click > Perpendicular Snap
      1. Snap the line perpendicular to the sideroad alignment
    3. If applicable, repeat on the other leg of the sideroad.
  3. Draw lines perpendicular to the main alignment at the curb return limit furthest from the intersection
    1. Home tab > Draw Panel > Line
      1. Select the end of the curb return furthest from the intersection
    2. Shift > Right Click > Perpendicular Snap
      1. Snap the line perpendicular to the main alignment
    3. Repeat on the other leg of the mainline alignment
  4. Extend the lines past the intersection limits so each line intersects with the adjacent line
    1. Select the lines
    2. Hover over one of the end grips > Lengthen
      1. Extend the first end past the intersection limits (furthest curb return on either side of the mainline)
    3. Hover over the other end grip > Lengthen
      1. Extend the second end past the intersection limits (furthest curb return on either side of the mainline)

    4. Repeat for all intersection limit lines

Establish normal sample line width

qnty-erthwrk-03b.mp4 4:06

To further aid in the creation of earthwork match lines, create offset alignments that represent the width of the sample lines that are used to create the cross section sheets. The intersection of these offset construction alignments represents where the sample lines from the roadways will start to intersect if match lines are not created.

Info: Setting the alignment offset depends on overall roadway width. Best practice is to mimic the sample line widths that were used on the cross section sheets. See Cross section sheets basics. Normal symmetrical roadways will have the same incremental offset on left/right (150/150 for a 1IN:20FT scale, 75/75 for IN:10FT scale).

  1. Home Tab > Create Design panel > Alignment > Create Offset Alignment
  2. Select mainline alignment
  3. Create Offset Alignments dialog
    1. Offsets name template: <[Parent Alignment Name]>-ML-Develop-<[Side]>
    2. No. of offsets on left: 1
    3. Incremental offset on left: 180

    6. Alignment Style: ALI Construction Line
    7. Alignment label set: _No Labels
    8. OK

  4. Repeat for sideroads

Create match lines

qnty-erthwrk-03c.mp4 5:47

Create match lines that will be used as targets when creating sample lines. When creating match lines, three things need to be analyzed to help determine exact positioning of the match lines: intersection limit lines, sample line width construction alignments, and design surfaces. The intersection limit lines and sample line width construction alignments are just there for guidance; adjust the position of the match lines to best fit the design surfaces.

Sample line locations outside of intersections should match the exact locations of cross sections. Therefore it is recommended to use the sample lines as established in the cross sections, utilizing data shortcut reference.

Per FDM 15-1-45, the normal cross section interval is the station (100 ft). A 50-ft interval is often used on urban projects. Additional cross sections should be provided at special locations like driveways, culverts, horizontal geometry changes, and critical superelevation changes.

Create data shortcuts for sample line groups

  1. Open the cross section file(s) ProjectID\sheets\090201-xs.dwg
  2. If the data shortcuts project is not set, set the data shortcuts project:
    1. Data shortcuts
    2. Toolspace > Prospector > Right Click Data Shortcuts > Set Data Shortcut Project
    3. Set the data shortcut project to the active design Civil 3D Project
    4. If the project does not appear, you may have to set the Working Folder
  3. Check/adjust sample line group name (optional)
    1. If desired, adjust the sample line group names to reflect their intended usage
    2. Toolspace > Prospector > Expand Centerline Alignments > Expand Alignment Name > Expand Sample Line Groups
    3. Right Click the sample line group > Properties > Information Tab
    4. Set the sample line group name as desired: SLG-XS-RdwyName
  4. Create data shortcuts for sample line groups
    1. Toolspace > Prospector > Right Click Data Shortcuts > Create Data Shortcuts
    2. Select the checkmark next to each sample line group
    3. OK

Create promoted data shortcut references to sample line groups

qnty-erthwrk-05.mp4 5:42

Exercise files qnty-erthwrk-05-data-c3d22.zip

Typically, we want to create data shortcut references for most objects. In this case with sample line groups, we essentially want to copy the sample line groups from the cross section file into the earthwork file as modifications to the sample frequency are required at intersections. In this workflow, instead of using Create Reference, we will Promote the sample line group data references.

  1. Open ProjectID\dsg\qty\ewrk\ewrk-< roadway>.dwg
  2. Toolspace > Prospector > Data Shortcuts > Expand Alignments > Expand Centerline Alignments
  3. Expand a centerline alignment that contains cross sections > Expand Sample Line Groups

    1. Right click the Sample Line Group > Promote

  4. Create Sample Line Group Reference
    1. Deselect any unwanted Data Sources
      1. Corridors
      2. Pipe Networks
      3. Surfaces

    2. Set display styles for each surface. This is useful if desired to create cross sections to view the earthwork materials as calculated.

      Surface Recommended Section Style
      Exist EX Ground
      Rfnt-All-Datum Final Datum
      Rfnt-All-MarshExcLimits Marsh
      Marsh-Bottom Marsh Bottom
      Rfnt-All-Marsh-Waste-Limits Marsh
      Rock Rock
      Rfnt-All-EBS EBS
      Rfnt-All-Subg-Impr SubgImpr

      Info: In the Create Sample Line Group Reference dialog, the data sources to sample list will display both data shortcut referenced objects in the current drawing and objects that are sampled in the source (cross section) drawing. Deselect all objects from the source drawing as the objects referenced for earthwork already exist in the current drawing and don't need to be re-referenced.

    3. OK

  5. Repeat for all centerline alignments that contain cross sections

Remove unwanted sample lines

There may be certain sample lines from the cross section files that are not required for earthwork. Since the sample line groups were promoted in the last step, these un-needed sample lines can be deleted. Examples are as follows:

  • Sample lines within the intersection limits

    • These sample lines can be deleted as they do not fit within the matchlines created earlier in this topic. They also do not meet the frequency required for earthwork computations in intersections
    • Delete all sample lines on both mainline and sideroads within the limits of the matchlines developed earlier.

  • Skewed culvert pipe sample lines

    • A skewed sample line will result in inflated earthwork numbers

To delete:

  1. Select all sample lines to be deleted
  2. Del

If it is not desired or possible to copy the sample line groups from the cross section file to the earthwork file, the sample lines can be created from scratch. The sample lines in the earthwork calculations should match the exact location of the cross sections that are shown in the plan. Per FDM 15-1-45, the normal cross section interval is the station (100 ft). A 50-ft interval is often used on urban projects. Additional cross sections should be provided at special locations like driveways, culverts, horizontal geometry changes, and critical superelevation changes.

Create sample lines tip: Extend matchlines in acute angle intersections to minimize sample line overlap

In acute intersections, extend the matchlines beyond the intersection point of the drafting polylines to allow for automatic sample line width generation in areas outside of the Curb and Gutter.

To utilize the matchline extension, in the Create Sample Lines - By Station Range dialog, the matchline can be targeted and a swath width can also be assigned. In this case, if the matchline is not seen by the sample line it will follow the width set in the create sample line dialog.

  1. In the Create Sample Lines - By Station Range Dialog, first set the Left and Right Swath Width to the desired normal width
  2. Then, set Snap to an alignment to True

  3. Select the desired matchline alignment

    1. When the matchline alignment is found, the sample line will stop at that alignment.
    2. When the matchline alignment is not found, the sample line will go to the swath width as prescribed.

The WisDOT Excel add-in must be installed to run the earthwork summary report. For external partners, the WisDOT Excel add-in is available on the WisDOT Civil 3D file descriptions (wisconsindot.gov). Internal users should see Autodesk Civil 3D 20XX -Excel Add-In in Software Center.

More info on the WisDOT Earthwork Summary Report: Excel - Earthwork Summary Report

The second step in the creation of the earthwork report, after creating the earthwork detail reports, is to create the earthwork summary report. This topic uses the Earthwork Summary Report available in the WisDOT Excel Add-In. If the WisDOT Excel add-in is not available to the user, the Legacy Earthwork report process (below) is still applicable.

  1. Open Project ID\dsgn\qty\ewrk\ewrk-<mainroadway>.xlsx

  2. WisDOT Civil 3D Tab > Reports Panel > Earthwork Summary

    1. Detail Sheet Selection
      1. All earthwork detail worksheets in the workbook will populate. Select/deselect which sheets to include.

Changes to expansion factors

If modifications are required for the expansion factors, the earthwork process does not need to be re-run. Simply modify the expansion factor in the headers of all earthwork details and the earthwork summary sheets.

Unusable/Salvaged Pavement

The unusable/salvaged pavement column E on the earthwork detail sheets will default to 0 for each row. Users are required to manually enter the cross sectional area for each station throughout the corridor.

  • Option A: For consistent cross section roadways, it may be as easy as calculating the cross sectional area for one section and copying that value to the rest of the rows.
  • Option B: For irregular pavement cross sections another more complicated workflow utilizing the earthwork process to calculate unusable/salvaged pavement may be required.
    1. Create a second Drawing in ProjectID\dsgn\qty\ewrk named Unusable Pavement.dwg
    2. Create a polyline that wraps the existing pavement surface. This will be used as an outside surface boundary
    3. Data reference the existing surface
    4. Create a new surface in Unusable Pavement.dwg
    5. Paste the existing surface into the new surface
    6. Add the boundary polyline as an outside surface boundary
    7. Lower the surface (Edits) by the pavement depth. This surface represents the bottom of the existing pavement
    8. Data shortcut reference all sample line groups from the original ewrk-rdwy.dwg
    9. Run the earthwork report process using the new pavement bottom surface as the datum surface and the existing surface.

    10. Copy the "Cut" column from the pavement bottom earthwork process to the Ewrk-Rdwy.xlsx - Unsuable/Salvaged pavement column.

    Tip: (Option B) If the pavement depth varies, create multiple unusable pavement surfaces depending on the pavement depth. Then create one final surface and paste all unusable pavement surfaces to create one complete unusable pavement surface.
