Now we will remove the top layer before building each cross section.

  1. File | Open <RoadEngCivil>\Location\Align stage 5.dsnx.

  2. Home | Assign Parameters by Range. Select the Site Prep tab (figure below).

Figure 1: Site Preparation Dialogue Set Up for Stripping
(It also an control clearing offsets)

  1. In the Overburden Removal area, Set the Depth from topo: 2. Leave the default zero offsets in the Inside tab.

  2. Set the Outside controls to Slope stake – base, Offset: 3 feet (both sides as in Figure 17‑6). This will strip 3 feet outside the template footprint.

  3. Press the Add/Edit button under the From Stn. To Stn. boxes.

  4. Press OK to accept changes and close the dialogue box. Respond OK to the re-calculate prompt.

  5. Zoom in on the cross section left or right-hand side. Notice that the stripping line is displayed (Figure 17‑6).

Figure 2: The Top Ground Layer has to been Stripped Off

The total volume of cut will have been reduced and fill increased. The OB cut volume will now be zero and there is now a non-zero Stripping volume available for reporting.

Some important facts about stripping:

  • Stripped material is excluded from the mass haul – it is assumed to be unsuitable for fill.

  • The depth stripped will be the value assigned in the Site Prep dialogue or the top surface layer thickness, whichever is least. In the above example, the top layer (OB) is only 1 foot thick so that is the stripped depth.

  • Stripping happens before the template is applied to a cross section.
