Report on and Export REB Files (.reb)

Export REB (Regeln zur Elektronischen Bauabrechnung (rules for electronic construction accounting)) files with road data that includes corridor material volumes, corridor surface areas, corridor cross-sections, and horizontal and vertical alignment geometry. Although REB data can be separated into file formats with different numeric extensions, this exporter creates files with a single, common .reb file extension. Typically, you will import these REB files into German road design software, such as REB for Windows. You can also reimport these files back into Trimble Business Center.

Note: REB output supports vertical arcs, but not vertical curves (which are not used in Germany).

Prerequisites:

  • Licensed module; See the Subscription Plans page. For a license matrix by command, see the License page in the TBC Community. Also see View and manage licensed features.
  • Per REB format:
    • 21.003 - Corridor with engineered material layers for material volumes
    • 21.033 - Corridor with engineered a top-level finish material layer for surface areas
    • 22.013 - Two surfaces, e.g., an Original ground and a Finished design surface
    • 23.003 - Lines that define closed areas
    • DA040 - Horizontal alignment (can be associated with a corridor)
    • DA021 - Vertical alignment (can be associated with a corridor)
    • DA066 - Corridor with engineered material layers for cross-sections

To access the command:

To report on and (optionally export) data in an REB format:

  1. In the Method list, select an option:
    • 21.003 Material Volumes Report - Select this to create a corridor volume report (similar to a Corridor Earthwork Report) so that you can invoice a client. This option performs a mass earthwork analysis and computes subgrade quantities for a corridor using the average end area method between cross-sections. You can opt to export a file of the data.
    • 21.033 Linear Surface Areas Report - Select this to calculate surface areas along linear structures (e.g., for resoil, seeding, turf, etc.) so that you can invoice clients. These areas are calculated between finish material layer lines, such as sideslopes in your corridor template instructions. You can opt to export a file of the data.
    • 22.013 Prismatic Volumes Report - Select this to create a material quantities report for cut/fill zones from an isochore surface calculated using the prismoidal method. See Understanding Earthwork Volume and Isochore Calculations. You can opt to export a file of the data.
    • 23.003 Miscellaneous Calculations - Select this to calculate and report various volumes, areas, etc. based on border lines. You can opt to export a file of the data.
    • DA040 Horizontal Alignment Export - Select this to export a corridor's horizontal geometry (HAL) in REB format so that you can exchange it with clients.
    • DA021 Vertical Alignment Export - Select this to export a corridor's vertical geometry (VAL) in REB format so that you can exchange it with clients.
    • DA066 Cross-Section Export - Select this to export generated X-Sections in the REB DA066 format so that you can exchange them with clients. No HAL data is included in the file.
  2. To export a file with the raw, uncalculated REB data in addition to generating a report with calculations, check the Export data file box. For the DA040, DA021, and DA066 export options, there is no report available, so a file will be created by default.
  3. Type a path and file name for the exported file in the Filename box, or click the Browse button to browse for a location and specify a file name. By default, the file is named <your project's name>.REB.
  4. See additional steps and details for each file type below.

For 21.003 Material Volumes and 21.033 Surface Areas:

  1. In the Corridor list, select a corridor export.
  2. For corridor cross-section export, specify the interval at which to slice the corridor in the Station increment box. The first station may be odd or irregular up to the first instance of the increment specified.

    Note: The report runs along the entire length of the corridor, unless you restrict it to within a specified subsection. The accumulated volume at each station is reported.
    Tip: You can change the station format for the report in Project Settings > Units > Station.
    Note: For alignment spirals, the radius that is calculated by Trimble Business Center at each station increment is marginally different that the radius calculated by REB for Windows, but the resulting end area volumes match.

  3. To report only on a portion of the corridor, check the Only include subsection box. Then specify a station range in the Start station and End station boxes.
    The start and end station controls are disabled unless you specify a range. The disabled controls are populated with the start/end when you pick a corridor.
  4. To report on/export data for stations that are not covered by your specified station increment, check options in the Additional Stations group. Then pick points along the alignment from the coordinate control below the Other Stations list, and click Add.
    • Include horizontal alignment points - Check this to include other significant locations along the HAL, such as start and end of curves etc.
    • Include vertical alignment points - Check this to include other significant locations along the VAL.
    • Include zero cut locations - Check this box to 'slice' the corridor/generate cross-sections at points of zero cut/fill.
  5. The Materials or Layers table will change depending on the REB format you chose:
    • In the Materials table, check boxes for each engineered material you want to generate cross-section data for.
    • In the Material Layers table, check boxes for each engineered material layers you want to generate cross-section data for. These are the material layers that you create using corridor template instructions. The Position identifiers are also editable.
  6. Click Apply to run the report and create the file, if applicable.

For 22.013 Prismatic Volumes:

  1. In the Position box, enter an identifier for the calculated volume that maps to a material in an associated REB definition file.
  2. From the Upper surface box, pick the surface with the higher mean elevation in the Plan View.
  3. In the Vertical offset box, enter an offset from the original elevations of the upper surface to account for more or less volume in the isochore formation.
  4. From the Lower surface box, pick the surface with the lower mean elevation.
  5. In the Vertical offset box, enter an offset from the original elevations of the lower surface.
  6. In the KOBH box, specify the maximum height of the datum used to compute volumes against.

    Note: If a value found in the isochore calculations exceeds a tolerance set in the KOBH, KWXY, or KWZ boxes, it will be flagged as an error when data is imported into REB for Windows.

  7. In the KWXY box, specify the maximum horizontal length of a prism used in the prismoidal method calculations.
  8. In the KWZ box, specify the maximum vertical length of a prism used in the prismoidal method calculations.
  9. Click Apply. Material quantities in cut/fill zones are calculated from the isochore.

For 23.003 Miscellaneous Calculations:

  1. In the Formula list, select the type of REB data you want to calculate:
    • 21 Line length - Select this to calculate the length of a selected linear object.
    • 22 Polygon area - Select this to calculate the area within a closed line or polygon.
  2. From the Lines box, select a line, closed line, or polygon edge in the Plan View.
  3. In the Position boxes, set an identifier that maps to a material in an associated REB definition file.
  4. In the Thickness box, specify a material thickness (if applicable) to calculate a volume needed to construct the linear or area object that the selected lines define.
  5. Click Apply to create the file.

For DA040 Horizontal Alignment Export:

  1. Select an option in the Horizontal Alignment group:
    • Alignment - Select this and choose a horizontal alignment (HAL) or a corridor with an associated HAL in the list.
    • Line - Select this and then pick a line in the Plan View.
  2. Click Apply to create the file.

For DA021 Vertical Alignment Export:

  1. Select a VAL or a corridor with an associated VAL in the Vertical Alignment list.
  2. Click Apply to create the file.

For DA066 Cross-Section Export:

  1. In the Corridor list, select a corridor export.
  2. For corridor cross-section export, specify the interval at which to slice the corridor in the Station increment box.
  3. In the Station Increment box, specify the distance between stations at which you want to compute the average end area volumes. The first station may be odd or irregular up to the first instance of the increment specified.

    Note: The report runs along the entire length of the corridor, unless you restrict it to within a specified subsection. The accumulated volume at each station is reported.
    Tip: You can change the station format for the report in Project Settings > Units > Station.
    Note: For alignment spirals, the radius that is calculated by Trimble Business Center at each station increment is marginally different that the radius calculated by REB for Windows, but the resulting end area volumes match.

  4. To report only on a portion of the corridor, check the Only include subsection box. Then specify a station range in the Start station and End station boxes.
    The start and end station controls are disabled unless you specify a range. The disabled controls are populated with the start/end when you pick a corridor.
  5. To report on/export data for stations that are not covered by your specified station increment, check options in the Additional Stations group. Then pick points along the alignment from the coordinate control below the Other Stations list, and click Add.
