To stake out a station on a string

To stake out stations on a string on an RXL or LandXML road, start the survey and then follow the steps for your preferred workflow.

  • If a road consists of a horizontal alignment only, you can stake it out in only two dimensions.
  • The horizontal and vertical alignments of a road may not start and end at the same station values. When they start and end at different station values, you can only stake out points in three dimensions if their stations lie within the horizontal alignment.

If required, when staking from the plan view of the road you can stake out a position defined by nominal station and offset values. A nominal station and offset is where the station does not have to coincide with a cross section and the offset does not have to lie on a string. The offset is computed from the horizontal alignment. The elevation for the resulting positions is defined by interpolation of the cross section at the keyed in station.

  1. Tap the station.

    To select a different position, press the left/right arrow keys to select a different string and then press the up/down arrow keys to select a different station.

    To select the station from a list, tap Station and select the station. To select the string from a list, tap String and select the string.

  2. To edit the elevation, from the tap and hold menu select Edit elevation. To reload an edited elevation, select Reload original elevation.

  3. To stake out a position defined by a nominal offset , tap String and enter the offset value.

    To enter an offset to the left of the horizontal alignment, enter a negative value. To enter a nominal station value, tap Station and enter the value.

  4. If required, add the following features:
  5. Tap Start.

  6. Use the plan or cross section view to navigate to the point. See Stakeout navigation.

    If you are staking to a catch point with construction offsets, navigate to the catch point and then tap Apply to add the construction offsets. You are prompted to apply the offsets from your current position. If you are not on the catch position, select No, navigate to the catch position and then tap Apply again. To store the catch position and the construction offset, see Construction offsets.

  7. If required, you can add or edit a side slope.
  8. To stake the hinge position for a cut slope when measuring relative to a side slope, tap and hold in the plan or cross section view and select Stake cut slope hinge. This option is useful when the side slope includes a cut ditch.

  9. When the point is within tolerance, tap Measure to measure the point.

    When using a Trimble SX12 scanning total station in TRK mode with the laser pointer enabled, the Stakeout screen shows the Mark point softkey instead of the Measure softkey. Tap Mark point to put the instrument into STD mode. The laser pointer stops flashing and moves to position itself at the EDM location. When you tap Accept to store the point, the instrument automatically returns to TRK mode and the laser pointer resumes flashing. To remeasure and update the stakeout deltas, tap Measure after you tap Mark point and before you tap Accept. For more information, see EDM settings.

    Tap Store.

  10. Continue selecting and measuring points along the road, or select a different stakeout method.
  1. In the Stakeout screen, select Station and offset from the Stake field.
  2. Enter a value in the Antenna height or Target height field and make sure that the Measured to field is set correctly.

  3. To select the point to be staked out, enter the Station and the Offset.

    To enter the Station, you can:

    • Tap and select List and then select the station.
    • Key in a value.
    • Tap Sta+ or Sta‑ to select the next/previous station.

    To enter the Offset, you can:

    • Tap and select List and then select from the list.

    • Key in a value.

      Enter a negative value for an offset to the left of the horizontal alignment.

      Enter a positive value for an offset to the right of the horizontal alignment.

    • To select the next left/next right template element or the rightmost/leftmost element, tap Offs>>.
  4. Enter the Station interval.
  5. If required, enter a new elevation in the Design elevation field. To revert to the original elevation, tap and select Reload original elevation.
  6. To stake points offset from the road, leaving the roadway clear for construction, define a construction offset.
  7. Tap Start.
  8. If required, add the following features:
    • If required, you can add or edit a side slope.
    • To stake the hinge position for a cut slope when measuring relative to a side slope, tap and hold in the plan or cross section view and select Stake cut slope hinge. This option is useful when the side slope includes a cut ditch.
    • To confirm the construction of the road surface, define a cross slope.

  9. Use the plan or cross section view to navigate relative to the string. See Stakeout navigation.

    If you are staking to a catch point with construction offsets, navigate to the catch point and then tap Apply to add the construction offsets. You are prompted to apply the offsets from your current position. If you are not on the catch position, select No, navigate to the catch position and then tap Apply again. To store the catch position and the construction offset, see Construction offsets.

  10. When the point is within tolerance, tap Measure to measure the point.

    When using a Trimble SX12 scanning total station in TRK mode with the laser pointer enabled, the Stakeout screen shows the Mark point softkey instead of the Measure softkey. Tap Mark point to put the instrument into STD mode. The laser pointer stops flashing and moves to position itself at the EDM location.
