Corridor Segment Staking

Corridor Segment Staking allows you to stake specific corridor features, such as edge of pavement, shoulder, kerb, ditch, batter hinge points, and subgrade locations, directly from a corridor model.

The stake marking methods configured in Stakeout Settings are also used for corridor staking. Catch point staking behaviour can be configured under:

Home > Settings > Catch Point Stake Settings

Start Corridor Staking

1. From the Measurement screen, tap Home > Stake.

2. Select a corridor or alignment:

   • Use the list selection icon and choose an alignment from the Corridor tab, or
   • Tap and hold the corridor directly on the map.

   If multiple objects are available in the selected area, Siteworks displays a selection list.

   

Select a Station

1. Enter the station you want to stake, or
2. Select a station graphically from the map.

Before proceeding, you can adjust corridor staking settings, including:

• Subgrade offsets
• Auto-advance station intervals
• Tangent point stops locations
• Guideline offsets
• Cross-section display settings

Select a Corridor Feature

After a station is selected, Siteworks displays a corridor cross-section showing all corridor feature nodes available at that station.

Common corridor features may include:

• Centreline
• Edge of pavement
• Shoulder (SHLD)
• Kerb
• Batter hinge
• Drain invert
• Daylight point

Each feature is represented by a node on the cross-section.

You can select a node by:

• Tapping the node directly on the cross-section view, or
• Opening the node list using the list icon and selecting it from the feature list.

Finished Grade and Subgrade Nodes

If staking finished grade, the node is displayed using its normal name, for example:

• SHLD

If a subgrade offset has been applied, the node name reflects the offset amount, for example:

• SHLD-0.250

This indicates the shoulder node is being staked 0.250 m below finished grade.

Subgrade offsets can be configured through:

Settings > Corridor

Cross Section Orientation

When travelling:

• Up Station - the cross-section displays in its normal left-to-right orientation.
• Down Station - the section may appear reversed.

You can change the display orientation through:

Settings > Corridor

to ensure the cross-section is shown in the preferred viewing direction.

Navigate to the Feature

Once a feature node has been selected, Siteworks guides you to the required point using:

• GO values
• Horizontal and vertical offsets
• Design elevation
• Cut/fill values
• Directional guidance arrows

The information displayed in the Info Bar can be customised via:

Settings > Info Bar/Panel

Additional guidance options are available through:

Map Options > Design

Recommended Display Options

For corridor staking, it is recommended to enable:

• Cut/Fill Light Bar
• Cross Section View

These tools provide:

• Visual cut/fill guidance
• Real-time corridor section updates
• Easier identification of corridor features

Fine Stake Mode

When approaching the selected feature node, Siteworks automatically switches to Fine Stake Mode.

In Fine Stake Mode:

• Additional guidance arrows appear.
• Remaining horizontal offsets are displayed graphically.
• The display orientation follows the selected map rotation settings.

When the stake point is within tolerance:

• The centre indicator changes to solid yellow.

Complete the Stakeout

1. Position the rod within tolerance.
2. Tap Measure.

Siteworks generates a stakeout report containing:

• Station information
• Node name
• Design elevation
• Measured elevation
• Cut/fill values
• Stake marking instructions

A graphical stake marking diagram shows exactly how to mark the stake according to the selected stakeout method.

Random Station Corridor Staking

Instead of staking a predefined station, you can switch to Random Station Mode.

In this mode:

• Siteworks determines the station based on your current perpendicular location to the corridor alignment.
• You can move freely along the corridor without entering station values.
• Corridor feature elevations and offsets are calculated dynamically based on your location.

This mode is particularly useful for:

• Construction verification
• Spot checks
• As-built surveys
• Earthworks inspections

Typical Corridor Features to Stake

Common corridor nodes include:

Tip: When staking road corridors, apply the required subgrade offset before selecting corridor nodes. This allows you to stake formation levels, pavement layers, and finished surface levels from the same corridor model without creating multiple designs.
