Simple Feature Offset

When staking a corridor feature, you can apply a horizontal and/or grade offset from the selected feature node. This provides a flexible way to stake construction offsets such as kerb back, service alignments, batter hinges, pavement edges, or temporary construction references without modifying the original corridor model.

Open the Corridor Feature Offset Tool

After selecting a corridor feature node in the Corridor Feature Staking workflow:

1. Tap the Corridor Feature Offset icon in the upper-right corner of the screen.
2. The Select Corridor Feature Offset screen appears.

Horizontal Offset Options

The second row allows you to define how the horizontal offset is applied.

Fixed Offset

Enter a specific offset distance from the selected feature node.

• A red line and offset circle are displayed in the cross-section view.
• The red marker shows the exact location of the offset point that will be staked.
• Useful when staking consistent offsets from a corridor feature.

Examples include:

• 1.0 m behind kerb
• 2.0 m outside shoulder
• 0.5 m offset from edge of pavement

Random Offset

Allows staking at any location along the corridor cross-section.

With Random Offset:

• No fixed offset distance is required.
• Siteworks dynamically calculates values based on your current position.
• Cut/fill and offset information update in real time as you move.

This is useful for inspection and checking workflows where a predefined offset is not required.

Offset Grade Methods

The third row controls how elevations are calculated for the offset point.

Define Grade

Defines a grade from the selected feature node to the offset location.

You enter a slope value which is projected from the selected corridor feature.

Examples:

This option is commonly used when staking benching, drainage, shoulders, and pavement widening.

Select Adjacent Segments

Uses the adjacent corridor segment geometry to determine the grade and elevation of the offset location.

This option is useful when the offset point should follow existing corridor geometry rather than a manually entered grade.

Select Dual Segments

Uses information from adjacent corridor segments on both sides of the selected node when calculating the offset.

This can provide a more accurate result when staking locations influenced by multiple corridor elements.

Offset From a Different Feature Node

The Stake icon in the upper-right corner allows you to select a different reference node for the offset calculation.

This means you can:

• Select one feature for display and navigation.
• Apply the offset from another corridor node.

For example:

• Stake from the shoulder while offsetting from the edge of pavement.
• Stake from a kerb line while referencing a subgrade node.
• Stake using an offset from a batter hinge point.

This provides significant flexibility when working with complex corridor templates.

Common Applications

Tip

For road construction projects, a common workflow is to select the Edge of Pavement (EP) or Shoulder (SHLD) node and apply a fixed offset with a defined grade. This allows you to quickly create stakeout points for kerbs, services, drainage, and pavement widening without modifying the corridor model itself.
