Custom Feature Staking

Custom Feature Staking allows you to create and stake a point that does not exist as a standard corridor node. Instead, Siteworks calculates the intersection between selected corridor elements and creates a custom stakeout location.

A common example is staking the point where a subgrade surface intersects a tie slope, but the workflow can be used for other custom corridor geometry intersections.

Define a Custom Feature

1. In the Select Corridor Feature screen, choose Define Custom Feature from the dropdown menu at the top of the screen.

2. Select the two corridor feature nodes that define the first segment. This is commonly the subgrade segment.

   If a subgrade offset is required:

   • Tap the Corridor Settings icon, or
   • Navigate to Settings > Corridor

   Then enter the required offset amount and direction.

3. Select the second segment that will intersect the first segment, such as a tie slope.
4. If required, enter a vertical offset for the selected segment and choose how the offset is applied:
   • Vertical Offset – Applied vertically from the segment.
   • Perpendicular Offset – Applied perpendicular to the segment.

Locate the Custom Feature

Once the geometry has been defined, Siteworks calculates the intersection point and displays it as a green stakeout circle on the corridor cross-section.

Examples include:

• Subgrade to tie slope intersections
• Offset subgrade transitions
• Custom batter intersections
• Pavement layer intersections
• Drainage feature intersections

Stake the Custom Feature

After the custom point has been created:

1. Select the calculated stake point.
2. Follow the normal stakeout guidance.
3. Use the Info Bar values, guide arrow, cut/fill information, and Fine Stake guidance to navigate to the location.
4. Tap Measure once the point is within tolerance.

A standard stakeout report and stake-marking diagram are generated in the same manner as any other corridor feature.

Apply Additional Horizontal Offsets

Custom features support the same horizontal offset functionality available for standard corridor features.

You can:

• Apply a fixed horizontal offset.
• Apply a random offset.
• Define an offset grade.
• Stake from an alternative reference node.

This provides additional flexibility when staking construction offsets from the custom feature location.

Common Applications

Tip: Custom Feature Staking is particularly useful when a required construction point is not explicitly defined as a corridor node. Instead of modifying the corridor model in the office, you can create the required intersection directly in the field and stake it immediately.
