Custom Segment Staking

Custom Segment Staking allows you to stake a user-defined corridor segment rather than an existing corridor feature node. A segment is created between two corridor feature nodes and can include an additional offset to represent construction layers, subgrade surfaces, or staged earthworks.

This workflow is particularly useful when constructing projects in multiple lifts or layers, such as:

• Road pavement layers
• Embankments
• Dams
• Building pads
• Layered earthworks
• Subgrade preparation

For example, you can stake a temporary construction layer before the finished grade is built, without modifying the original corridor design.

Define a Custom Segment

1. In the Select Corridor Feature screen, select Define Custom Segment from the drop-down menu.

2. Select the two corridor feature nodes that will define the segment.

   

   Examples include:

   • Edge of Pavement to Shoulder
   • Shoulder to Batter Hinge
   • Formation to Subgrade
   • Any two corridor feature nodes

3. If required, enter an offset for the segment.

   You can choose whether the offset is applied:

   • Vertically from the segment
   • Perpendicular to the segment

This allows you to model temporary construction layers or working surfaces below or above the finished design.

Stake the Custom Segment

After defining the custom segment:

1. Siteworks guides you to the first selected point of the segment.
2. Stake the point using the standard stakeout workflow.
3. If required, apply a horizontal offset in the same way as a standard corridor feature.

The software calculates design elevations and cut/fill values relative to the custom segment rather than the original corridor feature.

Fixed and Random Offset Options

Custom segments support the same offset functionality available in corridor feature staking.

Fixed Offset

Stake a specific horizontal offset from the segment.

Typical uses include:

• Offset construction stakes
• Safety offsets
• Working room offsets
• Survey control offsets

Random Offset

Stake any location along the segment.

When using Random Offset:

• Siteworks applies the segment grade continuously.
• Cut/fill values update in real time.
• The segment can effectively be extended infinitely left or right for staking purposes.

This is especially useful when constructing multiple layers of a road or embankment where the final width may not yet be established.

Typical Applications

Benefits of Custom Segment Staking

Custom Segment Staking allows you to:

• Stake construction layers that do not exist as corridor nodes.
• Create temporary subgrade references in the field.
• Apply vertical or perpendicular offsets without modifying the design.
• Continue staking using the original corridor geometry.
• Check cut/fill values against intermediate construction stages.

Tip: When constructing roads, dams, or large embankments in multiple lifts, create a custom segment with the required vertical offset to represent the current construction layer. This enables crews to accurately stake and verify each lift while maintaining the original finished-grade corridor design.
