Corridor Feature Staking – SITECH CS Help Centre

Corridor Feature Staking allows you to stake specific corridor components, such as edge of pavement, shoulder, kerb, ditch, subgrade, or daylight points, directly from a corridor model at a selected station.

Start Corridor Feature Staking

From the Measurement screen, select Home > Stake.
Open the object list and select the required alignment from the Road tab.
In the Stake Method field, select Feature.
Tap ACCEPT.

Select a Station

Enter a station manually or select a station graphically from the map.
The Select Corridor Feature screen appears, displaying a corridor cross-section.
Each corridor feature is represented by a node within the section.

Select a Corridor Feature Node

Select the feature you want to stake by either:

Tapping the node directly in the cross-section view, or
Opening the node list and selecting the required node.

Finished Grade vs Subgrade Nodes

Feature names indicate whether the node belongs to the finished grade or a subgrade-adjusted surface.

Examples:

Node	Description
EP	Edge of Pavement at finished grade
SHLD	Shoulder at finished grade
EP-0.250	Edge of Pavement with a 0.250 m subgrade offset
SHLD-0.250	Shoulder with a 0.250 m subgrade offset

To enter or modify a subgrade offset:

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

Cross Section Orientation

By default:

When travelling up station, the cross-section displays left-to-right.
When travelling down station, the cross-section may appear reversed.

To change the display orientation:

Open Home > Settings > Roads (or Corridor Settings).
Select either:
- Up Station
- Down Station

This ensures the section is displayed in the direction most suitable for your workflow.

Navigate to the Stake Point

Once a feature node has been selected, Siteworks provides real-time guidance using:

Design elevation
Current elevation
Cut/fill values
Horizontal and vertical offsets
Direction of travel

The information shown in the Info Bar can be customised through:

Home > Settings > Info Bar/Panel

The guide arrow can be enabled or disabled through:

Map Options > Design

For improved visibility during staking, consider enabling:

Cut/Fill Light Bar
Cross Section View

Fine Stake Mode

When approaching the selected corridor feature, Siteworks automatically enters Fine Stake Mode.

In Fine Stake Mode:

Precision guidance arrows appear.
Remaining offsets are displayed graphically.
Screen orientation follows the selected map rotation settings.

When the stake point is within tolerance:

The centre indicator changes to solid yellow.

GNSS Guidance

Fine navigation arrows can be displayed:

North-up, or
Direction-of-approach

This is controlled through the Stakeout Guide option in:

Map Options > Design

Total Station Guidance

The orientation depends on the connection type:

Bluetooth or Cable Connection

Directions are displayed as if standing behind the instrument looking toward the prism.

Radio Connection

Directions are displayed as if standing at the prism looking toward the instrument.

Complete the Stakeout

Position the rod within tolerance.
Tap Measure.

Siteworks generates:

A Stake Marker Report
Cross-Section Storyboard information
Stake marking instructions
A graphical stake-marking diagram

The calculations are based on the configured Stakeout Settings, including stake marking method, cut/fill intervals, and working stake length.

The software also remembers the last report tab viewed and automatically reopens it for subsequent stakeouts.

Fixed and Random Station Modes

Two stationing methods are available:

Mode	Description
Fixed Station	Stake corridor features at predefined stations.
Random Station	Stake corridor features anywhere along the alignment based on your current perpendicular location.

Random Station mode is useful for:

Construction checks
As-built verification
Spot inspections
Feature location reviews

Auto Advance Options

The Auto Advance setting controls what happens after a feature is staked.

Access it through:

Home > Settings > Corridor

Setting	Result
To Next Station	Automatically moves to the next station.
To Previous Station	Automatically moves to the previous station.
No	Remains at the current station until manually changed.

The station advancement behaviour also depends on the configured Station Interval.

Tangent Point Control

You can configure whether Siteworks automatically pauses at corridor tangent points during auto-advance.

Available options include:

Setting	Behaviour
Horizontal Only	Stop at horizontal alignment tangent points.
Vertical Only	Stop at vertical alignment tangent points.
Horizontal and Vertical	Stop at both horizontal and vertical tangent points.
None	Do not stop at tangent points.

This setting is particularly useful when staking road corridors where important geometry changes occur at PI, VPI, curve, and tangent transitions.

Tip: For road construction and subgrade preparation, use a subgrade offset together with Auto Advance to Next Station. This enables fast, consistent staking of corridor features such as edge of pavement, shoulder, and batter hinge points at regular intervals along the alignment.
