Requirements
The Roading Stakeout and Measurement module is required.
Key In Corridors is only available on Windows 10 controllers and is not supported on Android devices.
Prior to Siteworks v1.20, this feature was known as Key In Roads.

The Key In Corridors feature allows you to create and edit corridor alignments, build corridor templates, and generate stakeout points directly in the field. It is particularly useful for road, driveway, drainage, and civil construction projects where corridor-based design data is required.

To access the feature:

Open the COGO menu.
Tap Key In Corridors.

Available Tools

Creating a Corridor Alignment

Select the Create/Edit Corridor Alignment tool to open the corridor entry screen.

You can either:

Manually enter alignment geometry.
Convert an existing design or work order polyline into an alignment by selecting Map.

If corridors already exist in the current design, Siteworks prompts you to:

Edit an existing corridor, or
Create a new corridor.

Horizontal Alignment

The horizontal alignment defines the corridor centreline.

The first record is always the Point of Beginning (POB) and contains the starting station and coordinates.

Supported Horizontal Alignment Records

Record Type	Column 1	Column 2	Column 3	Column 4
POB	Station	Northing	Easting
Line	Azimuth	Length
Spiral In	Azimuth	Direction	Radius	Length
Arc	Azimuth	Direction	Radius	Length
Spiral Out	Azimuth	Direction	Radius	Length
Combining Spiral	Azimuth	Length

Alignment Notes

The software automatically calculates the tangent azimuth.
Calculated azimuth values can be edited if required.
Bearings can also be entered instead of azimuths. For example, S 90° W equals an azimuth of 270°.
The end station updates automatically as alignment geometry is entered.

Select Map at any time to view the alignment in plan view.

Creating a Vertical Alignment

After completing the horizontal alignment, tap Next to create the vertical profile.

The first record is always the Point of Beginning (POB) and contains the starting station and elevation.

Supported Vertical Alignment Records

Record Type	Column 1	Column 2	Column 3
POB	Station	Elevation
Arc VPI	Station	Elevation	Radius
Vertical VPI	Station	Elevation	Length
Grade Break	Station	Elevation

Vertical Alignment Requirements

The final vertical alignment station must match the end station of the horizontal alignment.
Use Map to display a profile view of the corridor.

If no active design exists, Siteworks prompts you to create a new design before continuing.

Creating Corridor Templates

Once the alignment has been created, select a station and tap the Create Corridor Template icon.

Templates define the cross-sectional shape of the corridor.

Common template components include:

Pavement layers
Shoulders
Kerbs
Batters
Drainage features
Cut and fill tie-ins

Template Building Tools

Tool	Description
Feature Code	Specifies the feature node being created.
Horizontal Distance	Distance from the previous feature node.
Vertical Distance	Elevation difference from the previous feature node.
Insert Feature Node	Creates a feature node using entered values.
Cut Tie Slopes	Defines cut batter slopes.
Fill Tie Slopes	Defines fill batter slopes.
Delete Node	Removes a feature node.
Copy Left to Right	Copies the left side template to the right side.
Copy Right to Left	Copies the right-side template to the left side.
Import Template	Loads a previously saved template.
Export Template	Saves a template for reuse.

When first entering the template editor, you choose whether you are defining the left or right side of the corridor relative to the centreline.

Tap Insert to see the edge of seal on the right side of the corridor on the cross section.

Saving and Reusing Templates

When the template is complete:

Tap ACCEPT.
Enter a template name.
Choose whether to save the template to the controller library.

Templates stored in the library can be reused on any project by selecting Import Template.

This can significantly reduce design time for standard road and drainage cross-sections.

Viewing Corridor Templates

Templates can be viewed:

In Plan View
In Cross Section View

You can also inspect templates at stations between defined template locations.

Siteworks automatically transitions between templates along the corridor, allowing changes in the corridor shape to be modelled smoothly.

Creating Stakeout Points from a Corridor

Two corridor-based point creation tools are available under:

Menu > COGO > Create Points/Arcs

Station and Offset

Create stakeout points using:

A station along the alignment.
A specified left or right offset.

Typical applications include:

Kerb stakeout
Drainage stakeout
Service offsets
Batter locations

Station, Offset and Deflection

Create stakeout points using:

Station
Offset
Deflection angle

This is particularly useful where features cross a corridor at an angle, such as:

Drainage crossings
Utility crossings
Access roads
Intersections

Best Practice

Use templates to build standard corridor sections once and reuse them across multiple projects. Combining a well-defined alignment with reusable templates can significantly speed up field design modifications, road layout, and construction stakeout workflows.
