Turnout & Special Trackwork Surveys
Detailed turnout, switch and special-trackwork surveys for construction, as-built verification and interface coordination.
What we provide
Accurate field data.
Useful project answers.
Turnouts and special trackwork concentrate critical geometry and interfaces into a short length of railway. Summit combines rail-aware field procedures, precise survey control and appropriate GEDO or total-station measurement to document the installed arrangement and support project decisions.
Deliverables
Ready for the project team.
- 3D rail and feature strings
- CAD-ready turnout as-builts
- Geometry and deviation schedules
- Plan, profile and detail information
- Control records
- Project-specific field reports
Project guidance
Detail where track geometry becomes complex
A turnout survey may need to document running rails, switch points, crossings and surrounding fixed assets rather than treating the installation as a simple centreline. Summit develops the feature list and measurement method around the design and required decision.
The work can be tied to corridor control and combined with adjacent track as-builts, clearance capture or platform and structure measurements for a consistent project record.
Typical applications

Frequently asked questions
Planning the
right survey scope.
What turnout features can be surveyed?
The agreed scope can include running rails, switch points, crossings, alignment, gauge, cant and relevant fixed interfaces. Required features are confirmed against the project design and deliverables.
Can turnout surveys be repeated during construction?
Yes. Repeat measurement can provide consistent evidence at installation, adjustment and final as-built stages, using the same control and reporting framework.
Are the outputs suitable for CAD and engineering review?
Yes. Deliverables can include 3D strings, coordinate schedules, drawings and design-comparison information in the required project coordinate system.
