Transform Your Rail Projects with Precision Surveying

High-accuracy rail surveying across Western Australia, delivering precise alignment, as-builts and monitoring to support safe, efficient and compliant possession and shutdown operations.

Track Geometry Surveys

Precision track geometry surveys verifying alignment, gauge, cant, cross-level and twist to required tolerances for safe, compliant rail operations.

  • Verify alignment, cant, gauge, and cross-level to tolerances
  • Ensure compliance with Australian rail standards
  • Provide audit-ready data for possession handback

Rail Set-Out & Construction Support

Accurate rail set-out for track, turnouts and associated works, with onsite survey support during shutdowns and possessions and seamless integration with machine control systems.

  • Precise placement of track, turnouts, and associated works
  • Integrates seamlessly with machine control systems
  • Onsite survey support during possessions and shutdowns

As-Built Rail Surveys

Reliable as-built rail surveys capturing final geometry and structure locations with accuracy, delivering CAD/GIS/BIM-ready documentation for QA, approvals and asset management.

  • Capture final geometry and structure positions with precision
  • Deliver CAD/GIS/BIM-ready documentation to client standards
  • Support QA/QC, approvals, and compliance processes

Monitoring & Deformation Surveys

High-precision rail deformation and settlement monitoring to detect movement, manage operational risk and maintain long-term safety through accurate trend reporting.

  • Detect movement, settlement, or structural creep
  • Provide assurance for operational safety and reliability
  • Track and report changes with precision over time

Culvert Construction Surveys

Accurate set-out and monitoring of rail culverts, ensuring alignment and level compliance during excavation and installation, with documentation to support QA and future maintenance.

  • Survey and set-out culvert alignment and levels
  • Monitor excavation and installation for design compliance
  • Document works for QA and future maintenance

Level Crossing Construction Surveys

Survey and set-out for level crossing construction and upgrades, ensuring smooth, safe alignment and delivering as-built documentation for compliance and authority approvals.

  • Survey and set-out for level crossing construction
  • Verify smooth alignment for safety and accessibility
  • Provide as-built documentation for approvals and compliance
Track alignment

Track Alignment & Set‑out

Precision track alignment surveys and set-out for new installations, renewals and upgrades, including cant, grade and geometry control.

Monitoring

Rail As‑Builts & Monitoring

Accurate rail as-built documentation paired with deformation and settlement monitoring to support operational safety and QA requirements.

Corridor surveys

Corridor & Bridge Surveys

Rail corridor and bridge surveys capturing topography, structure geometry and clearance data for design, maintenance and upgrade planning.

FAQs

Common questions about Rail Survey Services

Answers to the questions we hear most from WA project teams.

Do your rail surveyors hold RIW and shutdown clearances?

Yes. Our crews maintain RIW, Cat 3 medicals and competency records so they can work safely during possessions and high-risk rail environments.

How do you support tight possession windows?

We pre-establish control, plan detailed run sheets and field multiple teams so geometry checks, set-out and as-builts fit within the available access.

What outputs do you deliver for track geometry and as-builts?

Deliverables include top-of-rail strings, cant/twist reports, alignment tables, DWG/DXF, LandXML geometry and BIM/GIS datasets for asset teams.

Can you provide ongoing deformation monitoring?

Yes. We run repeat surveys and instrument critical structures to detect settlement or movement and issue alerts when thresholds are exceeded.
