Clearance intelligence

Rail Clearance & Tunnel Envelope Surveys

GEDO-based railway clearance surveys, tunnel envelopes and point-cloud analysis for freight and transit systems in Canada.

Rail tunnel point cloud with a clearance envelope
What we provide

Accurate field data.
Useful project answers.

Summit combines measured rail position, gauge and cant with high-density scanning to assess the space around a railway. The resulting point cloud can be evaluated against vehicle, construction or client-defined envelopes and reported by chainage.

Capabilities

Measured for the railway.

  • Trolley-mounted LiDAR scanning
  • Track-relative and coordinate-based analysis
  • Tunnel and platform clearance
  • Vehicle and structure envelope assessment
  • OCS and surrounding-asset capture
  • Repeat scanning for change analysis

Deliverables

Ready for the project team.

  • Colour-coded clearance plots
  • Chainage-based exception schedules
  • Cross sections
  • Registered point clouds
  • 3D track strings
  • CAD and engineering-ready outputs
Typical applications

Built around the asset
and the decision.
