3D Laser Scanning for Civil & Infrastructure | Australia

Infrastructure assets need geometry that matches field conditions: bridge soffits, culvert invert levels, road corridors, retaining walls, and drainage networks. Traditional pick-up is slow on complex structures. Laser scanning captures millions of points in hours, giving engineers a complete record for assessment, design, and asset management.

Brisbane Point Cloud supports consultants and contractors on SEQ transport projects, water infrastructure, ports, and regional bridge stock. We combine terrestrial scanning for structures with UAV LiDAR or photogrammetry for corridors and terrain.

Time on the carriageway is the constraint that shapes most civil jobs. Drone LiDAR captures a road, its batters, drainage, and adjacent terrain in one flight, keeping crews off live lanes, while terrestrial scanning from the shoulder or a closed lane handles structures in detail. Everything is tied to your control network and the MGA2020 datum with levels on AHD, then exported as classified LAS, LandXML surfaces, and DWG sections that drop straight into 12d or Civil 3D. Independent check points verify the result so the data stands up for design, condition assessment, and progress measurement.

Challenges

  • Limited access windows on live roads and rail corridors
  • Complex geometry on bridges, culverts, and retaining structures
  • Integration with existing survey control and GDA2020 datums
  • Vegetation and water limiting line-of-sight on corridors
  • Deliverables required in CAD, GIS, and point cloud formats

How we serve this sector

  • Bridge and structure scans for condition assessment and load rating inputs
  • Road and rail corridor mapping with drone or mobile capture
  • Topographic surveys for earthworks and drainage design
  • Tunnel and culvert internal geometry documentation
  • Export to LAS, DXF, 12d, and Civil 3D compatible workflows

Typical projects

Bridge deck and soffit condition survey
Road upgrade corridor topographic mapping
Drainage network invert and pit documentation
Port berth and wharf structure as-built
Retaining wall alignment and settlement monitoring baseline

FAQs: Civil & Infrastructure

Can you work to our survey control network?+
Yes. We use your existing control points or establish new marks tied to MGA94 or GDA2020 as specified. All deliverables are registered to the datum and projection in your scope so they drop into your 12d or Civil 3d project without manual shift.
Do you scan live traffic corridors?+
We plan captures around traffic management and rail possession windows. Terrestrial scanning from the shoulder or closed lane is common. For long corridors, drone LiDAR or photogrammetry reduces time on road and captures terrain context in one flight.
What accuracy can you achieve on corridors and structures?+
Terrestrial scanning of structures holds +/-2mm at typical ranges, while aerial LiDAR over open corridors achieves +/-30mm vertical at standard flying heights. We place independent check points and report the achieved accuracy against them, so the numbers are defensible for design verification, load-rating inputs, and progress claims.
Can you map underground services with the survey?+
Where locatable utilities are in scope, we record and label services and can report to the quality levels described in AS 5488 for subsurface utility information. Visible pit and drainage geometry, including invert levels, is captured directly in the scan. For non-visible services we coordinate with a utility locator and integrate their findings into the deliverable.
