Our Process
How we work
Scope & Survey Control
We establish survey control and coordinate datum before capture. Traffic management or rail protection is arranged if required.
Data Capture
Terrestrial scanners and UAV-mounted LiDAR capture the full corridor or structure. We combine ground and aerial data for complete coverage.
Processing & Analysis
Point clouds are classified, filtered, and georeferenced. We generate surface models, cross-sections, and volume calculations from the processed data.
Delivery & Reporting
All deliverables are supplied in your preferred formats with a detailed survey report. We can present directly to your engineering team if needed.
FAQs
Common questions
Can you scan active road corridors?
Yes. We work on active roads regularly and hold current traffic management qualifications. For high-speed roads, we can deploy mobile LiDAR or UAV scanning to minimise lane closures. Lower-speed urban roads are typically scanned with terrestrial LiDAR under rolling traffic control. We coordinate with your traffic management provider or can arrange our own accredited crew depending on the jurisdiction.
How accurate are UAV LiDAR surveys for earthworks volumes?
Our DJI L2 LiDAR payload achieves vertical accuracy of +/-30mm in open terrain at standard flying heights (60-80m AGL). For stockpile and earthworks volume calculations, this translates to volumetric accuracy within 1-2% for typical civil sites. We always place ground control points and check shots to verify accuracy before delivering results. The accuracy is suitable for progress claims, design verification, and regulatory reporting.
What formats do civil engineers typically need?
Most civil engineers work in 12d, Civil 3D, or similar platforms. We commonly deliver georeferenced LAS/LAZ point clouds, TIN surface models in LandXML format, and cross-sections in DWG. For GIS workflows, we can provide GeoTIFF ortho-mosaics and shapefiles. We are flexible and can produce any standard geospatial format your team requires.
