Solutions

Infrastructure

From live carriageways to completed roadworks — linear assets captured safely, verified against design, and handed over as data.

01The Work

As-built capture of completed roadworks

Scan the finished works — surface, kerbs, drainage, barriers, signage — before demobilisation, and certify what was delivered.

Roads & corridors

Kilometres of carriageway captured at walking or vehicle pace, with minimal traffic disruption.

Tunnels & underground

SLAM capture where GNSS is absent — clearance profiles, lining condition, services.

Structures & utilities

Bridges, culverts, gantries and utility corridors documented as measurable 3D records.

02The Approach

A road project is not finished when the surface is laid.

It is finished when the maintaining authority accepts a record of what was built. Traditionally that record is assembled from redlined drawings and spot measurements taken while traffic control is still in place—expensive to collect, incomplete by construction. As-built 3D capture closes that loop: the completed works are scanned in a single pass, referenced to the project datum, and compared directly against the design surface.

The result serves everyone downstream. The contractor demonstrates conformance and closes out the contract with evidence rather than assertion. The asset owner receives kerb lines, drainage inverts, barrier placements and clearances as measurable data, not paper. And the next project to touch that corridor begins from a record that reflects the ground—because it was measured from it.

Capture at walking pace matters most here: shorter lane occupancies, smaller traffic-management footprints, and the ability to re-scan a section in minutes when works are staged.

03The Workflow, Applied
01

Capture

Walk or drive the corridor with RTK-referenced LiDAR under minimal traffic control.

02

Process

Georeferenced, colourised cloud aligned to the project datum in LixelStudio.

03

Analyse

Design-surface comparison, clearance checks, drainage and kerb geometry extraction.

04

Deliver

Certified as-built record, conformance report and asset data for handover.
