Civil & Infrastructure

Civil and infrastructure scanning captures roads, bridges, rail corridors, drainage networks, and earthworks at a density traditional pick-up cannot match. We combine the Trimble X7 and Trimble X9 for structures and confined geometry with DJI Matrice 4T aerial LiDAR for corridors and open terrain. The result is a single georeferenced dataset that supports design, condition assessment, volume measurement, and as-built records without sending a survey crew back to site each time a new question comes up.

Engineers need geometry that matches field conditions. Bridge soffits, culvert invert levels, retaining wall alignments, and road cross-falls all drive design and assessment decisions, and all of them are slow and risky to measure by hand on live infrastructure. Laser scanning records millions of points in hours, so the consultant works from a complete surface rather than a sparse set of string-line shots. For corridor projects, drone LiDAR captures the road, batters, drainage, and adjacent terrain in one flight, keeping crews off the carriageway.

Deliverables are produced for the platforms civil teams actually use. We export classified point clouds in LAS and LAZ, triangulated surfaces and digital terrain models in LandXML for 12d and Civil 3D, cross-sections and long-sections in DWG, and volume reports for cut, fill, and stockpiles. Where utilities are part of the scope, locatable services are recorded and labelled to support subsurface utility information workflows. Ortho-mosaic imagery provides a visual basemap that sits underneath the design.

Accuracy is verified, not assumed. Aerial LiDAR achieves +/-30mm vertical in open terrain at standard flying heights, while terrestrial scanning of structures holds +/-2mm at typical ranges. Independent check points placed across the site confirm the achieved accuracy before delivery, and a survey report documents the control, datum, and residuals. This evidence base matters for progress claims, design verification, and regulatory submissions where the numbers have to stand up to scrutiny.
