3D SCANNING AND DIGITAL TWINCapture reality with millimeter precision and turn it into live, data‑rich digital twins
We combine terrestrial laser scanning, mobile LiDAR and panoramic imaging to produce high‑fidelity point clouds and deliver Scan‑to‑BIM, as‑built CAD, and interactive digital twins—accessible on web viewers and integrated with GIS/BIM workflows.
What we deliver
Core deliverables
Registered Point Clouds (TLS & Mobile)
Millimeter‑accurate, noise‑filtered point clouds from terrestrial and SLAM/mobile scanning, aligned with survey control. Delivered in LAS/E57/RCP formats with QA/QC reports.
Scan‑to‑BIM & As‑Built CAD
Parametric BIM models (Revit/IFC) and as‑built CAD plans, sections and elevations. Level‑of‑Detail tailored to your scope (LOD 200–400) for design, permitting and fabrication.
Digital Twin & Visualization
Photorealistic Web‑based viewers and immersive experiences (mesh/point cloud), with asset metadata, annotations and optional IoT dashboards for live monitoring.
Additional Deliverables & Applications
Deformation & Monitoring
Tunnel convergence, settlement, and structural displacement analyses from repeated scans.
Reality vs. Model QA/QC
Clash detection and deviation heatmaps comparing BIM/CAD to the point cloud.
Asset Tagging & Panoramas
Georeferenced panoramas linked to assets, documents and tickets inside the twin.
