From site survey to digital twin — the geospatial backbone for construction
Contractors, engineers, and asset owners build on a single georeferenced model: survey, reality capture, BIM integration, and progress monitoring that keep design, field, and handover honest from groundbreaking to operations.
The project lifecycle on a single spatial model
One georeferenced source of truth across survey, design, construction, and handover — built for infrastructure, buildings, and heavy civil projects alike.
Site Survey & Terrain Modelling
Topographic surveys, digital elevation models, and existing-conditions models from survey-grade GNSS, LiDAR, and photogrammetry — georeferenced and ready for design.
Reality Capture & Point Clouds
Register terrestrial, mobile, and drone scans into a unified, georeferenced point cloud for design coordination and as-built verification.
BIM–GIS Integration
Bind IFC building models to their real-world site context, cadastre, and underground utilities so design and ground truth live in one environment.
Progress Monitoring
Compare periodic imagery, drone flights, and scans against the design model to track as-built progress objectively, period over period.
Cut-Fill & Earthworks
Volumetric and balance analysis from before-and-after surfaces to plan, verify, and reconcile earthmoving against the design surface.
4D Construction Sequencing
Link the schedule to the model so teams visualise the build sequence, staging, and clash windows across time — not just in plan.
Drone & Aerial Survey
Orthomosaics, digital surface models, and 3D meshes from UAV flights, processed into analysis-ready deliverables for every stakeholder.
Clash & Encroachment Detection
Detect design conflicts and boundary, setback, and easement encroachments against survey and cadastral layers before they reach the field.
Reality capture to analysis-ready deliverables
Airfree runs the full pipeline from raw scans and flights to coordinated, measurable deliverables — no manual registration, no stranded point clouds, no data wrangling before your team can make a decision.
Digital twins platformLiDAR & Photogrammetry
Fuse laser-scan and image-derived point data into one measurement-grade record of the site at any phase of the build.
Georeferenced Point Clouds
Every scan is tied to real-world coordinates, so captures from different days, crews, and sensors align automatically.
Mesh & Surface Generation
Automated surface and mesh generation turns raw points into usable terrain, volumes, and 3D context for design teams.
Change & Progress Detection
Difference successive captures to quantify what moved, what was built, and what deviates from the design intent.
Built for contractors, engineers, and owners
Designed for teams accountable for programme, budget, and quality — one spatial model everyone trusts, not a folder of exports no one agrees on.
One Site Model, Every Discipline
Survey, design, and construction teams work from a single georeferenced model instead of emailing files and reconciling versions by hand.
Objective Progress Evidence
Imagery- and scan-derived progress gives owners, lenders, and auditors a dispute-resistant, time-stamped record of what was built and when.
Open Design Data
IFC, LandXML, GeoPackage, and point-cloud exports move cleanly between your design authoring tools and the spatial platform.
One connected platform, four product lines
AEC teams compose the platform to match the project — the same spatial engine, maps, cloud, and communication, working from one georeferenced model.
Every capability is available via REST and OGC-compliant APIs and is interoperable with the BIM authoring, project-controls, and GIS tools you already use — exchanged through open formats, not locked behind a proprietary hub.
- — IFC and BCF model and issue exchange
- — LandXML, GeoPackage, DWG, and E57 point-cloud export
- — OGC WMS / WFS / WMTS / 3D Tiles endpoints
- — REST API with OpenAPI 3.1 specification
- — Interoperable with common BIM and project-controls platforms
Design, build, operate — one continuous twin
The model you design with becomes the model you build against, and the twin you hand over — one spatial record that carries value across the whole asset lifecycle.
Design-Phase Context
Start design with an accurate, georeferenced model of the real site — terrain, boundaries, utilities, and constraints — not an assumption.
Build-Phase Verification
Verify the build against the model continuously, catching deviations and quantifying earthworks while they can still be corrected cheaply.
Operate-Phase Handover
Hand the owner a living as-built twin tied to the asset register, ready to carry into operations, maintenance, and future works.
