Capture
Measured reality
LIDAR, SLAM, drone and photogrammetry to document geometry, context, services and existing condition.
Service · Digital twin
Digital twins of buildings, industry and infrastructure.
A digital twin is a digital replica of an asset that already exists, true to its real condition and kept up to date. We deliver the complete twin of your building, plant or infrastructure: LiDAR and drone capture, a georeferenced point cloud, a BIM model and publication in the VisionHub web viewer, so design, maintenance and management teams can open it in a browser — which is exactly what a project team working remotely needs. We capture assets in Spain and across Europe.
A technical asset any team can open.
A digital twin is, simply, a faithful digital copy of something that already exists — a building, a plant, an item of infrastructure — that you can consult and measure from your desk instead of travelling to it. The value is not only in capturing the data but in making it usable: measure, review, compare, share and plan interventions without repeating the visit. For the full definition, with types, layers and examples, see our guide what is a digital twin.
Model
Structured data
Point cloud, as-built BIM, CAD, GIS, meshes or gaussian splats, according to how the asset will be used.
Viewer
Web access
Shared visualisation for clients, design offices, site teams, maintenance, heritage bodies or public authorities.
Managing with real data.
Digital twins earn their keep when an existing asset has to be maintained, altered, refurbished, extended, conserved or explained.
Infrastructure and industry
- 3D inventory of existing plant and equipment.
- Planning of maintenance, extensions or replacements.
- Remote checking of dimensions, routes and clashes.
- A base for integration with GIS, BIM or asset management systems.
Heritage and construction
- A record of the current state before any intervention.
- Support for refurbishment, restoration and historical documentation.
- Comparison between design, works and built reality.
- Visual walkthroughs for communicating with non-specialist stakeholders.
Digital twin of the Santillana Canal.
More than 12 km of drinking water conduits on the Santillana Canal, for Canal de Isabel II — the Madrid regional water utility — scanned inside and out and merged into one continuous point cloud as the basis of the digital twin. See the full case study.
The layer that turns data into decisions.
We publish the twin in VisionHub, a web viewer to navigate, measure, review areas, share views, toggle layers and reach the asset without installing specialist software on every workstation.
Point cloud
Review of captured geometry, basic measurements, sections and visual support for technical review.
BIM model
Exported IFC/RVT models brought in to coordinate the modelled asset against the captured reality.
Gaussian Splatting
Photorealistic representation when the space has to be explained through a natural visual experience.
From physical asset to digital twin.
A proven sequence that turns any existing asset into a digital environment the whole team can consult.
01
Scope of the twin
We define assets, uses and users: who will consult the twin and which decisions it has to support.
02
Data capture
Terrestrial LIDAR, SLAM or drone scanning, according to the asset, its setting and the accuracy required.
03
Processing and registration
We merge and clean the point cloud, georeferenced and complete, as the basis of the twin.
04
Building the twin
We integrate cloud, BIM models and technical documentation into one coherent digital environment.
05
Publication in the viewer
Web access to navigate, measure and consult the asset with no specialist software.
How the point cloud is validated.
A digital twin is only useful if its geometry can be checked. Before anything is built on the point cloud, we validate it at three levels and deliver the evidence with the data: you do not have to trust the model, you can verify it.
Registration
Documented closure error
Every scan station is brought into one reference system, and whatever does not fit between them is measured and delivered in a report, in millimetres.
Georeferencing
Official coordinates
The cloud is tied to the project's coordinate system with control points, so it lines up with mapping, cadastre and any later capture.
Model against cloud
Deviation map
Every BIM volume is compared with the points it was built from, and the difference is delivered as a deviation map: where the model departs from reality, and by how much.
A digital twin does not expire, it gets updated.
The difference between a one-off scan and a useful digital twin is what happens after the first delivery: who can open it, under what permissions, and how often reality is recaptured so the data does not drift out of date.
Access control
- Access per project or per user, with separate read and edit permissions.
- Shared links for clients, authorities or subcontractors with no account needed.
- Capture history, so the state of the asset can be compared across dates.
Updating the data
- One-off recapture after works, an extension or a significant incident.
- Periodic recapture on assets under continuous maintenance (industry, infrastructure).
- The twin is replaced or versioned: the traceability of the previous state is never lost.
Questions about digital twins.
Is a digital twin the same as a BIM model?
No. A BIM model describes the asset at one point in time, usually the design or the as-built state. A digital twin uses that model (or the point cloud) as its base, but it is kept up to date and connected to operational data: maintenance, inspections, sensors, cameras or documentation. The BIM model is one layer of the twin, not the twin itself.
What data does a digital twin include?
At a minimum, the real geometry of the asset as a georeferenced point cloud captured with LiDAR, SLAM or drone. On top of that come the BIM model of the elements to be managed, photographs, 360° walkthroughs, drawings and technical documentation. Where the use calls for it, maintenance records, inspections, sensors or site cameras are added as well.
How is a digital twin kept up to date?
With new captures of reality: after works, an extension or a significant incident, or periodically on assets under continuous maintenance. Each capture is published as a new version in the viewer, so the current state can be compared with earlier ones without losing traceability.
How is a digital twin of a building or infrastructure produced?
In five stages: define the scope (which asset, which uses, who will consult it), capture the data with terrestrial LIDAR, SLAM or drone as the asset demands, process and register the georeferenced point cloud, integrate cloud, BIM models and documentation into one coherent digital environment, and publish it in a web viewer that needs no specialist software.
Does anyone need to install software to use it?
No. We publish the digital twin in VisionHub, a web viewer that opens in the browser with no specialist software to install, shared per project and with permission control. That matters when the reviewing team sits in a different country from the asset.
What is a digital twin for?
It lets you measure, review, compare and plan interventions against real data, cutting down site visits and coordination errors in maintenance, refurbishment, extensions and asset management.
How is a digital twin's point cloud validated?
With three checks delivered alongside the data: the registration report documents the closure error between scan stations in millimetres; georeferencing to the project's official coordinate system, with control points, makes the cloud line up with mapping and later captures; and a deviation map compares every modelled element with the points it came from, so any discrepancy between model and reality is visible and measurable.
