Initial survey
Capture of the current state before designing, altering, partially demolishing or intervening.

Construction progress monitoring and reality capture, so you build on real data.
We monitor construction progress with laser scanning, SLAM and drones: we capture each stage, compare it with the previous one and with the BIM model, and publish it in VisionHub. We supply LIDAR, photogrammetry, point clouds, as-built BIM and web visualisation to control works, record states, reduce uncertainty and coordinate teams against captured reality — useful in particular when part of the project team is not on site or works from another country. Based in Madrid, working across Europe.
Control what exists, what is being built and what is handed over.
Captured data lets decisions be taken before problems reach site, states be evidenced, and final documentation be more trustworthy.
Progress monitoring
Visual and metric comparison of progress, phases, clashes and completed areas. How we do it.
As-built handover
Point cloud, drawings, BIM model and visualisation of the final asset for operation or maintenance.
Construction site monitoring with measurable data.
A photo tells you how the works are going; a point cloud tells you how much, where and by how far they deviate. We capture the site by milestone, compare each state with the previous one and with the design, and keep everything in one place so the contract administrator, the contractor and the client can check it without travelling.
Periodic scans and drone flights by milestone
Terrestrial laser scanning (TLS) where accuracy matters, SLAM to walk whole floors quickly and drone flights for the plot, roofs and façades. Each capture is tied to a works stage and georeferenced in the same system as the previous ones.
Stage-by-stage and BIM comparison
One cloud against the previous one shows what has changed; against the design model, where the built work departs from the design. Cloud-to-mesh comparison (C2M) produces a colour map of deviations, explained in our CloudCompare guide. The same data feeds the final as-built BIM.
Quantities and volumes
Earthworks, excavation, fill and stockpiles measured on the point cloud or the digital terrain model between two dates. They let payment valuations and site measurements be checked against data any party can verify again.
Services before they are closed in
We scan building services before ceilings and partitions are closed. The route of every duct, tray and pipe is recorded and can be measured later without opening anything up: useful for maintenance, alterations and claims.
Everything published in VisionHub
Each capture is published in VisionHub, which also brings live cameras, timelapse, compared photos and 360 tours. It opens in the browser, you measure on the cloud and overlay the BIM model. We compare it with other viewers in our BIM viewers guide.
Open formats
The point cloud is always delivered in open formats (E57, LAS or LAZ), so it does not depend on any one piece of software. Everything else (orthophotos, deviation reports, drawings or BIM model) as agreed in the brief.
Architecture, engineering, contractor and client.
The same capture can serve several roles if the deliverable is planned: design office, site manager, contract administrator, client, maintenance or facility management.
During design and works
- A reliable base for alteration or refurbishment design.
- Validation of existing geometry and available space.
- Clash control and complex setting-out.
- Visual monitoring by drone or 3D capture.
At handover
- As-built BIM model to the agreed scope.
- Final-state point cloud.
- Derived drawings and technical documentation.
- Web viewer for later reference.

We combine capture and modelling techniques by works stage, accuracy and the deliverables your team needs.
Questions about construction.
Why scan before designing a refurbishment?
So the design sits on real geometry rather than on old or missing drawings. The scan records out-of-plumb walls, real levels, exposed services and available space — which is exactly where the surprises and cost overruns of a refurbishment concentrate.
How is what has been built compared against the design?
By overlaying the point cloud of the works on the design model to measure real deviations, stage by stage. It exposes clashes and setting-out errors while they can still be corrected, instead of at handover.
How much does scanning disrupt the works?
Little: capturing a floor or a work face is usually resolved in a day or less, without stopping work or clearing the area. Processing happens afterwards, off site.
What deliverable does the client or contract administrator usually ask for?
It depends who will use the data. The design office normally asks for drawings and an as-built BIM model; the client and facility management ask for the final-state point cloud and web viewer access to consult it during operation.
How often is a site scanned for construction progress monitoring?
It depends on the project and its milestones, not on a fixed calendar. Each capture is usually tied to a change of stage: end of earthworks, foundations, each structural floor, building services before ceilings and partitions are closed, and the final state. The drone can fly more often than the scanner, because capture is quicker. The frequency is agreed with the site management team when the monitoring is planned.
What is the difference between monitoring a site with photos or 360 tours and with laser scanning?
Photos and 360 tours show what the site looks like; a scan also measures it. The point cloud gives levels, thicknesses, out-of-plumb, volumes and deviations from the design, and lets you measure months later what has since been covered up. The two complement each other: in VisionHub, live cameras, timelapse, compared photos and 360 tours sit alongside the point cloud and the BIM model.
Can the works be compared against the BIM model?
Yes. The point cloud from each capture is aligned with the design BIM model (IFC or Revit) and the distance from every point to the model surface is calculated — the cloud-to-mesh or C2M comparison done, for example, in CloudCompare. The result is a colour map of deviations by area: as-built verification that lets execution be corrected in time and the model be updated up to the final as-built BIM.
