If you're designing from 2D plans, you're designing blind.

BIM managers, civil engineers, and design teams routinely discover that existing CAD is wrong, missing, or decades out of date. A dense drone point cloud gives your designers the actual as-existing state of the world.

Terrestrial Scanning Is Slow

Tripod-based laser scanning an open site can take days of moving the instrument, setting control, and registering scans. A drone photogrammetry or LiDAR flight captures the same ground in a couple of hours with comparable density.

As-Built vs Designed Drift

Contractors rarely build exactly what the design said. Without a verified as-built point cloud at handover, commissioning teams inherit unknown deviations, and clash detection on future alterations becomes guesswork.

Live-Site Scanning Risk

Putting surveyors in a live construction, rail, or industrial environment to operate tripod scanners is a persistent safety exposure. A drone removes humans from the hazard zone while delivering a richer dataset.

Any drone can capture a cloud. Few drone pilots can deliver one an engineer will accept.

I have reviewed too many point clouds delivered as a single unclassified mess of 200 million points with no ground class, no control, and no co-registration. That dataset is unusable in a BIM or civils workflow.

Every point-cloud drone operator on this network flies with ground control, processes in Pix4D or Agisoft Metashape (or directly from a LiDAR payload), classifies returns into ground, vegetation, buildings, and noise, and ties the output to OSGB36 or your project coordinate system.

That means your designer opens the file in Revit, Civil 3D, or Navisworks and gets straight to modelling — not cleaning the data.

Engineering-Grade Output

Classified & Project-Coordinated

Point cloud outputs your BIM and civils teams can use on day one.

Our network operators deliver data in industry-standard formats ready for Revit, Civil 3D, Navisworks, and Bentley workflows.

LAS / LAZ Point Clouds

Dense point clouds at 200–2,000 points per square metre, delivered in the open LAS or compressed LAZ format. Every point carries XYZ, RGB colour, intensity, and return number.

Classified Returns

Points classified into ground, low / mid / high vegetation, buildings, and noise per ASPRS standard. Ready for surface modelling, bare-earth DTM generation, or clash detection straight out of the box.

CAD-Importable Formats

Also delivered as RCP/RCS for Autodesk, POD for Bentley, and E57 for cross-platform sharing. Plus matching DTM mesh (OBJ/FBX) and contour DXF for teams that prefer vector surfaces.

Book your point cloud capture in 3 steps.

We connect you with the specific BIM and engineering-grade specialists you need, instantly.

Describe the Capture

Tell us the site address, area or linear length, density required (points per m²), and the design package the cloud will feed into — Revit, Civil 3D, Navisworks, Bentley.

Compare Specialists

We route your brief to drone pilots with photogrammetry and LiDAR platforms. You receive quotes with density specs, classification schemes, and coordinate system options.

Capture & Deliver

Your drone pilot flies the mission, processes and classifies the cloud, and delivers LAS/LAZ plus CAD-specific formats via secure cloud link with a registration report.

"The LAS cloud dropped straight into our federated Revit model with correct classification. Our modellers shaved two weeks off the existing-conditions stage compared with the previous tripod scan approach."

Ibrahim Qureshi

BIM Manager, Birmingham

"We use recurring drone point clouds for monthly stockpile volumetrics on an aggregate site. The density and classification are so consistent we reconcile against our weighbridge data to within 2 percent."

Lucy Thornbury

Quarry Manager, Peterborough

"For an as-built verification on a highways widening, the drone point cloud found six divergences from the design that the contractor had not flagged. Saved our client a very expensive dispute during commissioning."

Point Cloud Mapping FAQ

Technical questions on density, classification, and BIM integration.

Photogrammetry or LiDAR — which do I need?

Photogrammetry is cheaper, faster, and delivers a beautifully coloured point cloud — ideal for open sites, stockpiles, and as-built modelling. LiDAR penetrates vegetation and works in low light, so it wins for wooded sites, corridor surveys, and anywhere bare-earth DTM fidelity matters most. Most drone operators on this network can quote for either payload.

What point density can I expect?

Photogrammetry clouds typically land at 400–2,000 points per square metre depending on flight altitude and overlap. LiDAR ranges from 200–800 points per square metre at standard flight speeds, rising for slower sorties. Tell us the density your workflow needs and we will match the right platform.

Can I register the cloud to my project coordinate system?

Yes. Drone operators tie capture to surveyed ground control points and register the output to OSGB36, OSTN15, site-local grids, or any project coordinate system you specify. A registration report with residuals is delivered alongside the data so your quality team has full traceability.

Does the cloud work inside Revit and Navisworks?

Yes. Drone operators supply matching RCP/RCS (Autodesk ReCap) files ready to attach into Revit, AutoCAD, Civil 3D, and Navisworks, and POD for Bentley Descartes/OpenRoads users. E57 and PLY are available for teams using Leica Cyclone, FARO Scene, or open-source tooling.
