Drone Surveys & Photogrammetry
Every angle, on schedule, without scaffolding.
Every angle, without the scaffold.
Drone surveys deliver fast, repeatable aerial capture: site progress, orthomosaic mapping, photogrammetric models, aerial inspection, and volumetric stockpile measurement.
Flights are planned and flown by our own CAA-registered operator within the UK drone rules for the flight, including airspace permissions, site access, weather conditions and the standard 120m altitude limit unless specifically authorised. Flights follow a planned grid with calibrated control points on the ground. Imagery is processed into orthomosaics and 3D models. Inspections combine wide-area imagery with high-zoom detail captures of the items of interest.
Where it helps
- For monthly progress capture across a site
- To generate an orthomosaic for design or planning
- For roof, façade, or chimney inspection
- To measure stockpile or earthworks volume
- When working at height would otherwise need scaffolding
- For visual records before, during, and after a project
What you receive
- Geo-referenced orthomosaic
- 3D photogrammetric model
- Stockpile volumetrics report
- Inspection report with annotated still imagery
- Time-stamped progress imagery and short flythrough videos
A note on interpretation. Drone flights are made within the UK drone rules for the flight. The output is a visual and photogrammetric record; it is not an intrusive or contact structural inspection.

Common questions.
Do you have CAA authorisation?
We fly our own drones as a CAA-registered operator, and our pilots hold Flyer IDs. We fly in the Open category, so we plan each site against those rules and tell you at the quote if a location needs more.
What can drone surveys be used for?
Progress monitoring, photogrammetric surveys, orthomosaics, volumetric calculations, façade inspection, and aerial photography for planning and marketing purposes.
When do I need to pay?
All surveys are invoiced by proforma. Full payment is required before we mobilise. We'll send the proforma invoice immediately on confirmation and works are scheduled once cleared funds are received.
Do your operatives have CSCS cards?
Yes. All Corvus operatives hold valid CSCS cards and carry full public liability insurance. We can provide method statements and RAMS on request.
What areas do you cover?
We cover the whole of the UK. Travel costs for sites outside London may apply, we'll confirm this when quoting.
Can you work in occupied buildings?
Yes. GPR and Ferroscan equipment is non-intrusive and silent. We regularly work in occupied offices, hospitals, and schools with minimal disruption.
Need eyes over the whole site?
Send drawings, photos or proposed fixing locations and we'll advise the right survey approach.
