Drone Survey & Inspection Measured Building Survey Topographical Survey LiDAR Survey Photogrammetry CAD & Revit / BIMInfrastructure surveys,
without closures, ropes or possessions.
The hardest part of surveying infrastructure is usually getting to it. Norelo captures bridges, structures, corridors and plant with drones, LiDAR and photogrammetry, close-up condition data, survey-grade geometry and repeatable monitoring, while the asset stays live and the traffic keeps moving.
The asset never wants to be inspected
Infrastructure data has always been bought with disruption: lane closures for the underbridge unit, possessions for the rail survey, rope teams on the dam face, and programme risk everywhere. The result is that assets get inspected as rarely as owners can justify, and known unknowns accumulate between visits.
Norelo inverts the economics. CAA-authorised drones put close-up 4K eyes on decks, soffits, bearings and parapets while traffic runs; aerial LiDAR maps corridors at up to 200 hectares a day; and terrestrial scanning records structures and plant to the millimetre. More data, more often, with nobody stood anywhere dangerous.
Capture across the asset base
From a single culvert to a route-length programme, priced fixed and delivered to engineering formats.

Through the asset lifecycle
Inspection support. UK structures run on cyclical visual inspection regimes, and their weak point has always been access to the fabric. Drone capture gives the inspecting engineer complete, close-up, geolocated imagery of every face, soffit and bearing shelf, gathered without closures, so the professional assessment is built on full coverage rather than what binoculars could reach. The judgement stays with the engineer; the evidence gets dramatically better.
Design on existing assets. Widening, strengthening, re-decking and utilities diversions all start from geometry, and record drawings lie. A registered point cloud of the structure and corridor gives designers reality: true clearances, true levels, true alignment, and clash-free interfaces the first time.
Construction verification. Scans during and after works confirm what was built against what was designed, pre-pour checks, as-built records and handover data that the maintaining authority can actually use.
Monitoring & trending. Where movement is suspected, a scan baseline turns concern into measurement: repeat captures are compared in millimetres, mapped as deviation surfaces and trended across visits. Earthworks, retaining structures, historic masonry arches and settlement-prone approaches all benefit from evidence that accumulates.
Asset knowledge & digital twins. Owners increasingly want a living geometric record of their estate. Point clouds, models and imagery, captured consistently and archived openly, become the geometric backbone of the asset management system: every future question starts from data already on the shelf.
The programme case is simple arithmetic: capture without closures costs less than the traffic management alone on a conventional survey, removes the working-at-height risk entirely, and because our archive keeps every dataset, repeat visits price as capture only, the mobilisation maths keeps improving as the programme runs.
Why asset teams programme us in
Safety by design
Nobody at height, on track or over water, the survey disappears from your risk register, and RAMS arrive before we do.
Engineering-grade data
Control networks, checkpoints and verified registration, geometry your designers can build on and your checkers can audit.
Programme-friendly
No closures to book means capture happens when you need it, not when the traffic management window finally lands.
Formats engineers use
E57, LAS, DWG, Revit, IFC and GeoTIFF through one portal, straight into your design and asset systems.
The jobs we’re asked for most:
Good to know
Can drone capture replace our bridge inspections?
It supports them, it doesn’t replace them. Statutory and cyclical inspections remain the responsibility of the appointed engineer; our capture gives that engineer complete close-up imagery and measurable geometry of fabric that’s otherwise expensive or dangerous to reach. Better evidence, same accountability.
Do you need road closures or possessions?
Usually not, that’s the point. Drone capture works over live carriageways and adjacent to operational infrastructure under our CAA authorisation, with stakeholder permissions handled in planning. Where specific operator rules apply, rail especially, we plan capture around them and say so up front.
How accurate is the data for engineering design?
Survey-grade: GNSS and total station control networks, RTK-positioned aerial capture, and verification against independent checkpoints, with accuracy statements issued alongside the data. Clearances, levels and alignment come from measurement, not estimation.
Can you monitor a structure for movement over time?
Yes. A baseline scan fixes the geometry; repeat captures on an agreed cycle are compared in millimetres and presented as deviation maps and trends. It suits settlement watches, leaning masonry, earthworks and post-works confirmation monitoring.
What do engineers actually receive?
Whatever your workflow expects: registered point clouds in E57/RCP/LAS, CAD sections and drawings in DWG, Revit or IFC models where BIM applies, GeoTIFF orthos and surfaces, plus geolocated inspection imagery, all through one secure portal with the archive retained.
Can you capture plant rooms and confined structures?
Yes. The RTC360 scans tight, dark, GPS-denied spaces in dense detail, plant rooms, culverts, substations and process facilities, planned around shutdown and access windows, feeding retrofit design and asset models.
Can you handle route-length programmes?
Yes, they’re where the economics shine. Aerial LiDAR covers up to 200 hectares a day, multi-structure inspection rounds are batched into efficient mobilisations, and portfolio pricing reflects the volume. Tell us the route and the cycle and we’ll programme it.
