Dock-Based Infrastructure Inspection & Monitoring

Traditional bridge inspection requires scaffolding, under-bridge inspection units, or rope access — all of which involve significant traffic management and cost. Dock-based drone inspection captures equivalent visual data from multiple angles without any physical access infrastructure. While it does not replace hands-on tactile inspection for all assessment types, it dramatically reduces the frequency and scope of access-intensive inspections required.

Yes. The Matrice 4TD’s radiometric thermal sensor detects temperature differentials caused by subsurface delamination, voids, and moisture ingress in concrete structures. Best results are achieved during thermal transition periods (early morning or late afternoon) when temperature gradients between sound and deteriorated concrete are most pronounced.

THE FUTURE 3D conducts full airspace assessment as part of the SORA process for every dock deployment. Where sites fall within controlled airspace, restricted zones, or proximity to aerodromes, we coordinate with the relevant air navigation service provider and national aviation authority to obtain specific operational authorisation.

Dock-based drones are optimised for top-down and oblique capture. For detailed underside inspection of bridge decks, pier columns, and bearing seats, we complement dock operations with manually piloted close-range flights using specialised obstacle-avoidance platforms. The dock system provides ongoing top-surface monitoring while periodic manual flights address underside elements.

Visual imagery is delivered in high-resolution JPEG and DNG formats with full EXIF geolocation data. Thermal data is provided in radiometric RJPEG format compatible with FLIR Tools, DJI Thermal Analysis, and other thermography software. Orthomosaics are delivered in GeoTIFF format. 3D models are available in OBJ, LAS, and E57 formats compatible with standard asset management and BIM platforms.

For infrastructure networks spanning hundreds of kilometres — such as motorway corridors or railway lines — multiple dock systems are deployed at strategic intervals. All docks are managed centrally through DJI FlightHub 2, enabling coordinated mission scheduling and unified data management across the entire asset portfolio.

Yes. The resolution and accuracy of dock-captured imagery meets the requirements for condition rating assessments used by European infrastructure managers. Data can be integrated into asset management systems and formatted to comply with national reporting standards such as the UK’s DMRB bridge inspection regime or Germany’s DIN 1076 assessment protocol.

The DJI Dock 2 can be deployed and operational within a few hours by a single person due to its 34 kg weight and portable design. For pre-positioned docks at known vulnerable assets (e.g., flood-prone bridges), automated post-event missions can be triggered remotely within minutes of an event alert.

At a flight altitude of 30 metres, the Matrice 4D delivers a ground sample distance (GSD) of approximately 0.7 cm/pixel, sufficient to identify cracks as narrow as 2–3 mm. Lower flight altitudes produce finer resolution for detailed defect characterisation.

Yes. THE FUTURE 3D delivers data in open, industry-standard formats that integrate with asset management platforms including Bentley AssetWise, Confirm, and Bricsys. We can also configure automated data delivery pipelines to push processed imagery and reports directly into your existing workflows.
