Drone infrastructure inspection across the UK

Bridges

External surfaces, decks where visible, piers, abutments, structural elements and difficult to view areas where the proposed operation allows safe capture.

Telecom towers and masts

External components, antennas, mounts, cabling and visible structural condition where suitable equipment and operating conditions allow.

Utilities infrastructure

External utility assets, supporting structures and associated infrastructure according to the agreed scope.

Industrial structures

Chimneys, stacks, tanks, silos, gantries, industrial roofs and external plant.

Energy infrastructure

Selected renewable and energy assets where appropriate pilot capability, sensors and permissions are available.

Transport infrastructure

External infrastructure associated with roads, rail, ports and other transport environments where site access and operational permissions can be agreed.

Not every type of infrastructure assignment can automatically be undertaken. Some environments require specialist competency, specific aircraft, particular sensors, Operational Authorisation, site owner permission, airspace permission, additional method statements, specialist induction or coordination with infrastructure operators. These requirements are assessed for each assignment before a pilot is matched.

Drone capture can record high resolution visual evidence of accessible external bridge elements without requiring personnel to access every area solely for photography. What can be reached depends heavily on the structure, its surroundings and the permitted operation, so underside and close proximity capture is assessed case by case rather than assumed.

Depending on the agreed brief and safe operating conditions, capture may include:

• Decks and parapets where visible
• Piers and abutments
• External steelwork, masonry and concrete surfaces
• Bearings where safely visible
• Staining, corrosion indicators and cracking visible in imagery
• Vegetation or obstruction affecting the asset
• General external condition

Drone imagery is inspection data. Structural interpretation, engineering assessment and certification remain the responsibility of appropriately qualified professionals.

Aerial capture may support visual inspection of tower structures, antennas, mounts, dishes, external cabling, fixings, corrosion indicators, visible damage and general asset condition.

Telecom environments can present specialist operational considerations, including electromagnetic interference, proximity to structures, asset height, the surrounding environment, airspace and safe stand off distances. For that reason these assignments are capability matched to pilots with relevant experience, equipment and permissions. Not every pilot in the network is suitable for tower work.

Aerial data capture may suit power infrastructure, utility structures, renewable assets, energy sites, pipelines where externally visible and associated industrial infrastructure, according to the agreed scope.

Electricity infrastructure requires particular care. Drone Assisted does not automatically undertake close proximity high voltage inspection. Scope, equipment, permissions and operating requirements are assessed with the asset owner before an assignment is accepted. For overhead lines, pylons and electricity networks specifically, see drone power line inspection.

Where temperature differences are relevant to the brief, see thermal drone surveys, and for module level fault indication across arrays see solar panel drone inspection.

Industrial assignments commonly cover chimneys, stacks, tanks, silos, gantries, warehouses, industrial roofs, external plant and other high level structures.

Drone inspection is most useful where the primary requirement is gathering visual evidence from difficult to view external areas. It does not replace non destructive testing, physical testing, intrusive inspection, engineering inspection or specialist certification, all of which require physical access and qualified professionals.

Deliverables are agreed before the assignment. Depending on that brief, outputs may include:

• High resolution imagery. Detailed photographs of agreed asset surfaces and components.
• Video. Overview, orbit or targeted video where appropriate.
• Annotated imagery. Images identifying locations or observations where this has been agreed as part of the scope.
• Thermal imagery. Where suitable sensors, conditions and specialist capability are required and available.
• Organised evidence packs. Images and files organised by agreed asset areas, elevations, components or client requirements.
• Repeat capture. Repeat imagery to support visual comparison over time where comparable capture is operationally practical.
• Original files. Original imagery or data where requested as part of the assignment.

A formal engineering inspection report is only provided where the assignment specifically includes an appropriately qualified specialist.

The Drone Assisted and pilot role

Capturing aerial imagery or data according to an agreed brief, delivered in the agreed format.

The specialist professional role

Engineering interpretation, structural assessment, non destructive testing interpretation, certification or professional sign off where required.

Drone capture provides engineers, inspectors, asset managers and other specialists with better visual evidence. It does not replace professional engineering judgement or statutory inspection requirements.

Infrastructure operators, utilities and service companies managing assets across different regions can use one managed network instead of independently sourcing a local drone pilot for every location. Coverage spans England, Scotland, Wales and Northern Ireland.

Drone Assisted can work from a consistent assignment specification across a portfolio while matching local pilot capability to each site, so outputs stay comparable between regions and procurement stays with a single point of contact. Availability at any individual site is confirmed according to location, asset type and specialist requirements.

Assignments can be structured as:

• One off inspection capture
• Scheduled asset monitoring
• Annual or periodic inspection support
• Post event inspection
• Maintenance planning imagery
• Before and after capture
• Portfolio inspection programmes

Repeat viewpoints and capture can be planned where operationally practical. Exact repeat flight paths cannot be guaranteed, because weather, site activity, temporary works, airspace and safety requirements affect how an asset is flown on the day.

Aerial capture can provide timely visual evidence following storm damage, accidental damage, suspected external deterioration, maintenance issues, impact damage or other asset incidents, before deciding whether physical access or specialist investigation is required.

The same evidence can support insurers, loss adjusters and asset managers reviewing a claim or a maintenance decision. Imagery records visible external condition at the time of capture; it does not determine liability or cause, which remain matters for appropriately qualified professionals. See also drone surveys for insurance claims.

Complex infrastructure assignments can involve factors such as controlled airspace, nearby roads or railways, members of the public, critical infrastructure security, RF or electromagnetic environments, high structures, restricted sites, site inductions, client RAMS requirements, specialist PPE, permissions from asset owners, particular aircraft or sensors, and Operational Authorisation where required.

Not every assignment involves all of these. Requirements are assessed per job, and the outcome of that assessment determines which pilot, aircraft and permissions are needed. See commercial drone pilot requirements for more detail on how pilots are checked.

Drone infrastructure inspection suits large, specialist, industrial, utility, transport and infrastructure assets, where competency, permissions and equipment matching matter as much as the capture itself.

General drone inspection suits wider property, roof, building and commercial inspection requirements. For those, see our drone inspection services.
