Drone Surveys for Critical Infrastructure
Safe, Efficient, and Accurate Data Capture for Complex Environments
When it comes to maintaining and monitoring the UK’s most valuable assets, drone surveys for critical infrastructure offer a faster, safer, and more cost-effective alternative to traditional inspection and survey methods.
At DJM Aerial Solutions, we deliver high-resolution drone data that helps asset owners, contractors, and public sector organisations inspect, monitor, and maintain everything from rail lines and bridges to high-rise buildings and subterranean culverts — all without the need for expensive scaffolding, closures, or manual entry into hazardous environments.
What Is Considered Critical Infrastructure?
Critical infrastructure refers to the essential assets and systems that support the health, safety, mobility, and economy of the country. This includes:
Bridges and overpasses
Rail lines and embankments
Underground culverts and drainage systems
High-level buildings and structures
Utilities and energy distribution networks
Road corridors and transport hubs
These assets must be inspected regularly to ensure structural integrity, operational safety, and compliance with regulatory standards.
The Role of Drone Surveys
Traditional inspections can require road closures, rail possession, rope access teams, or confined space entry permits. A drone survey removes many of these barriers by enabling remote visual and spatial data capture from a safe distance — often without interrupting operations.
We use both external aerial drones (such as the Matrice 300 and Mavic 3 Enterprise) and confined space drones (like the Elios 3) to access and survey all aspects of infrastructure, both above and below ground.
Assets We Survey
1. Bridges and Overpasses
Visual inspection of bearings, joints, soffits, and decks
Thermal detection of moisture ingress or delamination
Orthomosaic mapping for structural monitoring
Ideal for over water, motorway, or inaccessible spans
2. Rail Infrastructure
Embankment stability and vegetation analysis
Trackside structural condition
Culvert and drainage assessment
Survey-grade mapping of lineside features
3. Subterranean Culverts and Drainage Systems
Confined space surveys using Elios 3
Condition assessment without manual entry
Perfect for debris-blocked or unsafe systems
Mapping for subsidence, development, or piling impact
4. High-Level Structures
Rooftop inspections
Façade surveys and cladding condition
Gutter, parapet, and rooflight assessments
Ideal for heritage buildings, public infrastructure, and towers
Benefits of Drone Surveys for Critical Infrastructure
No human entry into hazardous or confined spaces
Reduced or eliminated need for access platforms, scaffolding, or rope teams
Rapid deployment and minimal disruption to operations
Detailed reporting using 4K video, high-resolution images, and thermal overlays
Accurate georeferenced outputs for mapping and CAD integration
Ideal for emergency response, post-event inspections, or condition monitoring
Supports long-term asset management and maintenance planning
Full compliance with CAA regulations and safety protocols
Data Outputs
Every project can include:
Visual imagery
Thermal imagery
Orthomosaic mapping
Elevation models
LiDAR point clouds
3D models for BIM
Visual defect tagging
Detailed inspection reports
All data is captured and processed to meet engineering and compliance standards, ensuring it is ready for immediate use by asset owners and consultants.

We work with local authorities, infrastructure contractors, engineers, and maintenance teams to deliver survey data that is safe, compliant, and cost-effective.
Frequently Asked Questions About Drone Surveys
A drone survey is a remote data collection method used to inspect or map essential infrastructure such as bridges, rail lines, and drainage systems without manual access.
We survey bridges, overpasses, rail networks, culverts, high-rise buildings, rooftops, road corridors, and other complex or high-risk environments.
Yes. We use drones that comply with UK CAA safety regulations and follow strict risk assessment protocols to operate safely near critical infrastructure.
Yes. We use the Elios 3 drone for confined space surveys such as culverts, internal chambers, ducts, and drainage systems that are unsafe for human entry.
We collect visual, thermal, topographic, and spatial data. This includes photos, videos, orthomosaics, LiDAR point clouds, and 3D models.
No. In most cases, we can fly without requiring closures or shutdowns, significantly reducing downtime and access costs.
Yes. Using RTK drones and survey-grade workflows, we provide centimetre-level accuracy suitable for planning, design, and maintenance work.
Yes. We use drones with radiometric thermal sensors to detect heat loss, water ingress, and overheating components in critical infrastructure.
We work with local councils, engineering consultants, Tier 1 contractors, infrastructure managers, and asset owners across the UK.
We operate nationwide from our base in the North East of England, deploying quickly to support both planned and emergency survey work.
