We depend on well-maintained infrastructure to support our daily lives, including our energy systems, transportation networks, telecommunications services, and drinking water supplies. Inspecting infrastructure assets—whether bridges, power lines, roads, buildings, or natural areas and managed landscapes—can be costly, time-consuming, and risky when relying solely on traditional inspection methods. How can organizations or government agencies leverage technology to efficiently and safely assess these types of assets?

Recently, many industries have embraced unmanned aerial systems as a scalable solution for remote inspections. The approximate value for drone services in the energy sector alone may crest to $178 million by 2030, and the demand is sharply rising in other markets as well. This advanced technology captures more information at a faster rate, allowing organizations to identify critical maintenance needs while minimizing the time and risk associated with manual inspections. Additionally, the high-resolution data gathered by drones can be used for further analysis, including 3D modeling, predictive analysis, and change detection. While some barriers to adoption remain, they are expected to diminish as technology advances and usage becomes more widespread.

Applications for Drones

• Transportation. In addition to delivery services, traffic monitoring and public transit security, drones are ideal for inspecting infrastructure, including bridges, railways, and highways, capturing visuals and identifying problems while improving safety for inspectors.
• Utilities. In an emergency response, drones are especially useful at assessing damage quickly. They can also monitor and inspect transmission lines, power stations, and substations, detecting faults well before failures occur.
• Environmental. Drones can collect air and water quality data, assess agricultural lands, detect pollution, and aid in conservation efforts by detecting animal / invasive plant species.

Ongoing Challenges 

The full potential of aerial inspection technology has yet to be realized. These systems are still subject to airspace regulations and require special permissions for commercial flights. Environmental and weather challenges, along with obstacles like confined spaces, trees, power lines, and other structures, can hinder operations. Additional limitations include the significant storage and processing power needed for data management, battery life constraints, and potential signal interference. Despite these challenges, the efficiency and safety benefits continue to drive widespread use across various industries.

Benefits of Drone Inspections

• Safety. Drones can inspect hazardous environments, confined spaces, and tall structures without putting anyone at risk. In an emergency situation where information is needed immediately, such as a wildfire or partially collapsed building, drones can be deployed. keeping everyone out of harm’s way.
• Efficiency. Drones can quickly scan large areas using pre-programmed routes, and inspect infrastructure, like bridges, without shutting down access.
• Lower costs. Without paying for large inspection crews, scaffolding, cranes, or other large equipment, the typical high costs associated with inspections are reduced.
• Advanced analytics. Equipped with high-resolution cameras, thermal imaging, LiDAR, and AI integration, drones can capture detailed images, detect issues that are otherwise invisible to the human eye, and analyze patterns more accurately than manual inspections.
