Drone infrastructure inspection: what is drone inspection and why can it improve our lives

This method revolutionizes traditional inspection techniques by offering a safer, more efficient, and cost-effective approach. The primary aim of drone infrastructure inspection is to ensure the safety, integrity, and functionality of the inspected structures, often achieving this in a fraction of the time and cost associated with conventional methods. Drones provide access to hard-to-reach areas, capturing high-resolution images and precise data.

Risks reduction

This not only enhances the quality of inspections but also enables a more accurate evaluation of structural conditions, crucial for maintenance planning and intervention. Furthermore, drone infrastructure inspections significantly reduce the risk to human inspectors who often face hazards during manual inspections at heights or in dangerous areas. The integration of drone technology in infrastructure inspection is a progressive step towards safer, more resilient public and private infrastructure management.

How are infrastructure inspection drones used

The process of conducting drone infrastructure inspections is both systematic and meticulous, beginning with a detailed planning phase

Preliminary stages

Initially, the target area is defined, and environmental conditions such as weather and topography are assessed to ensure flight safety. Following this, the type of drone best suited to the inspection’s specific requirements is selected. For instance, fixed-wing drones are ideal for covering large areas, while multi-rotor drones are more suitable for detailed inspections of complex structures.

The inspection

During the inspection, drones are equipped with various sensors, including high-resolution, thermal, and multispectral cameras. These sensors capture visual and thermographic data, which are later analyzed to identify any anomalies or structural damages. Drones’ ability to fly at low altitudes and maneuver in tight spaces allows for the acquisition of superior quality images and data compared to traditional methods.

Legislative limits

Adherence to drone flight regulations is another crucial aspect of the process. These regulations often include height and distance limits, as well as the requirement for a certified operator to pilot the drone.

Detailed reporting

Once the drone infrastructure inspection is completed, the collected data are processed to produce detailed reports, providing valuable insights for infrastructure maintenance and management. This inspection process not only ensures greater efficiency and safety but also lays a solid foundation for informed decisions regarding the maintenance and potential refurbishment of the structures. The integration of drone technology in infrastructure inspection represents an advanced step towards more effective and proactive asset management.

Drone laws: what are the drone safe restrictions

In the European Union, the regulations for drone operations were updated with EU Regulation 2019/947

As of December 2020, registration of drone operators and certified drones became mandatory. Operations in the ‘specific’ category may be conducted after authorization by the National Aviation Authority. Drone users operating drones without class identification labels can continue to operate in the limited category under certain conditions. From January 2023, all operations in the ‘open’ category and all drone operators must fully comply with these regulations. Drone operators must register themselves with the National Aviation Authority of the EU country they reside in, and this registration is valid for a period defined by the authority.

In the United States, drone laws are regulated by the Federal Aviation Administration (FAA). For commercial drone operations, a commercial drone pilot license is required, and drones must be registered with the FAA. Drone Remote ID is also required for commercial drone operators, although full implementation has been delayed. While drone insurance is not required, it is recommended for commercial operations. For recreational drone pilots, drones weighing more than 0.55 pounds must be registered. All recreational flyers must pass an aeronautical knowledge and safety test (TRUST) and carry proof of passage.

Drones should be flown only for recreational purposes, within visual line of sight, and should not interfere with other aircraft. They must be flown at or below authorized altitudes in controlled airspace with prior FAA authorization, and at or below 400 feet in Class G (uncontrolled) airspace. For commercial drone services in the USA, those with drones under 55 pounds can operate under Part 107 guidelines. This includes flying at night, over people, and moving vehicles without a waiver, as long as certain requirements are met. Drone operators should avoid flying near airports as it is challenging for crewed aircraft to see and avoid a drone. Some operations under Part 107 rules may require a waiver.

Main applications of drones in building and infrastructure inspection

Drone infrastructure inspection revolutionize both civil and industrial sectors by enhancing efficiency and safety in monitoring operations:

Civil

SECTOR

In civil sector and urban environments, drone infrastructure inspection is employed for inspecting historical buildings, roofs, and coverings.

This allows for an assessment of structural conditions without the need for scaffolding or invasive equipment, reducing costs and risks for operators. Drones are also used for territory management, monitoring natural areas, and regions at risk of landslides or floods, providing valuable data for disaster prevention.

Industrial

SECTOR

Industries greatly benefit from drone infrastructure inspection, especially for inspections of industrial plants like refineries, power stations, and solar panels.

Drones enable quick and detailed inspection of infrastructure conditions, identifying areas needing maintenance. They are also used for inspecting power lines, reducing downtime and enhancing safety.

Specific Inspections

Drone Bridge And Railway Inspection

Drones provide precise visuals of bridges and viaducts, including hard-to-reach areas.

Drone Roof Inspection

Thermal sensors identify leaks or damages not visible to the naked eye.

Drone Industrial Warehouse Inspection

Aerial inspection helps assess structural integrity and identify potential issues.

Drone Photovoltaic Power Plants Inspection

Drones facilitate the analysis of solar panels, detecting malfunctions or damages.

Drone Power Line Inspection

These inspections help prevent service interruptions and ensure safety.

Focus on drone roof inspections: which features make drones ideal for roof inspections

Drone roof inspections are increasingly favored for their precision, speed, and safety. The key features making drones ideal for this task include high-resolution imaging and thermal sensing capabilities. These technologies enable drones to detect issues like structural weaknesses, water damage, and insulation flaws, often invisible to the naked eye. Drones can access difficult-to-reach areas, such as steep pitches and high roofs, without the need for risky manual inspections. The efficiency of drones also allows for quicker inspections, reducing the time and labor costs traditionally associated with roof inspections.

This speed and efficiency are particularly beneficial for large commercial properties or multiple residential units, where manual inspections would be time-consuming and costly. Moreover, the safety factor is significant. Drone infrastructure inspections eliminate the need for inspectors to physically climb onto roofs, reducing the risk of accidents and injuries. This aspect is crucial, especially in adverse weather conditions or on unstable structures. Drone inspections, thus, offer a safer, more efficient, and cost-effective solution for roof inspections.
