The Role Of Drones In Infrastructure Inspection
The Role Of Drones In Infrastructure Inspection – Aging infrastructure is an expensive and dangerous problem for many communities across the United States. For New Jerseyans, this issue hits too close to home. The American Society of Civil Engineers (ASCE) reports that driving on roads in need of repair costs New Jersey drivers $713 a year and that 7.8% of New Jersey’s bridges are structurally deficient.
There are over 6,000 bridges in New Jersey. With many of them in need of repair, community and government leaders are looking to private companies for new technologies and solutions. The cost-saving and time-saving solution proposed by The Drone Life is the implementation of drone-based bridge inspections.
The Role Of Drones In Infrastructure Inspection
Drones allow close access to hard-to-reach places, such as the underside of bridges, while capturing high-resolution images that can be used to assess potential structural deficiencies. Remotely controlled drones provide 3D and infrared models of bridges and can identify areas of corrosion, abrasion and cracks.
The Major Advantages Of Using Drones For Bridge Inspections
This data allows engineers to accurately decide whether to maintain, rehabilitate or replace aging bridges. During repairs, drones can be used to track progress, provide continuous updates, and compare before and after.
There are significant benefits to using drones for bridge inspections, including improved worker/commuter safety, faster and easier inspections, more detailed data collection, and reduced costs. These are just some of the benefits of drone bridge inspections. In the remainder of this article, we detail what we believe to be the top 5 benefits of using drones for bridge inspections.
Traditional bridge inspection requires expensive and dangerous equipment and large work teams. The most common equipment used during bridge inspection is the snooper truck, which uses a multi-joint arm and platform to suspend workers under the bridge while the truck is parked on the bridge deck.
This can be especially dangerous on bridges with heavy traffic or over fast-moving waterways. In some cases, in an even riskier approach, workers fly from the top of the bridge on a rope.
Using Drones To Inspect Infrastructure For Safer And More Sustainable Operations
Drones offer a safer solution for bypassing inspection equipment. The drone can be controlled remotely from the ground with just a two-man team consisting of a single drone operator and a designated visual observer. Both can do their work safely from the ground.
Additionally, a licensed drone pilot will know how to operate a drone safely and legally around traffic and pedestrians, and will receive an exemption if necessary. They also carry drone insurance to protect themselves and customers from liability.
It can take hours for a scouting truck to arrive and secure the workers in safety gear. A drone can be set up in minutes and start collecting images as soon as it’s in the air. The inspector does not need to be physically transported to the spying truck before data collection. Instead, the drone can quickly maneuver around the bridge, collecting data on the fly while the drone operator remains on the ground.
Some off-the-shelf software even allows images to be instantly assembled into 3D and infrared models, so decisions can be made more quickly. A further time saving is that the need to close bridge traffic during the inspection is reduced. In some cases, drone inspection may allow traffic to continue as normal without the need to close lanes or stop traffic.
Elevating Efficiency: How Drones Are Transforming Infrastructure Inspe
During traditional bridge inspections, observing the underside of the bridge is a big problem, because it is very difficult to place the workers there and it is difficult to take pictures from an angle. Top-mounted camera drones offer a solution. They can easily fly under bridges and look straight up, capturing data from every vantage point. This is especially important during bridge inspections, as side and bottom views of the bridge can reveal the most critical information about the condition of the bridge.
The Federal Highway Administration reports that traditional bridge inspections cost between $4,500 and $10,000 per bridge. In addition to the price of equipment and labor, this also includes the costs of lane closures and traffic disruptions.
When drones are used, bridge inspection costs are dramatically reduced. According to drone manufacturer Skydio, the cost per inspection can be reduced by up to 75%. Drones can fly near and around bridges without disrupting traffic, eliminating the costs of lane closures and traffic restrictions.
Also, a drone can be operated by teams of up to two people. Commercial drones require a licensed drone pilot and a visual observer. With a well-equipped drone, the drone operator can perform the inspection quickly, depending on the size of the bridge, in as little as one hour. With fewer workers working faster, drone bridge inspections are much cheaper than traditional inspections with a peeping truck.
How Transportation Departments Are Using Advanced Drone Technology For Infrastructure Inspections
Paired with drone software, data collected during drone bridge inspections can be easily stored and shared with other team members across departments and agencies. The automated software keeps the images organized and eliminates the need to go through each image individually with the human eye. Image analysis software allows engineers to quickly identify problems and turn data into professional inspection reports.
Beyond the initial survey and inspection, drones can be used continuously during ongoing bridge rehabilitation projects to monitor progress. New images can be taken to collect before-after comparison data and to ensure the job is properly completed.

In a pioneering move toward modernizing transportation practices, the New Jersey Department of Transportation (NJDOT) is a national leader in the use of Unmanned Aircraft Systems (UAS), or drones. By creating a dedicated drone program, NJDOT has not only embraced drone technology, but institutionalized it as a common practice that can open up many applications from accurate survey to incident response, revolutionizing the department’s approach in the Garden State.
Computer Vision Assisted Damage Inspection Using Drones
The Drone Infrastructure Control Support Act has passed the House and passed a major hurdle to become law. The bill would authorize $200 million in competitive grants to train and use American-made drones for critical infrastructure inspections, maintenance or construction projects.
A new drone infrastructure inspection grant bill is being debated before Congress. Here’s everything you need to know about it and what it means for the future of drones in infrastructure if it takes off.

Drones are unmanned aerial vehicles (UAVs) that can be controlled remotely by a human pilot or operated independently. They can be configured as quadcopters or hexacopters, or fixed-wing drones. Drones have been used for military purposes for over a decade. Today, drones are rapidly being adopted in the commercial and private sectors, as well as in people’s daily lives. Its growing popularity is prompting innovators and decision makers to explore the potential uses of this unique technological offering.
The possibilities of using drones are endless. They offer a safe, cost-effective solution for previously time-consuming or high-risk tasks typically performed by humans. Some concrete possibilities for the use of drones in the transport and energy sectors today:
Top 10 Commercial Uses For Drones
Drone technologies can improve the process of inspecting devices because the photos they take are very high-resolution, sharper than the human eye, and can be reviewed multiple times. These photos can be used to get a good quality picture of the condition of the devices. In addition, they enable enhanced security and protection with durable and flexible monitoring coverage of the transport network and ensure a quick response when a security-related event is detected.
Drones can also be connected to sensors to collect data. Today’s drones can be considered Internet of Things (IoT) devices because they operate over Wi-Fi. They can share data with other IoT devices and systems and provide real-time data as input to “big data” applications. This enables faster, more accurate business, decision-making and analysis in service offering and infrastructure development, and facilitates more efficient asset decision-making.
As technology advances, the ability of drones to perform increasingly complex tasks will also increase. One such example is that drones are expected to be able to recognize faces, allowing them to identify people. This naturally raises issues regarding people’s privacy and the reliability of facial recognition technology.
Legislation and Regulation: In many countries, the regulation of drones has been treated as an extension of the existing regulatory framework for the aviation industry. Drones are restricted to segregated airspace, prohibited from populated areas such as protected zones near airports and military installations, and must be operated within the pilot’s line of sight. These regulations are generally considered too restrictive and hinder innovation. The enforcement mechanisms are also inadequate. In order to unlock the wide range of benefits offered by drone technology, existing regulations require control and new safeguards in terms of vetting and licensing of drone operators and effective encryption or cyber security.
