The US has more than 900,000 bridges. According to regulation, each bridge requires inspection every two years to ensure that there are no cracks, rusting, or other damage. This means that every day, 1,232 bridges need to be inspected. Inspection of such bridges requires a crew of inspection professionals, heavy machinery with lifts, people rappelling from dangerous heights, resulting in each inspection taking a few days.
And this is only to understand if there is a problem! Infrastructure inspection, which can include bridges, pipelines, electrical grids and other facilities, is crucial for structure usage and safety, yet it is expensive, time consuming and dangerous. Fortunately, new professional-grade drone inspection technologies can help alleviate these challenges.
