Bridges
Drones capture data from bridges in ways vastly superior to the traditional techniques often used now. Traditional methods can provide a spotty and incomplete record, while drones can capture a full digital record of a structure. Drones can also help inspectors gather far more detail than conventional methods. They can fly close to structures and get good vantage points that might be difficult or impossible to reach. Depending on the bridge, cost savings vs traditional inspections can be 40 to 60 percent.

We can provide a complete map of the site with GPS points, in 2D and 3D, allowing accurate measurements of distances, surfaces and elevations. Photogrammetry software also generates elevation models such as digital terrain models (DTMs) and digital surface models (DSMs).
​
These models, or "Digital Twins," provide a detailed overview of the bridge's condition. The model can be used to extract images of specific locations on the bridge, providing details that can be missed with traditional methods.This helps to provide a not only a “big picture” view, but also an exact image of the structural conditions.
​
Also, the lane closures often needed for conventional bridge inspections can lead to traffic detours and traffic jams. Drones are a less expensive way to get similar results to traditional bridge inspections, without dealing with traffic.
