Safer, more cost effective and more detailed bridge inspections is possible with drones.At our municipality, we have 393 bridges that fall under the City's responsibility, and they range from signature bridges over the North Saskatchewan River (~220 meters wide) to timber pedestrian bridges in communities.
Regular detailed visual bridge inspections, performed by trained and certified inspectors, are an essential aspect of maintaining our infrastructure in a safe and serviceable condition
Some bridges can be hard to inspect due to structure type and elevation, traffic and inaccessible areas found at some bridge sites. Visual inspections can be costly, and sometimes hazardous and require platforms, rope access, harnesses, traffic disruptions and a significant amount of time.
Our bridge maintenance team decided to pilot the City's first Unmanned Aerial Vehicles (UAVs) / Drone inspection in May 2020, so that a more thoroughly inspection of the underside of a bridge could be accomplished at of inaccessible areas. The team was pleased with the close-up and high resolution image quality from their first inspection.
With the successful pilot approved, the team kept completing more inspections of several bridges crossing the North Saskatchewan river using the Drone during the summer of 2020.
This innovative method enhances regular inspections and monitoring of Edmonton's bridges, hence improving the maintenance and service life of the bridge structures.
Of course you'll need a condition classification for the variety of the situations encountered, such as disappeared track bolts, cracks in concrete pillars and scouring in the river bed, in order to prioritize in succeeding activities yet that is common stuff for you, being in the Drone business, assumably.Best regards,Geert Henk
