February 2016 – Rail Bridge Inspection

During a recent flood event, a rail bridge in the Burdekin area was damaged by the high volumes of water and debris travelling down stream. NQ UAV went to investigate the bridge to demonstrate the abilities of an RPAS to conduct a rapid asset inspection of infrastructure after a natural disaster. Our experienced crew were able to operate within meters of the structure to take high-resolution photos sections that had suspected damage from the flood event. In the photos above, you are able to clearly count the number of threads, the condition on the bolt, see oxidation of plates and oxidation of bolts holding the step ladders in place. All of this could be seen on our HD monitor next to the crew and would allow the site engineer to start making decision or get us to re-focus on sections that require more detailed inspections.

From this inspection, we were able to demonstrate a safe operation around a damaged rail bridge without putting any one at risk all the while providing the site engineers with the resources to make an informed decision before sending someone on to conduct any form of contact based inspections or repairs.
