Confidential Client | Slope Failure Survey of Road Next to Canal
Patrick provided professional surveying services at a slope failure along a service road near a steep embankment next to a canal in the Midwest. The road was about 20 feet above the water and part of the road was lost into the slope failure area. Patrick utilized a Seafloor HyDrone drone boat with a single beam sonar to collect bathymetry water depth readings, as well as a ground survey topo, to ascertain the natural adjacent slopes and the changed terrain within the slope failure. Due to safety considerations with the near vertical slopes, a Riegl VZ-400i terrestrial LiDAR scanner was utilized to capture the ground, especially given the challenges to reach it by foot. The survey was drafted with a surface model such that the engineers could design a solution to stabilize the slopes and protect the road.
