Piers of highway bridges over rivers are vulnerable to hydraulic damage caused by flood, hurricane, and instability of the riverbed causing movement and settling of the piers. Resensys High Precision tilt SenSpots sensors provide an ideal solution for structural health monitoring of such piers. In june 2014, Resensys SenSpot sensors were used on several piers of East Capitol Bridge Across Anacostia River to monitor their movement, settling and and deflections. Due to the bridge crossing the Anacostia River, a bucket boat was used for installation. SenSpots are bolted to the pictures for higher accuracy.
