In July, BDI performed nondestructive evaluation (NDE) on nearly 1M square feet of bridge decks in Alaska. The data collected with SounDAR and High-Resolution Imaging (HRI) will be utilized to identify areas of delaminations, cracking, patches, and spalling. We are also collecting millions of square feet of deck NDE throughout the country this fall using SounDAR, 3D-Radar (GPR), HRI, and Infrared Thermography.
SounDAR, BDI’s Deck Acoustic Response (DAR) System is an automated bridge inspection method used to identify and quantify areas of subsurface degradation including delamination, debonding, and spalling. SounDAR utilizes a novel analysis method that replicates the function of the human ear by detecting changes in frequency, amplitude, and relative energy distribution. In this way, it provides an automated NDE method similar to manual sounding at a fraction of the cost.
