New Techniques for Bridge and Structure Inspection

“Combining Scanning Sonar, Laser Scanning and Mobile Mapping to Provide New Techniques for Bridge and Structure Inspection.”

By Tom Card, LandScope Engineering Ltd

Summary of paper:
With regards to bridges and other underwater structures, owners, operators and the civils industry are continually challenged to understand the structure and condition of assets below the water line. New techniques in 3D sonar are now enabling high resolution, high accuracy point clouds to be collected underwater. This presentation will discuss the challenges faced in designing data collection programmes, understand the value of combining such with traditional laser scan (LiDAR) point clouds and appreciate the advantages of this rich resource over more traditional underwater inspection techniques.
