September saw us carry out surveys at two bridges in Scotland. The purpose of the survey was to capture above water and below water details, specifically areas of undercut and missing concrete bag work. We carried out an out of bank topographic survey, full terrestrial laser scan of the bridge abutments, piers and deck. Below water details were captured by a 3D sonar scanner. Deliverables consisted of topographic survey detailing bridge layout (including deck), bed levels (from sonar scan), elevation drawings, laser and sonar scan point clouds. In addition, images from the point cloud were created detailing dimensions of areas of undercut and scour. We also issued a multitude of photographs and survey report covering control established and accuracies achieved.

If you have a bridge or underwater structure that would benefit from a higher level of detail than would ordinarily be obtained by diving or a standard scour survey then please contact us for a chat. We can carry out bridge surveys to pretty much any specification you need. With RISQS approval railway structures are a speciality.
