Fishbeck was employed by the Blue Water Bridge Authority to be a part of a team to complete a scanning project for the Southerly Bridge Span over the St. Claire River. It was critical to get an accurate depth of concrete so crews would not mill into the membrane within the deck. Fishbeck used its terrestrial 3D scanner to capture the underside of the bridge while another team drove over the top of the bridge with a mobile scanning unit to capture the road surface. The two scan data sets were merged to create a model of the bridge, allowing designers to work with a very accurate drawing to gauge thickness of concrete. The scanning was completed on a Sunday morning while wind speeds and traffic volumes were very low. In total, Fishbeck completed 60 high-definition scans to map the underside of the bridge. Horizontal and vertical control were critical in merging the datasets to create the most accurate representation of the surface and features of the bridge span.
