3D Scanning Used for Snow Shed Tunnel Improvements

As a teaming partner of Fehr & Peers (CDOT Region 3 and 5 Traffic NPS), Farnsworth Group managed spatial imaging and scanning of the snow shed tunnel located on US Highway 550 along Red Mountain Pass. 

Our team mapped the tunnel using a Trimble 3D scanning total station. Project control was established outside of the structure and scanning targets were placed on the interior structure for collecting high-density 3D scan data.

The scanning technology allows for true high-speed 3D scans providing high level measurements, high quality resolution imagery, and point cloud extraction. This project was the first of its kind in the Region and was a true test of the technology and its application for future projects. Our deliverables for the project included 2D CAD topographic planimetric drawings, scanning images and 3D digital terrain model.
