nology. Harnessing the technologies available today can bring long- overdue productivity improvements to tunnel design, construction, and maintenance. With connected construction, siloed workflows and teams become a thing of the past. In addition to reducing the risk of human error and enabling faster, more efficient workflows, technology fills the gaps that historically exist in tunnel construction, linking teams across disciplines and locations—from the office to the jobsite to the fabrication shop—in ways that simply aren’t possible with traditional, typically manual tools and methods.

The Trimble SX10 scanning total station combines the robotic total sta- tion and 3D laser scanning abilities into one instrument. This provided construction surveyors with the ability to collect automatically georef- erenced point cloud data of the tunnel lining to verify the construction process vastly reducing processing time in the office. Combined with Trimble Business Center office software, surveyors were able to au- tomatically remove noise from the collected point cloud and generate detailed as-built reports. A New Way of Working More efficient tunnel design and construction require collaboration, automation and data sharing, all made possible by advances in tech-
