Detailed Inspection Surveys
Trimble 3D laser scanners and total stations collect rich detailed 3D positions of detects and possible structural flaws in existing tunnel infrastructure enabling stakeholders with informed decision making.
High-Resolution Asset Data Collection
Trimble Mobile Mapping systems provide high-resolution scanning and imagery of tunnel infrastructure that provide operators with the tools to locate and manage critical tunnel assets.
Big Results in a Small Space
California-based Towill, Inc. was called to provide precise information on the interior of roughly 1,800 ft (550m) of the active, pressurized waterline. In addition to determining the horizontal and vertical alignment of the pipe, they needed to provide data on the pipe’s ovality, or deformation from its original circular shape caused by external loading at the surface. Engineers decided to use slip-lining to install a new pipe inside the existing water main. (In slip-lining a new carrier pipe is inserted inside an existing pipe to repair leaks and provide structural integrity.
