Tunnel Beneath the Bay

For decades, California's Hetch Hetchy water system has supplied water to the San Francisco Bay Area. But the aging system is nearing the end of its useful life and is seismically vulnerable. Constructing a solution requires accurate, nerve-racking surveying.

The New Link

A team of Belgian surveyors seamlessly adopt a new class of instrument midway through a large, multi-modal transportation project in Belgium, after problems arose from reliance on legacy surveying tools and methods. Adoption of the Trimble SX10 solved the issues and provided the surveyors with new options for rapid collection of 3D data.
