Tunnel surveying is a multi-disciplinary task. See http://underhill.ca/land-surveying-se... . This video shows a short train ride to our work site. Turn your sound down, as this ride was deafeningly loud! Underhill Geomatics provided a number of tunnel survey services to the Greater Vancouver Regional District Seymour-Capilano water tunnel.

The Seymour Capilano Twin Tunnels project are 2 x 7.4km tunnels for the treatment of the public water supply, in Vancouver BC Canada. We were traveling 5.6 km to a specific place within the Raw Water Tunnel to perform a 3D laser scan.

Surveying services included:

- 3D Laser Scanning
- Engineering Surveying
- Plumbing Surveying
- Geodetic Surveying
- Computation and CAD Mapping

Underhill was hired to established azimuth baselines, check tunnel shaft plumbing , review of past tunnel surveys, provide precise control surveys, create as-built cross sections of the tunnel, and survey sections using 3D laser scanning.
