Slightly different office to most
Seems most surveyors on here work mainly in the lovely great outdoors so figured I'd share my typical office
Those pics are great! Please keep us informed. ????
What are we looking at?
What tunnel boring are you working on? How long does your typical job last?

Sorry my bad I should have said.
They're taken from a TBM (Tunnel Boring Machine) It pushes forward (picture 2) and essentially cuts into the earth and lays rings behind it creating the tunnel.
The total station is used to provide position for guidance system which the pilot operating the machine uses to follow the tunnel alignment.

It's for a high-speed rail in the UK. There's a few tunnels to construct on this section in total 5 years probably (anyones guess is probably as good) but most of the time is preparation and temporary works rather than the actual tunnelling.
This tunnel in the picture should done in 5 months of actual tunnelling, but then we have to do one adjacent and do the cross passages and works after.
Very cool!!!
@alexandert That's pretty dang cool! Surmised it was something like that or a particle accelerator.
I believe I saw a report for an accelerator project that quoted measurements as x,xxx.xx millimeter. (Or if it was in Europe, x.xxx,xx mm.)
I watched an episode of Modern Marvels a few years back where they were adding tunnels to the subway in either London or Liverpool. The path of the new tunnel took the crew between two existing tunnels where clearance was critical. In addition to the underground mapping accuracy of the project which was phenomenal, they also had to provide continuous remote monitoring on historical buildings in the downtown area. An extremely interesting niche in the world of Land Surveying!!!
