A nifty BIM-type view of the proposed bored tunnel for Washington SR 99, the tunnel to replace the aging Alaskan Way Viaduct along Seattle’s waterfront. It’s pretty neat to see the piles and foundations for other structures and major utilities as the bore passes by them. A little on the longer size, at around 5 minutes.

Rockfall Protection Videos from G.T.S.
More videos! French Company G.T.S. has posted some great videos on rockfall protection systems on their YouTube channel. I don’t speak French, so I can’t give you any more info on the company (although their website looks like it has plenty of info!). But the videos cover the preparation of, drilling for, and installation or rockfall protection fences and barriers as well as a couple of general rockfall ones. They just have video with background music, so no worries about a language barrier. You can watch the installation video below.
