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.
UC Berkley has a bunch of lectures online, including three geoengineering themed ones. It appears that they were all from lectures given as a part of the 27th Annual GeoEngineering Distinguished Lecture Series on May 8, 2009. So if you have an hour plus to kill per lecture (and I haven’t yet), you can check out one of the following.
