Missouri S&T (known as UM Rolla a while back) has a number of courses that are available through their YouTube channel. One such course is their GeoEng 341 course, Engineering Geology and Geotechnics taught by Dr. David Rogers. You can watch the entire series of 15 lectures totaling over 32 hours on You-Tube! Check out the first lecture below.

Tunnel Collapse Caught on Video
According to the site Geotechpedia, this tunnel failure occurred on November 29, 2016 around 9am (local time?). The tunnel is located in Yusufeli district of Erzurum in northeastern Turkey. It is somehow related to the […]

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.

Geo-companies in ENR’s 2017 Top 500 Design Firms
ENR’s annual top 500 design firms list for 2017 is out. These rankings are based on revenue for design services in the previous calendar year. Last year I extracted a subset of the list to see rankings of firms that are strong in geotechnical / geological related services, so I decided to do it again this year. I included firms that self-identified as geotechnical firms, as well as engineering firms that I know to have a strong geo emphasis. I’m sure there are some that I missed. I also included some of the major A&E firms that provide these types of services. Accordingly, it’s still a bit subjective on who is included. So here is the list of top Geo-Companies of 2017 (along with their change in ranking relative to 2016):
- 1 – AECOM, Los Angeles, Calif. (No change from 2016)
- 3 – CH2M, Englewood, Colo. (No change from 2016)
- 5 – TETRA TECH INC., Pasadena, Calif. (+2)
- 7 – AMEC FOSTER WHEELER, Atlanta, Ga. (-2)
- 8 – HDR, Omaha, Neb. (+1)
- 10 – STANTEC INC., Irvine, Calif. (+8)
- 13 – ARCADIS NORTH AMERICA/CALLISON RTKL, Highlands Ranch, Colo. (-1)

There are so many projects and engineers who could benefit from listening to Rogers. There is a science to it and identifiers that can tell the engineer how the soil has responded over time.
