This week, Seattle’s Sound Transit will start drilling a $2 billion, three-mile light-rail tunnel to connect the University of Washington, Capitol Hill and Westlake Center. The first TBM will be christened today near UW’s Husky Stadium and will drill the southbound tunnel towards capital hill. Another TBM will start in parallel with the first in June, excavating the northbound tunnel. A third TBM will come into service later to excavate the first tube of the 1-mile route from Capital Hill to Westlake center. It will be extracted from a pit at the end of the bore, and returned to dig the other parallel tube. [Source: Seattle Times Newspaper via ASCE SmartBrief. Image: Alan Berner / The Seattle Times]

Comments Off on Second Issue of International Journal of Geoengineering Case Histories [Official This Time]
The International Journal of Geoengineering Case Histories has formally announced their second issue. Apparently when I posted about it previously, they had only two of the four papers.
This second issue contains four case histories that come with additional downloads. In particular, check out Dr. Edmund Medley’s Paper on the 2006 Hawaii Earthquakes. He has some neat photos including some in 3-D (more about his 3-D photos).
