Guest Editorial on Geotechnical and Structural Engineer Collaborations: 87 Corrections: In the May/June issue Profile, we said that Peter Nicholson was consulting at the Herbert Hoover Dike, working with Geoconsult, which was retained by the US Army Corps of Engineers. Donald A. Bruce wrote that he put together and is president of, an ad hoc group called Geosystems LP that worked for the Corps, and included Nicholson, Pete Cali and Stephan Jefferis. Bruce has no affiliation with Geoconsult. An error appeared in the May/June issue in an article on the February ICOG meeting. On page 17, in the last paragraph, middle column, the first sentence about the tunnel in Australia should have stated the following: “To facilitate structural remediation of the invert, engineers installed some 5,200 permanent ground anchors in the underlying Melbourne mudstone to tie down 160 panels over a 2 km (1.24 mi) length of the concrete invert, …” The 5,200 grouted anchors were not corroded and were the solution, not the problem. We apologize for these errors. Virginia Fairweather, Executive Editor, DFI magazine.
