The FHWA’s Advanced Geotechnical Methods in Exploration (A-GaME) series of webinars is part of their Every Day Counts Initiative. For the past year and a half or so, they have been organizing these excellent webinars on the state of the art and practice in geotechnical investigations. Now, those webinars are on YouTube courtesy of the Deep Foundations Institute. There are currently 10 A-GaME webinars posted, including one of my favorites on Measure While Drilling or MWD technology (see below).

A report has been released by the NYSDOT on the Scoby Hill Landslide which has impacted a 4.2-mi improvement project of Route 219. The report, dated May 20, 2008 was headed to an FHWA peer review panel.
The Feds were call in to help because of the unusual nature of the landslide. The slip surface is very deep, approximately 30-m (100-ft) below the surface and below all of the design phase investigations. And the remolded shear strength of the silty clay forming the slip surface was only 12-14 degrees.

The FHWA has recently updated its geotechnical engineering site related to their annual State Geotechnical Workshops. All regions with the exception of the Southwest have their Workships this September and October. The next Southwest Geotechnical Engineers Conference will be in April of 2008. The 2007 SGEC was on April 23 – 27, 2007 in Overland Park, Kansas. They have posted PDF versions of the presentations at the conference on their FTP site. Read on for the dates of the upcoming workshops, as well as a link to the FHWA site and the presentation downloads.
