As you can probably tell, there have been a few cosmetic and behind the scenes changes to the GeoPrac.net website. Rest assured it is still one of the premier sites for news and articles related to geotechnical engineering, geological engineering and engineering geology. But the software that runs the site was in dire need of upgrades, both for security and ease of maintenance. The new look was a byproduct of those upgrades (long story).
There are going to be some growing pains with the upgrades, including some broken links and other glitches. I appreciate your patience as I work to sort them out and I ask you to do me a favor, and if you come accross a problem, drop me a note – .

7 years ago today, I wrote my first post for GeoPrac.net! It’s hard to believe I’ve been doing this for that long. I am grateful for all of the visitors, twitter followers, supporters, and of course sponsors that have made it possible for me to share high-quality news and articles for geoprofessionals. I look forward to another great 7 years.
Last year I highlighted a few of my favorite articles and blog posts. This year, I thought I would just go by the numbers to see what the most popular articles and posts have been over the years. Check it out.
On January 15, the National Transportation Safety Board released a safety recommendation letter report to the FHWA related to the I-35W bridge collapse in Minneapolis Minnesota that claimed the lives of 13 people and injured 145. The safety recommendations are based on the findings of an interim report from the FHWA Turner-Fairbank Highway Research Center that some gusset plates, components of the steel trusses, were undersized (not thick enough). This deficiency was confirmed to be a flaw in the design and not construction-related based on review of the original drawings from the 1960s and inspection of the wreckage. Whether this was a calculation error or a drafting error will perhaps never be known as only portions of the original design calculations were located. But the point is that it was never caught by any reviewers.
When this event first happened back on August 1, I remember being very shaken up by it. After my initial sadness for the victims of the accident, my first thought as a geotechnical engineer was: â€œwere the foundations at fault.â€ As more information came out, it quickly became evident that the failure did not have anything to do with the foundations but that it was related to the superstructure of the bridge. But this still was something that profoundly affected me. (Continuesâ€¦)
