Geo-Solutions would like to thank the Pittsburgh Geological Society and the Pittsburgh Chapter of ASCE’s Geo-Institute for allowing Dan Ruffing the opportunity to present at their joint dinner meeting held at Foster’s Restaurant on January 18, 2017. Dan’s presentation was titled “Slurry Supported Excavations for Geotechnical and Geoenvironmental Applications”. Dan would like to thank the 70+ engineers, geologists, and contractors that were in attendance for not only attending his talk, but also for asking thoughtful questions.
