Registration is Open for DFI’s S3: Slopes, Slides and Stabilization Conference: August 3-5 in San Francisco and Online 

May 27, 2021, Hawthorne N.J.:

Registration is open for DFI’s S3: Slopes, Slides and Stabilization Conference, August 3-5, at the Hotel Kabuki in San Francisco. The event is led by DFI’s Deep Foundations for Landslides/Slope Stabilization Committee and the DFI-ADSC Anchored Earth Retention Committee with contributions from seven additional DFI committees that support the subject matter.

The 2.5-day conference focuses on effective application of deep foundations, ground improvement, and soil mixing for stabilization of slopes and excavation support. Roberto Lopez, P.E., chief engineer of Malcolm Drilling Company, is the conference chair.

On Wednesday, August 4, and Thursday, August 5, invited speakers and other industry experts will provide presentations on the latest analytical and design methods and practical applications. California case histories will be highlighted, with an emphasis on deep mixing and ground improvement techniques. In addition, three on-demand presentations are available to attendees.

This event features three invited speakers. Ross Boulanger, Ph.D., P.E., University of California, Davis, will overview seismic research efforts with a focus on current initiatives; Rob Jameson, Malcolm Drilling Company, will review the last decade of deep mixing practices in San Francisco; and Mark Rice, Esq., McNeil Silveria Rice & Wiley, will address the legal and forensic considerations relative to landslides, causation and forensic analytics, as well as how post-slide investigations and legal resolutions can occur, with these steps often faltering due to inadequate initial investigations and “crime scene” capture.

The conference also features a 90-minute panel discussion and live webinar on appropriate modeling of groundwater in slope stability analyses. The discussion is being facilitated by Erik Loehr, Ph.D., P.E., of the University of Missouri-Columbia who is the trustee liaison for DFI’s Deep Foundations for Landslides/Slope Stabilization Committee. Providers of commonly used software packages will discuss, analyze and present solutions for the same real-world slope stabilization problem, highlighting the influence of groundwater variations on the solutions. 

The event includes an exhibit area where up to 30 DFI member companies have opportunities to showcase innovative products and services.
