October 14, 2020 – Online David Paul delivers a virtual talk on the “Dam Safety program and positive impacts on critical infrastructure. The 2020-2021 DFI Traveling Lecturer, David Paul, presented a virtual lecture, “Forty Years of Dam & Levee Safety” to the ASCE New York chapter. The lecture focused on the failure of the Teton […]

This series of three webinars, brought to you by DFI’s Testing & Evaluation Committee, demonstrated how foundation testing conducted during the design phase can provide data that optimizes foundation designs and construction procedures, thereby SAVING MONEY while increasing the quality of the constructed foundation.

This one-day event highlighted effective application of deep foundations, ground improvement, and soil mixing for stabilization of slopes and excavation support. Presenters shared current technologies, design concepts, research, and case histories for challenging slope and landslide repairs, excavation support and slope stabilization projects using deep foundation and ground improvement methods.

This webinar presented the background, resources, applications, construction work flow and management considerations required to design and construct effective energy foundations.

The presentation examined the increase in density in the vicinity of drilled displacement piles when they are installed in materials that exhibit granular behavior. The increase is most pronounced in loose to medium dense materials and can be utilized to mitigate liquefication and increase the foundation response stiffness of the mass of the material penetrated.

Virtual SuperPile ’20 gathered design professionals, engineers, contractors, researchers, material and equipment suppliers, and government agencies involved in the design, construction and research of piling solutions for foundations, excavation support and slope stabilization.

The presentation focused on how the development of more powerful and robust installation platforms has made it feasible to install cast-in-place piles into materials once considered too resistant for the system. This lecture reviews current installation platforms and tooling and presents case histories for installation in soft limestone, partially weathered rock, shale and glacial till.

DFI Technical Committees were as busy as ever preparing publications, seminars, workshops, and videos on all aspects of deep foundations. To showcase the initiatives and to invite more participation, DFI organized a Midyear Committee Week.
