Abstract:
PLENARY SESSION 4: Built on Better Ground
Moderators: Chris Woods, P.E., G.E., P.Eng, BC.GE. | Menard USA and Roberto Nevarez, P.E. | GeoEngineers
This panel discussion, part of DFI’s S3 2026, will examine the expanding role of ground improvement techniques in slope stability and excavation support, emphasizing practical application, innovation, and collaboration across disciplines. As projects increasingly confront difficult ground conditions, limited footprints, and stricter performance requirements, ground improvement has become a vital component in achieving safe, efficient, and constructible solutions.
Rather than focusing on isolated roles, the panel will collectively explore how design, analysis, materials, and construction intersect to shape successful outcomes. Discussion will center on how project teams evaluate and select appropriate ground improvement methods, integrate numerical modeling with field realities, and adapt designs to evolving site conditions. The conversation will also highlight how advances in digital tools are enabling better prediction and risk management, while material innovations are enhancing performance and constructability. A key theme will be the importance of collaboration and feedback loops between design and construction to reduce uncertainty and improve project delivery. In addition, the panel will address sustainability considerations, including reducing carbon footprints through optimized designs, minimizing material usage, reusing in-situ soils, and selecting environmentally responsible ground treatment solutions.
Through case studies and interactive dialogue, the session will address challenges such as uncertainty management, integration of analysis with construction practices, and balancing technical, economic, and environmental objectives. Attendees will gain practical insights into leveraging ground improvement strategies to deliver resilient, cost-effective, and sustainable solutions for slope stabilization and excavation support.
