Below the Surface: Managing Geotechnical and Seismic Risks in Infrastructure Planning and Design

What lies below the ground surface can shape every aspect of what gets built above it. Geotechnical and seismic hazards can significantly influence infrastructure planning, design, construction costs, and long-term performance. As projects become more complex and expectations for resilience grow, identifying and understanding these risks early is essential to making informed decisions and avoiding costly surprises.

In this webinar, we will use practical examples and case studies to show how geotechnical and seismic considerations can inform infrastructure planning and design. We will examine how subsurface conditions and hazards—including ground shaking, liquefaction, and ground deformation—can influence project decisions and engineering solutions. We will also discuss how the level of investigation and analysis can be tailored to project needs and evolving design requirements. Attendees will gain insight into practical approaches for identifying hazards early, understanding their potential consequences, and developing mitigation strategies that support efficient designs and more resilient infrastructure.
