Every major infrastructure project is built on uncertainty. Beneath every foundation, tunnel, bridge, dam, highway, and underground structure lies a subsurface environment that can never be fully observed. Yet critical engineering decisions—and often billions of dollars in investment—depend on understanding this hidden ground well enough to design, construct, and operate safely. Designing Infrastructure for Uncertain Ground presents a practical framework for integrating geological uncertainty into infrastructure engineering. Rather than treating site investigation as a routine data-collection exercise, the book demonstrates how geological interpretation, ground investigation, engineering design, construction monitoring, and risk management can be integrated into a unified decision process. Drawing on lessons from tunnel collapses, foundation failures, landslides, and other major infrastructure projects, the book explains why technically sound designs can still fail when geological uncertainty is underestimated. It introduces the Geology-Aware Infrastructure Design Framework (GAIDF), which helps engineers incorporate subsurface uncertainty into investigation, design, construction, monitoring, and project governance throughout the infrastructure lifecycle. Bridging engineering geology, geotechnical engineering, structural engineering, risk engineering, and project management, this book provides practical guidance for designing infrastructure that is safer, more resilient, and better prepared for the uncertainties of the ground. Written for civil and geotechnical engineers, engineering geologists, tunnel and mining engineers, infrastructure consultants, researchers, graduate students, and project professionals, this book serves as a practical reference for modern infrastructure engineering.
