This textbook introduces the fundamental concepts of probability, risk, and uncertainty, and shows their relevance in civil engineering projects. With an emphasis on applied probability and statistics, the book aids students in developing an intuitive understanding of the methods to apply in practice. Drawing from real-world examples, readers are introduced to risk assessment and analysis techniques, enabling them to identify, evaluate, and prioritise potential risks. It gives realistic examples of how spreadsheet tools such as Microsoft Excel can be used to solve problems involving probability, and practical approaches such as Monte Carlo simulations and decision trees are explained in a clear, accessible manner, empowering students to make informed decisions under uncertain and variable conditions. The book also emphasises the importance of effective communication, equipping students with essential skills for working in multidisciplinary teams and with different stakeholders. Risk and Uncertainty for Civil Engineering serves as an introductory textbook for undergraduate students in civil engineering, as well as a useful primer for postgraduate students.
