This lecture covers integrated risk management in civil engineering, focusing on government policies, societal aspects, and the role of scientists in risk analysis and management. It discusses the legislative basis for risk management, decision-making processes, and the precautionary principle. The lecture also presents a case study on the 2009 Aquila earthquake in Italy, where scientists faced manslaughter charges for downplaying risks, leading to a controversial legal process. Lessons learned from this case and the importance of comprehensive risk management tools are highlighted.
