WHOLE LIFE BUILT ASSET MANAGEMENT MODELLING FRAMEWORK: Integrating mitigation to earthquake induced liquefaction disaster events into strategic built asset management planning

Recent events have demonstrated that Earthquake Induced Liquefaction Disasters (EILDs) are responsible for significant structural damage with, in some cases, EILDs accounting for up to half of the economic loss caused by earthquakes. With the causes of liquefaction being largely acknowledged, it is important to recognise the factors that contribute to its occurrence; to estimate the impacts of EILD hazards; and to identify and implement the most appropriate mitigation strategies that improve both building/critical infrastructure and community resilience to an EILD event. The LIQUEFACT project adopts a holistic approach to address the mitigation of risks to EILD events. The LIQUEFACT project sets out to: • Achieve a more comprehensive understanding of the impacts that EILD events have on the resilience of communities and buildings/critical infrastructure on which they rely; • Achieve a more comprehensive understanding of the range of mitigation techniques (technical, operational, managerial and organizational) that can be implemented to improve the resilience of communities and building/critical infrastructure to EILD events; • Develop more appropriate mitigation techniques (technical, operational, organizational and managerial), for both European and worldwide situations; and • Develop a Resilience Assessment and Improvement Framework (RAIF) to allow community and building/critical infrastructure stakeholders to make the business case for mitigation interventions.
