Arup lead the seismic evaluation of 27 high-risk court buildings across the State of California. The study includes developing several conceptual retrofit schemes and associated construction costs for each court building. The reduction in seismic risk for each retrofit scheme is quantified in terms of casualties, downtime, and repair costs using a fully probabilistic approach based on FEMA P-58 and REDi. Cost-benefit analysis is performed to identify optimal retrofit options and help prioritize investment strategies across the portfolio.
