NEESinc Mission 2: Earthquake Risk Mitigation
• Engineering/Construction of Resilient Infrastructure is Best Strategy:– Complements land use, earthquake preparedness, and emergency response – Great strides have been made but Cost-Effectiveness is still an issue– From prescriptive codes to performance-based design
• Success Requires:– Effective Design Tools for Hazard ID Coordination– Cost-Effective Engineering Solutions Research– Political Skill and Will Leadership– Good Construction/Maintenance Practices Partnership
