Rapid urbanization in the twenty-first century presents numerous challenges and opportunities for city planners and civil engineers. The concept of resilient cities has emerged as a critical framework for addressing urban vulnerability and ensuring sustainable development. This chapter explores the integration of advanced technologies and civil infrastructure to create smart and resilient urban environments. By leveraging Geographic Information Systems (GIS), Internet of Things (IoT) devices, and sustainable design principles, cities can enhance their infrastructure resilience, improve residents’ quality of life, and achieve long-term sustainability goals. This comprehensive analysis includes case studies, theoretical models, and practical applications, illustrating how technology and civil infrastructure can be harmonized to develop smart urban spaces that are adaptable to environmental, social, and economic changes.
