Core Viewpoint - Shenzhen is accelerating its development of underground spaces to create a vibrant three-dimensional city, as outlined in the "Shenzhen Underground Space Resource Utilization Plan (2025-2035)" [1][10]. Group 1: Overview of the Plan - The plan includes 48 key development areas for underground space across various districts, with the most in Nanshan District (10 areas) and the least in Dapeng New District (1 area) [3][4][5][6][7]. - By the end of 2020, Shenzhen's total underground space was approximately 104 million square meters, with a per capita underground space of about 5.9 square meters [1].

Core Viewpoint - The development and utilization of underground space is crucial for addressing urban development bottlenecks in China, as highlighted by the recent policy document from the Central Committee of the Communist Party and the State Council [1][2]. Group 1: Systematic Thinking - Urban infrastructure must be managed as a cohesive whole, integrating underground space as an organic part of the city [1]. - A full lifecycle management system from planning to construction and operation is essential to maximize the potential of underground space [1]. - Coordination among various infrastructure systems such as transportation, energy supply, communication, and drainage is necessary for effective underground space development [1]. Group 2: Forward-Thinking - Urban infrastructure should be designed with future developments in mind to avoid obsolescence shortly after completion [2]. - Sufficient capacity should be reserved in underground space design to prevent the need for frequent renovations [2]. - Infrastructure should be adaptable to new technologies, ensuring compatibility between old and new systems [2]. Group 3: Bottom-Line Thinking - Emphasis on safety measures for critical utilities like gas and water is vital, with a focus on establishing emergency response systems [2]. - The development of underground space must not overlook safety management in less visible areas [2]. - A robust standard system for underground construction and operation should be established to ensure quality and safety throughout the project lifecycle [2].

Group 1 - The importance of safety and resilience in urban environments is emphasized, particularly in high-rise buildings and complex underground spaces, to ensure public safety during disasters [1] - Basic principles for earthquake emergency response include staying put during shaking and quickly evacuating afterward, with specific recommendations for individuals on higher floors [1] - Urban flooding is highlighted as a common natural disaster, with advice on avoiding hazards such as electrical facilities and deep pits during such events [1] Group 2 - Underground spaces like subways and parking garages are essential for urban development, necessitating their safe and efficient operation [2] - The need for enhanced resilience design and disaster response capabilities in underground spaces is stressed, particularly during the planning and construction phases [2] - Key measures for flood prevention in underground spaces include establishing monitoring systems, ensuring drainage systems are clear, and avoiding the disposal of waste that could lead to contamination [2]
