Underground urbanization aids sustainability by contributing to the optimization of land use plans, diversification of urban functions, safeguarding of utility supplies and enrichment of social life. Underground space as a valuable land resource can be integrated into a general urban resources management scheme and development policy, by rationalizing resource supply according to economic demand, and by coordinating stakeholders from the public administration, private developers and users. After benchmarking best practices in administration and management, from seven cities (Helsinki, Singapore, Hong Kong, Minneapolis, Tokyo, Shanghai and Montreal), critical success factors are extracted to guide a pilot project implementation.
The way to incorporate underground space planning into conventional urban planning process is exemplified by a pilot project of Suzhou City in China, which investigated thoroughly the supply potential of its underground space resource as well as the demand potential of the urban economy on underground space development. The core value of the case study in Suzhou City is based on active involvement of provincial and municipal governments, who supported territorial data collection, administrative consultation and the development of GIS-based decision-making tools. The typicality of the present case study refers to an old Chinese city with a modern Central Business District owning important economic functions for the Yangtze region. Underground Space in Suzhou City is considered as a new land resource manageable with a quantitative and spatial inventory for future allocation. An economic model putting forward a "3D land value" index will be illustrated for underground building projects. This index helps to regulate underground space development according to the resource supply potential and economic demand potential.
This strategic framework including potential analysis, local implementation and instrumental innovation was developed from an international cooperation program named "Deep City project" between Switzerland and China. Further discussions on considering societal impacts affected by underground space use indicate future research directions for underground space operations management.
