Research Regarding Formulation of Guidelines for Underground Usage Associated with Urban Development

It has long been pointed out that the basic guidelines in the form of an underground utilization master plan and underground utilization policy are necessary for the effective utilization of urban underground spaces. Therefore, the Urban Underground Space Center of Japan (USJ) organized a subcommittee to investigate relevant cases in Japan and overseas to confirm the necessity for the formulation of the basic guidelines. In order to prepare the guidelines, we presented a proposal to discuss what topics should be included and how to organize the guidelines. The results thus obtained are summarized as preliminary for the guideline (draft). In addition, we chose a model district urban development in which underground space is assumed to be utilized, and at the same time, we checked on the adequacy as a guideline. As a future topic, it is confirmed that the guideline should have the consistency with various relevant systems and its applicability to the master plan for the underground development. This report summarizes the results of this research.
