Social infrastructure plays a critical role in sustainable development, so it is important to explore and understand the relationship between infrastructure, society, economy, and the environment. As such, interdisciplinary and internationally-oriented research is indispensable for tackling these multidimensional issues. This laboratory aims to provide education and carry out research activities on the development and application of evaluation methods, planning and design tools, and management strategies for the sustainable development and maintenance of social infrastructure, with the goal of contributing to a more sustainable world.
