Underground Space Development and Utilisation (USDAU) and construction of necessary supporting infrastructure are ongoing throughout the world. Although most of the urban areas are already densely settled with buildings above and below the ground, there is still a pressing need to construct new infrastructures between or beneath the existing ones. Mitigating their impact upon the existing structures and surrounding environment heavily depends upon the construction method and information modelling of infrastructure. A consensus regarding how to address the engineering challenges, however, has not yet been reached.

Since there is a great demand for the new techniques of tunnel excavation and information modelling of underground infrastructure, state-of-the-art research focusing on USDAU technology are urgently needed in order to develop solutions to these challenges.

In this Special Issue, we encourage original submissions concerning USDAU technology and especially welcome those relating to novel techniques and outstanding applications of underground information modelling, smart infrastructure monitoring, mechanised excavation of tunnels and No-Dig technology.

Potential topics include but are not limited to the following:

• Information modelling of underground infrastructure
• Smart infrastructure monitoring
• Mechanised excavation of tunnels
• Novel technology of underground space development
• No-Dig technology
• Tunnel blasting vibration control technology
• Sustainable development solution for environmental impact mitigation
