Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art. Volume 8: Public Communication and Awareness / Risk Management, Contracts and Financial Aspects contains the contributions presented in the eponymous Technical Sessions during the World Tunnel Congress 2019 (Naples, Italy, 3-9 May 2019). The use of underground space is continuing to grow, due to global urbanization, public demand for efficient transportation, and energy saving, production and distribution. The growing need for space at ground level, along with its continuous value increase and the challenges of energy saving and achieving sustainable development objectives, demand greater and better use of the underground space to ensure that it supports sustainable, resilient and more liveable cities. The contributions cover a wide range of topics, and is a valuable reference text for tunnelling specialists, owners, engineers, archaeologists, architects, policy makers, decision takers and others involved in underground planning, design and building around the world, and for academics who are interested in underground constructions and geotechnics.
