“…These were removed from the tunnel to a dump site, so that other activities could be carried out (e.g., spaying of concrete or assembly of stabilization devices). In the most recent international projects, there is an effort to reuse the materials that come from the excavation of the tunnel (Ritter et al, 2013.). Reusing this material can save non-renewable resources, avoid the creation of definitive dumps, limit the negative impact on neighbouring populations, and save energy by reducing the travel distance of these materials (Ritter et al, 2013).…”

In this case study, due to the vast amount of debris produced (400,000 m 3 ), it proved necessary to provide two dumping sites, one on each side of the Marão Mountain Range, to temporarily store the material.…”

“…However, the costs involved when the height is substantial make it impossible to choose this way (Hunt et al, 2016). There is no denying that underground construction is increasing all over the world (Ritter et al, 2013) and there is an undeniable link between the population growth and the development of underground infrastructures. That can be seen in the cities of Stockholm, Tokyo and Paris (Bobylev, 2009), to name but a few, which are betting on this kind of work due to its importance for economic development (Admiraal & Cornaro, 2016).…”

The role of underground construction for the mobility, quality of life and economic and social sustainability of urban regions

2017

Tunnelling has been used for several purposes for thousands of years. In the coming years the world's population will increase in the urban areas. So, the urban centres will have to adapt, in order to guarantee that their future population will have the necessary and sustainable growth. Due to the constraints for surface construction, also connected to environmental issues, this population growth will imply a greater use of the underground. With this optimal growth, the population of the cities will have better mobility, quality of life, and economic and social sustainability. In a first phase, this report will present a historic approach to tunnelling and its foreseeable future. Afterwards, we will present some considerations on the three factors which tunnelling impacts: mobility, quality of life and social sustainability. As a case study, we will analyse the 2nd phase of the construction of the Marão Tunnel (TDM) -the longest ever built in the Iberian Peninsula-and describe the options made regarding each of those factors. In this case study, the options implemented made it possible to successfully execute the works. For the industry, this work is important because it describes a successful management of the aspects under analysis.

“…Also, managerial solutions have been proposed. For example, methodologies and tools have been developed to assess the environmental impacts of a tunnel [33,41] Particular, for geotechnical intensive infrastructures, like tunnels, work has also been developed on managing excavated material [39,42]. Finally, life cycle cost analysis has also been conducted on tunnels [43], which could be regarded as a financial life cycle assessment.…”

Integrating Sustainability into Major Infrastructure Projects: Four Perspectives on Sustainable Tunnel Development

et al. 2019

Although sustainability is on the agenda of many countries and agencies, it is still a great challenge to properly integrate sustainability into major infrastructure projects, like tunnels. This is remarkable, as it is commonly accepted that the construction and operation of these civil infrastructures have a heavy impact on environmental, economic and social sustainability. In academia, the foregone conclusion seems to point to a lack of vision about sustainability with respect to tunnels. This article presents an empirical study that investigates sustainability ideas amongst tunnel practitioners in the Netherlands. The case was used as a practical environment to get access to tunnel practitioners, to explicitly define the meaning of a sustainable tunnel in its development phase. Perceptions of sustainable tunnels were extracted by means of a commonly accepted research methodology called Q-methodology. By applying this method, four perspectives were obtained: perspectives with a focus on energy, resilience, social or a transitional focus. Each perspective highlights distinct focal points on how to operationalize sustainability for tunnel projects. Each perspective is also accompanied by an anti-focus; how sustainability should not be approached, sometimes contrary to other perspectives. These insights help project practitioners in creating awareness for the existence of different perspectives, and subsequently help to focus project management efforts to implement sustainability in specific projects.

Tunnel spoil recycling for concrete production at the Brenner Base tunnel in Austria

In the construction of major tunnel structures, large quantities of rock material are generated by the excavation of, for example, tunnels or caverns out of the in situ rock mass. Excavated rock material was often considered as undesired by‐product and from a legal point of view as waste in the past. Nevertheless, there is the need for construction material at the tunnel construction site directly where the rock material is generated. Broad scientific research is conducted concerning the utilization possibilities and optimization of recycling implementation. This article deals with the recycling of tunnel excavation material substituting conventional aggregate for concrete by the example of the Brenner Base Tunnel in Austria. Concrete design, material processing, and concrete production were affected by challenging geological bedrock conditions. This article presents the scientific approach, experimental setup, verification, and the realization on the construction site. The way from preliminary mixing designs to the final product is illustrated for two main rock types: calcareous schists, which successfully were recycled and processed as aggregate for shotcrete, structural and inner lining concrete; and quartz phyllite with unsuitable rock properties for concrete production due to intense foliation and mica‐rich mineral composition. The results are demonstrating the need for detailed examination of rock and concrete properties regarding the usability of tunnel excavation material.
