BBT Lot Mules 2–3: Sustainability and Long-Life Performance

Sustainability aims to maximize circular economy and durability, by reducing construction costs and maintenance needs and increasing the works lifetime. Brenner Base Tunnel (BBT) Lot Mules 2–3 is conceived, designed, and built with this vision, focusing sustainability and durability as prevalent goals, targeting a 200 years’ lifetime. Specifically, durability is the result of appropriate choices of techniques and materials in planning and design phases, for instance: exposure assessment, attention to construction details and to the use of durable construction materials in relation to the actual attacks. Also, the use of construction, demolition, and excavation waste (CDW) is beneficial, if planned and managed with appropriate characterization systems and production processes.
