The intervention mainly involves the construction of a road bypass at the Rumerlo finish area, to allow for its modification according to the requirements of the FIS (International Ski Federation). The BYPASS consists of the construction of a road section with a total length of about 640m and a platform width of 6.0m. The infrastructure design involved numerous complexities, due to the typically mountainous topographic conditions with steeply sloping and partly unstable terrains. To ensure the stability of the slopes in the excavated sections, given the poor bearing capacities of the encountered soils, the design of significant support structures such as reinforced concrete retaining walls, pile foundations, and an anchored micropile berlin wall was necessary. Upstream of the berlin wall, an additional support for the slope located between the bypass and the “Muro de Ra Cioure” ski slope was also designed, made with a green-faced nailed wall.
