The Use of Natural Earth as Concret Slab: The Dome for the Auditorium of Sant Julià de Ramis Fortress (Girona)
This project provides for the restoration of Sant Julià's fortress complex, built at the end of the 19th century . The restoration is planned to create a facility to host a contemporary arts center with complementary services: workshops for artists, an auditorium for 450 people and a hotel-restaurant. The fortress is formed by a complex of independent structures, built with vaults and stone walls of considerable thickness, the majority being semi buried and connected by 1500 m of tunnels and galleries dug into the mountain. The lower part of the complex hosts the museum, while the hotel is located at the higher level, in the former "stronghold", the space where explosives were stored. In front of the main entrance, an oval-shaped auditorium is planned, with a height of 7.5 m and a vault made of concrete.All the new buildings are mostly made of reinforced concrete, with glass and corten steel being prominent, to avoid mimicry of the existing structures and to work with the old and the new as two joined parts of a whole set.The planned dome is an oval space of 34 x 24 m, covering a surface area of 524 m2, built underground to comply with current urban planning legislation. For the construction of the new dome, a formwork system with natural earth from the site has been used. This article analyzes different issues related to the concept of adaptive architecture, taking as an example the construction system used and the different phases of the process, planned and directed by the authors of this article.
