Temporary systems after the earthquake in L’Aquila

After an earthquake, temporary structures play a key role in the immediate emergency and during the reconstruction. In the territory of L’Aquila, after the earthquake of the 6th April 2009, tents were used in the first emergency to provide immediate shelter to the population and prefabricated structures have been used later to accommodate the population during the longest stage of the reconstruction. But there is another type of temporariness too, linked to the securing of the damaged buildings and aimed to preserve the historical and artistic value and ensure the safety of road and workers during the reconstruction period. The secure systems use temporary devices, consisting mainly of tubular scaffoldings, multi-directional systems, systems in wood, systems with metal profiles and steel cables, polyester clamps. These systems are used interchangeably according to the function they perform, flexibility, time and cost of installation. During the reconstruction phase safety systems are disassembled, progressively generating an enormous amount of waste materials. For these materials it has not been planned a second lifecycle and disposal has a high environmental impact. It is proposed the reuse of these waste materials at zero distance. The purpose is to obtain environmental, logistic and economic advantages. Reuse provides a function change under the temporary, from safety systems to building systems, aimed to the construction of temporary structures, which, in the reconstruction phase, simplify site organization and, in the post-reconstruction phase, restructure public and private spaces.
