The re-qualification project aims at the seismic improvement of the "Enrico Fermi" Primary School in Bettola, that at the outcome of the vulnerability seismic assessment has detected a resistant capacity against a possible seismic action equal toabout 60% compared to the project acceleration for a new building. The intervention in question involves the construction of 2 metal carpentry structures external to the building, characterized by autonomous "caisson" foundations and connected to the building existing through the use of a series of metal tie rods and a stiffening slab placed on the attic floor.
