Conoscenza e tutela degli edifici in c.a. dei primi del Novecento come frontiera del restauro

In Italy the necessity to safeguard reinforced concrete buildings of the Twentieth century had emerged and was stabilized progressively during the second half of the last century. Since that moment numerous studies were devoted for this theme, conventions had put emphasis on the materials, technique author and other aspects. The Superintendence launched knowledge campaigns of the territory and census by inquiring into parameters of selection to adopt in order to place a restriction and then declaration of the cultural interest, according to the Code of Cultural Heritage. Therefore the historical and artistic value from time to time was recognised as well as the social meaning of the work, the correlation with the background or the innovation from the point of view of materials and the construction principles. Despite this fact, the two illustrated examples allow to highlight that reinforced concrete buildings are unrecognised as a part of the heritage to protect. It is significant the case of the ex-Multiplex Odeon in Genoa, that has not been substracted from speculative logics despite having all the features mentioned in order to be selected as part of the heritage of the Twenties of the Twentieth century to defend. The second example about ex vegetable market in Genoa, concerned the practice to safeguard some part of the buildings or complex, that seem to be selectable as exemplifying of standardized and repeatable works.
