Application of a digital framework towards the comprehension and restoration of the thin marble envelope of the ‘Casa delle Armi’ built cultural heritage

"Casa delle Armi” by Luigi Moretti (1934-37), is the first modern building in Rome cladded in marble; its cladding was a reference for the architectural production in Italy, before the Second World War. The envelope is nowadays in need of urgent restoration. However, the strategy of intervention is not yet clear, due to technical problems and conflicting requirements. This manuscript develops the so-called "Informative Abacus" to propose a theoretical framework towards the restoration challenge, by exploiting the digital possibilities related to Building Information Modelling (BIM), towards a comprehension of the history of each slab composing the envelope. The framework is the basis for comprehensive analyses aimed at restoration: simultaneous costs/benefits, construction and design evaluations could be conducted to guide the strategy of intervention. The aim is also to allow for the enjoyment of the asset for tourism, towards sharing of such an important historical heritage, both digitally and in-person.
