Abstract
Abstract. The use of digital tools and approaches related to the ICT field is now of particular importance for the knowledge and enhancement of the modern architectural heritage. The contribution intends to focus on the theme of cognitive analysis and digital documentation of some examples of public residential buildings of historical and testimonial value of the period following the second World War, in Italy, in order to define appropriate recovery strategies. Unlike buildings of historical-monumental importance, which have been the subject of studies and surveys involving the use of digital tools for several years now, little interest is still attributed to the knowledge of the building heritage of the second half of the Twentieth Century to which historical value is attributed. The interventions in the 1950s by INA Casa and U.N.R.R.A. Casas, in Italy, constitute interesting case studies that are worthy of further research and cognitive analysis based on holistic and multi-scalar approaches. In this context, the surveys and research in progress on the historical buildings of the rural village “La Martella” in Matera (1951–55) are an interesting example of experimentation using GIS-BIM digital platforms for the implementation of a multiscale knowledge methodology (from the territorial scale, to urban blocks to individual buildings) that provides for the structuring and implementation of an integrated information database (Common Data Environment) aimed at defining recovery strategies for the protection and enhancement of the historical buildings of the village, through the concept of interoperability for the systematization of archive sources and data obtained through surveys on the existing situation.

1.1 ICT digital systems for the knowledge and management of the modern architectural heritageThe proposed contribution is related to the knowledge, recovery and enhancement of the modern architectural heritage, in this case related to social housing, through the adoption of approaches, methodologies and tools related to the ICT (Information and Communications Technology) field
The joint use of both technologies is recommended for the cognitive analysis as well as for the survey of the existing heritage and, through the extrapolation of quanti-qualitative data, for the development of strategies for the recovery and management of this heritage
Summary
1.1 ICT digital systems for the knowledge and management of the modern architectural heritage. While the GIS systems are created and evolve mainly via use of 2D digital models for the modeling of the existing heritage at a territorial scale and have been in circulation for almost thirty years, BIM on the other hand, is a more recent technology and is mainly used in the field of new constructions, on an architectural and detail scale, through the use of 3D-semantic models referred to individual buildings or building complexes Another important aspect that highlights the difference between these two information systems is the different degree of accuracy in the management and implementation of non-geometrical attributes on the one hand, and the level of graphic detail achievable in relation to geometric entities on the other; while GIS are based mainly on a high capacity of implementation and probing of spatial data and related attributes, to the detriment of a more limited geometric processing capacity, BIM technologies, on the contrary, allow for the achievement of a high geometric detail (through the concept of Level Of Development), to the detriment of a greater deficiency in the management and implementation of non-constructive attributes (Saygi et al, 2013; Volk et al, 2014; Spallone et al, 2016; Tobiáš, 2016). The integration between the two software environments is still under development, especially with regards the transfer of information between the two systems (Tobiáš, 2016; Barazzetti, Banfi, 2017; Ma, Ren, 2017; Matrone et al, 2019)
