Abstract

The re-qualification of modern architecture buildings, often embedded into consolidated historical areas of absolute value, has become a priority in our cities. Together with the spatial, architectural, technological and performance redevelopment, there is a need/urgency for seismic structural adjustment. These buildings, that were pioneering in their conception, suffer from their own experi-mental genesis which requires regulatory and performance adjustment even in cases of excellence. More in general, actions to adapt these building to contemporary uses are more than urgently needed. Through the case study of the redevelopment project (carried out with the expert advice of DICAAR) of the former University paediatric clinics of Cagliari, the paper illustrates a methodology of integrated intervention which aims to rethinking spaces, together with a hypothesis of use-programme which involves heavier structural modifications, with consequent anti-seismic adjustment. In the absence of archive documents, a thorough knowledge process was conducted involving non-destructive techniques and load tests. This allowed the reconstruction of the material-structural characterisation of the building and its technical and constructive dimension, that were pivotal for the full-scale intervention.
