Abstract

The spread of techniques of industrialization in building (great load-bearing panels systems, tunnels and banches-tables with plugging panels, steel structures and mixed steel-in situ concrete) in Italy was limited to high-densely populated urban areas where important interventions of residential building were made thanks to agreement and public aid. These techniques were also used to resolve emergencies such as the necessity of re-building the building estate after the 1980 earthquake in Campania and Basilicata. This made it easier the application of the diagnostic method worked out by CIB W86 Building Pathology Board, because these interventions were realized in few big cities interested also by similar and not usual administrative procedures. Thanks to a deep analysis of 14 interventions, for an amount of about 4.500 flats, it was noticed a structural lack of quality control processes both on the project and the realization, which is typical of the administrative instruments used for these works, especially the Italian systens of awarding of contract “concessione di sola costruzione” and “appalto concorso”. This seems to be one of the main causes of quick decay and bad durability that characterizes the most part of these interventions, corroborating the negative experience of other European Countries, such as England. By a specifically technical point of view, all interventions were studied considering aging state, quality performance, functional defects or anomalies, decay situations and more frequent pathologies, trying to find out causes and possible solutions by the analysis of single cases and the diagnosis of decay process. New failure cases came out, which are worth of attention from specialists, in order to avoid their recurrence. It was also noticed that a correct project and realization can make durable and efficient as for performance also these building systems and neither prejudices and unconditioned enthusiasm are justified. In other words, it is unavoidable a deeper investigation in knowledge and data about the performance in time of this building systems.
