Abstract
Reinforced concrete was one of the most used materials in construction in the twentieth century. Always considered a material with exceptional characteristics in terms of durability and resistance, it has instead highlighted significant critical issues over the last 50 years. Concrete’s weak points are vulnerability to the actions of chemical agents and degradation due to design and construction errors; for this reason, in recent decades, restoration interventions, recovery and re-functionalization of these artifacts have steadily increased. These interventions are useful for safeguarding the life of the building only if accompanied by continuous maintenance. Knowing the building in all its parts, with the greatest possible precision, can increase the effectiveness of maintenance and recovery interventions. In recent years, BIM modelling is taking on a pivotal role in the design and management of reinforced concrete buildings. In this paper, an example of “reverse engineering" is presented, which allowed the construction of the HBIM model of an existing building via: (i) the collection of the available design materials (e.g. design tables), (ii) a parametric survey on site, (iii) the modelling of the building using the acquired knowledge. This approach can be considered as a turning point in the management of reinforced concrete buildings, since it simplifies and organizes all the information required to maintain the existing built heritage, optimizing the available resources.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
