SURVEY METHODOLOGIES AND 3D MODELLING FOR CONSERVATION OF HISTORICAL MASONRY BRIDGES

Abstract. The safeguarding and conservation of built heritage and historical infrastructures represent complex tasks, especially for administrations and stakeholders operating on peculiar and unique territories with specific cultural, social, and economic problems, such as the historical centres of Inner Areas. However, heritage conservation and management processes can be facilitated by multidisciplinary knowledge methodologies based on solutions offered by digital technologies in the field of documentation. This paper aims at defining novel procedures able to enhance available tools towards a real heritage e-government and e-conservation. The integration of laser scanning and photogrammetric survey-based techniques, as well as on the data of the multidisciplinary analysis available in a virtual environment, the implementation of the parametric model of a historical infrastructure has been investigated for assessing the issues related to the preservation and maintenance of these infrastructures, also in relation to their safety and enhancement. The application to a real case study pointed out the opportunities offered by new technologies in the integration of data coming from different research fields, and the reliability of parametric models in visual inspections and, as a consequence, in the planning of interventions of safeguard and conservation as well as those of valorisation of the historical heritage.
