The experience described in this paper concerns a research activity carried out by a multidisciplinary team. The research is aimed to increase the in-depth knowledge of the castle of Fossa (L'Aquila), part of a small fortified medieval village, seriously damaged by the earthquake in 2009, and currently unusable due to partial collapses of some vertical structures, small portions of buildings and roofs. The investigative path planned by the team, composed of archaeologists, architects and engineers, started from the architectural survey (direct and indirect) of the artefact, from the collection and cataloguing of the published and archive documents, to arrive at an archaeological analysis of the structure and the creation of a parametric digital model of the object of the study with multiple levels of information. The aim of the research is the consideration of the asset in its entirety, that will be interpreted in its restoration project, in order to restore the correct and original architectural interpretations of its constructive style. The project has also presented the opportunity to experiment, in the form of a research laboratory, how well coordinated multidisciplinary contributions can achieve objectives of protection, conservation and use of the asset. In this regard, the HBIM model has constituted a tool for the convergence of the objectives, skills and the different viewpoints of the multidisciplinary team.

Road networks are disseminated of bridge structures whose typology reflects the time of design and construction of the transportation infrastructure and its relevance in the reference geographical area. Among others, masonry bridges are still widely operational, especially in those regions affected by a limited urbanization and a very high landscape value. As a consequence, the maintenance and the reliability of existing structures is a key issue for owners and managers of road and railway infrastructures. This circumstance leads to the development of an integrated approach able to cover the needs of knowledge of the technological and structural features of the bridge along with its history and current conditions. The main contribution of the study lies in the implementation of such an interdisciplinary approach through the application of archaeological stratigraphic method and 3D data management to historical masonry bridges. The survey and inspection protocol, whose first results are here presented, aims to improve the knowledge of the assets, and facilitate the visual inspection. The results refer to a road infrastructure located along the Aterno River in the surroundings of L’Aquila (Central Italy) and point out promising perspectives in terms of feasibility and scalability of the approach to large stocks of assets.

Keywords: 3D GIS, Documentation of Cultural Heritage, Archaeological Heritage, Digital Photogrammetry, Archaeological Survey, 3d modelling of archeological data This paper illustrates the results of an experimentation carried out by a multi-disciplinary research group made up of researchers from ITC-CNR of L'Aquila and of archaeologists of the University of L'Aquila. The research project carried out by the team is based on the analysis of the archaeological heritage (in particular, the documentation of some burials found in the medieval site of Amiternum, near L'Aquila). This starts from methods based on digital photogrammetric restitution, based on Structure from Motion (SfM) algorithms, and the generation of photorealistic textures in order to manage, in a 3D GIS environment, complex archaeological and anthropological data. The choice of technology to use is often determined by the specific needs of the survey, the purpose of the project, the budget and experience of the researchers, and the geometric characteristics of the assets, rather than the precision to be achieved. For the survey of the archaeological excavation of the medieval site of Amiternum, it was decided to use digital photogrammetry given that the objective was to document, with a rapid survey compatible with the times of an archaeological excavation the phases of image acquisition, processing and post processing of the site model. Furthermore, thanks to the integration of two technologies, digital photogrammetry and GIS, and the undisputed improvement in the management of 3D data by the GIS, three-dimensionality, in archeology in general, has become an indispensable component for site interpretation and for the documentation of the data.
