The didactic activity of the Restoration course within the Atelier Compatibility and sustainability of architectural restoration D aims to provide the methodological and operative tools necessary for a correct approach to the restoration project, recovery, refunctionalization and reuse of buildings and urban areas of particular historical-cultural interest, with specific reference to the architecture of the Twentieth century so as to provide students with an independent critical competence for their protection and conservation Advanced tools for architectural modelling module (Geomatics) addresses the set of knowledge and practical skills necessary to understand and document an architecture being the material evidence of a cultural value. The relation between Restoration and Geomatics is mutual in the sense they both influence the choices and actions related to the object integrity and the use fitting it. The first usually direct the data acquisition, usually determining the expected outcomes, including the LoD (Level of Detail) and the best kind of representation suited for the values we want to preserve. At the same time without a clear and complete graphical documentation of the object is almost impossible to evaluate the state of preservation and thus the results of the survey may also influence the Restoration choices and actions. The Geomatics module therefore will deal with all the aspects necessary for a comprehensive understanding and description about the geometry of the architecture being the case study for the development of the project, from the data acquisition to the graphic rendering.

Students will have to demonstrate their ability to autonomously express an ability to judge restoration as a cultural and scientific tool aimed at preserving and transmitting historical-architectural values, starting from the methodology of historical research of investigation and relief, as a fundamental moment of the knowledge process of the monument, to the intervention techniques, to be analysed and evaluated in different conditions according to the effectiveness, compatibility and reversibility of the intervention with respect to the object and the urban context. The goal of the Geomatics module is for the students to master the surveying, 3D modelling and drawing techniques for the architectural heritage documentation. At the end of the course students are expected to be able to plan a survey targeted to a specific architectural heritage and deliver the graphics suited for best representing the geometry of the object and its cultural values. Furthermore students will be asked to analyse the object at different scales, from the smaller ones suited to relate the object with the context (i.e. the village or the district), to the bigger scales useful to detail the object features and state of preservation. Usually required deliverables include integrated vector and raster 2D representation, such as elevations, floor plans and textured photorealistic 3D models.

Basic skills in the 2D drawing and 3D modelling are required in order to shape the unstructured data resulting from the survey into a well defined set of deliverables. Therefore a general knowledge of CAD and 3D modelling software is essential to comply to the course tasks. For these purposes students are free to choose the software they are more acquainted with.

Restoration Contemporary debate on the reuse and restoration of modern architectural heritage between innovation, conservation and safety in Italy and Europe. The "cultural assets" subject to protection. Architectural restoration, urban restoration, landscape restoration. Legislative foundations for the protection of the heritage of the twentieth century The Code of Cultural Heritage (Legislative Decree 42/2004 and subsequent amendments), the Procurement Code and other regulatory instruments. The Ministry of Cultural Heritage and Activities and Tourism, the Superintendencies and the protection bodies. What is a protective measure. The restoration project on protected assets and public assets at different project scales. Architectural restoration project Understanding of the building organization at all scales, starting from the urban one and ending with the detailed one, as well as in the broader landscape of settlement planning. Critical analysis of the constructive, functional, typological and formal aspects necessary for a correct preparation of the restoration project; materials and conservation issues related to material and functional obsolescence. Identification of the causes of degradation and of the environmental interactions that affect the building. Conservation and restoration techniques of 20th century materials, requalification and energy efficiency. Enhancement project Intended as the broadest planning of actions on a landscape and urban scale, not only of recovery, reuse and restoration but of integrated conservation that looks at the building as part of a system of assets at the center of social, economic and cultural dynamics. Geomatics Main topics of the Geomatics module include the methods for the acquisition and management of 3D metric information which is integral to the Restoration project. Course topics embrace topography, photogrammetry and cartography. While most of the techniques used for the data acquisition and processing are automated, a deep knowledge of the methods is necessary in order to extract the shape of the objects out from the raw data and represent it on a suitable medium . Surveying methods and techniques will be used are: • Total Station (TS), Global Navigation Satellite Systems (GNSS), for the survey control and the referencing of the detail surveys; • Light Detection And Ranging (LiDAR), also known as laser scanning, for the detail survey; • Digital photogrammetry and Structure from Motion (SfM) for the detail survey; • Geographical Information Systems (GIS) for maps creation and mash-up. Survey data processing will involve the editing of point clouds from LiDAR and photogrammetric sources and the extraction of highly detailed graphics (1:50) such as: • vectorized floor plans from point cloud sections; • raster ortho-photos • textured mesh with bitmaps from survey photos More specific specific software will be used to manipulate point clouds such as CloudCompare, MeshLab and PointCAB. GIS analyses will be performed at urban scales (1:1000 – 1: 5000) focused on the relation between the object and their surroundings. Web Map Service (WMS) and Web Feature Service (WFS) will be used to retrieve the base and thematic maps showing the main relevant features such as buildings, transportation, hydrography, etc. The history of the building and its context will be analysed by geo-referencing historical maps on the base maps. GIS data will be handled with specific software such as QGIS and ArcGIS.

About half of the course credits will be dedicated to lectures on the above mentioned topics and field activities for data acquisition (if possible). The remaining part will be dedicated to the data processing, drawing and 3D modelling with the assistance of the teaching team. As we pointed out theoretical the knowledge transfer through lectures and collective exercises will be integrated with the work of the students on the graphics and more generally the development of the project together with its evaluation from the teaching team. Therefore there will be progress checks during the course in order for the students to be easier to follow the path and do not miss any important notion and task.

Students will be provided with lecture notes covering all aspects of the course, including tutorials on the tasks to be performed.
