The multidisciplinary Atelier addresses the integration of some disciplines that contribute to the realization of a sustainable, aimed-at-re-functioning, Restoration Project, with a particular focus on the innovative techniques for survey and the communication of the project. The disciplines of Restoration, Survey and Representation (Drawing and Geomatics) are coordinated within a design exercise that students are asked to develop, at different scales of study, facing the relevant themes related to: - preservation, - structural rehabilitation, - compliance with codes, - design of new functions - cultural, economic and environmental sustainability. The Restoration unit aims at contributing to the formation of the student’s design experience in the field of built heritage. The general framework within which the design activity will take place comprises, on the one hand, the analysis of the evolution of the general built context, which the building selected as a case study belongs to, and on the other hand, the direct knowledge of the building itself, according to the restoration principles and methods. Such a knowledge is based on the historical research, the survey of constructional techniques and structural apparatuses, the analysis of decay and distress phenomena of the building. On this background, the project can be developed, continuously verifying the principles of (environmental, economic, cultural, social) compatibility and sustainability -moreover trying to share (whenever possible) the enhancement process with local authorities – and constantly relating to the other modules. The main objective of the New Technologies for Survey and Drawing unit is to provide students with the methods for evaluating and selecting the survey and representation techniques which are the most suitable for the development of the restoration design, offering theoretical knowledge and operational tools to detect and represent architecture in its various components. Firstly advance techniques concerning 3D survey will be analyzed that will be based on digital photogrammetry and LiDAr acquisition devices. Moreover different representation techniques will be experimented, in particular digital 3D modeling techniques, considering them not only as fundamental means to describe and comprehend reality, but also as key communication systems for educating to the view of the built environment, at different scales, and to its metric control. The teaching activity is aimed at providing theoretical and practical knowledge of the most proper and advanced drawing softwares for the representation of reality, describing their correct and conscious use.

The expected learning objectives essentially concern the following topics: - Theories and techniques for the restoration design of architectural heritage; - Fundamentals and basic theoretical principles of the 3D survey methods (digital photogrammetry and LiDAR); - Survey theories and techniques for managing the design process of restoration; - Fundamentals and theoretical principles of Cartography (projection systems and reference systems, elements of digital mapping); - Principles of Geomatics; - fundamentals of architectural 3D modeling. The students will be able to apply their knowledge for the achievement of the following objectives: - Recognizing the formal, structural and material features of historical architecture; - Identifying meanings and uses of architectural heritage, in both tangible and intangible aspects; - Verifying the compatibility of re-functioning choices in the restoration project; - Checking autonomously the sustainability of the conservation project; - Drawing properly the restoration project (virtual image and real image); - Exploiting properly 2D and 3D representation systems; - Using representation methods and scales suited to the different needs of the project; - Managing IT protocols and representation systems for the collection, organization and processing of information as a support for knowledge and sustainable management of architectural and environmental heritage; - Using Geomatics as a methodology to acquire an ever wider and more accurate knowledge of the existing buildings, optimizing survey and monitoring techniques.

Preliminary to the Atelier are considered the skills and abilities acquired in the three-years degree course (theory and history of restoration, drawing and survey, structural and technological disciplines, architectural composition and history of architecture).

So far the case study of the Atelier is not yet defined. We can only specify the essential features it has to be endowed with in order to allow students to perform a fruitful exercise: simple accessibility and plain relation with the context (to ease survey activity, also by new technologies), relatively small dimensions and clear constructional apparatuses (to make direct survey possible), availability of bibliographic and archive sources (to overcome, or at least reduce, difficulties unavoidably experienced by foreign students). Therefore, the case study will be a building suitable to being studied at different scales, from the urban one – that involves its relationship with the surrounding historical fabric - to that of the building itself - which, in turn, can be examined by means of both direct (on site) and indirect (on bibliographic and archive sources, including historical Treatises) analyses. The lectures of the Restoration unit (6 CFU) will deal with the general features of historical masonry constructions, the main forms and processes of decay and distress they can undergo, the interventions that can be carried out on them in the framework of a consistent methodological approach to restoration. The lectures of the New Technologies for Survey and Drawing unit will be focused on the available new methods and technology for 3D survey and representation. The part will be divided in several steps: - theoretical lectures for understanding the methods and technology used for 3D survey and representation; - on the field data acquisition (New Technologies for Survey) using LiDAR instruments, topographic surveys and photogrammetric acquistition withh the use of Drone as well in order to document the area at an urban and architectural scale; - data processing using commercial and open source software (photogrammetric Structure from motion techniques, topographic and LiDAR ) in order to obtain 3D point Clouds, 3D models, orthophotos and Digital Surface Model (DSM). - 2D drawing extraction (Drawing) starting from the achieved 3D point clouds - parametric 3D model realization with the aim of HBIM realization.

The Atelier comprises lectures on the above mentioned topics and an exercise on the study case of the Caserma Galliano. The teaching methods include frontal, mono and multi-disciplinary, lectures focused on the real experience of the restoration project. The examination of the study case assigned to small groups of students (no more than three students) will allow dealing with the methods of intervention described in the theoretical lectures, sharing and deepening them in collective discussions. On-field surveys are provided for in dates that will be communicated at the beginning of the Atelier.

References will be reported during the individual learning activities, in relation to the addressed issues. The basic material for the exercise will be constantly updated on the website of the course, where students will also find excerpts of the lectures.

Modalità di esame: Prova orale obbligatoria; Elaborato progettuale in gruppo;

The attendance of the Atelier is essential to develop positively the planned activities. The attained knowledge will be checked by discussing the exercise requested by the professors and through an oral examination concerning theoretical and applied aspects of the different disciplines of the Atelier. In-depth studies on monographic issues, or specific reports on technical topics, could be required, always aimed at preparing the project. The assessment of the performed work and the evaluation of the results, will take into account not only the degree of learning and maturation of the students, but also the ability to properly present ideas and proposals and promote the comprehension and participation of future partners to the proposed project. The final evaluation will take into account the intermediate assessments and the total amount of work, and will be based on the final discussion of the exercise (whose weight is 70% of the final mark) and the acquisition by each individual student of specific abilities regarding the Atelier topics as well as its participation in every phase (the remaining 30%). The exam may be passed only with a positive judgement in both disciplines of the Atelier.

The attendance of the Atelier is essential for positively developing the planned activities. The final exam will consist of: (i) a discussion of the design exercise - for which each student will have to answer individually and his/her own contribution will be evaluated -; (ii) an oral examination of the individual knowledge of the basic notions of the course (by answering questions on the theoretical-part of each of the modules). The evaluation will take into account the students' degree of learning, their ability to correlate different interdisciplinary contents, the ability to correctly present the achieved results using a consistent technical-scientific language. In the final evaluation - which will also take into account the intermediate evaluations (the exercises revised by teachers and the intermediate collective revision) - the design exercise will weigh 70% and the oral examination the remaining 30%. The exam will be passed only with a positive judgement in both disciplines of the Atelier. The final mark will be unique and will represent the the average of the evaluations in individual modules.
