051524 - ARCHITECTURAL PRESERVATION STUDIO
The aim of the Studio is to provide students with operational and conceptual tools necessary to elaborate a preservation project, facing methodological and theoretical aspects in a multidisciplinary approach. The teaching will be conducted on the base of an in situ surveying exercise on the case study of which will be recognised its proper characters, its evolution, and identified the diagnosis of the degradation of structures and materials.
With particular care will be analysed the constructive features of the historical building, by recognising construction techniques, structural elements, materials and their physical and mechanical characteristics, behaviour to climatic and microclimate conditions, to highlight their peculiarities and vulnerabilities.
Following the analytical phase, that is retained unmissable to make conscious design decisions, the conservation design is developed, taking into account new forms of compatible use, with the necessary adjustments to mutated needs.

The course intends to provide specifications for preservation and compatible reuse for historic buildings.
The first part of the course will be covered by a quick summary of the methodology for the preservation of historic buildings with theoretical lessons alternated with practical activities in the field of design. Quizzes about the acquisition of theoretical knowledge are planned. The second part will be entirely devoted to exercise (preservation and reuse project), group revisions and individual study. Groups will be constituted by no more than 3 students. The Architectural Preservation course wishes to teach the way of a macroscopic survey of materials, technologies, decay and instabilities problems (causes and effects) and furthermore, the main stages of analysis and diagnostic for a scientific approach to preservation. Finally, it teaches how to solve problems with a conservative, minimum and sustainable approach intervention.
The Architectural Preservation part is integrated with the Advanced Survey Techniques course with the main aim of studying and practising the architectural shape-knowledge processes as the basis for Cultural Heritage understanding. Advanced Survey techniques parts course is mainly focused on techniques and methodologies for 3D survey acquisition and 2D metric data extraction.
A first phase of the work will be the study of the area both from a geometric point of view (Architectural Survey) as well as materials, technologies, and conservation one. The activities of the laboratory will be based around a real case of study. It will be communicated by teachers at the beginning of the course.
Students will have to produce a general overview plan of the site and a detailed representation of the historic building. After that, students must provide the material and deterioration maps, and a project to outline the preservation interventions. Everything should be done on the scale 1:50 or 1:20 depending on the characteristic of the building.
Subsequently, the exercise will focus on a reuse project, starting from the masterplan scale (1:500) up to the representation scale of 1: 100 - 1:20 and any details according to teacher’s requests.
A detailed report will describe step by step the whole work done both for the survey and preservation part.
In the Advanced Survey techniques module, two very modern survey methods will be presented and practically experienced during the course to produce accurate 2D drawings of a very complex environment (and eventually 3D modelling). Terrestrial laser scanner will be presented as the main method for an accurate real-time 3D survey of a large and complex environment. The photogrammetric methods will be presented as the newest methods for 3D digitalization and as the mandatory process for orthophoto generation as support of conservation design. Some notes of the total station survey will also be illustrated as classical methods to support advanced 3D measurement.
The 2D/3D data managing will be run in the CAD environment, and the representation will be aimed at raster-vector integration. Other ICT solution to manage, process and visualize the survey data will be introduced during the course. Different software tools will be used to process and manage numerical survey data. The use of windows environment is highly recommended and for some activity mandatory.
An additional bibliography will be provided during the course about the specific covered topics.
Passing the exam will attest to the acquired ability to apply appropriate techniques and methodologies on historic buildings and landscape, operating at different scales with the autonomy of judgment and demonstrating, during the milestones and the final exam, learning and communication skills.
Lectures of Architectural Preservation part will be about the preservation principles and the working methodology applied to the real examples. The main steps of the process will be the initial knowledge of the working area, the progressive deepening of materials and technologies characteristics, material and structures decay problems (causes and effects), and finally the preservation project for a compatible reuse design.
During the first part of the Advanced Survey Techniques, theoretic notes about laser scanner, photogrammetric acquisition and data analysis will be provided. The second part will be dedicated to data elaborations, drawings and model creation useful for the preservation part.
Knowledge about history of restoration/preservation, historical buildings materials and technologies are considered essential for the course. The teacher will share papers and booklet to permit students that have a lack of knowledge in the above topics, to reach the necessary expertise.
Knowledge relating the basic principles of direct/geometric survey and superficial notions about photography would be preferable.
Active attending of lectures and revisions, not just the review of the own group, is mandatory for everyone. Students attendance will be evaluated in the final mark.
Modalità di valutazione
Verification in progress
At the end of each stage of lectures of Architectural Preservation, the teacher will provide quizzes to verify the students learning and the understanding of the topics for both modules. These tests will not be evaluated and considered in the final mark. The themes touched inside theses quizzes will be on the content of lectures and the assigned bibliography and will be useful to train students to the Test that will be valuated ad part of the final mark.
For the preservation part, two milestones with evaluation will be organized. One will take place at the end of the 1st part of the course (General overview of the site, material and technologies survey, deterioration and instabilities survey) and the second at the end of the 2nd part of the course (Preservation design, Masterplan, Reuse project).
For the Advanced Survey Techniques part, one evaluation step is planned immediately after the initial theoretical part.
During the two Preservation module milestones, each group must submit the requested steps of work, and the teacher will evaluate them. The final submission of the whole correct work by every group will close the course.
The average of all the marks (Test + 1st Milestone + 2nd Milestone + Final submission of the work) will constitute the final grade for admission to the exam.
The marks could be diversified within the group components according to the quality of the individual work and a different score related to the milestone tests.
The final verification consists in delivering, discussion and judgement of the last, complete and correct whole work. In particular, the final evaluation will include:
The evaluation of all assigned descriptive technical reports
The evaluation of the graphic work elaborations that will consist of the group evaluation of the graphic-design activities.
For the survey module, the final examination will consist of the presentation of the survey job (drawing, and eventually 3D modelling). It will be evaluated: i) the ability to manage and extract data for 3D point cloud data, ii) the quality of the final representation and iii) the use of the survey products for the preservation activities. This group job evaluation and the individual midterm test will constitute the final, personal evaluation of the survey part.
Different weight in the percentage about the two course (6cfu-4cfu) will be considered for the final mark.
For both parts, both native working files (DWGs…) and final pdf files must be delivered no less than 4 days before the exam. The printed version must be presented during the final discussion.
The order, the punctuality, the completeness of the final files and of the printed version will be object of judgment by the professors.
