The purpose of the Studio is to understand and know the phases necessary for the design of the existing building conservation project, the principles and best practices that are indispensable in the historical construction and essential for the graduation of architecture graduates. In addition to the creation of thematic maps concerning historical constructive techniques, forms of degradation or manifest or latent disruption with the study of the causes - for which the development of the survey is necessary - analyzes useful techniques for the diachronic reading of buildings, transferring the awareness of the role of the historical survey within the conservation process. Following the indispensable analysis phase to make informed and consistent choices, the student develops the artifacts conservation project by analyzing - among others - the requirements of efficacy, compatibility, durability, reversibility ... and sets the project for a possible new compatibility, considering the necessary adjustments to changing needs. Attention is also drawn to the drafting of the technical documents accompanying it, to the legislative framework within which it is built and to the connection between theoretical aspects and practical activity.
The purpose of the Laboratory is to make the student aware of the features and problems that the intervention on the built presents, in relation to its historical and cultural significance and at the same time as a resource for contemporary use. Therefore, besides ex cathedra lessons, he/she expects practical lessons on the concrete case studies to be "taught by doing" with the aim of implementing critical skills and operational tools that stimulate the care process to the built environment.

The purpose of the Studio is to understand and know the phases necessary for the design criteria addressed to existing buildings. The conservation project, applied to historical buildings, is developed through theoretical principles and best practices that are essential for the definition of the interventions on the materials composing the building and the strategical solutions concerning its final destination, use and further valorization.
The Studio is organized by two modules: Advanced Survey and Preservation. The professors will offer a theoretical background of the contents of their disciplines and will propose a driven and integrated activity on an assigned historical building for the on-site workshop experience. The on-site activity is organized by dividing the class into workgroups: the number of components is defined according to the number of students attending the Laboratory. Both courses propose a deep integration among the arguments, considering the conservation field as a multidisciplinary activity, where geometrical issues are strictly connected to a wider comprehension of the material and technological components of the building, expression of a specific constructive culture, representing the historical characteristics of the chosen cultural contest.
The geometrical survey of historic building is a fundamental aspect for further analysis on the building as well as restoration/conservation activity. For this reason, the course cover both traditional and innovative survey techniques. In particular the following techniques will be presented:
·Total Station survey; and
·Laser scanning survey.
The theoretical and practical aspects of these techniques are covered during the course along with their application concerning the chosen case study. In particular, their peculiarities will be presented and discussed as well as their integration. Particular attention will be given in order to determine the most appropriate technique according to the defined aims in terms of final products, their accuracy, precision and scale. Particular attention will be paid in describing the contribution of each technique for the purposes of architectural survey.
The geometrical survey is the starting point for a proper description of the building by means of the technical architectural language (i.e., plans, sections, elevations, etc.). For this reason, specific attention will be paid in presenting the requirement of a technical drawing making reference to national and international standards (e.g., ISO).
The on-filed activity is aimed at allowing students to get in touch directly with the content of theoretical classes. During the workshop activities students will practice with both standard and innovative survey methods presented during the lectures. Stating from this survey activities, students will turn their measurements into products commonly used in the architecture, building and construction domain (i.e., plans, sections, elevations, etc.) by making reference to good practice and standards.
The preservation course, on the basis of the survey activity, introduces a knowledge path developed among different thematic maps useful for providing a complete interpretation on different aspects concerning the building: historical evolution, constructive logic, decay problems, possible solutions.
The aim of the Studio is to reach a final awareness of the features and problems characterizing the interventions on the built heritage. By analyzing the building properties, recognizing its constructive features, assessing its knowledge in depth by using codified methodologies (standardized by legislative documents and practical activities) proposed during the course, the students will provide a conservation design composed by the intervention strategy for preserving the material integrity of the historical building and the adaptive reuse proposed for matching the necessary adjustments requested to the changing needs.
Signifiant topics developed during the Studio:
- Direct survey.
- Topographic survey.
- 3D Laser Scanner Survey: data recording and data elaboration.
- Digital image rectification.
- Historical analysis.
- Building techniques.
- Materials mapping.
- Materials decays.
Modalità di valutazione
The exam consists in developing different thematic tables and some technical reports. The material is evaluated in specific deliveries arranged during the studio for a first submission followed by the evaluation of the teachers. During the ordinary exam dates, the students will have an oral exam concerning the on-site workshop and the theoretical background provided during the lessons.
The final exam grade will be determined by the outcome of the exam and the overall assessment of the student's work in the studio.
