75458 - MATERIALS AND TECHNOLOGIES FOR HISTORIC BUILDINGS M

Conoscenze e abilità da conseguire

At the end of the class, student has knowledge of the evolution of both the historic materials and construction techniques and the repair methods, especially focusing on stone, wood and masonry. In particular, at the end of the course he/she is able to specify a set of criteria useful to ensure that the materials selected for conservation and rehabilitation are best suited to the needs of each building in terms of safety, efficiency, compatibility and cost effectiveness, as a palette of variables that the design must manage simultaneously.

Metodi didattici

The course content will be entirely covered by lectures.

The course is divided into two modules

- module 1 Prof. Marco Bragadin

- module 2 Prof Francesca Bond

 The two modules will be held simultaneously, i.e. module n. 1 will address theory and module n. 2 will address practice exercises and homework. 

Mandatory homework / project work will deepen course topics, students can have support from the computer laboratory of the faculty. In-class practical works will be evaluated in the final exam. Attendance in practical classes is recommended.

Modalità di verifica e valutazione dell'apprendimento

Achievements will be assessed by the means of a final exam. This is based on an analytical assessment of the "expected learning outcomes" described above. Both modules will be tested in the final exam. 

In order to properly assess such achievement the examination is composed of different sessions: written session, which consist of a test composed of questions; to be eligible to take the oral exam the student must score in the written test a minimum total of 18 points with a maximum of 30.

The oral session, consists of: a review of the homework and of the in-class exercises, and a review of the written output, in which examiners inform the student on grading criteria, and receive any student appeal supported by appropriate explanations; and a technical conversation.

In the final exam written and oral examinations are mandatory. Homework and in-class exercises will be evaluated and discussed in final exam. Homework must be completed and passed prior the oral exam.

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents.

Strumenti a supporto della didattica

The teaching tools are projector and PC.
