Type of delivery of the course

The course involves the analysis and in-depth study from a structural point of view of an architectural design and is divided into: - frontal lessons, - classroom exercises, - development of classroom simple projects (preferably teamwork). The teacher uses assistants for teaching support (exercises and development of classroom simple projects). In the event of an extension of the health emergency from COVID-19, all the provisions that regulate the methods of carrying out teaching activities and student assessment will be implemented. In particular, the following methods will apply: the platform for carrying out the lessons will be the official Teams platform. Students are urged to carefully review topics in building science and construction engineering before the start of the courses and to point out any critical issues to the lecturer. The lecturer will evaluate the existence of these prerequisites at the beginning of the courses in order to possibly activate all the procedures provided by the Department regulations to provide the necessary support.

Attendance

Compulsory attendance is required for 75 percent of the classes.

Type of evaluation

A case study (simple architectural project) will be identified at the beginning of the course. This case study will be the subject of analysis, insights, design, and structural verification during the course. The project will be the subject of classroom group reviews during the course. The instructor may require interim deliveries of the material produced in order to assess the degree of development and proper execution of the same. The final examination will include an oral test for each candidate, which will focus on the discussion of the project carried out during the course and the theoretical topics indicated in the syllabus. Prior to the exam, delivery of all papers produced for the development of the project is required. All files of the papers will be sent telematically at least 7 days before the examination date through free online services (example: Googledrive, Onedrive, Wetrasfer, etc.). In the case of an extension of the health emergency from COVID-19, all provisions regulating the manner of conducting teaching activities and student assessments will be implemented. In particular, the following arrangements will be implemented: - the telematic submission of files related to the design boards and all the necessary papers for the conduct of the project (submission must be at least 7 days before the examination date), - the examination includes an oral test with theoretical questions and a discussion of the project carried out during the course, - the platform for conducting the distance exams will be the official Teams platform already used by students/ae to take the university courses.
