The case study is a stimulating stage in training and learning which aims, through a real situation of a company, industrial sector or research, linked to the forestry-wood sector, to develop not only the knowledge of students, but above all the know-how and interpersonal skills of managers and leaders. The case study is therefore oriented towards active learning of the students through group reflection and discussion in a real situation.

The different subjects of study are proposed by industrialists, professionals and researchers and teacher-researchers. The themes of the subjects are interdisciplinary, scientific, technical, or socio-economic.

To meet the client's request, the student uses his or her previous knowledge and combines it with his or her newly acquired knowledge. Supervised by one or more pedagogical tutors, the group of students will be in charge of developing instructions, procedures, specifications, reports and study results from the results of tests, trials and/or surveys, in order to meet the client's request. Dialogue with one's peers, through exchange, confrontation or argumentation, contributes strongly to the good conduct of this project.

History of construction and contemporary architecture

Challenges and specificities of timber construction operations:

• Design: main structural checks, envelope, acoustics, etc.
• Implementation: particularities and organization of the sites.
• Operation: hygro-thermal performance, comfort and well-being, etc.
• Longevity and end-of-life: life cycle analyses of buildings, recyclability, re-use.

Noble woods in crafts for cabinetmaking, marquetry, violin making, etc.

Uses of industrial wood: 

Wood materials for packaging (pallets, crates, tanks, etc.)
