Teaching method

Theoretical and practical classes; study visits; design guidance 

Evaluation method

The assessment is done by designing a project (divided into two parts - two group (max 4 elements) assignments: 20% + 30%) and the resolution of two individual written examinations (20% + 30%).

The group assignements will considered as "frequência".

A minimal grade of 9,5 in each evaluation components (project + written examinations) is required.

The Frequency is valid for two years (the one in which it is obtained and the next one).

IMPORTANT NOTE: In the assessement of the assignments, the questions can be asked only to one student and the same grade will apply for the whole group. All students should be aware of all aspects of the work.
