Teaching method
Teaching is provided by theoretical-practical sessions of 4 hours each where it is present technical concepts whenever possible with documented examples, and resolve quantitative problems. Field trips are planned to ornamental stone and aggregates quarries. All information and presentations are available on the Web (CLIP).
Evaluation method
The assessment consists of conducting two tests of three hours with a theoretical part and a practical part (with consultation). Each test counts for 50% of the grade, with partial quotations of 30% for theory and 20% for practice.
Frequency is not considered.
