Objectives

The Circular Economy action plan identifies Construction and Demolition as one of the five priority intervention sectors.

This Course Unit is intended to alert the student to the importance of sustainability in construction and the role of Civil Engineering in the transition to Circular Economy

It is intended that the student acquires knowledge and tools that allow him to make technical decisions, duly substantiated, with regard to the design, dimensioning, maintenance, renovation / de.molition of works according to the premises of the Circular Economy in construction.

At the end of the course the student should be able to:

- make technical decisions that promote Circular Construction;

- dimension in civil engineering with the inclusion of recycled materials;

- know new construction and management technologies aligned with the principles of Circular Economy;

- be aware of national and international legislation on Circular Economy

Learning outcomes and competences

Environmental sustainability and the promotion of sustainable construction make the adoption of Circular Economy in Construction essential.

Thus, it is important to provide students with knowledge about the concepts associated with Circular Economy, strategic plans for its implementation and innovation technologies in order to enable them to apply them to construction.

The syllabus contents constitute a structured response to the objectives of the Course Unit, since they include information and training in relation to the various relevant aspects within the scope of the application of Circular Construction. The syllabus will provide students with technical knowledge and skills, which will allow them to intervene in a reasoned manner in the related fields, namely, promoting the valorization of different types of waste in the design phase and at the construction site.

Teaching methods and learning activities

The teaching model of this Course Unit will include theoretical, theoretical-practical and laboratory lessons. In the theoretical lessons, fundamental basic knowledge will be addressed and relevant theoretical knowledge will be transmitted. Theoretical-practical lessons will seek to reconcile theoretical presentations of the concepts and methodologies related to the subjects to be studied, presentation and discussion of practical cases that represent good practices or situations to be avoided within the scope of Circular Construction and, also, to promote contact with relevant projects through invited speakers and (or) visits to works. In laboratory lessons, tests demonstrating the application of waste as raw material in construction will be carried out.

The evaluation will be of the distributed evaluation type without final exam and consists of two tests (T1 and T2). The first one (T1) will take place during classes and the second one (T2) will take place during the final period of evaluation. Each test has a weight of 50%.

Eligibility for exams

Achieving final assessment requires compliance with attendance at the course unit, according to the ME.C assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.

Calculation formula of final grade

CALCULATION OF THE FINAL CLASSIFICATION:

The final classification is defined on the basis of a distributed assessment without final examination consisting of two tests T1 and T2 being the first, T1, held during the class period and the second test, T2 held during the examination period. Each test has a weight of 50%.

The final classification, CF, results from the following calculation formula

CF=CT1×50%+CT2×50%

Where,



CT1 - classification of the assessment test 1 to be held at a date to be announced

CT2 - classification of the assessment test to be held in the exam period



NOTE 1: All students enrolled in the course unit are graded according to this assessment method.

NOTE 2: Students who, for reasons of force majeure, were not able to take Exam T1 and whose absence justification has been accepted by the DEC, will be assessed at a date and time to be arranged with the teachers.
NOTE 3: In the Appeal period and also in the Improvement examination the student attending the current year may choose to take that Examination in one of the following three modalities:
(i) Repetition of Test T1
(ii) Repetition of Test T2
(iii) Taking an exam about the totality of the subject including both parts T1 and T2.

Classification improvement

In the Improvement Examination the student attending the current year may choose to take this Examination in one of the following three modalities:
(i) Repetition of Test T1
(ii) Repetition of Test T2
(iii) Taking an Exam about the TOTAL subject including both parts of T1 and T2.
