1. General information

1.1. Aims of the course

Within the studies of Technical Architecture it is essential to know what we commonly call "work equipment and auxiliary means", making known to the students the main characteristics, uses, functions, performances, productions, main components, etc. ., of the equipment, machines and tools that are commonly used in building and urbanization works. With this you will be familiar with the design and planning for the correct choice of said equipment, tools and machinery in each type of work and / or in each phase of the same, as well as its most favorable location.

It will also analyze the needs in terms of supplies, especially energy that the equipment and machinery will need for proper operation, should be able to calculate the provisional connections of work of electricity, water, pluvial and fecal drainage, etc. . linked to the period of completion of the works.

1.2. Context and importance of this course in the degree

The subject of EQUIPMENT OF WORK is the fourth contact that the students of the Degree in Technical Architecture have with the constructive fact, from which one begins to become aware of how the process is developed in the global construction and of the paper (or papers) played by the Technical Arqutecto within it.

It is part of a group of specific training subjects and mandatory character structured throughout the four courses of the degree, which will provide much of the specific skills and subsequent professional skills of these graduates.

1.3. Recommendations to take this course

The current curriculum does not establish any prerequisite to take this subject. However, it would be advisable not only to possess the basic knowledge of mathematics, physics, fundamentals of materials and graphic expression, but also to have completed and / or passed the following subjects:

• Construction Materials I.
• Construction Materials II.
• Structures I and II.
• Building I, II and III.

2. Learning goals

3. Assessment (1st and 2nd call)

4. Methodology, learning tasks, syllabus and resources

4.1. Methodological overview

The methodology followed in this course is oriented towards the achievement of the learning objectives. A wide range of teaching and learning tasks are implemented, such as theory sessions, practice sessions, exams, tutorials, and autonomous work and study.

The teaching methodology is based on a strong interaction between the teacher and the student. This interaction is materialized by a division of labor / responsibilities among students and teachers.

4.2. Learning tasks

This course is organized as follows:

• Theory sessions: theoretical concepts of the subject will be explained and illustrative practical examples to support the theory will be developed when deemed necessary.
• Practice sessions: problems and case studies to complement the theoretical concepts studied will be made. Students using notes, rules and bibliography, will real work in class, which will be delivered for review before finishing it.
• Autonomous work and study
  • Study and assimilation of the theory presented in lectures.
  • Understanding and assimilation of the problems solved in practice sessions.
  • Autonomously resolution of problems and proposed examples.
  • Preparation of practices, information search, group meetings, preparation of scripts and reports.
  • Preparation of the written tests of continuous assessment and / or final exams overall assessment. 
• Tutorials. They can be on-site or online.
