Degree in Technical Architecture and Building Engineering

The Degree in Technical Architecture and Building is temporarily paused for new students

Topography

Description
On the topography course the student carries out ground elevations and re-planning of building work. Knowledge of the site where the building or urbanisation is to be constructed is essential. We often realise that we begin to plan a project without finding out about the site where it is to be built. Topography can condition a project for economic criteria or for sustainability reasons which can recommend that the project is adapted to the existing land. On the second course we go on site visits to appreciate that there is a long way between the project and the construction of a building where the presence of good professional as building director, in this case the technical architect, is necessary. Here we will check the importance of the topographic methods as a tool in the re-considerations of a project.

Previous Knowledge

This course is for students on their second year of Technical Architecture. Future technical architects need to have a realistic vision of the professional activity of the person in charge of carrying out a project.

Objectives

Students who complete our course on topography and Re-planning acquire the knowledge and develop the skills listed below:

1. To have a knowledge of the elevation and development of the topographic map in professional practice.
2. To use the latest tools and techniques for the RE-PLANNING OF WORKS:

The transversal profiles.
-How they are made.
-What information they provide and how we obtain it.

-Plan, layout and slope of a project.
-Slope agreements.
-Vertical curve agreements
-Co-ordinate calculations and re-planning of the curve.

- PRACTICAL EXERCISE 1.
SITE ELEVATION WITH OR WITHOUT CONSTRUCTION.
This exercise aims to a make the student aware of the project on the site. A calculation of the area of elevation of the site is made, obtaining definitive unevenness and levels. The height of an existing building is also calculated using topographical methods.
- PRACTICAL EXERCISE 2.
LEVELLING WITH A LEVEL.
The aim is to make a longitudinal profile of a street which needs to be renovated. Therefore a leveller provides us with the altimetrical contour of the points and its elevation.

- PRACTICAL EXERCISE 3.
ELEVATION OF A SQUARE TO BE URBANISED.
This exercise aims to carry out the elevation o fan urbana rea considering alitmetry and planimetry for its urban planning. The contours and uneven levels are studied in order to obtain a contoured map.

- PRACTICAL EXERCISE 4.
RE-PLANNING OF A PROJECT USING TOTAL STATIONS.
The direct application of the different re-planning techniques which the student has developed in the theory classes, where s/he has to use the equipment which is current lye used in topography. Having completed the Construction course, the student should have a wider knowledge of the building process, and can learn how to materialise a real case study using the Total Station.

Methodology

In this subject, the ability to work in a team and to organise and plan specific work is required.
The first part of the two-hour class is dedicated to the theoretical content and the second part is usually spent solving a case study in groups and then studying the results.
The dossier of these exercises is available at the copying department and the students hand it in at the end of the course.
It is very important to complete the exercise. The students often appear to `understand how it works,´ however in topography the result, and not only the planning or the idea, IS important.
When the student is familiar with the theoretical knowledge (usually alter a month), the practical exercises are started. These are done in groups of 3-4 people and 4 are done throughout the course. The fieldwork is compulsory as it is considered essential in the understanding of the course.

Evaluation Criteria

Objective 1: The student must show the ability to:

●Familiarise her/himself with the building plot (whether it is for building or urban planning purposes). The professional who carries out a project or who is in charge of it must have these concepts clear. The most suitable scale for a project or the difference between a contoured map and one with curved levels.
- The student must know the topographic equipment available and what it is used for. What information they provide and how precise they are in order to adapt them to the work in question. For example, a technical architect should know that a tachymeter and two readings, you can calculate the height of a building to a centimetre, or that a level can check the flatness of a foundry to millimetrical precision
- In the first part of the course the general aspects of topography and land are studied - methods to take the student `from the ground to the map.´ This process is also studied inversely. THE RE-PLANNING as an intermediate step between the realisation of the plan and the management of the building work. [A / D].

Objective 2: The student must show the ability to:

- Analysis of problems and the implantation of the project on the building work. Once the student has acquired sufficient knowledge on the first year of the degree, s/he will have to KNOW HOW TO USE the methods available in topography, in urban planning and construction.
- Four complementary practical fieldwork exercises based on the aforementioned theoretical knowledge. [A / D].
