Technical Drawing

Career Objectives

Contribute to the construction and technology field through the display and graphic interpretation of a project, which serves as guide in its construction and *implementation phase.

Professional Profile

Professional who provides accurate information of a three-dimensional body through its representation in a flat surface, with its shapes, dimensions, characteristics and proportions to be able to work with its complete and precise information.

He performs in areas of architecture, civil works, mechanics, electricity, electronics and urban.

Specific tasks or activities carried out in the profession

He develops and handles any type of graphic projects.

He participates from the early stages of development of a design project making *sketches, *schemes and *diagrams of possible solutions to it; identifying its main risk factors or uncertainty factors, developing proposals.

Once finished, he formalizes the design by presenting the results in definite *technical drawings.

In the making of plans/blueprints:

He uses a graphic language of lines and symbols to make representations of one or several views of an object and thus to define its form and characteristics completely.

He applies pre-established standards (*ISO standards) to describe shapes, dimensions and characteristics of what he is going to represent, such as rules for presenting lines, *formats, *signage, etc. and ways to present pieces or pieces’ parts from different views, *cutaway drawings, etc.

He makes the representation of the *scale drawing.

He obtains measures of lengths, heights, widths, etc.

He makes use of measuring instruments (caliper, micrometer, etc.)

He uses geometric concepts for calculating areas, angles and volumes.

He makes use of specialized technological and computer resources.

He obtains 3D renderings of the objects.

He develops Structural plans which contemplate the rough structural work of a construction: their foundations (base), columns, beams, *slabs, etc.

He develops topographic plans which report on the location and the landform where the work will be built.

He develops architectural plans which allow displaying how the construction will be inside and outside, through: *Floor Plans, *Façade Planes, *Cutting Planes, *Perspective Planes; in order to indicate how a building or dwelling will be built, as well as which will be its appearance once finished.

He develops *health facilities plans, gas networks installations, drinking water supply systems and *pipelines; according to the regulations established by the Superintendency of Electricity and Fuels, regulation of Household Installations of Drinking Water and Sewerage.

He carries out the construction supervision interpreting the plans and technical specifications, so that they are met.

The technical specifications complement the information of the plans alluding to the types of materials to be used and some considerations to be taken in the construction process, to give the project an appropriate completion.

For instance: “the frames will be made of anodized aluminum and will have a silicone sealing all around them”, “External and internal doors are considered based on a stretcher frame and chipboard, type hardboard, 45 mm thickness according to the dimensions of the plane.

The external door frames will be made of fir wood and the interior doors made of pinewood, 1 ½ pieces”.

He performs the *material take off quantification of materials necessary for the construction work and develops a budget.

He interprets plans to find drinking water supply systems, gas networks or *pipelines, in order to carry out maintenance and repair work.

He performs *building surveying for restoration.

He carries out mechanical drawing, making representation of all sorts of machinery and vehicles such as engines, industrial machinery, cranes, motorcycles, trucks, airplanes, etc.

In this he performs:

General Assembly Drawing, which represents the machinery, together with all its parts.

Drawing of Parts, which represents separately each one of the parts of the machinery. -Useful for manufacturing.

Installation Drawing, which depicts how each one of the pieces are assembled to form the body of the machinery. –Useful for its assembly or repair and its later assembly.

He carries out electrical drawing, making the graphic representation of electric installations of industries, offices or dwellings or any construction which requires power supply.

He uses the symbology corresponding to circuits, switches, control panels, AC power plugs and sockets, etc.

He performs Electronic Schematics, representing the circuits that make up computers, amplifiers, transmitters, clocks, televisions, radios and others.

He develops Urban Planning, representing the organization of a city, with the location of its urban centers, industrial zones, streets, avenues, gardens, highways, recreational areas, among others.

He carries out procedures for building permission.

He carries out *expert’s reports.
