According to Picchi (1993), its participation decreases in the recessivos periods, whereas its growth is greater that the average of the country, at times of expansion. Civil Engineering is one of the branches oldest of engineering and its importance is Vital for the development of the society, as well as, for the interconnection between these. As producing of the technology the civil engineer it has undisputed participation in all the stages of the development of the societies human beings and the action of these professionals is the service of the improvement of the quality of life of the people.
