The estruturao in the way of management of the cities if has modified throughout history, mainly in function of the urban concentration, and the growth of the population. In such a way, it practical the usual of public administration is added, new challenges; new words of order are incorporated the vocabulary technician: support, autonomy, human development, equity, reduction of the inaqualities, preservation of the environment, democratic management, quality of life, etc. New concepts start to be used for world-wide chains of urbanism and environment. Brazil, these concerns are translated some laws, where if they detach Federal Constitution e, more recently, the Statute of the City. In common, in the base of these concepts, this the promotion of the human being, with the equality of chances for the full development of its capacities and in harmony with the environment, becoming the cities more jousts, human beings, democratic and sustainable.

process of sprouting of occupations is part of the occupation dynamics and expansion of the cities, fruit of the problematic habitacional deficit and mainly of the social one, reaching not more only great cities, but also small average cities. The concern in the urban way in such a way brightening up the resident problems of the population in the areas of occupations, how much of the ambient damages caused by the occupations, since many had consolidated in areas of ambient preservation or areas of risk, she has been express in government programs. The demands of these areas of occupations are of total urban infrastructure lack and social, since the interventions of the power public have looked for to brighten up the effect in the urban way, ambient and social, they are treated as emergenciais and the implanted programs nor always are monitored. The monitoramento of the implanted actions is the form to guarantee the implanted management of the programs and projects, supplying disgnostic and subsidies for the planning and priorizao of new actions.

In the operation of welding, the pipes are lined up so that they are welded in the extremities and, for this, are necessary that the welding machines are carried throughout the passage. During this process, the workers are displayed to the noises emitted for the tractor that carries the machines, for the noise emitted for the retroescavadeira that raise the pipes it lines up and them, for the sanders that rectify laces of weld and for the proper weld machines. After the welding of the pipes in its extremities, the area is displayed causing its oxidation, that is removed through the jateamento for, after that, to be coated by a blanket of protection against corrosion. The high level of noise is generated during the jateamento for the compressor, the escavadeira, for agricultural tractor that carries all the equipment and for the equipment of jateamento properly said. As the passage of the Cacimbas-Bar gas-line of the Stream he is very extensive, the pertinent activities to its construction constantly changed of place, becoming thus a itinerante workmanship. Due to this mobility, the measurements of noise had not been carried through always in the same local but, yes as the team if dislocated throughout the stretch. Therefore, the measurements in those stretches had been prevented where it could occur interference of the external way in the measurement, as for example in next places them highways, where the vehicles mainly of great transport emit a level of significant noise, in places next to plants or close to noisy activities that could influence directly in the values of the measured sound pressure levels. In such a way, it was looked to evaluate the noises emitted only and so only for the specific equipment of the evaluated activity and without the interference of external sources. main emitting sources of noise, of the activities of welding and jateamento, are listed in Table 01, together with the NPS emitted for each one..
