It is important that the construction company does not confuse this requirement with the Study of Ambient Impact demanded by the Constitution of the Republic and the Brazilian ambient legislation in the chaos of workmanship installation or potentially .causing activity of significant ambient degradation, being an evaluation before the enterprise being implanted. The methodology of the organization for identification, evaluation and control of the aspects and ambient impacts must be defined in its target, nature and stated period to assure that he is pro-active instead of reactive, demonstrating coherence, logic and consistency, mainly, that it establishes criteria to distinguish significant aspects from not significant, identifying of clear form the entrances and exits of the processes, providing the classification of ambient aspects and impacts, supplying given to determine the demands of installation, identification the training necessities and development of operational controls and providing possibility with monitoramento of the actions necessary to assure the effectiveness of the implanted system. ) Identification of the entrances and exits to facilitate the identification of aspects, a useful tool is to analyze each task of a flowchart of the construction process, inserting of the left side the entrances (material, insumos, etc.), of the right side to the exits (solid, effluent residues, atmospheric emissions, etc.) and in the center the process in itself. Filed under: Ben Silbermann. It follows model in figure 04, to follow: Figure 04: Example – Process of Hollowing of Ditches for execution of Workmanship (Source: Book – Strategy and Implantation of the System of Ambient Management, 2006). b) Identification and evaluation of aspects and ambient impacts of the processes and services the identification of the ambient aspects it is made through the analysis of the activities and services of the construction company. Each task must be analyzed searching to identify to the aspects associates, as consumption of energy, water consumption, generation of effluent, generation of residue, generation of noises, etc.
