METODOLOGIA DE PLANEJAMENTO E CONTROLE DE OBRAS DE PEQUENO PORTE COM USO DA LEAN CONSTRUCTION

Abstract

The civil construction industry uses traditional execution methods that have been incorporated into its production chain for years. This management system is often associated with deficiencies in the planning and control process, which increases deadlines and costs and lowers product quality. Studies indicate that this problem is even worse in small and medium-sized builders companies that carry out small-scale constructions, where there is no well-defined management plan, nor well-systematized procedures, and there is an accumulation of functions in professionals, who are based on their experiences and empirical knowledge for decision making. That said, in order to become more competitive, meet customer requirements, add value to products and increase productivity, companies in the sector have been seeking new management methodologies. One of the management philosophies that are being incorporated into the sector is lean construction, which is based on reducing waste in the production process and encompasses areas of design, planning, execution and control. The present work sought to list, through a vast bibliographical research, planning and control actions based on the lean philosophy, these were adapted for use in small works and systematized in a stock chart. To verify the feasibility of applying the proposed chart, a form was prepared and sent to civil engineers who work in small and medium-sized builders companies in the execution of small constructions, in order to assess the applicability of each of the proposed actions. In addition, the form had questions about the professional's level of knowledge about lean construction, planning and management techniques and whether he applies them in the routine of the company that work for. Based on the results obtained, it can be concluded that lean construction and planning and control techniques are still little known by the niche of participating professionals, but that they consider them of paramount importance for the improvement of time, cost and quality indicators in the constructions. . Finally, the actions proposed in the chart showed a high degree of acceptance by the evaluators and it is expected that they will contribute to the development of this follow-up.
