Resumo
O setor da construção civil é caracterizado por apresentar altos índices de desperdícios em seus projetos e baixa eficiência produtiva, necessitando de modificações em seu sistema produtivo tradicional, para que, dessa maneira, consiga atender de forma rápida e ágil às exigências dos seus clientes. Os resultados adquiridos pela indústria manufatureira com a utilização da filosofia Lean Manufacturing motivaram a adaptação desta filosofia para a indústria da construção civil, costituindo uma nova filosofia que foi intitulada de Lean Construction. Neste contexto, destacou-se o Last Planner System, que tem como principal objetivo aperfeiçoar o processo de planejamento e controle da produção por meio de medidas que procuram diminuir as incertezas do planejamento. Contudo, este modelo, segundo autores, necessita ser complementado para ter sucesso no gerenciamento de obras. Desta forma, para sanar estas problemáticas, através de um estudo de caso, este trabalho tem como objetivo implantar o Last Planner System integrado com o modelo tradicional de Gestão de Projetos que utiliza o método Critical Path para o planejamento da produção. Assim, os
métodos de Gestão de Projetos e a filosofia Lean Construction surgem como uma opção para aperfeiçoar os processos produtivos no canteiro de obra, trazendo benefícios por meio da diminuição de desperdícios e extraindo maior produtividade das equipes de produção. Os resultados observados com a implementação das ferramentas foram significativos. Devido à constatação de um crescimento no percentual de planos concluídos e a criação de um fluxo contínuo na execução das atividades, estes fatores refletiram no aumento do índice de
desempenho da obra. Além disso, observou-se que a integração das ferramentas concedeu à empresa um sistema de planejamento e controle nos três níveis gerenciais, estratégico, tático e operacional. Em vista dos argumentos apresentados, pode-se inferir que a implementação das ferramentas pode oferecer resultados positivos para o gerenciamento de obras na construção civil, diminuindo os desperdícios de processamento, produção, transporte, movimentação e espera.
The civil construction sector is characterized by high rates of waste and low productivity; it need changes in its traditional production system, so that, in this way, it can quickly and quickly solve the needs and demands of its customers. The results obtained by the manufacturing industry with the application of the Lean Manufacturing philosophy, encouraged the adaptation of this philosophy to the construction industry, denominating it Lean Construction. In this context, the Last Planner System was highlight, which the main objective is to improve the process of production by planning and controlling through measures that seek to reduce planning uncertainties. However, according to authors, this model needs to be complemented in order to be successful in the management of constructions. Therefore, in order to solve these problems, through a case study, this work aims to implement the Last Planner System integrated with the traditional Project Management model that uses the Critical Path method for production planning. Thus, Project Management and Lean Construction emerge as an alternative to improve production processes within the construction site, bringing benefits by reducing waste and providing greater productivity. The results observed with the implementation of the tools were significant, due to a growth in the percentage of plans completed and the creation of a continuous flow in the execution of the activities, these factors reflected the increase in the performance index of the construction. In addition, it was observed that the integration of the tools gave the company a system of planning and control at the three levels of management, strategic, tactical and operational. In view of the presented arguments, it can be inferred that the implementation of the tools can offer positive results for the management in the civil construction, reducing the wastes of processing, production, transport, handling and waiting.
