Resumo
Devido aos índices de perdas de tempo, insumos e baixa produtividade no setor da construção civil, surgiu o interesse de adaptar os conceitos da construção enxuta neste setor. O objetivo principal deste trabalho consiste em verificar o impacto da aplicação das ferramentas 5S e Last Planner System (LPS) da construção enxuta em um estudo de caso (processo de assentamento de pisos cerâmicos) na redução das perdas. O levantamento de dados ocorreu em uma obra unifamiliar, iniciando desde a reformulação da paginação original até a fase de assentamento dos pisos cerâmicos. Inicialmente é apresentada uma revisão bibliográfica, onde são apresentados os conceitos necessários para o desenvolvimento do trabalho e, após, a partir destes conceitos, é feito o levantamento de dados. A pesquisa realizada demonstrou a variação da quantidade de pisos cerâmicos necessária para os dois cenários de paginação - a proposta pelo projeto original e a repaginação sugerida. De um modo geral, considerando todos os ambientes em que houve a repaginação do revestimento cerâmico, obteve-se uma redução na ordem de 27,92% (vinte e sete vírgula noventa e dois por cento) do quantitativo de pisos cerâmicos necessários para cobrir a área e a redução no importe de 27,72% das perdas por cortes e quebra, o que se traduz em índices muito bons. Após os resultados, fica a sugestão de que, para melhorar e otimizar os resultados obtidos, essencial um projeto de paginação para o assentamento de pisos cerâmicos mais racional e previamente estudada, com o propósito de evitar cortes excessivos e retrabalhos durante a execução, além de facilitar a logística de compra e armazenamento de materiais.
Due to the high rates of time and input waste, and low productivity in the construction industry, interest arose in adapting lean construction concepts to this sector. The main objective of this study is to verify the impact of applying the 5S and Last Planner System (LPS) tools of lean construction in a case study (ceramic tile installation process) on reducing losses. Data collection was conducted on a single-family project, beginning with the reformulation of the original layout and continuing through the ceramic tile installation phase. Initially, a literature review is presented, presenting the concepts necessary for the development of the project. Based on these concepts, data collection is then conducted. The research demonstrated the variation in the quantity of ceramic tile required for the two layout scenarios—the one proposed by the original project and the suggested redesign. Overall, considering all the environments where the ceramic tile was refinished, there was a 27.92% (twenty-seven point ninety-two percent) reduction in the amount of ceramic tile required to cover the area and a 27.72% (twenty-seven point seventy-two percent) reduction in losses due to cuts and breakage, which translates into very good performance. Based on the results, we suggest that, to improve and optimize the results obtained, a more rational and previously studied ceramic tile installation design is essential, aiming to avoid excessive cutting and rework during installation, in addition to streamlining the logistics of purchasing and storing materials.
