Aplicação de mapeamento do fluxo de valor e dos princípios da construção enxuta na macroatividade de alvenaria

Abstract

As the construction industry has experienced moments of crisis, due to the economic problems facing the country, the shortage of skilled labor, waste of large volumes of materials on the construction site, and mainly, for managerial problems on some of the companies, for not adopting management practices becoming more efficient, this industry is unproductive. In this context, companies that want to be ahead of competitors, seek to introduce managerial philosophies, such as lean construction, which aims to reduce activities that do not add value, simplifying activities and eliminating unnecessary movements, improving product flexibility, introducing continuous improvement in the process. The objective of this work is to analyze and propose improvements in the production flow in a construction site, for this, the concepts and tools of lean construction were applied, as the value stream mapping, through it, it was possible to verify the wastes of some masonry step activities, and propose a 40% reduction in lead time of the process. The case study is based on the methodology proposed by Koskela (1992), which comprises a type of analysis of the productive chain, with the intention of building with the minimum of waste.
