Utilização de ferramentas Lean em uma obra de construção civil em João Pessoa, Paraíba: um estudo de caso

Abstract

The construction industry faces persistent challenges in its evolution, often progressing slower compared to other sectors. Therefore, it is imperative to constantly seek improvements to overcome these obstacles. In this context, the philosophy of Lean Construction emerges as a crucial approach to solving problems such as low productivity and waste. This study focuses on the application of a Lean tool, the A3 Report, directed towards a construction project in the city of João Pessoa, Paraíba. To support this analysis, various bibliographic sources were consulted, including books, articles, theses, and academic papers, which clearly highlight the theory of Lean Construction and the use of the A3 Report, as well as practical examples of its implementation. The A3 Report was utilized to study a specific service, in this case, the construction of a reinforced concrete slab, with the aim of identifying ways to make its execution more efficient and productive. After detailed analysis, solutions were proposed aimed at improving service performance, assessing whether there was an increase in productivity, and whether the planned deadline was met. The results indicated that the implementation of the A3 Report resulted in significant improvements in the process, both in technical and productivity aspects, culminating in the completion of the service within the previously planned time.
