Sistemas construtivos pré-fabricados : uma abordagem LEAN

With the advent of the 4th industrial revolution, traditional construction methods no longer met the needs of society. Thus, prefabrication of building systems has never been so evident. The competitiveness of the sector and the complexity of the projects have increased substantially, so much so that the survival of companies in this field is associated with their ability to optimize resources and reduce waste. Therefore, the application of Lean Production concepts, which focuses on waste reduction, is not only a viable alternative, as it provides mapping tools and waste reduction, but also a desirable approach for philosophically addressing the entire system in the world. which company is inserted, positively impacting its culture and the culture of all parties involved. The aim of this paper is to indicate, through a flowchart of activities of a real Prefabricated company, points where lean concepts and tools would add value to the process. For that, the production steps were raised, detailing in a flow chart the Framing macroprocesses, form set-up, concreting and preparation for expedition, identifying points where some of the tools of Lean philosophy could be applied. The implemented tools have reduced labor costs and eliminated waste identified in the process value stream mapping.
