Aplicação dos princípios da produção enxuta à construção civil processos gerenciais, técnicas e desafios para o caso brasileiro

Abstract

Civil engineers are licensed to exert several activities related to the design, planning and execution of urban and rural buildings. In recent years, the increasing complexity of the projects has motivated these professionals to direct their efforts towards the construction management. Then, lean production is presented, whose principles and techniques have significantly influenced the management theories of civil construction; this productive system, which proposes a significant increase in the productivity of organizations based on the radical reduction of waste, currently gave rise to lean construction. In this context, the present study presents the principles that rule lean production and construction systems, the way in which management processes are structured in design, planning and production activities, as well as exposing techniques and procedures that can be used in construction. In addition, some of the main Brazilian challenges to be faced by entrepreneurs in adopting this system are reported, as well as plans to assist them in the implementation. From this, it is emphasized that the adoption of lean practices will not occur immediately in companies, and that it may take years for it to happen completely. Finally, it is concluded that the success of the implementation is linked to some factors such as the deep knowledge of lean practices and principles, the mapping of value flows, the speed with which changes are made, the real engagement of the workers directly linked to the productive processes, the support of the company's top management, as well as the existence of some type of crisis that motivates changes.
