Aplicação dos princípios da construção enxuta e métodos racionais na construção civil: estudo de caso

Abstract

The construction industry has externally observed the accelerated growth of the other production spheres while it is trapped in a conservatism typical of this sector. The civil construction sector is well known and marked by being a sector with high rates of waste, high rates of rework and disqualified manpower. Since the emergence of new philosophies and working methods such as the Toyota System and Lean Thinking in the early 1990s, several sectors from different industrial sectors have sought to adapt these new principles to their production systems. This paper aims to show the applicability of the 11 principles of Lean Construction in the execution of a 14-storey residential building and also to show the efficiency of rational mechanisms and methods developed and adopted that improved the level of productivity in some activities. This philosophy, based on the principles of the Toyota Production System, consists in the search for constant improvements, applying techniques that aim to reduce waste during production processes, standardization and improvement of activities, as well as reduction of inventories and increase of productivity.It is important to emphasize the importance of the manager or technical person in charge of having knowledge about the productive processes and activities to be performed inside and outside the construction site, as well as the need for the standardization of the executive processes, inspection and incentives provided to employees
