FERRAMENTAS LEAN PARA EMPREENDIMENTOS COM SISTEMA DE PAREDE DE CONCRETO ARMADO MOLDADA IN LOCO.

Abstract

The constructive system of cast-in-place concrete walls is a method in which industrialized forms are used, embedded in the work itself, applied directly with concrete. This is a practically entirely industrialized system. Its great differential compared to traditional constructive models is mainly linked to the leaner cost due to its shorter execution time. With the application of new production methodologies to this system, it is possible to achieve not only the efficiency that the constructive method already promises, but also to propose a continuous improvement to the sector, increasing productivity, eliminating waste and adding value to the product. Within this aspect comes Lean Construction, a philosophy that carries tools and principles that, when properly applied, result in the optimization of processes and deliveries of a quality final product. This work is a study of the bibliographic review in order to investigate, select and propose the application of some tools that follow the principles of the Lean Construction philosophy, to the constructive system of concrete walls, with the intention of cooperating with the improvement of the sector performance. It was found that it is possible to apply Lean tools to the construction method of reinforced concrete walls cast "in loco" and this application brings several benefits to the system, such as: continuous improvement to the construction process; increased transparency of processes; cycle time reduction; increasing the value of products and reducing activities that do not add value. These results can be achieved through the use of tools such as: 5s Program, Andon, Kanban, PDCA Cycle, Physical Arrangement, Last Planner System (LPS), Line of Balance and Value Stream Mapping.
