Construção metálica enxuta através de padronização de tarefas e projetos

Abstract

Construction on the metal structure is used in the world since the earlynineteenth century, as a constructive process fast and efficient. Brazil has a deficit in the housing index due, among other factors, the backwardness of the traditional process. Therefore, the use of metal structures becomes an alternative to reduce the construction time of houses, because there are many advantages offered by the material - lower weight of the structure, better use of space and building fast and clean. But one of the celebrated characteristics of the steel between the architects and engineers is the creative freedom it affords, allowing bold designs, with modern designs. The adoption of steel in the project design is essential to the concept of sustainability of the work: the material is recyclable and construction from metal structures characterized by being a clean system. Questions about when to build in steel is often at the time of star the work. In this time is the moment to list the many advantages of using steel structures may include: agility, organization, accuracy, reduction in work time and quality. However, this is not the only factor to taken in consideration. The country has great potential steel, as it has good chances of making steel an important ally in the development of sustainable construction techniques. The aim of this study was to identify the technical feasibility of application of steel structures in construction. To this construction present agility, less expenditure of labor, more security, more versatility through to project that leading to lean construction. The Toyota production system and lean production with their definitions of value, value chain, flow, production and perfection, are considered the theoretical reference to produce a lean construction. The traditional way to understand and manage the building is being replaced by those governed by the new conceptual base. The work also attends the study of the design and production of prefabricated metal. This process is of decisive importance for increasing the efficiency and quality of services and products of steel construction industry. This form of production can be understood as a lean metal building. To understand the developed of the project of metal structure is necessary to know what the steel, as construction element, means a rationalized work,for which the factory will produce parts the was optimized in the architectonic project and will, after transportation, mounted in the construction site. In this work, we demonstrated, by case study, the advantages and restrictions of the process of project in metal structures. The technical languages, planning and coordination capacity andmanufacturing process knowledge treated here permit a better vision of how used the functionaries and formals possibilities that involve the use of this sophisticated construction. As result, this study suggests how is a possible gain project from the most audacious to the most traditional.
