Uma contribuição ao estudo do processo de projeto de empreendimentos em construção metálica: uma visão segundo a nova filosofia de produção.

Abstract

Steel construction first appeared in Brazil 50 years ago, but only in the last fifteen years has it been rediscovered by contractors and professionals that have become more interested in this kind of building technology. There are many factors which regulate steel construction development, but incentives are growing in order to increase the steel consumption in civil construction, because this consumption is lower than others countries. Talking about the industrialization of construction, the integrated design is very important and the New Production Philosophy (lean production) is a good reference theory for the design process improvement. Thus, the design process improvement is fundamental to enhance production process efficiency. The characteristics of the product are defined by the design and these characteristics influence production costs. This study starts with an exploratory research, looking through the definition of the case study focus. Aspects like market, costs, technology, planning, productivity, standards, design, waste, quality, labour and problematic topics about steel construction were examined and deficiencies in the design stage were noted. After this, the study investigates two design processes of steel construction projects, analyzing then in accordance with the New Production Philosophy. Finally, this study suggests some actions and policies for improving the design process in steel projects.
