RESUMO

The aim of this work is to apply the Lean Construction plan, based on Toyota Production System, as the main strategy for the steel structure assembly in a commercial building. The Lean System target is to increase the productivity in the construction process by considering the synchronism between the logistic activities and the steel structural erection. This synchronism can be obtained by following the Lean Logic of reducing the time delay, the elimination of inventory in the building site and the organization of simultaneous teams for the assemblage of the steel parts. The material flow and the sequence of activities are represented in a value stream map, in order to identify the time wasted during the process and trying to otimize sequence of operation. At the end, by analyzing a particular project of a building at the center of Rio de Janeiro, the critical problems involved in a steel construction were identified and some alternative solutions for these problems, based on Lean System, are proposed.
