Análise do modelo de gestão enxuta na produção de edificações em Light Steel Frame

Abstract

This work aims to analyze the management model applied to the production of buildings in Light Steel Frame (LSF), considering the principles of lean construction. For this, a case study was carried out in a construction enterprise development in the city of Uberlandia – MG. The stages of assembly and installation of the metallic structure of five buildings in the LSF system were analyzed, grouping them in three scenarios according to the location and the method of execution. It was collected information about the production process in order to identify the conversion and flow activities and the costs of implementation and productivity in the analyzed scenarios. Qualitative data were obtained from visits during the performance of the works and images obtained by unmanned aerial vehicle (UAV) and quantitative data through the planning and management system – Previx. Results showed that 75% of the activities carried out at the construction site did not add value, with losses due to transportation being more significant. Professional experience contributed to the definition of more assertive deadlines and goals, as well as the identification of assumptions and bottlenecks (constraints) contributing to the continuous improvement of the production process, by reducing the losses, flow activities, cycle time and the variability of process.
