Análise da viabilidade de construção de casas populares utilizando método light steel frame na região de Dourados - MS

Abstract

The continuous and growing demand for popular houses create a search fir ways to decrese the costs and increase the produtivity of civil construction. Due to the obsolete and ineficiente construction methods, this field in comparasion to others áreas is considered behind the times. From this demand, this article shows through a bibliographical survey, a comparasion between the method light steel framing and the structural masonry for a single Family house, located in Dourados – MS. The constructive system Light Steel Frame (LSF), consist in a structure made of coldformed galvanized steel panels and its seal is made of drywall and cement plates. This method is considered industrialized and modern, being widely used in North America and Europe, however poorly used in Brazil. Using a house model with 42 m² and its dimensions adapted and sized for the construction in LSF, a budget for the labor and the cost of the materials was made, as well as a analysis of the efficiency of both construction method. From the obtained data was conclued that a Light Steel Framing house showed a cost 50% higher than structural masonry house, but the LSF house can be executed in a half the time. With this finding is conclued that a construction of a house using LSF is impraticable. Reviewing the construction of popular housing in a wide scale, this method can be more economical than the structural masonry when analyzing the total cost of the Project.
