Estudo comparativo de custos diretos entre o sistema light steel frame e o sistema de paredes de concreto aplicados a uma habitação de interesse social./

Abstract

The housing deficit situation in the country leads to the search for new constructive techniques which are fast-tracked and economically viable. This paper presents the problem of the housing deficit, the concept of Housing of Social Interest (HIS), the state of the art of a system that is becoming popular in the country, Light Steel Framing (LSF), together with a comparative study of the direct costs of a built HIS using the reinforced concrete wall system, a system already commonly used in state of Paraíba, and in LSF. The presentation of the LSF is done through each step of the its constructive process. The comparison of costs in the case study is done based on the budget of a dwelling already executed, provided by JGA Engenharia LTDA, and adapted to the LSF. The LSF shows a high execution cost in comparison to the concrete wall system, however, because of its smaller time, the system becomes viable due to its more fast.
