Análise comparativa de viabilidade econômica entre alvenaria estrutural e estrutura de concreto armado convencional

Abstract

With the advancement of the real estate market and the development present in civil engineering in the country, the importance of studies on construction processes is great, in order to evaluate the most economical and quick way. In view of this, the present work consists of a cost comparison between structural masonry construction systems and conventional reinforced concrete structures and sealing masonry enclosure, in the closing stage, for a small to medium-sized single-family residence. Initially, a brief bibliographic study on construction systems was carried out, showing the main advantages and disadvantages for each construction system. To carry out the comparison, the same project was adopted, a single-family residential building, with 103.96 m² of built area, located in the city of Anápolis/GO, in order to carry out the budgets for each of the proposed methods, using the values ​​of reference provided by the SINAPI table of Caixa Economica Federal. Analyzing the results obtained in this study, it was possible to verify that for the work under study, there was a significant difference between the two budgets. For the conventional method with reinforced concrete structure and sealing masonry, the most expensive total cost, being R$49.068,60. Meanwhile, structural masonry was the most economical method among the two analyzed in this study, with a total cost of R$39.677,32. Therefore, it is important and necessary to modernize civil engineering, which has mechanisms for this, since there are currently several constructive systems, which can be economically viable, minimizing waste and even improving the quality of the executed buildings.
