Análise comparativa de custo de materiais entre uma estrutura em concreto armado e metálica: estudo de caso na cidade de Palmas/TO

Abstract

There are constantly advances in technology, and with that, several segments of the industrial market are benefited. In this context, one area that is gaining influence is that of civil construction. New technologies that can be applied, innovative materials, increasingly useful tools, all directly influence civil construction today. This range of action possibilities raises questions about the efficiency and effectiveness of these technological variability in the field of engineering and it is in this context that this work is supported. This research proposes a comparison of material costs considering two different construction systems (reinforced concrete structure and metallic structure), in which a building located in the city of Palmas / TO is based on the study. Starting from an existing structure in reinforced concrete, with the purpose of proposing a metallic structure, the CYPE 3D software was used, in addition to catalogs of companies that operate in the supply of the necessary materials. For the survey of costs, the compositions and inputs of the National System of Research on Costs and Indices of Civil Construction (SINAPI) were considered, in addition to surveying the market. In this context, it was found that the costs of the metallic structure were approximately 61% higher than the costs of reinforced concrete, since the precision of production of the metallic parts, associated with the agility of construction and the specialized labor directly influence the cost of the construction. constructions.
