Estudo comparativo de custo e planejamento entre os modelos estruturais de concreto armado e perfil metálico para uma obra residencial.

Abstract

The present study aims to compare budget and planning of the same building in two different structural models, which are the metallic structure and reinforced concrete. Its aims to dimension both structures, to withdraw the necessary amount of information for the execution of both structures, and then calculate the necessary amount of time to build both structures and finds the total cost of both structures, considering the current prices of the civil construction market and the SEINFRA cost table. The metal structure was calculated using the CYPE3D software and the reinforced concrete structure was calculated using the TQS software and all the quantitative that were extracted were withdraw through them. The elaboration of the budget sheets of both structures were made by using the Excel software, based on the prices of the current construction market scenario, caused by the COVID-19 pandemic. The structure made in metallic profiles was 123% more expensive than reinforced concrete. The elaboration of the needed time for the execution of both buildings was also done using the Excel software, where the metallic structure was shown, through calculations, to be executed 68% faster than the one made with reinforced concrete, showing that the two structural methods have a considerably large relation both in cost and planning ratio.
