Estudo de viabilidade econômica na substituição das alvenarias internas de vedação em bloco cerâmico por Drywall em um edifício misto.

Abstract

The technological advancement has brought several improvements to the construction industry, including the development of alternative materials such as drywall partition walls, which can replace traditional ceramic block masonry and result in less weight on the structure, although it is more expensive. Therefore, this study was conducted to analyze the economic viability of this new material for construction costs, in accordance with the research objective, by intervening with improvements in the structure based on effort reduction, with the assistance of the TQS software. The result obtained indicated a reduction in the amount of material used in the structure, with steel being the most significant, with a value of 1024 kg. When combined with the value of drywall masonry, it led to a decrease in construction expenses, thus proving the economic feasibility of the replacement. It is concluded that although the drywall construction system brings a small cost reduction of 2.95% to the total cost of the project, it also provides other advantages, such as increased productivity during execution and reduced waste.
