The Economic Feasibility of using Driwall in a Civil Construction work in the City of Manaus

In recent years, a growing demand for construction methods has been noticed, aimed at optimizing construction processes and reducing costs, especially with regard to sealing. The Drywall technique (dry wall) is a constructive method that attends to these constructive first fruits and aimed at the perception of sustainability. The general objective is: to present a cost-benefit comparison of the use of “drywall sealing” in comparison with masonry in ceramic blocks, based on the feasibility study of a project in the city of Manaus. Identify the advantages and disadvantages of using the vertical sealing system using the masonry system with ceramic block (conventional) and Drywall. To achieve these objectives, quantitative research (in databases such as Scielo, Public Domain, CAPES and renowned institutions) of an exploratory nature was carried out, with inferences and qualitative data collection from personal experience as professionals working in the field of Civil Engineering and sedimented through bibliographic research limited to the period from 2010 to 2021. The results point to an initial cost reduction of around 20% to 30% of the total cost of the work. It is concluded that even despite the higher cost of acquiring Drywall, its use related to direct costs represented a reduction of 22.68%, not counting the cost reduction related to costs with foundations (which represents something around 9% to 12%, making it economically viable and at the same time regarding the quality and strength of internal seals.
