Análise comparativa entre vedações verticais internas na construção civil: bloco cerâmico e gesso acartonado(Drywall)

Abstract

As the market becomes more competitive, Brazilian construction companies seek solutions to increase productivity and reduce costs and waste in the execution of the service, in order to transfer this result to the customer. Thinking about it, this paper presents a comparative analysis of the costs and benefits between two types of internal vertical sealing: masonry with conventional ceramic block, and the plasterboard (Drywall), a material that is expanding in the national market. From a residential project, the following items were analyzed: material cost, labor and production time for service execution. Necessary items were chosen for each constructive method, as well as the specification of the drywall plates to be used, afterwards, we carried out a comparison using the Table of the National System of Research of Costs and Civil Construction Indexes for an equivalent cost in both constructive systems. With the results of each method, the analysis of the results and the comparison of productivity and the economic comparison were carried out, proving our hypothesis that, for this case, the masonry method with drywall was more economical, profitable and resulted in a cleaner construction.
