Análise comparativa dos custos dos materiais de instalações hidrossanitárias entre os anos de 2019 a 2023

Abstract

Since 2020, Brazil has suffered economic changes resulting from SARR-COV 2 (COVID-19) and the war in Ukraine, in which several areas were affected, generating an increase in product prices, including in civil construction, especially in its inputs, which had significant increases. In view of this, this research aims to analyze the increase in the costs of materials for hydro-sanitary installations, aiming to obtain the quantification of the increase in these materials. Based on the National Construction Cost Index (INCC) and the National System for Research on Costs and Indices of Civil Construction (SINAPI), which with their methodological particularities carry out studies on civil construction. This research carried out a comparative analysis on the costs of materials for water and sanitary installations in 2019 and 2023, through the survey of material quantities, in which the Excel application was used as a tool to budget the basic materials for water and sanitary installations, which aimed to verify whether the increases suffered by the materials changed the percentage that water and sanitary installations traditionally occupied in the total cost of the work, which was in the range of 11.2% to 12.1%. The results indicated that there was an increase of 57.23% in the costs of materials, increasing to 16.37% the percentage that water and sanitary facilities traditionally occupied in the total cost of the work. By accounting for this difference of 16.37%, new values were found for the reprisal of materials.
