Análise comparativa entre o previsto e o realizado de coeficientes de consumo de mão de obra

Abstract

The objective of this work is to analyze the sizing and productivity rates predicted and carried out in reinforced concrete sanitation works in different cities in Brazil, comparing the values practiced by the construction company and those available in the literature. The research was conducted through case studies in already executed sanitation works, collecting data on the Unitary Production Ratio (UPR) for the services of framing, assembly of formwork and concreting. Obtaining the information was carried out through the analysis of Daily Works Reports, in addition to interviews with the professionals responsible for the works and for completing the reports in question. The results found were analyzed and compared with the databases of the National System of Research of Civil Construction Costs and Indexes (SINAPI) and the Reference Costs System for Works (SICRO). At the end of the work, it was possible to verify that the use of the construction company's own indicators assertively reflects what was done when seen by the Cumulative RUP, but they differ greatly when analyzed by the individual RUP of the services, showing a possible failure in data collection. It is expected that this study will contribute to the improvement of sizing and productivity management practices in reinforced concrete infrastructure works, resulting in benefits both for companies in the sector and for society, through the improvement of the quality and efficiency of these works essential for national development.
