Análise comparativa entre fontes de preços utilizadas na elaboração de orçamento de obras públicas para o serviço de fornecimento e instalação de condutores elétricos #2,5mm²

Abstract

The present research is a comparative analysis between some price lists used as price reference in the elaboration of public works budgets. For this analysis it was selected the installation service of electrical wire #2.5mm² PVC 750V. Unit costs compositions were taken from 06 (six) price reference systems. Initially, it made a comparison between them to see which one is best suited according to requirements taken from the literature. In this theoretical analysis, the SINAPI system was the best agreed with the literature. In a second analysis were made time measurements in three works whose data were used to construct a unit cost composition using real data. This composition was confronted with the unit cost compositions of reference systems and indicated evidence that the reference systems consider higher labor rates than necessary, and the SINAPI system was the best agreed with the comparison results.
