Análise da produtividade e custos de insumos na alvenaria convencional: comparativo entre SINAPI e preços locais no mercado de Itaituba - PA

Abstract

The civil construction industry plays a crucial role in Brazil’s economic development, contributing significantly to GDP and job creation. However, the sector faces challenges such as low productivity, lack of qualification, high turnover, and inefficient management. The Unitary Production Ratio (RUP) is an important tool for analyzing productivity, and the use of the National System for Research on Costs and Indices of Civil Construction (SINAPI) facilitates budgeting. This study aims to analyze productivity and input costs in conventional masonry in Itaituba, in the state of Pará, comparing local prices with the values established by SINAPI. The study is important for improving the efficiency and sustainability of the construction industry in the region and contributing to the country’s development. The research adopted an exploratory, descriptive, and comparative approach of a qualitative nature, selecting three works for productivity analysis and data collection on inputs used in the conventional masonry stage. The results showed that daily productivity was higher than the average established by SINAPI, productivity indicators were raised to evaluate the performance of work teams in each work. The results indicated that the team from Work B was the most productive, achieving a daily RUP average of 0.61 Hh/m², while the team from Work C was the least productive, with a daily RUP average of 1.01 Hh/m². The team from Work A achieved a daily RUP average of 0.90 Hh/m². In addition, some factors that can affect labor productivity in conventional masonry were identified, such as the quality of materials used and the organization of the construction site. The comparative analysis of input prices showed variations in relation to SINAPI table values, highlighting the importance of considering local market prices in estimating and planning works. Analyzing these factors can help identify possible production problems and opportunities for improvement in process efficiency. Efficient productivity management is essential to reduce costs and execution time, as well as improve the quality of final products. The study contributes to the development of civil construction in the region and in the country as a whole, providing relevant information for improving efficiency and sustainability
