Análise da produtividade de mão de obra na construção civil: estudo em obras de pequeno porte na cidade de Crateús-CE

Abstract

The construction industry (CI) is one of the most important for the Brazilian economy, due to the large productive arrangement that is formed around a construction project that implies in jobs generation, specially for less educated workers, hardly absorbed in other economic sectors. However, the CI is marked by low quality and productivity, especially in small works, whether performed by Small Enterprises (SE) or in self-construction regime of works - the latter characterized by high informality. Thus, despite the prolific scientific production in this research matter, studies are mainly focused on larger works. There is a lack of information about productivity for small works. Thus, this work aimed to analyzes the productivity indicators in small works. To that, three case studies in small works in the city of Crateús were performed. The city was chosen due to the lack of systematized information about the construction sector, despite of its great activity. The processes analyzed were the (1) masonry, (2) slab structure, (3) slab concrete, (4) wood roofing, (5) roofing, (6) wall cladding and ceiling and (7) subfloor. This allows characterizing the construction process, obtaining the study indexes and comparing them with the literature. In addition, it was possible to analyze the factors that impacted the productivity. It is worthy to notice that the availability of SINAPI data for small works shows more adequate than SEINFRA. The SINAPI data was closer to the data collected in the study. This research can contribute significantly to improving the construction management in small works performed by local agents - or others regions of the country, which work in construction, as it presents a characterization of those closest to reality as well as expanding on the empirical analyzes of the construction management literature.
