Análise da produtividade da mão de obra em execução de formas de viga e concretagem de lajes e vigas de concreto armado

Abstract

This work evaluates labor productivity in beams formwork and in beams and slabs pouring concrete in reinforced concrete residential constructions. The methods used are daily productivity measurements of the workers, the consequent services monitoring and production data collect besides analyzing the everyday problems of the construction. Thus, it is possible to compute the Unitary Production Ratio (UPR), the production indicator used, and, so, to describe the true factors that influence the productivity, suggesting guidelines in order to improve the productive situation of the workers. The indicators found for formwork activity show high productivity and for pouring concrete most of them show low productivity. About pouring concrete, the delays of the concrete-mixer truck, styrofoam break and hose clogging contributed for the low production.
