ESTUDO SOBRE A PRODUTIVIDADE DA MÃO DE OBRA NA EXECUÇÃO DE ALVENARIA ESTRUTURAL COM BLOCOS DE CONCRETO

Abstract

With intense interest in Brazil's economy, the Construction Industry (CCI) is considered the country's largest industry, however, is characterized by a strong technological deficiency, and have low rates of hand labor productivity. Factors such as the intensification of the dispute between the companies of the ICC, and better conditions for customers require the provision of quality services, have contributed to these companies provide better services, and invest in creating technologies that make its more dynamic performance and productive. This paper has been prepared following the methodological basis of the model proposed by Thomas Factors; Yiakoumis (1987) to analyze the collected productivity indicators "in loco". It was also examined possible factors that could affect productivity on the construction site and analyze the building system in structural masonry. To develop this study, daily withdrawals were made on the implementation of structural masonry Elevation service in a work located in Três Corações, in Minas Gerais, and then the data were compared to the indices published by Araújo (2000). To develop this study, daily surveys were made on the implementation of structural masonry Elevation service in a work located in Três Corações, in Minas Gerais, and then the data were compared to those published by Kurzawa (2006). Analyzing the results of this study, it was found that the work in question had RUP's indexes accumulated average of 2.06 Hh / m² in structural masonry lift service. Far above the value recommended by Araújo (2000) in the order of 1.30 Hh / m². Such indices reflected in a delay in the construction schedule, which was mainly explained by a high occurrence of shortages of workers and poor disposal of materials at the construction site.
