Análise de índices de produtividade de uma obra de médio porte

Abstract

The construction sector is in constant growth, and as a result of that, the search for higher standards, lower costs and smaller execution times grows proportionately. Labor productivity in the construction industry is a factor of fundamental importance, since it impacts directly the time and cost of work. This work aims to analyse some of the productivity indexes of a construction work in the city of Uberlândia - MG, comparing values practiced by the construction firm and those available in the literature, in order to identify possible divergences and opportunities for improvements. For this purpose, field measurements of the Unit Production Rate (UPR) were done based on the construction diaries. UPRs measurements of the following activities were taken: cutting services, folding and frame assembly services, cutting off steel, masonry, plastering and interlocking floors lay off. These results were analysed and also compared with the databases of Budgeting Price Composition Table (BPCT) and the National System of Research on Costs and Indices of Civil Construction (NSRCICC). Some results obtained for the UPRs were close to those used by the construction company in during its planning processes, while others showed considerable discrepancies. Probably one of the main causes for discrepancies was the layout of the construction site and the logistics for transporting the materials.
