Produtividade em sistemas de vedação: estudo comparativo entre blocos cerâmico e de gesso

Abstract

The concept of productivity conquers, more and more, its space in the scope of the civil construction. The increasing competitiveness among companies in the industry requires quality in the final delivery of the product, with less time and cost. Therefore, the present work has the objective of analyzing, in terms of productivity, the internal sealing systems composed of ceramic blocks and gypsum blocks. The methodology adopted consists, firstly, in the use of an analytical method to obtain a numerical value for productivity obtained through the expression of the Unitary Ratio per Production (RUP), calculated from data collected in construction sites, where the results relate the time spent by a man to perform an arbitrary amount of production. Another method was the elaboration of physical flows, realized through the observation of sequences of tasks performed with the materials used (storage, transport, etc.), and mapping by means of symbols, allowing the visualization of the logistics of the same. The results indicate that the system composed of ceramic blocks has higher productivity in relation to the system composed of blocks of gypsum. Through observations and comparative analyzes of the characteristics and execution specificities of both sealing systems, it was possible to identify factors that influenced the results found, some of them being the complexity of the execution of gypsum block masonry in relation to the ceramic block and the lack of skilled labor in execution of masonry of gypsum blocks, since this is not a widespread system in the state of Goiás.
