Análise da produtividade da mão de obra na execução de alvenaria racionalizada com utilização de argamassa industrializada – estudo de caso em edifício em João Pessoa

Abstract

The civil construction industry increasingly demands competitiveness and improvement of its executive techniques. One of the ways to do this is through the implementation of new technologies in the production process in order to optimize or even reformulate traditional services, by increasing productivity and providing cost reductions and increasing the company's competitiveness. The present work aims to analyze the labor productivity in the execution of a rationalized sealing masonry with the use of an industrialized settlement mortar, through a case study carried out in the construction of a multi-storey building, located in João Person in Paraíba. The work seeks to analyze the executive process of masonry, measuring the productivity of labor and analyzing the advantages and disadvantages of using industrialized mortar. In terms of productivity, the average value obtained was 5.67 m²/day, which, compared to another enterprise of the company where the rationalized masonry made use of conventional mortar, was considered low, however it is justified because it is a service with less than 10 weeks of execution, where it is expected that in the coming months, with repetition and continuity, productivity will tend to grow. As for the implantation of industrialized mortar, it is concluded that the investment proved to be advantageous when analyzing the logistical gains within the construction site: simplification of material storage, agility in the production of mortar and less mobilization for its transport. The major disadvantage of using industrialized mortar is its cost, which is high when compared to conventional mortar, but which can be compensated with greater labor productivity, in addition to the mentioned logistical benefits.
