Análise dos índices de produtividade de mão de obra no serviço de armação em estruturas de concreto armado - lajes, vigas e pilares.

Abstract

The budgeting process used by small and mediumsized construction companies usually uses consumption indexes drawn from the Table of Price Compositions for Budgets (TCPO, by the abbreviation in Portuguese) in their cost compositions. These indexes are generally based on the characteristics of the construction companies operating in the South and Southeast regions of Brazil, as well as, on the natural resources available in these regions not covering construction techniques and the availability of labor, material and equipment from other regions. In this scenario, differences between the budgeted costs and the actual consumption at the construction site tend to appear in budgets elaborated in the other regions of the country. This research aims to present an analysis of labor productivity in the framework service in slabs, beams and pillars made of reinforced concrete comparing labor indexes collected in constructions at the city of Campina Grande PB, with those foreseen in TCPO 14. For the study, two constructions in the superstructure phase were chosen, then data about performed service and worked hours were collected making it possible to calculate the productivity and perform an analysis of labor costs. With field values, a comparison was made with the cost compositions present in TCPO 14 for the framework service. The results of this specific analysis indicate that the service performed at the construction site has a well superior productivity than those indicated in TCPO 14. It was concluded from this, that the companies studied are not suffering from labor losses in these services. However, if there is a greater investment in the measurement of productivity at the construction site, it is possible to obtain data, which more accurately portrays the reality of the work and the company, based on the indices of own labor, since a great variation was observed in relation to TCPO 14.
