ANÁLISE COMPARATIVA DE CUSTO ENTRE A LAJE NERVURADA E MACIÇA EM RIO VERDE - GO

Abstract

Much is discussed about the costs involved in the execution of a work. In spite of the many steps, thus bringing the execution methodology, the same methodology is made in both slabs. This work analyzes a large work, a residential building containing 25 (twenty-five) standard floors, with the objective of presenting the best slab execution methodology in the city of Rio Verde - GO, among the massive and ribbed slab. The direct costs between the selected materials (steel and concrete) were analyzed. With the quantity of materials necessary for the development of the work, taken from the structural projects, a quotation of the materials was made in the stores in the municipality, quoting three prices for each material and using the arithmetic mean between them. In this way, it was possible to predict which slab obtained the best cost. Among the results, the ribbed slab presented the lowest cost, in relation to the solid slab, gaining in the concrete economy, being the main responsible for the final cost. Even if the ribbed slab consumes more steel compared to solid slab, the final result was expressive. Thus, it was concluded that the ribbed slab presented savings regarding the analyzed materials steel and concrete. Finally, observing the savings generated only in one apartment, it is noted that the value was not significant, but when considering the 26 (twenty-six) floors, there is a savings of 74,468.42 reais.
