ANÁLISE COMPARATIVA DOS CUSTOS DIRETOS ENTRE UMA ESTRUTURA INDEPENDENTE EM CONCRETO ARMADO E OUTRA EM ALVENARIA ESTRUTURAL DE UMA EDIFICAÇÃO RESIDENCIAL MULTIFAMILIAR

Abstract

This case study aims to economically compare two of the most widespread construction techniques in Brazil and in the world: structural masonry and reinforced concrete. Through two structural projects originating from the same architecture, the inputs were quantified and budgets were elaborated to verify which system would be more economical in the execution of the structure and the fence. The growing competitiveness in the civil construction sector makes good planning indispensable for construction companies, developers and the like who are looking for success in the market. The choice of the structural model that best suits the enterprise in question is of fundamental importance in this respect. Initially, a brief bibliographic review of the two systems is presented, containing a brief history, presentation of its main components, as well as advantages and disadvantages in the adoption of each of them. Then the structural masonry project provided by the construction company responsible for the execution of the project and the project in an independent reinforced concrete structure developed in this work by the author are presented. At the end, the quantity of inputs are calculated to develop and compare the budgets of the two models. The results presented can serve as an initial parameter for defining the constructive technique to be used in projects similar to the one addressed.
