Análise comparativa de custos de sistemas construtivos de alvenaria estrutural e parede de concreto

Abstract

In recent years there has been a great increase in investments in construction, many ventures have arisen and there are still many to be built. With this, many companies, in the quest for the highest possible return on investment, are faced with the choice of the ideal construction system for their interests. Thus, this research seeks to present the best solution from the economic point of view with a comparative feasibility study between structural masonry and concrete walls, taking as reference a case study of an enterprise in Aparecida de Goiânia - GO, with 196 housing units. The data presented refer to the characteristics of each executive method, as well as its advantages and disadvantages. The study was based on a comparison of costs of popular housing budgeted in each of the aforementioned constructive methods, summarized in a table with the purpose of proving the executive and financial feasibility of one of the methods. In the study in question the method of concrete walls is advantageous when used in projects with large volumes and high repetitiveness in their processes, becoming about 16.5% cheaper when compared to the structural masonry system.
