Estudo de caso comparativo da viabilidade econômica dos métodos construtivos: alvenaria estrutural e parede de concreto integrado ao planejamento de obras

Abstract

The Brazilian civil construction has undergone significant expansion in search for meeting the needs to overcome the high habitation deficit and to promote the market. This way, companies of this sector search for new ways of productive and economic construction. The cast-in-place concrete wall and structural masonry systems are two examples of the alternatives that have gained ground in construction companies, since they are able to provide the building projects with speed and productivity. However, there is a lot to investigate and deepen about the mentioned systems, such as, even both promote speed and economy, which one is more economically practicable than the other? This is the focus of our work that consists in a case study of two building projects in one company. They are similar in their designs and amount of habitation units, but each one is performed under one of the approached systems. It is inferred the practicability of the constructive processes, especially in the concrete wall system, which provides economy as it reduces the time of execution and the cost of a long period of work. With regard to the final budget analysis of the projects, it was verified the importance of controlling and planning the construction work and the ways that those techniques contributed to a satisfactory final cost.
