Estudo do impacto do uso de materiais pré-fabricados e serviços terceirizados no custo final de uma obra

Abstract

The civil construction sector has sought in recent years the modernization of its processes. For this reason, the use of prefabricated materials and inputs is increasingly common and the hiring of outsourced labor in the execution of the tasks. Thus, the present work has proposed to study the impact of these new practices on the total cost of a construction, through comparative analysis. In this analysis, the design of a single-family housing was budgeted in two distinct ways. Firstly, the construction was considered as performed in a conventional way, with their respective services carried out on-site and with their own staff. To this was compared the execution of the construction with outsourced services and prefabricated materials. Overall, the second budget presented the highest value, with a cost of 0.93% higher than the first. However, some outsourced services and the use of prefabricated materials proved to be economically viable.
