Análise da viabilidade técnica e econômica do sistema construtivo de concreto PVC comparado ao sistema tradicional: caso de uma creche em Jardim /CE

Abstract

The Brazilian construction industry, however, still largely relies on traditional construction systems, with buildings made of simple reinforced concrete structures and masonry or common rammed earth walls. About 88.6% of Brazilian buildings (65.7 million houses) were built using traditional methods. Nevertheless, the pursuit of development and the country’s social needs have encouraged the government to invest in alternative construction systems such as Light Steel Frame, Container, Wood Frame, Structural Masonry, Metal Structures, and Off-site Construction. These alternative systems are mainly used in social projects such as affordable housing, daycare centers, schools, and health posts. Several municipalities in southern Ceará have been adopting the Concrete PVC construction system for building schools and daycare centers due to its rapid completion. The system consists of assembling modular PVC panels that are later filled with concrete and steel, with the PVC panels themselves serving as the wall finishing element. This study aims to understand the technical standards, materials used, construction process, and the advantages and disadvantages of the Concrete PVC system, and through a case study, to determine the cost, construction time, and feasibility of a public daycare center in the city of Jardim-CE built using the Concrete PVC system, compared to its construction using the traditional system with reinforced concrete structure and masonry infill walls. The study concluded that the Concrete PVC system is 4.4 times faster but 2.04 times more expensive than the traditional method. Despite the higher cost, it proved to be viable for public works, such as the daycare center analyzed, as it allows for rapid construction that effectively meets the population’s needs in a shorter period of time.
