Viabilidade do uso de estrutura pré-moldada em edificações residenciais de 5 pavimentos: estudo de caso

Abstract

Considering that structures built conventionally with reinforced concrete may present schedule problems due to climatic factors and various parameters involved in their design. On the other hand, prefabricated structures have shown promise and are constantly growing in the market. They offer agility, more accurate schedules and incorporate new technologies in the execution of parts, such as pillars, beams and slabs, which has attracted investments and development of this construction method. However, the construction of residential buildings in prefabricated structures has not yet received much attention due to cost issues, lack of skilled labor and transportation. In this context, this course conclusion work aims to study the feasibility of constructing a building with 5 floors using a reinforced concrete structure in loco, comparing it with data from the same building executed in precast, mainly in relation to the schedule and the costs between the two methods. For this, a methodology is adopted that involves the collection of data on costs and schedules of the two constructive methods referring to the structure, which is one of the main factors to be considered in the study of undertakings such as residential buildings. The results obtained are of great relevance for comparison and for future research related to the subject, allowing to conclude that the choice of construction method is essential for the investor and will depend on several factors, including financial aspects, feasibility of using precast structures and the specific application of the project. The civil construction industry is increasingly evolving towards fast and quality works and this evolution is reflected in the choice of the most appropriate construction method for each project.
