Estudo de caso: comparação entre construção convencional e construção modular na ampliação de uma escola

Abstract

The following work sought to analyze the application of modular construction with a metallic structure as a solution for expanding classrooms and make a comparison with conventional masonry construction, showing that modular construction was an alternative that provides a more agile work, as industrialization construction allows factory steps to be customized and the assembly processes reduce the number of elements compared to the same area built in masonry. Furthermore, the elimination of debris and the use of pre-sized materials minimize environmental impacts. One of the perceived difficulties of the modular construction system is related to the logistics of transporting the modules, as they require long trucks and considering the height of the truck and module, authorization is required for transit on certain highways. By monitoring the work in modular construction, the deadline for executing the stages was obtained and, together with the bid budget, a comparison was made with conventional construction for the same project, obtaining the conclusion that for the case analyzed modular construction work would be up to 50% faster without considering delays or contractual additions in conventional construction. When it comes to costs, modular construction was 51.4% more expensive than conventional construction, however, modular construction still proved to be advantageous for emergency constructions such as schools and hospitals.
