Construção modular: análise de custo e prazo de execução em uma obra

Abstract

This paper presents a comparison between the cost and execution time of a commercial space using two construction systems: the conventional system, with reinforced concrete structure and ceramic brick masonry sealing, and a modular system with galvanized steel structure and glass fiber reinforced concrete walls. The costs of the conventional project were calculated based on the SINAPI table, while the costs of the modular project were provided by a company specialized in modular buildings. The execution time of the conventional system was calculated using the productivity coefficients of the budget through the PERT/CPM method. The deadline for the modular project was defined by the company responsible for the modular execution. The results indicated that the modular system is more agile, presenting a deadline approximately 8 times shorter than the execution of the same work through the conventional system. However, the modular system presented a cost approximately 2.5 times higher than the conventional system.
