Métodos executivos modulares: impacto no planejamento de obras verticais

Abstract

This study presents a comparative analysis between traditional construction methods (cast-in-place concrete and conventional masonry) and modularized solutions (precast concrete and drywall) applied to a multifamily residential building. The methodology includes budget assessment, productivity analysis per worker, and impacts on the construction schedule for concrete structure and masonry/partitioning services. Results showed that adopting precast systems reduced structural costs by up to 18.76% and shortened the schedule by 53 days. Meanwhile, drywall implementation provided direct savings exceeding R$ 1.2 million and significant productivity gains in ceiling system execution. The study concludes that modularization is technically feasible and economically advantageous, especially in highly repetitive projects, reinforcing its role as a strategic solution to enhance the performance of the construction sector in Brazil.
