Through Building Information Modeling (BIM), accurate quantity takeoffs were obtained, enabling a detailed economic assessment of both construction methods. The results reveal significant differences between the analyzed systems. Although the Lightwall system presents higher material costs, its increased productivity and substantial reduction in labor demand resulted in an overall cost approximately 27.96% lower than that of conventional masonry. Furthermore, the execution time was considerably reduced, with a decrease of about 84.13%, highlighting the potential of the industrialized system in optimizing construction schedules. Based on these findings, the study indicates that the Lightwall system is an economically competitive alternative, particularly in scenarios that require faster construction processes. In this context, the research contributes to the discussion on the adoption of industrialized construction systems in Brazil, encouraging a broader perspective in decision-making within the construction sector.ptAttribution 3.0 BrazilEngenharia CivilSistemas construtivosEPSAlvenaria convencionalLightwallBIMConventional masonryCost analysisTrabalho de Conclusão de CursoENGENHARIAS::ENGENHARIA CIVIL
