| Abstract |
Modular construction, which combines off-site prefabrication with on-site assembly, improves speed and quality but introduces unique safety
risks during installation. These risks include high-altitude work, simultaneous operations, and heavy lifting, which differ from those in
conventional construction. This study seeks to enhance safety management in modular projects by identifying key risks and proposing
process-based countermeasures. Field observations were conducted at a modular hospital project on Hanyang University’s ERICA campus.
Safety issues were categorized by construction phase: substructure, unloading, placement, connection, and finishing. A safety protocol list was
developed and refined using expert feedback through the Analytic Hierarchy Process (AHP). Twenty-two construction professionals participated
in the AHP survey, which used a fine-grained scale (1.0 to 2.0) to improve accuracy and minimize bias. The results identified fall protection
during modular lifting and placement as the highest priority, followed by fire risks from welding and spatial constraints during finishing.
Based on these findings, the study recommends mandatory lifeline systems, deployment of signal personnel, stabilization devices, and
enhanced fire safety measures. These outcomes provide phase-specific safety strategies and support the advancement of industry guidelines and
training systems tailored to modular construction. |
