Construction Workers’ Behavior Assessment Using 3D Visualization and Fuzzy Logic Method
Publication: ICCREM 2020: Intelligent Construction and Sustainable Buildings
ABSTRACT
Construction workers’ unsafe behaviors account for a large percentage of occupational injuries in construction industries. These inappropriate behaviors are commonly identified as having high ergonomic risk resulting from awkward postures, repetitive tasks, and excessive manual material handling. To facilitate ergonomic risk identification and the subsequent mitigation, an enhanced version of automated post-3D visualization ergonomic analysis has been developed with the integration of a proposed fuzzy logic-based joint-level ergonomic risk assessment methodology for work modification and workplace design. The proposed method aims to accurately and efficiently assess the construction workers’ behaviors for the development of ergonomic-centric workplace design prior to real-world implementation. It is validated through an experiment involving a lifting task using an optical marker-based motion capture system. With the integrated fuzzy logic method, the results of the enhanced system illustrate a higher level of accuracy and reliability through three levels of comparison and sensitivity analysis. By using the developed method, users can easily and quickly evaluate workers’ behaviors and consequently accomplish their desired ergonomic-centric workplace design to prevent and reduce work-related musculoskeletal disorders in construction.
