DIGITALIZATION OF CONSTRUCTION SAFETY: SKETCHUP-BASED 3D VISUALIZATION FOR PEDESTRIAN BRIDGE WORK METHODS.

Abstract

The implementation of safe work methods in pedestrian bridge (JPO) construction is often hindered by the use of non-interactive, conventional training media, leading to comprehension gaps and safety risks. This community service activity aimed to address this by utilizing SketchUp-based 3D visualization as a medium for socializing and training safe work methods. The activity, conducted in partnership with PT. PP (Persero) for the Tower B project at RSK Dharmais, involved 30 workers and supervisors through interactive training sessions and 3D simulation workshops. Evaluation was carried out via pre- and post-knowledge questionnaires, direct observation, and follow-up interviews. The outcomes demonstrated an 85% increase in understanding of safety procedures, a 75% improvement in hazard identification capabilities, and a 70% reduction in work method implementation errors, confirming the effectiveness of 3D visualization as an engaging training tool.
