Improving Effectiveness of Safety Training at Construction Worksite Using 3D BIM Simulation

Examples of 3D modeling views and training contents.

Examples of 3D modeling views		Training contents
		The 3D simulation demonstrates that a safety platform must be used when alighting from the hoist, as there is a fall hazard due to the opening between the hoist and the floor
		The 3D simulation emphasizes the need to wear helmets to prevent injuries due to falling objects and to wear the safety belts to prevent fall accidents when working in the gangform.
		The 3D simulation informs about the hazard of impalement from protruding ends of steel rebar or concrete form pin and directs the use of PPE and rebars caps in the case of moving to the rooftop through the narrow stair room. The 3D simulation locates the form fixing pins and rebar specific to the stair room in the actual corresponding building, contributing to the worker’s identifying the hazards in the exact location
		The 3D simulation shows that there is a fall hazard due to the openings in elevator rooms or the openings for carrying materials and indicates the need of opening cover and warning sign installation. The exact size and location of the openings are reflected in the simulation, demonstrating the precautions in the actual worksite
		The 3D simulation shows that (1) standard safety guardrail must be installed when working at heights greater than 10 feet in form and rebar installation work and that (2) the workers must wear the safety belts to prevent themselves from fall accidents in high place work
		The 3D simulation indicates that working under lifted materials is prohibited in top slab and that the cranes must load the materials in double-legged sling. Also, training reflects the movement radius of the tower crane in actual construction site indicating the precautions in the pertaining area
