• Creating a virtual construction site with 3DCG to visualize work before it begins

  Introduction video: GEN-VIR Construction Simulator

  GEN-VIR is a construction simulation technology that uses 3DCG to build a virtual construction site, where virtual workers’ movements can be reproduced to support construction planning. It allows users to adjust and evaluate variables such as work sequence, number of workers, equipment and material placement, and coordination with other tasks—all while observing the impact of those changes. This enables detailed pre-construction planning that also considers safety and worker fatigue, contributing to safer construction sites and improved productivity.

• Visualizing tasks, muscle fatigue, and risks through data analysis features

  

  Overview of GEN-VIR

  The work analysis feature allows users to identify when and where inefficiencies occur, enabling concrete planning for workflow, tasks, assignments, and crew sizes.
  The muscle fatigue analysis feature calculates physical load based on each worker’s posture data and inputs it into a fatigue model along with working time, allowing the system to estimate changes in remaining muscle strength for different body parts (e.g., arms, lower back).
  The risk analysis feature visualizes exposure records to hazards, helping identify when and how severely workers are exposed to risks, and supports proactive communication and safety planning.

• Using simulation results on-site

  Simulation results can be shared on-site as animation videos and analysis reports. They can be used to confirm work schedules with clients and serve as briefing materials for workers before starting tasks.
