Abstract
Factory based (modular and panelized) building methods have been applied to a high proportion of construction projects due to their reduced waste, limited environmental impact, and decreased cost and construction times. Redesigning the production process, facility layout, and material handling process can thus improve productivity and reduce costs for manufacturers. Virtual Reality (VR) is increasingly being used to investigate the best methods for balancing the flow of construction activities and optimizing resources to prevent costly on-site errors. This tool can be applied in planning and designing module systems in manufacturing production lines to promote healthy, safe, and productive working conditions by reducing workers' fatigue and injuries, and their associated costs. This paper identifies and quantifies work-related ergonomic hazards from residential construction floor panel framing activities, using the VR model of the construction process to replace onsite observation and an ergonomic assessment based on ErgoCheck, a comprehensive ergonomic rating and assessment framework. The VR model uses an internal timer for productivity (cycle time) assessment. The impact of the ergonomic interventions on work productivity is thus assessed and the results show the potential of ergonomic interventions in improving production line productivity through a reduction in idle and cycle time.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
