Abstract
En 中文
• Grid-based spatial analysis quantifies activity complexity-duration relationships in construction. • CV-based activity classification architecture (ViTPoseActivity) achieves 97% detection accuracy. • BIM-derived complexity metrics enable localized correlation analysis for proactive planning. • Analysis of 1,900+ labor hours in rebar installation confirms measurable activity complexity-duration correlation.
