4D CAD 기반의 철골공사 위험예측시스템에 관한 연구

Until now, in most of construction proiect,s the analysis of danger factors has been implemented with contractor's and owner's experience or intuition. But Construction Activity is not simple, but complicated. In planning step, unexpected accidents must be considered and regulation for preventing them must be established. Most construction accidents occurs unexpectedly and even expected accidents have possibilities to break out a sequential accidents. So in this study we would suggest the idea of danger prediction system based on 4D CAD in construction.
