National Highways Authority Of India [NHAI] — Inadequate measures for safety of people

At chandni chowk the bridge demolition work is in progress and the mountain stone is being drilled and removed without any safety barigating. Today, during my travel to office a stone got hit on my car and the window glass of my car was broken and the stone hit on my leg. The major shock got absorbed by the window glass which got broken and then the stone hit my leg. I have highlighted this issue to the site contractor and NHAI supervisor. They have assured me for compensating the damage. However, I wanted to raise an official complaint against NHAI for not having any safety measures implemented during the work. Had the stone hit me or any other person directly it would have caused a major and serious injury or even death as the stone was of significant size which was hit.
