Delhi Development Authority [DDA] — Cement spread in parking creating breathing problems for residents

This is with refernce to cement which has been spread all over parking in the name of repairing of parking lot.The cement flies and gets inside all the nearby flats making it very difficult for residents to breathe specially the elders as well small kids.
Lot of people are down with breathing issues and day by day its going from bad to worse.
I would request the relevant authorities to look into this matter and immediately do the repair work so the ash don't fly and make it difficult to survive people here
