Bahria phase 8 sector f2 rawalpindi

I have few questions about latest updates regarding f2 sector,is this area away from takht pari disputed/illegal area, is this sector fully developed and is it good location to buy plot?
Many thanks

F2 lies in the area where there is alot of filling.even F3 have similar filling issue. I suggest to avoid F2/F3 or conduct prior soil test.

In Phase 8 which are the best sectors to buy a plot without any issues(filling etc.)
