i asked my contractor to do 7 inch coring for kitchen hood ducting, end up he leave a gap of 5 inch from the ceiling then + 7 inch coring,

so my plaster ceiling have to be 14inch which is out from my plan to keep the plaster ceiling height at 10 inch.

why did he leave a 5 inch from the ceiling? due to machine the contractor used or for safety ?

my contractor didn't explain much, he just said it was done according to coring expert advice.

Should not core an RC wall, but presumably he did it due to beam location.
