Production- Permision to film on the roof

To be able to film on the roof i had to get permission from a few people. I had to go to on of the heads of the college, i was able to get permission from Paul the Deputy head of the college. I then had to get permission from Steve Hanson who is in charge of our college facilities. He said i would be able to if i get permission from my teacher and that they would be on the roof with us. I also had to write up a risk assessment and give that in to them.
