Cables can serve as significant obstacles especially if they are not neatly bundled together and left to go all over the place. For that reason, the film contact also has to sign off on how the cables are arranged.
Film shoots may also necessitate the usage of special equipment such as cherry pickers, cranes, and jibs. Unsurprisingly, filmmakers cannot make use of those pieces of equipment without clearance from their film contact.
The cherry pickers, cranes, and jibs to be used must come with the proper documentation and they can only be operated by certified technicians.
There may also be times when highway inspections will have to be performed before cherry pickers, cranes, and jibs can be used.
