The paths of the cable trunks above the roofs - Cable routes need to steer clear of electrical light fixtures or additional resources of EMI (Electro Magnetic Interference). Preserve wire routes in accessible regions of the roof for potential wire runs and simple maintenance. All pathways must be run above hallways on significant 90 degree turns, and cables enter individual areas. Put in a firestop sleeve for all penetrations of a fire-wall. Be cautious when dragging wires in order not to extend them. This can create a failure when testing. DON'T wrap wires to sprinkler pipes or limit hangers. They should be tied at least every 5' on horizontal runs, and even more on straight runs. J-hook supports should be secured towards the concrete patio above. Use velcro wraps every 5'or-so when completed managing wire to offer your wire programs a terrific looking finish.
