GOC6535434 CS - GOC6535434 CS Lightning Protection System Repairs

Items that need to be addressed include but are not limited to (Consultant to verify all requirements): 1. A structure of this size requires four additional down conductors. 2. Existing screws used to secure the cable holders, air termins, the Uni-Strut, etc should be replaced with new stainless-steel screws. 3. Perimeter air terminals on the main roof are spaced too far apart and additional terminals are required. 4. Air terminals either have not been installed on the penthouse roof edges or are spaced too far apart. 5. Air terminals have not been installed on the critical strike point areas. Numerous rooftop mechanical units are unprotected. 6. Rooftop stack required additional air terminals, a second path to ground, cable holders and a bonding connection. The existing lightning protection materials should be removed due to corrosion concerns. The guard raid requires air terminals and bonding connections. 7. New guard rails require air terminals and bonding connections. 8. The air terminal adjacent to the north antenna is not the required 10" above the antenna and a bonding connection is also required. 9. Primary conductors shall be coursed in a horizontal or downward path to the ground or shall rise at no more than 1/4 slope to connections to ground. 10. The north west and north east cameras are not protected by the adjacent air terminal. The air terminal needs to be within 24" of the outside edge of the camera as well as 10" above the camera. 11. The antennas are presently used to provide a zone of protection for certain areas of the structure. Current lightning protection standards do not allow roof top antennas to create zones of protection. Air terminals and conductors should be added to the affected areas. The antenna towers shall be bonded to the system. 12. The cooling tower requires air terminals and full-size bonding connections. 13. There are numerous cross-roof intercepting conductors that have been altered by foot traffic on the main roof. The conductors should be straightened, the cable holders should be adhered directly to the roof, cable holder tabs should be folded over the conductors and caution flags and/or tape should be affixed to the conductors in these areas. 14. Numerous conductor bends have been altered "No bend of a conductor shall form an included angle of less than 90 degrees or have a radius of bend less than 8 inches (203mm). 15. Due to the presence of rubber gaskets, bonding connections shall be installed on the air conditioning units as well as the support framework. 16. Bonding connection has been removed from the drain and cable holders are damaged and need repair. 17. New antenna requires an air terminal and a bonding connection. 18. Parallel splicer has been damaged and does not provide a secure connection between the down conductor and the perimeter conductor. 19. Repair/replace broken air terminal on the west main roof. 20. Exterior staircase requires bonding connections.
