Public Safety Radio Tower Cabling Reconfiguration

The Contractor is responsible for: 1. Designing a new pathway for a cable support structure to traverse the span from the PST to the hallway inside of the underground facility. This will include a lightning protection system that will replace the current lightning protection panel that is inside of the facility. The new lightning protection system must be located within the bulkhead or wooden structure and must be weather proof. 2. Installing the new antenna cabling support structure that spans from the PST to a lightning arrestor support structure. 3. Installing lightning arrestors (Quantity of 32) and lighting protection mounting structure. The lightning arrestors and cables must be installed in a manner that allows for maintenance access. FEMA prefers all RF connections coming off of the tower to be installed as 7/16 DIN, unless the contractor has a superior performing recommendation. 4. Installing cable support structure from lightning protection system, into the bulkhead, and terminating at the metal pipe passthrough entrance. 5. Installing antenna cable connection passthroughs in the faraday cage wall located inside the internal hallway. Passthrough location on the wall will be designated by FEMA. FEMA prefers all of these pass throughs to be installed as 7/16 DIN. 6. Pulling all telecommunications cables from the additional towers on site out of the metal conduit and bulkhead. The cables will then be terminated at the lightning protection system. If there are cables cannot be pulled back, then they will require lightning protection and grounding to be added inside of the bulkhead for those inline. This is to ensure all telecommunications cabling is terminated with some type of lightning protection system prior to entering the underground facility (with the excemption for equipment installed in or on the wooden shed). 7. Installing jumpers from the base of the tower to the lightning arrestors for 7/8” cables. Cutting and installing new connectors on all other telecommunications cabling to terminate at the lightning arrestors. Install new jumpers from the lightning arrestors to the internal hallway (one cable each for all lightning arrestors). 8. Grounding all new hardware and cabling as recommended in Motorola R56. 9. Weather proofing all connections and hardware installed by the Contractor as required. 10. If the antenna cabling support structure connects directly to the tower, a proposed structural analysis will be provided by the Contractor prior to work start for FEMA approval. The current structural analysis will be provided to the Contractor as a baseline.
