Specifications include, but are not limited to: III. Scope of Work The services below must be included in the scope of work of any submitted proposal, and must conform with the project specifications provided herein: 1. Design, construct, and deliver a 180 ft. self-supporting communicationstower. 2. Install the tower on a concrete foundation. 3. Install overhead PVC conduit from communications shack to tower. 4. Move existing site antennas to the new tower and install with coax runs. 5. Deliver as-built drawings to County upon completion. IV. Project Specifications Work performed must conform to the following project specifications: 1. The tower should be left unpainted and constructed of dull, galvanizedsteel. 2. The tower will be constructed at least 20 feet westward of the current shelter building. County will confirm tower location in person prior to commencement of construction activities. 3. The GPS coordinates of the tower site is 31օ 31’02” North, 111օ 01’35” West. 4. Prior to construction or installation, engineered drawings of the tower will be required to be submitted to Santa Cruz County for review/approval. Plans will be stamped by a licensed engineer. Engineering design should ensure that the tower complies with current structural and safety specifications and design standards. 5. Contractor shall design, supply, and construct all necessary components for a fully functional standard tower base foundation/anchor system/grounding system, compliant with all applicable laws, codes, and standards. Contractor shall supply all equipment necessary to transport and construct the foundation(s)/anchor(s)/grounding(s) according to all applicable laws, codes, and standards. 6. The tower foundation will be constructed with a sloped ground level surface that ensures positive drainage. 7. The design, installation, and loading shall account for wind speed and loads for a tower installation at the proposed site. The tower must conform to the tower manufacturer’s foundation and erection criteria. 8. The tower necessitates the installation of best-practice mounting hardware to support existing microwave, Blue Stick type antennas and dishes that are on the current tower. 9. The tower shall be equipped with a coax mounting hardware system sufficient to provide proper support for the existing antennas and associated microwave systems. 10. The tower installation shall comply with interference standards for lightning grounding. The grounding system shall meet the more restrictive requirements of this specification and the most current referenced standards. 11. A safety-climb system shall be installed on the tower allowing a climber to remain connected to the safety-climb cable for the entire height of the tower. The safety climb cable shall be to code and constructed from a corrosion resistant material and shall comply with the state requirements. The tower installation contractor should determine the appropriate side of tower for the safety-climbing system. 12. All equipment mounted on the tower shall be handled and installed in accordance with the manufacturer’s recommendations to prevent damage to the equipment or the tower. 13. Contractor shall design, supply, and erect all necessary equipment for a fully functional overhead cable ladder extending from the shelter building to the nearest tower leg. Contractor shall supply all equipment necessary to transport and erect the cable ladder and foundation(s) according to all applicable laws, codes, and standards. 14. Contractor shall install and/or relocate all site antennas to the new tower and run/connect all associated coax. 15. Contractor shall remove all tower erection and related debris upon completion of the tower and prior to final inspection. 16. Native soils and rocks to be back filled in the construction area to preserve naturallooking surroundings. 17. When ground disturbing activities occur during construction, Contractor will monitor ground disturbance and if any potential archeological resources are discovered, will immediately cease construction in that area and notify County. 18. Three (3) sets of as-built drawings shall be delivered to Santa Cruz County within fourteen (14) working days of completion of the tower. As-built drawings shall also be submitted in a legible electronic PDF format. 19. Final payment is subject to County project inspection and acceptance.
