EXHIBIT #A PROJECT ID 13.23.538 Indian River County Department of Utility Services Amendment No. 1 to Work Order No. 6 Carrier Equipment Corral versus Temporary Relocation Cost Comparison PROJECT UNDERSTANDING Indian River County Department of Utility Services (IRCDUS) owns and operates the Gifford Elevated Water Tank located at 4690 28d' Ct, Vero Beach, FL 32967. The tank is currently out of service and is instead used to carry telecommunication equipment. The tank was structurally evaluated under the current scope of work to determine what improvements would be necessary to support additional carriers on the tank. The structural improvements identified are currently under construction. Kimley-Horn also identified the need to sandblast and recoat the entire elevated storage tank. This would require relocating the carrier equipment. The equipment could either be relocated to a temporary telecommunication tower during the recoating process or the equipment could be permanently relocated to a corral at the top of the tank. IRCDUS has requested an amendment to the current contract with Kimley-Horn to evaluate the cost difference between the design and construction of a permanent corral on the top of the elevated tank to house the carrier equipment versus relocating the equipment to a temporary tower for the upcoming sandblasting and recoating of the elevated tank. SCOPE OF SERVICES Task 1 (No changes): Structural Analysis Report Task 2 (No changes): Structural Analysis Report w/ Modifications Task 3 (No changes): Modification Design Drawings Task 4 (No changes): Bidding Assistance Task 5 (Amended): Construction Phase Assistance Consultant will prepare a class 5 opinion of probable cost to compare the engineering and construction costs associated with (2) potential scenarios. Scenario I will include the design and construction of a top -mounted corral. Scenario 2 will include the engineering and construction costs to provide a temporary telecommunication structure for the carriers to relocate their equipment off of the water tank structure during the forthcoming sand -blasting operations. Scenario 2 will also include estimates to physically relocate the carriers to the temporary structure, and back to the water tank once coating operations have concluded. Task 5 (Amended): Deliverable Consultant will submit one class 5 opinion of probable cost for each of the two scenarios in PDF format. Consultant will provide a summary by email of their recommendation to IRC for the next phase of improvements at the Gifford Elevated Tank.
