Exhibit 1 — Proposal <br /> Amendment No. 2 <br /> To <br /> Work Order No. 5 <br /> Scope of Services <br /> Indian River County <br /> Department of Utility Services <br /> Additional Design Services for the West Regional WWTF <br /> General <br /> PBS&J has been providing design services on the West Region WWTF for Indian River County Department of Utility <br /> Services (the County). During the course of the design, additional design services have been requested by the <br /> County to evaluate and design the replacement of the existing reclaimed water pumps located across the ribs . <br /> PBS&J would provide the additional design and associated construction services (shop drawing reviews, RFI , site <br /> visits) according to the following scope of services with County staffs written approval. <br /> Scope of Work <br /> The scope of services shall include the following specific items: <br /> 1 . Evaluate the replacement of existing pumps in its original location vs. down stream of intermediate pump <br /> station at the plant site. The evaluation will be summarized in a memorandum format. The evaluation will <br /> include cost and non-cost factors. <br /> 2. Two (2) pumps (with one as standby) will be included in the design to provide a total pumping capacity of 2.0 <br /> MGD. PBS&J will calculate the pump discharge head based on the existing pipe between the two plants. <br /> County will provide the existing system information. <br /> 3. Incorporate the design of the pump control system in the plant SCADA system and design its interface with <br /> the remote storage tank located at the north plant. It is envisioned that a motorized valve at the tank will <br /> control the water flow into the remote tank. Pump control shall be based on the discharge pressure and the <br /> remote motorized valve status. Valve position shall be interlocked with the pump operation to coordinate <br /> start/stop and to avoid water hammer in the transmission line. <br /> 4. Based on the effluent piping hydraulic evaluation , plant site piping modifications shall be identified and <br /> designed. <br /> 5. Structural modification and/or additions to the intermediate pump station will be designed to incorporate the <br /> new reuse pumps. <br /> 6 . In the plant site location option, the reclaimed water pump station discharge pipe shall be extended to down <br /> stream side of the existing reclaimed water pump. The pipeline drawing shall be in plan view only and shall <br /> be shown on an aerial base map to 1 " = 40' scale. No new surveying is deemed necessary or included in <br /> the scope. <br /> 7. The pump station and reuse main extension design shall be incorporated in the current construction project <br /> underway at the West Regional WWTP via a change order. <br /> 8. According to conversation with FDEP no new permit or permit modification are anticipated or included in the <br /> scope. A letter of notification will be sent to FDEP describing the changes. <br /> The work outlined above will be completed in conjunction to the construction of the West Region WWTF . <br /> Schedule <br /> The estimated time frame for completion of services from the approval of this Work Order is as <br /> follows : <br /> Page 1 of 2 <br /> LWWR JttnIR('.
