SG <br />Consent Item <br />Indian River County, Florida <br />Department of Utility Services <br />Board Memorandum <br />Date: September 29, 2023 <br />To: Indian River County Board of County Commissioners <br />Through: John A. Titkanich, Jr., County Administrator <br />Sean C. Lieske, Director of Utility Services <br />From: Howard G. Richards, PE, Manager - Capital Projects <br />Prepared By: Michael C. Loveday, Wastewater Superintendent <br />Subject: Atkins North America, Inc. Work Order No.1- West Regional Wastewater Treatment <br />Facility Clarifiers 1 and 2 Rehabilitation <br />Descriptions and Conditions: <br />Indian River County Department of Utility Services (IRCDUS) owns and operates the West Regional <br />Wastewater Treatment Facility (WRWWTF), which has a six (6) million gallons per day (MGD) annual average <br />daily flow design capacity. The WRWWTF is an advanced activated sludge wastewater treatment facility that <br />has undergone multiple expansions, with the current iteration being phase three. <br />After the last expansion in 2012, two (2) of the four (4) secondary clarifiers were not necessary to meet <br />capacity requirements. As such, Clarifiers 1 and 2 were taken offline (but not decommissioned). Current and <br />anticipated future growth in the west service area has brought about the need for additional secondary <br />clarifier capacity at the WRWWTF. Accordingly, both Clarifiers 1 and 2 will need to be returned to operation. <br />Clarifiers 1 and 2 are now in need of rehabilitation due to the overall condition of the equipment. Since this <br />treatment equipment is essential for effective operation of the facility and to meet capacity, IRCDUS desires <br />to undertake the rehabilitation project of Clarifiers 1 and 2 to ensure continued reliable operation of the <br />facility. <br />Analysis: <br />At the request of IRCDUS staff, Atkins North America, Inc. (Atkins) prepared the attached Work Order (WO) <br />No. 1 pursuant to the Continuing Contract Agreement for Consulting Engineering Services dated May 2, 2023, <br />to provide technical services for replacement of the mechanisms for Clarifiers 1 and 2, including engineering <br />assistance, Request for Proposal (RFP) development, bidding support, and construction management services <br />during construction (SDC). The estimated total engineering fee, including labor and expenses associated with <br />WO No. 1 work, is not to exceed $222,313.70. <br />33 <br />
