Okaloosa County BOCC — April 1, 2014 — Agenda

BOARD OF COUNTY COMMISSIONERS AGENDA REQUEST DATE: February 19, 2013 TO: Honorable Chairman and Members of the Board FROM: Jeff Littrell SUBJECT: Constantine Task Order 70 DEPARTMENT: Water and Sewer BCC DISTRICT: 1&5 STATEMENT OF ISSUE: The scope of services for this task order includes professional engineering and technical services required to design, permit, and manage the construction of a new 4.2 MGD sewer repumping station. The project includes installing a new repump station to allow OCWS to divert the flow from the old Niceville Valparaiso Regional WWTF and pump all of the wastewater received from the East County Sewer Service Area via the Meigs-Seminole Lift Station to the Arbennie Pritchett Water Reclamation Facility (APWRF). The Scope of Work for this task order has been developed and negotiated with Constantine Engineering per the terms of our Master Services Agreement to perform these services and requires approval by the Board of County Commissioners. Task Order 70 is attached for your review. BACKGROUND: In July of 2009, OCWS entered into a Memo of Understanding with Eglin Air Force Base (Eglin) to upgrade the 7th Special Forces Group (7SFG) force main in order to accommodate future wastewater flows from Duke Field, Camp Rudder, and Eglin Main Base. In September of 2012, OCWS entered into a contract with Eglin to treat the wastewater from Eglin Main Base and to construct the necessary infrastructure to transmit the wastewater. Included in this scope of work is for OCWS to design and construct a sewer pump station near the Main Base WWTP (at the Northwest Gate). This pump station will transmit wastewater from Eglin Main Base to the 7SFG force main, ultimately leading to APWRF. The new Main Base Lift Station will be owned and maintained by OCWS. Terms of the contract with Eglin allows conveyance of the wastewater from the East County/Bluewater Bay Service Area to the Main Base Lift Station. The cost to upsize this lift station to accommodate East County flows will be borne by OCWS. The agreement allows OCWS to reduce the total force main footage required to convey wastewater to the APWRF as well as the horsepower requirements needed for pumping. The benefit for Eglin is that it reduces the size of the easement needed for the force main and also eliminates a potential conflict with future planned runway construction. In April of 2012, OCWS entered into an interlocal agreement with the City of Niceville and City of Valparaiso to transfer its ownership and treatment capacity at the NVOC Regional Wastewater Treatment Facility. As part of this agreement, OCWS transferred its cost sharing responsibility of the NVOC facility, upon relocation of all of its flows from the East County/Bluewater Bay Service Area to the APWRF. As part of this relocation, OCWS would need to construct a new sanitary sewer force main and repumping station to convey its flows to the APWRF. The proposed East County Repump Station is shown as Phase 9 on the attached East County Master Sewer Plan (labeled as "Proposed College Blvd Lift Station"). The sanitary sewer force main is shown as Phase 10. Note that Eglin has agreed to the alternate route for Phase 10, constructing the force main into the Main Base Lift Station (Phase 5). OCWS has budgeted $4.5M in FY2012-2014 for the above-mentioned force main (Phase 10), repump station (Phase 9), and upsize to the Eglin Main Base Sewer Pump Station (Phase 5). This $4.5M is funded from the $15M 2012 bank loan. Similar to the approach chosen for the design of the 7SFG force main and sewer pump station, OCWS is proposing for Constantine Engineering to design the repump station and Polyengineering to design the force main. For a project this large and complex, we feel it is best for these two engineering firms to work together and review each other's work. Constantine's Task Order 70 is for the design and other professional services for the construction of a new 4.2 MGD East County Repump Station. The attached Engineering Scope of Services from Constantine Engineering includes the necessary work tasks to complete the scope of work for the design, permitting, and construction management associated with the new East County Repump Station. This Task Order 70 has been negotiated with Constantine Engineering for the necessary Scope of Services and is a not to exceed amount of $151,500.00. OPTIONS: Approve or deny. RECOMMENDATIONS: OCWS requests BCC approval to authorize the Chairman to execute Constantine Engineering Task Order 70, for a not to exceed amount of $151,500.00. RECOMMENDED BY: APPROVED BY: Ernie Padgett, County Administrator
