DESCRIPTION/BACKGROUND:
On March 21, 2023, the Board approved a contract with Ardurra Group, Inc. to provide engineering services for the Southwest Service Area Wastewater Treatment Facility Project Design. The scope of this first phase included evaluating the current and projected wastewater treatment capacity needs within the southwest service area and identifying the most appropriate short-term and long-term solutions.
On August 20, 2024, the Board approved Contract Amendment 1, which authorized Phase II of the project. Phase II includes design, permitting, and bidding assistance for the expansion of the Oak Run Wastewater Treatment Plant from 1.6 million gallons per day (MGD) to 3.5 MGD treatment capacity. This phase also includes the design and bidding of early work operations and maintenance components to enhance existing plant operations prior to construction of the expansion. Additionally, preparation of the Annual Capacity Analysis Report, as required by the current Wastewater Treatment Permit, was incorporated into the scope of services.
Change Order 1 was executed on October 10, 2024, reducing the Purchase Order amount to offset a payment that had been made to the vendor in the amount of $42,492 while the purchase order was pending.
Change Order 2 was executed on December 11, 2024, to correct the vendor number assigned to the Purchase Order.
Change Order 3, presented for Board consideration today, provides additional professional engineering services, which include grant administration services; evaluation of equalization tank/odor control; biosolids and phasing evaluations; conversion of the existing peak shaving tank to an equalization tank; evaluation and incorporation of odor control improvements; relocation of the biosolids building and digester; addition of new process units, filters, and a contact basin; construction of a new reject pond; development of a new Drainage Retention Area (DRA); and construction of new access roads within the site.
The Change Order and detailed proposal are attached for review. Upon approval at today’s meeting, the Change Order will be presented to the Chairman for signature.
BUDGET/IMPACT:
