Body
BACKGROUND
The City of Dallas Water Utilities Department (DWU) owns and operates three water treatment plants - Bachman, Elm Fork, and East Side - which have a combined treatment capacity of over 900 million gallons per day. DWU evaluated the condition of its water production facilities and identified key facilities and equipment that need to be rehabilitated or replaced. On August 12, 2020, the City Council authorized a professional services contract with Alan Plummer & Associates, Inc. dba Plummer Associates, Inc., for the evaluation and design of high priority major maintenance improvements at each water treatment plant. As these treatment facilities and the associated equipment age, regulatory requirements and operational conditions change, and technology improves, treatment facilities and equipment need to be rehabilitated or upgraded to ensure reliable and quality water service to our customers.
On September 22, 2021, the City Council authorized Supplemental Agreement No. 1 to the professional services contract for the design of additional critical items identified during the evaluation process. These included additional electrical and instrumentation equipment upgrades and replacements, modifications to chemical facilities, and expansion to the process laboratory. It also provided services for construction administration of prioritized items grouped in the construction package that was awarded on September 14, 2022. On September 27, 2023, the City Council authorized Supplemental Agreement No. 2 to the professional services contract to perform application programming services and bid assistance related to the advertisement of the East Side Laboratory Improvements.
This action will authorize Supplemental Agreement No 3 for construction phase services associated with the East Side Water Treatment Plant Laboratory Renovation Project. The East Side Water Treatment Plant (ESWTP) has a current treatment capacity of 440 million gallons per day and is the largest of three water treatment plants serving customers of the City of Dallas. The plant was originally constructed in 1962 with a capacity of 100 million gallons per day, which included the laboratory located on the second floor of the administration building. Since that time only minor renovations and reconfigurations of the administration building have occurred, and the laboratory footprint has remained much the same as when it was originally constructed. A construction contract for the ESWTP laboratory renovation is scheduled for City Council approval on September 11, 2024. The scope of work includes a complete renovation of existing laboratory facilities (second floor), buildout of the ground level below the laboratory to provide more space for the additional equipment, renovation of adjacent men's and women's restrooms to provide Americans with Disabilities Act and Texas Accessibility Standard compliance, and handicap accessible control updates for the elevator.
Approval of this supplemental agreement will ensure that Alan Plummer, the design engineer, is under contract to provide construction administration services including review of contractor submittals, responding to contractor requests for information, review of contractor change requests during construction, and preparation of record drawings for the completed improvements.
