Pre-Advertisement Notice for Hemphill Water Treatment Plant SCADA Improvement

The City of Atlanta is conducting a competitive procurement for SCADA (Supervisory Control and Data Acquisition) improvements at the Hemphill Water Treatment Plant located in Fulton County, Georgia. This pre-advertisement notice was posted on May 8, 2026, with a response deadline of May 29, 2026, and a pre-solicitation conference will be held to provide additional information and clarify scope. The project involves comprehensive modernization of the water treatment plant's control system architecture, including replacement of outdated General Electric iFix systems with Schneider Electric AVEVA Wonderware HMI systems, conversion of ControlNet networks to Ethernet/IP architecture, installation of new 5580 ControlLogix controllers, and deployment of PanelView Plus 7 Performance operator interface terminals across 16 filter consoles. Key deliverables encompass equipment procurement and installation, comprehensive network upgrades utilizing fiber optic and Cat 5E cabling (2,000 feet basis), Factory Acceptance Testing (FAT) with four days of on-site validation, five consecutive days of operational testing, three training sessions for operations personnel, and complete as-built documentation and operations and maintenance manuals. The 360-day project timeline includes eight primary tasks spanning from implementation planning through final documentation. Qualified vendors must demonstrate at least five years of experience completing comparable end-to-end integration projects with a minimum of five similar contracts completed within the past five years, maintain at least ten years in business, and provide a Project Manager with seven years of industrial controls experience and two years leading SCADA upgrades, along with a Lead Programmer/Controls Engineer with seven years of ControlLogix PLC programming and AVEVA development experience. Vendors must also demonstrate satisfactory performance on at least three prior Allen-Bradley ControlLogix PLC and SCADA upgrades at water or wastewater treatment facilities completed within five years, submit three verifiable references with performance documentation, and provide evidence of meeting project schedules. All programming personnel must complete background checks at vendor expense before accessing City of Atlanta equipment or systems.

The procurement documents do not specify set-aside designations, disadvantaged enterprise restrictions, or limitations on types of organizations that may respond. No incumbent vendors or current contractors are identified in the materials provided. The existing infrastructure requiring integration includes the current General Electric iFix SCADA system, ControlNet network architecture, existing PLC racks at multiple process areas including the low lift pump station, chemical buildings, filter building, and finished water pump station, and all current servers, workstations, and related operational equipment that must remain functional throughout the project. The City of Atlanta will provide all servers, workstations, and AVEVA licensing, perform utilities and external electrical/mechanical installation services, and retain ownership of all removed equipment and materials. The procurement documents do not contain explicit budget ranges or estimated award values; however, the comprehensive scope including equipment procurement, engineering services, integration labor, testing, and training across a 360-day implementation period suggests a substantial contract value typical of municipal water infrastructure modernization projects.
