Pre-Advertisement Notice for Hemphill Water Treatment Plant SCADA Improvement

The City of Atlanta is initiating a competitive solicitation for SCADA system modernization at the Hemphill Water Treatment Plant, aiming to replace outdated ControlNet infrastructure with Ethernet/IP and migrate from GE iFix to the AVEVA System Platform to enhance operational reliability and process automation. The project requires a contractor with proven experience in SCADA upgrades for water treatment facilities, particularly those involving Allen-Bradley ControlLogix PLCs and AVEVA HMI platforms, with a minimum of three similar projects completed in the past five years and a track record of uninterrupted plant operations during implementation. The contractor must demonstrate technical expertise through detailed project approach narratives covering network migration, cybersecurity, firmware compliance, and operational continuity strategies, while ensuring all key personnel—Project Manager and Lead Programmer—meet stringent experience requirements and pass background checks per City protocols. All equipment must be packaged and stored with moisture protection until delivery to the plant site in Georgia, and the contractor is responsible for comprehensive deliverables including Factory Acceptance Testing, commissioning, five consecutive days of operational testing with City personnel, training for operations and maintenance staff across all shifts, and submission of As-Builts and O&M manuals in electronic PDF format within 30 days of system commissioning. The solicitation mandates strict adherence to UL-508A panel fabrication practices without requiring re-labeling, and requires the contractor to supply 20% spare I/O components and provide lodging and meals for three City representatives during FAT. Subcontracting is prohibited without prior written approval, and no deviations from the Statement of Work are permitted without COA authorization. All removed equipment remains City property, and failure to meet any minimum requirement results in automatic disqualification. The proposal must include firm experience documentation, three verifiable project references, resumes of key personnel, and detailed FAT and C&SU plans, submitted electronically in PDF format by the May 29, 2026 deadline. The contract is structured as a firm-fixed-price arrangement, though not formally designated, with performance milestones tied to a 360-day timeline from Notice to Proceed, and no pricing information or contract value is disclosed in the solicitation materials.
