Pre-Advertisement Notice for Chattahoochee Water Treatment Plant SCADA Improvement

The City of Atlanta is soliciting qualified vendors to perform comprehensive upgrades and modernization at the Chattahoochee Water Treatment Plant, focusing on the replacement of legacy ControlNet communication networks with Ethernet/IP infrastructure and the migration from GE iFix HMI systems to the AVEVA System Platform. The project requires the installation of new ControlLogix PLCs, I/O modules, communication hardware, and software integration, all while ensuring uninterrupted plant operations. Vendors must deliver a fully commissioned and tested control system, including Factory Acceptance Testing conducted at their facility and subsequent onsite commissioning and five consecutive days of operational testing at the plant. Key deliverables include an implementation plan, approved shop drawings, as-built documentation, operation and maintenance manuals in electronic format, and comprehensive training for operations and maintenance staff across all shifts. All equipment removed during the project becomes the property of the City, and vendors are responsible for moisture protection, secure handling, and coordination of climate-controlled storage until delivery. Vendors must demonstrate a proven track record with similar SCADA and PLC upgrade projects, including five completed projects within the past decade, and must submit detailed resumes for a project manager with at least seven years of industrial controls experience and a lead programmer with seven years of hands-on experience in ControlLogix and AVEVA platforms. All programming personnel are subject to mandatory background checks, with results submitted to the City prior to system access. The contract requires strict adherence to UL-508A standards for control panels, use of the latest firmware and software versions, and compliance with the technical specifications in Exhibit A. The project timeline extends to 360 days from the Notice to Proceed, with critical milestones including equipment delivery at day 240 and final documentation submission by day 360. The City will witness all FATs and requires the vendor to cover lodging and meals for three city employees during a four-day test period with 14 days’ notice. Submissions must be in PDF format for technical documents, include three project references and a detailed Schedule of Values, but no contract value is disclosed. No formal FAR clauses, evaluation factor weights, or socioeconomic set-asides are specified, and the basis of award remains undisclosed. All deviations from the scope require written approval, and no contract options or formal changes clauses are defined beyond a contingency task included in the payment schedule.
