Programmable Logic Controller (PLC) Replacement and Modifications to Supervisory Control and Data Acquisition (SCADA).

The City of Santa Fe, on behalf of the Buckman Direct Diversion (BDD), is seeking professional services for a Programmable Logic Controller (PLC) replacement and Supervisory Control and Data Acquisition (SCADA) system modification project. The procurement, identified as RFP #FY26-RFP-036, targets the replacement of four critical PLCs: Pall Membrane, Ozone, Advanced Treatment Facility, and Granulated Activated Carbon. Contractors must provide comprehensive services including labor, equipment, materials, programming expertise, installation, integration, testing, documentation, and operator training, using Schneider Electric Unity Pro XL software. The project requires all replacement work to be scheduled between October and March during low-demand periods to minimize operational disruption. Evaluation criteria will assess proposals using a best-value approach, with 35% weight on Scope/Level of Expertise Plan, 10% on Value Added Plan, 30% on Cost Proposal, and 25% on Interview performance. Key procurement dates include a non-mandatory pre-proposal meeting on December 2, 2025, written questions due by December 4, 2025, and proposal submissions required electronically via the OpenGov Procurement Portal by December 18, 2025, at 3:00 PM.

The procurement allows for local preference considerations, with Santa Fe resident businesses potentially receiving 3-6% additional evaluation points if certified by the New Mexico Taxation and Revenue Department. Subcontractors are permitted with prior written City approval, though the prime contractor remains fully responsible for contract performance. The existing infrastructure requires integration with Schneider Electric systems, specifically replacing legacy Quantum PLCs with M580 PLCs across 13 water system sites. While a specific budget range is not explicitly stated, the contract will include compensation for control system drawings, hardware procurement, installation, programming, testing, commissioning, training, and both emergency and routine on-call services. Mandatory submission requirements include Campaign Contribution Disclosure Forms, Conflict of Interest Statements, Non-Collusion Affidavits, and Responsibility Disclosures. The contract will have an initial one-year term with potential renewal options not to exceed ten years, and contractors must maintain specific insurance levels, including $2,000,000 commercial general liability and $1,000,000 business automobile liability insurance.
