Vallejo Flood and Wastewater District is requesting proposals for on-call Programmable Logic Controller programming, maintenance, troubleshooting, and control system support services under RFP 2026-008-TS, with proposals due September 24, 2026 at 2:00 p.m.

The scope includes PLC logic modifications for Schneider M580 and M340 systems, I/O and field device support, network communications management, HMI/SCADA updates using AVEVA System Platform and OMI, control strategy implementation, emergency response, and comprehensive documentation and testing.

Proposers must demonstrate relevant experience with at least two similar projects completed within the past five years and submit a detailed fee structure identifying all cost components including labor hours, labor rates, subcontractor costs, materials, equipment, and reimbursable expenses.
