About this file

This is a proposal sheet from Ring Power Corporation Advanced Electrical Services for the Eastern Water Reclamation Facility (EWRF) Modernization project submitted to Orange County Wastewater Utilities in Orlando, Florida. The proposal encompasses a comprehensive PLC modernization and controls retrofit for project 36148, which includes removing existing 3.S Controllers and replacing them with Schneider Electric PLCs and PowerPlex II transducers operating on an ethernet communication network. The scope of work encompasses modernization of switchgear controls for four generator sections and tie systems, replacement of obsolete GE protective relays with modern SEL 700G and 751 multifunction relays, installation of new HMI workstation and remote server capabilities, replacement of two utility control lineups (GTA and GTB), addition of new 48 VDC battery systems with nickel-cadmium batteries, and preventative maintenance on medium-voltage breakers. The onsite work is estimated at twenty-six consecutive days during standard business hours and weekends, with the proposal valid for forty-five days from issuance. The project schedule is referenced in relation to the Orange County solicitation deadline of April 23, 2026, with sealed responses required via the OpenGov e-Procurement Platform.

The total project cost is $2,267,882.47 plus applicable taxes and fees, with freight included in the proposal on FOB Origin terms. The proposal includes optional adders for a Factory Witness Test and spare parts list, with an extended warranty option available extending coverage to 60 months for equipment and 66 months for labor upon annual preventative maintenance after year 2. Standard warranty coverage provides 12 months from startup completion for equipment and materials or 90 days from startup for onsite labor and workmanship. The proposal assumes retained settings and does not include a site coordination study or independent third-party testing, both of which would require separate proposals. Additional clarifications address responsibilities for emergency backup power, utility coordination, waste disposal, conduit and field wiring provision, site safety training, and COVID-19 restrictions, all of which are noted as not included unless separately proposed.
