Eastern Municipal Water District (EMWD) is soliciting proposals through Request for Bid (RFB) #3889 for the procurement of a new Motor Control Center (MCC) and Main Switchboard (MSB) to replace existing equipment at the Brosseau Booster location in Riverside County, California. The procurement specifically requires a complete MCC and MSB in a white NEMA 3R enclosure, including a utility pull section, utility meter section, and solid-state main breaker. An ASCO Automatic Transfer Switch rated at 225 amps is mandated, with the Reduced Voltage Soft Starter (RVSS) required to be manufactured by Toshiba, ABB, Allen Bradley, or Schneider Electric. A mandatory pre-bid site inspection is scheduled for 10:00 AM on October 16, 2025, at the Brosseau Booster location, with electronic bids due by 5:00 PM on October 30, 2025. The district will evaluate responses based on responsiveness to requirements, bidder capability, and pricing, with a bid award anticipated on November 6, 2025, and contract approval targeted for November 13, 2025. EMWD emphasizes that this procurement is equipment-only, with no installation, startup, or arc-flash analysis required from the supplier.

No specific set-aside designations or restrictions on responding organizations are mentioned in the documentation. The bid requires all materials to be new, unused, and represent the most recent upgrade in modern engineering design. EMWD reserves the right to purchase up to an additional 100% of the specified quantity within 90 days of the award. Suppliers must provide monthly updates on assembly and delivery status, along with estimated delivery dates, and submit comprehensive operation and maintenance manuals. The equipment must come with a manufacturer's warranty. While no specific budget range is explicitly stated, the procurement involves critical infrastructure replacement for a water district pumping station. Bidders must demonstrate technical capability to provide specialized electrical control equipment meeting precise specifications, with the district maintaining the right to reject any bid that does not meet their comprehensive criteria.
