This document is an Addendum (Number 01) for Invitation for Bid (IFB) #19-IFB-1481997624-GSX issued by the North Carolina Department of Public Safety (NCDPS) Emergency Management for the Duplin County Generator Project. The addendum addresses specific questions from potential bidders regarding generator installations at three elementary schools: Beulaville Elementary, North Duplin Elementary, and Rose Hill Magnolia Elementary. The document provides clarifications on electrical configurations, transformer connections, generator placement, and site-specific installation requirements. The bid opening is scheduled for April 28, 2025, at 2:00 PM ET, with bidders required to submit turn-key project proposals that include drawings, design, and as-built documentation for each location.
The addendum emphasizes that bidders must provide comprehensive project documentation to both Duplin County and the Duplin School system upon project completion. The responses indicate flexibility from the owner regarding specific technical details, such as electrical interconnections and generator positioning, while maintaining clear expectations about project scope and execution. The project appears to be funded through hazard mitigation efforts, with a focus on ensuring emergency power capabilities at critical educational infrastructure. Contractors are instructed to follow National Electrical Code (NEC) standards and provide solutions that minimize redundant work and maximize efficiency in generator and electrical system installations.

1. It was conveyed during the site visit that the owners had already planned and signed a contract to replace the aged out 2500-amp MDP. Would the owners be willing or able to reschedule that work for the summer of 2026 to prevent the owners from paying for new feeds from the utility transformer to the new MDP and then they can be removed and replaced to incorporate the ats the very next summer?
Prefer no delays.
2. If the owners are not able to postpone the work, would they help facilitate some cooperation between the MDP changeout contractor and the winner bidder of this IFB so as to not do the same work twice and prevent waste of time and resources.
