Programmable Logic Controllers Redacted.pdf

This document is a Justification and Approval (J&A) for a sole-source acquisition under the simplified acquisition threshold for the Portsmouth Naval Shipyard in Kittery, Maine. The procurement involves water infrastructure upgrades, specifically requiring new Remote Terminal Units for existing sites, proposed meter sites, and upgrades to the SCADA System and pump station controls. Allen Bradley programmable logic controllers are the sole specified product, justified by their unique ability to meet the solicitation's specific needs and being the only product on the market that fulfills all requirements.

The acquisition is for solicitation N62470-25-R-0004 MILCON P1080 Design-Bid-Build, Power Reliability and Water Resiliency Upgrades. The justification emphasizes that Allen Bradley control systems dominate the market, which provides advantages in expert support, staff familiarity, and operator expertise. The shipyard cannot secure reliable support for alternative systems, and standardizing on a widely-used platform will improve system reliability, allow for a water distribution system with single control system, and enable better maintenance and parts management.
