USACE is exploring Progressive Design-Build and Integrated Design & Construction for the upcoming electrical substation project at Yokohama North Dock, Japan, and is conducting market research to gauge local industry interest. The project is the FY28 Frequency Converter Plant, with a magnitude between ¥7,500,000,000 and ¥15,000,000,000, and will construct a new 66kV substation/frequency converter plant providing 60Hz shore power for U.S. military watercraft. Work will be performed in its entirety in Japan and is intended only for local sources physically located and licensed/authorized to perform construction in Japan. Interested firms, including joint ventures, must be registered in SAM and must hold a Japanese civil construction (doboku isshiki koji) or Japanese architectural construction (kenchiku isshiki koji) license. The selected contractor and Government would collaboratively develop design, schedule, and cost under these alternative delivery methods.

The U.S. Army Corps of Engineers is exploring alternative acquisition strategies—Progressive Design-Build and Integrated Design & Construction—for a planned FY28 project to construct a new 66kV electrical substation and frequency converter plant at Yokohama North Dock, Japan. The project will provide permanent 60Hz shore power for U.S. military watercraft, including the main facility, supporting utilities, site improvements, cybersecurity, and fire protection. The estimated cost magnitude is between ¥7,500,000,000 and ¥15,000,000,000 Japanese Yen. This market survey is intended only for local sources physically located and authorized to conduct construction business in Japan, holding a Japanese civil construction or architectural construction license. Interested firms must be registered in SAM, and responses will be used for market research and acquisition decision-making.
