USACE Japan District is conducting market research for a design-bid-build project to install a backup power generator supporting Building 1907 in Yokosuka, Japan. The project magnitude is between ¥500,000,000 and ¥2,000,000,000, with an anticipated period of performance of 518 calendar days. The Government intends to issue an Invitation for Bid, with a solicitation anticipated around May 2027. Participation is limited to local sources physically located and licensed/authorized to perform construction in Japan; offerors must hold a Japanese civil or architectural construction license and be SAM-registered. Interested firms are asked to provide comparable project experience, bonding levels, CMMC status, and technical feedback such as generator availability and long-lead items.
