USACE Latin America and Caribbean District seeks market research responses for a potential design-build construction project at Callao Naval Base, Lima, Peru; this is a sources sought only, not a solicitation, and no proposals are being accepted. The estimated construction magnitude is between $25,000,000 and $50,000,000, with performance expected 540 days after Notice to Proceed and anticipated award in Fiscal Year 2027 Quarter 3. The scope includes complete design-build services for multiple warehouse facilities and a quality control/administrative building, plus site infrastructure, MEP, specialized fire suppression, DBA insurance, FF&E, and host-nation permitting. The Government may use a two-phase design-build procurement, limited competition, or a qualified bidders list depending on market research; small business set-asides will not be used for this overseas procurement, but U.S. and foreign entities are encouraged to respond. Interested firms should submit comprehensive capabilities statements covering Peru experience, design-build and technical capabilities, bonding, logistics, security, and market risks.
