The U.S. Department of State is soliciting proposals for Design-Build Construction Services to create a new Controlled Access Area (CAA) Annex at the Embassy Compound in Nairobi, Kenya. This project, which is part of the Bureau of Overseas Buildings Operations (OBO), involves constructing a 12,500 GSM facility with six levels, including essential offices, meeting rooms, and security enhancements, in compliance with the Omnibus Diplomatic Security and Antiterrorism Act. The estimated construction cost ranges from $175 million to $250 million, and interested contractors must demonstrate relevant past performance, possess a Defense Counterintelligence and Security Agency (DCSA) Secret facility clearance, and be registered in SAM.gov. Proposals are due by April 7, 2025, and inquiries can be directed to primary contact Jose Vasquez at vasquezj4@state.gov or secondary contact Blondell Taylor at taylorbk2@state.gov.
