Department of State Worldwide Design/Build and Construction Project Indefinite Delivery/Indefinite Quantity Contracts

The U.S. Department of State Office of Acquisition Management is seeking worldwide design-build and construction services for diplomatic facilities through an Indefinite Delivery/Indefinite Quantity (IDIQ) contract. The solicitation will be conducted in two phases: Phase I will evaluate offerors' minimum mandatory requirements, and Phase II will request technical and pricing proposals from eligible firms. Key contract requirements include possessing an active SAM.gov registration, holding a Secret facility security clearance, and being a U.S. firm. Potential offerors must demonstrate capabilities in renovation, site work, and new construction at various DOS facilities globally. The planned solicitation release date is June 17, 2025, with proposals subject to the Omnibus Diplomatic Security and Antiterrorism Act of 1986, as amended by the 2025 NDAA.

The contract will be divided into two categories: a small business set-aside and a full and open competition category. Up to 42 IDIQ contracts will be awarded, with seven contracts reserved for specific small business classifications including 8(a), HubZone, service-disabled veteran-owned, woman-owned, and general small businesses. Task orders under $25 million will be set aside for small businesses, while larger orders will be competed openly. Each IDIQ contract will have a minimum guarantee of $40,000 and a maximum ceiling of $800 million, structured with a one-year base period and nine additional one-year option periods. The procurement aims to commission top constructors to produce high-quality facilities, with the full solicitation expected to provide detailed evaluation criteria and specific performance requirements for potential contractors.
