The U.S. Embassy in Riyadh, Saudi Arabia, requires Public Diplomacy Event Management Support Services to be performed at the embassy in the Diplomatic Quarter, Riyadh. The anticipated performance period is a base year plus two option years, if exercised by the government. The Embassy intends to award an indefinite-delivery, indefinite-quantity (IDIQ) firm-fixed-price contract to the lowest-priced, technically acceptable offeror, potentially based on initial offers without discussions. The solicitation is not yet ready for issuance and will be posted on SAM.gov when available. Offerors must be registered in SAM at the time of proposal submission, and proposals are submitted electronically to RiyadhContracting@state.gov.
