Request for Proposal --- Department of State Design/Build Construction Services for New Embassy Compound in Tallinn, Estonia

The Department of State’s Bureau of Overseas Buildings Operations (OBO) is issuing a two‑phase, full‑and‑open competition for Design‑Build Construction Services to construct a New Embassy Compound (NEC) in Tallinn, Estonia. The estimated design‑build cost is $250 million to $395 million. Phase I (due May 13, 2026, 3 p.m. ET, electronic submission only) requires offerors to demonstrate eligibility as a U.S. Person or U.S. Joint Venture, be registered in SAM.gov, and possess or be able to obtain the required security clearance. Offerors must submit detailed past‑performance data for four comparable projects (including entity name, location, service type, complexity, construction type, completion date, value, and percentage of work performed if a partner), inflation‑adjustment calculations, and certifications of U.S. citizenship and staffing levels. Successor entities must prove complete successor‑in‑interest status, and any multi‑entity proposal must be structured as a formal JV or prime/subcontractor arrangement. Phase II (anticipated issuance May‑June 2026) will involve a site visit and a technical‑and‑price RFP. The contractor will be responsible for preparing all design and engineering documents based on government‑provided bridging design inputs (site utilization plan, building massing, elevations, space standards, utilities, etc.), and for delivering construction labor, materials, on‑site management, quality‑control, safety plans, schedules, cost estimates, and project close‑out. Compliance with the Omnibus Diplomatic Security and Antiterrorism Act, including adequate competition and inflation‑adjusted pricing, is a critical requirement throughout the solicitation.
