Ventilation for Radon Mitigation

The Department of State seeks design, procurement, installation, testing, and commissioning of a radon mitigation ventilation system at a U.S. Embassy residential property in Stockholm, Sweden, with quotations due September 9, 2026 at 10:00 local time. The procurement carries no set-aside; the Government intends to award to the lowest-priced, acceptable, responsible offeror and will not conduct discussions unless necessary.

Place of performance is Lidingo, Stockholm, Sweden (Norrkroken 9, 181 65 Lidingo). The system must reduce indoor radon concentrations below the U.S. EPA Action Level of 148 Bq/m³ (4.0 pCi/L) and includes an air handling unit with heat pump, heat recovery wheel, insulated ductwork, controls integration with existing geothermal systems, electrical work, closet and architectural finishing, and post-installation radon verification testing. The contract period is one year from award. NAICS code is 238220, Plumbing, Heating, and Air-Conditioning Contractors; PSC code is Z1JZ, Maintenance Of Miscellaneous Buildings.

A mandatory site visit is scheduled for August 27, 2026 at 12:30 local time; prospective quoters must notify the Stockholm Procurement Team (stkgsocontracts@state.gov) by August 19 at 10:00 with visitor names and to arrange entry. For solicitation values above $40,000, offerors must be registered in SAM with a valid UEI number at time of quotation submission; failure to register renders the proposal non-responsible. Quotations must be submitted electronically in English and include evidence of established business operations in Sweden, past performance references, personnel qualifications, proof of necessary licenses and permits, a strategic maintenance plan, insurance documentation, and representations regarding small business status and compliance certifications. Value Added Tax will be priced separately from contract line item pricing. All work must comply with Swedish building codes and labor laws; standard work hours are Monday–Friday, 09:00–16:00, with no work permitted on weekends or holidays.
